Exam 2 Review (All Folder NOTES Combined)

Overview of the Musculoskeletal System

• Components of the System: The musculoskeletal system is comprised of:

  • Bones

  • Joints

  • Muscles

  • Ligaments

  • Tendons

  • Connective tissues

• Skeletal Functions:

  • Provides body structure.

  • Protects internal organs.

  • Storage of minerals and fats.

  • Blood cell production.

• Muscle Functions:

  • Produces movement.

  • Stabilizes joints.

  • Generates heat.

  • Maintains posture.

• Bones and the Renal Connection:

  • Erythropoietin (a renal hormone) stimulates bone marrow for Red Blood Cell (RBC) production.

  • Renal failure patients cannot produce erythropoietin, which causes anemia because the red bone marrow is not sufficiently stimulated.

• Types of Connective Tissue:

  • Tendon: Connects muscle to bone. Remember: "T for two types."

  • Ligament: Connects bone to bone. Remember: "L for like to like."

  • Cartilage: Covers the end of the bone. Remember: "C for cap of bone."

  • Fascia: Connective tissue that covers the epimysium.

• Specific Injuries:

  • Strain: Injury to a tendon or muscle.

  • Sprain: Injury to a ligament.

Anatomy of Bone and Muscle

• Management:

  • Bisphosphonates (Alendronate) to inhibit osteoclasts.

  • Weight-bearing exercises.

  • Fall precautions (call bell, bed alarm).

• Components of the System: The musculoskeletal system is comprised of:

  • Bones: Rigid structures that make up the skeleton, providing support and protection for internal organs, as well as facilitating movement through attachment to muscles.

  • Joints: Connections between bones that allow for movement and flexibility, classified into different types such as synovial, fibrous, and cartilaginous joints, each with distinct characteristics and movements.

  • Muscles: Composed of muscle fibers that contract to produce movement; muscles are categorized into three types: skeletal (voluntary control), smooth (involuntary control in organs), and cardiac (involuntary control in the heart).

  • Ligaments: Strong, fibrous connective tissues that connect bones to other bones, aiding in stability and support in joints.

  • Tendons: Connective tissues that attach muscles to bones, playing a crucial role in enabling movement by transmitting forces generated by muscle contractions.

  • Connective Tissues: Includes cartilage (providing cushioning at joints), fascia (surrounding muscles), and synovial membranes (lining joint cavities).

• Skeletal Functions:

  • Provides body structure: The skeleton gives the body its shape and protects vital organs.

  • Protects internal organs: Ribs safeguard the heart and lungs; the skull protects the brain; the vertebral column encases the spinal cord.

  • Storage of minerals and fats: Bones serve as reservoirs for minerals such as calcium and phosphorus and fat storage in yellow marrow.

  • Blood cell production: Bone marrow is the site of hematopoiesis, producing red blood cells, white blood cells, and platelets.

• Muscle Functions:

  • Produces movement: Muscles contract to enable voluntary and involuntary movements, from walking to heartbeats.

  • Stabilizes joints: Muscles help to maintain joint stability during activities and support posture.

  • Generates heat: Muscle activity generates heat, aiding in thermoregulation of the body.

  • Maintains posture: Constant tension in muscle maintains posture against gravity.

• Bones and the Renal Connection:

  • Erythropoietin (a renal hormone) stimulates bone marrow for Red Blood Cell (RBC) production; it is crucial in response to hypoxia (low oxygen levels).

  • Renal failure patients cannot produce erythropoietin normally, leading to reduced RBC synthesis, which can result in anemia due to insufficient oxygen carrying capacity in the blood.

• Types of Connective Tissue:

  • Tendon: Connects muscle to bone; plays a vital role in the biomechanics of movement—"T for two types" (muscle to bone).

  • Ligament: Connects bone to bone; provides structural stability to joints—"L for like to like" (bone to bone).

  • Cartilage: A flexible tissue covering the ends of bones at joints; absorbs shock and reduces friction during movement—"C for cap of bone".

  • Fascia: A connective tissue that provides support and protection to muscles, nerves, and blood vessels—essential for structural integrity and movement efficiency.

• Specific Injuries:

  • Strain: A muscle or tendon injury resulting from overstretching or excessive force; symptoms include pain, swelling, and limited movement.

  • Sprain: An injury to a ligament caused by twisting or overstretching; characterized by pain, swelling, bruising, and impaired movement.

Osteoarthritis (OA) Overview and Pathophysiology

• Definition and Nomenclature: Osteoarthritis is recognized as the most common type of arthritis. It is also referred to as Degenerative Joint Disease (DJD).

• Pathophysiology:

  • Characterized by the progressive loss of articular cartilage within the joints.

  • Progressive deterioration leads to joint pain and significant loss of function.

  • Osteophytes: The formation of bone spurs, known as osteophytes, is a hallmark of the disease.

  • Crepitus: As cartilage disintegrates, pieces of bone and cartilage can become "loose" or "float" within the synovial joint space. This results in crepitus, a grating sound or sensation produced by friction between bone and cartilage.

  • Inflammation and Friction: Friction within the synovial joint leads to inflammation and pain.

Assessment and Clinical Manifestations of Osteoarthritis

• "Noticing" through History and Physical: Assessment includes a comprehensive history and physical examination to identify clinical manifestations.

• Joint Specificity: OA typically affects weight-bearing joints (e.g., hips, knees). It can manifest in a unilateral, single-joint fashion.

• Psychosocial Impact: Severe, chronic pain associated with OA may lead to psychological complications such as depression and anxiety.

• Physical Findings:

  • Heberden's Nodes: Bony overgrowths at the distal interphalangeal (DIP) joints.

  • Fusiform Swelling: General swelling of the joints.

Diagnostic Testing for Osteoarthritis

• Laboratory Values:

  • Erythrocyte Sedimentation Rate (ESR): May be normal or only slightly elevated.

  • High-Sensitivity C-Reactive Protein (hsCRP): Utilized to identify markers of inflammation.

  • Antinuclear Antibody (ANA): Typically remains normal in OA patients (unlike Rheumatoid Arthritis).

• Imaging and Other Diagnostics:

  • Magnetic Resonance Imaging (MRI).

  • Computed Tomography (CT) studies.

Management of Osteoarthritis

• Primary Collaborative Problems:

  • Chronic pain resulting from joint swelling and structural deterioration.

  • Potential for decreased mobility due to joint pain and muscle atrophy.

• Nonsurgical Management - Drug Therapy:

  • Acetaminophen (Tylenol): Common first-line therapy.

  • Topical Drugs: Such as Lidocaine cream.

  • Muscle Relaxants: Used for associated muscle spasms.

  • Integrative Therapies: Glucosamine and chondroitin supplements.

• NSAID Therapy Details:

  • Monitoring: Requires baseline Complete Blood Count (CBC), Basic Metabolic Panel (BMP) to check kidney function, and Liver Function Tests.

  • COX-2 Inhibitors: Celecoxib (Celebrex) is the first choice for COX-2 inhibition unless the patient has pre-existing hypertension, kidney disease, or cardiovascular disease.

  • Older NSAIDs: Ibuprofen can cause serious side effects including gastrointestinal bleeding and acute kidney failure.

• Nonsurgical Lifestyle and Modality Interventions:

  • Positioning, rest, and immobilization.

  • Thermal modalities (heat/cold therapy).

  • Weight control to reduce stress on weight-bearing joints.

• Surgical Management:

  • Total Joint Arthroplasty (TJA) or Total Joint Replacement (TJR).

  • Arthroscopy: Minimally invasive joint examination and repair.

  • Osteotomy: Surgical cutting of bone to realign the joint.

Postoperative Care: Total Hip Arthroplasty (THA)

• Patient Collaboration: Nurses must collaborate with the patient and family as "safety partners" to prevent post-op complications.

• Continuous Passive Motion (CPM): A machine is often used to provide continuous movement to the joint to improve range of motion and prevent stiffness.

Rheumatoid Arthritis (RA) Clinical Profile

• Systemic Symptoms:

  • Pain and stiffness affecting more than one joint.

  • Significant morning joint stiffness.

  • Joint tenderness and swelling.

  • Decreased range of motion.

  • Systemic effects including fatigue, malaise, and a low-grade fever.

  • Boutonniere deformity of the thumb.

  • Ulnar deviation of the metacarpophalangeal joints of the fingers.

  • Swan-neck deformity.

• Disease Progression: Characterized by a symmetric appearance of the disease process (affecting the same joints on both sides of the body).

Case Study and Discussion: Rheumatoid Arthritis

• Initial Assessment Questions:

  • Duration of symptoms and how long it takes to achieve full mobility in the morning.

  • Presence of systemic symptoms such as weight loss or fever.

  • Identification of specific painful joints.

• Patient Education on Prognosis: RA is not a condition that "goes away"; it is a chronic condition characterized by remissions and exacerbations ("flares"). Exacerbations are often triggered by stressors (e.g., loss of a family member).

• Drug Therapy - Hydroxychloroquine:

  • Onset: May take several months to reach full effectiveness.

  • Side Effects: Mild stomach discomfort, light-headedness, or headache.

  • Adverse Effect (Serious): Retinal damage. Patients must report blurred vision or headaches immediately.

  • Monitoring: Required eye examination before starting the drug and every $6$ months thereafter to detect changes in the cornea, lens, or retina.

• Drug Therapy - Prednisone:

  • Tapering: Given as a taper where the initial dosage is high and the number of pills is reduced daily.

  • Timing: Should be taken in the morning due to potential energy bursts and sleeplessness (insomnia).

• Drug Therapy - Methotrexate:

  • Side Effects: Hair loss (alopecia).

  • Immune Suppression: Report any fever or signs of infection to the provider immediately.

  • Reproductive Safety: Pregnancy is not recommended due to birth defects; birth control is mandatory while on this drug.

  • Supplementation: Folic acid is often prescribed alongside methotrexate to reduce side effects.

• Nursing Interventions for Activities of Daily Living (ADLs):

  • Promote independence by suggesting alternative and creative methods for ADLs. Do not perform tasks for the patient unless they ask, as maintaining independence is highly valued.

  • Referral to an Occupational Therapist (OT) is appropriate if modified methods are unsuccessful.

Osteoporosis: Clinical Cues and Diagnostics

• Risk Factors: Age, genetics, culture, diet (calcium/Vitamin D intake), and activity levels.

• Physical Manifestations: Significant loss of height over time (e.g., an individual may shrink from $5'6"$ at age $40$ to $4'3"$ by age $70$ due to vertebral changes).

• Diagnostic Testing:

  • DEXA scan: Dual-energy X-ray absorptiometry to measure bone mineral density.

  • Laboratory tests and regular imaging.

• Prioritizing Care: Focus on bone strength, risk for fracture, injury prevention, nutritional status, and psychosocial well-being.

Osteoporosis Prevention and Management

• Bone Building: Crucial for young people to build peak bone mass.

• Dietary Needs: Adequate intake of Calcium and Vitamin D.

• Sun Exposure: Encouraged to promote Vitamin D synthesis, provided the patient does not burn.

• Beverage Limitations: Patients should limit the intake of carbonated beverages.

• Exercise: Encourage weight-bearing exercises, but advise the patient to avoid high-impact "jarring" exercises.

• Safety: Implementation of safety precautions to prevent falls and fractures.

Osteomyelitis: Characteristics and Interventions

• Characteristics: Patients present with pain, fever, swelling, erythema (redness), and heat at the site of infection.

• Classification: Can be acute or chronic.

• Medical Interventions:

  • Antimicrobials: Aggressive antibiotic therapy.

  • Hyperbaric Chamber: Utilized for chronic cases to promote healing through high-pressure oxygen.

  • Isolation: Contact isolation is required if there is copious wound drainage.

• Surgical Management:

  • Incision & Drainage (I&D).

  • Wound debridement: Removal of infected or necrotic tissue.

  • Bone excision: Removal of infected bone segments.

Comparison of Osteoarthritis (OA) and Rheumatoid Arthritis (RA)

• Stiffness: RA is characterized by significant morning stiffness; OA involves stiffness that usually improves after the first few minutes of movement or worsens with activity later in the day.

• Joint Involvement: OA involves weight-bearing joints and can be unilateral; RA is typically symmetric and affects multiple joints.

• Labs: RA shows elevated ANA and ESR; OA typically shows normal ANA and normal/slightly elevated ESR.

• Definition and Nomenclature: Osteoarthritis is recognized as the most prevalent form of arthritis, affecting millions of people worldwide. It is also referred to as Degenerative Joint Disease (DJD). OA can result in the degeneration of joint cartilage, leading to pain, swelling, and reduced mobility.

• Pathophysiology: - Characterized by the progressive loss of articular cartilage within the joints, which serves to cushion the ends of the bones.

  • This progressive deterioration not only leads to joint pain but also results in significant loss of function, impacting the daily activities of individuals. As the cartilage breaks down, it becomes less able to handle stress, leading to increased friction and inflammation.

  • Osteophytes: The formation of bone spurs, known as osteophytes, is a hallmark of the disease. These bony projections can lead to reduced joint space and further impairment of joint function.

  • Crepitus: As cartilage disintegrates, pieces of bone and cartilage can become "loose" or "float" within the synovial joint space. This results in crepitus, recognized as a grating sound or sensation produced by friction between bone and cartilage, often noticeable during movement.

  • Inflammation and Friction: The increased friction within the synovial joint contributes to inflammation, which is often characterized by redness, warmth, and swelling around the joint area. Over time, chronic inflammation can lead to additional joint damage and exacerbate the symptoms experienced by individuals with OA.

• Risk Factors: Including advanced age, obesity, previous joint injuries, repetitive stress on the joint from certain occupations or sports, and genetic predisposition, all contribute to the progression of osteoarthritis. Lifestyle factors such as physical inactivity may also increase risk.

   Questions & Discussion

   • Case Study Question 1: A 45-year-old female reports fatigue, joint pain, and morning stiffness. What assessment questions are asked?

     • Answer: Ask how long it has been happening; how long it takes to begin fully moving in the morning; presence of weight loss or fevers; and identifying which specific joints hurt.

   • Case Study Question 2: The client with RA believes medicine will make the condition "go away." What is the nursing response?

     • Answer: Respond that the condition does not go away but can be effectively managed with drug therapy and lifestyle modifications.

   • Case Study Question 3: The provider prescribes a prednisone taper and continued hydroxychloroquine during an RA flare. What is the response to the client wondering if they need a different medication?

     • Answer: Refer to the provider for evaluation and explain that RA is characterized by remissions and exacerbations ("flares"), often triggered by stressors like loss/grief.

   • NCLEX Practice Question 1: A client with RA has difficulty with Activities of Daily Living (ADLs). What is the appropriate response?

     • Answer: "May I show you an alternative method?" The nurse should suggest alternative and creative methods to maintain independence rather than doing the tasks for the patient or referring to OT immediately.

   • NCLEX Practice Question 2: What assessment data is anticipated in a client with OA?

     • Answer: Involvement of weight-bearing joints. OA affects weight-bearing joints and can be unilateral; RA is symmetric and involves elevated ANA/ESR.

   • NCLEX Practice Question 3: What teaching is provided for Methotrexate? (Select all that apply)

     • Answer: Hair loss may occur; Report a fever to the health care provider; Use methods of birth control while on this drug. (Note: Take with Folic acid, not Vitamin C; Grapefruit juice does not affect it).

   • Definition: Osteoarthritis (OA), also referred to as Degenerative Joint Disease (DJD), is recognized as the most common type of arthritis, characterized by the degeneration of joint cartilage and underlying bone. OA typically affects older adults but can occur in younger individuals due to joint injury or overuse.

   • Pathophysiology:

     • OA is marked by the progressive loss of articular cartilage, which cushions joints and absorbs shock.

     • As the cartilage deteriorates, there is also a progressive deterioration of the joint structure leading to instability and pain.

     • Formation of Osteophytes (bone spurs) occurs as the bone attempts to repair itself, which can further contribute to joint pain and stiffness.

     • The disintegration of cartilage can lead to fragments of both bone and cartilage that "float" within the joint space, exacerbating inflammation and pain.

     • Crepitus, described as a grating sound or sensation, arises from friction between roughened bone and cartilage fragments in the affected joint.

   • Anatomical Changes:

     • In OA, synovial joints contain Type A synovial cells that are responsible for clearing debris and Type B cells that produce synovial fluid to lubricate the joint.

     • There is a progressive loss of articular cartilage which serves to protect the underlying bone.

     • In the late stages of OA, bony growths known as Heberden's nodes can develop at the distal joints of the fingers, while fusiform swelling of the joints, characterized by a spindle-like shape, can be a common external manifestation of the disease.

   Assessment and Analysis of Osteoarthritis

   • Assessment ("Noticing"):

     • History: A thorough review of the patient's medical history including previous injuries, family history of arthritis, and lifestyle factors such as occupation or activities that may contribute to joint stress.

     • Physical Assessment: Observe symptoms such as joint swelling, tenderness, and morning stiffness that typically subside with movement.

     • Psychosocial Impact: Chronic pain associated with OA can significantly impact quality of life, leading to emotional responses such as depression and anxiety, particularly in individuals unable to partake in normal activities.

   • Laboratory Diagnostics:

     • Erythrocyte Sedimentation Rate (ESR) helps to assess inflammation in the body, though it may not be significantly elevated in OA.

     • High-sensitivity C-reactive protein (hsCRP) is used to detect inflammatory activity and may be elevated in cases of acute joint inflammation.

   • Radiographic and Other Imaging:

     • Magnetic Resonance Imaging (MRI) can provide detailed images of cartilage, bone, and soft tissue.

     • Computed Tomography (CT) studies offer clear images of complex joint structure and help in evaluating joint deformity.

   • Primary Collaborative Problems (Interpreting):

     • Chronic pain is often reported due to joint inflammation, swelling, and deterioration coupled with reduced mobility due to pain and muscle atrophy stemming from decreased activity levels.

   Management of Osteoarthritis

   • Nonsurgical Management - Drug Therapy:

     • Acetaminophen (Tylenol) is often the first choice for pain control due to its safety profile.

     • Topical Drugs: Lidocaine and other topical analgesics can be applied directly to painful joints.

     • Muscle Relaxants may be prescribed to alleviate associated muscle spasms and tension.

     • Nonsteroidal Anti-inflammatory Drugs (NSAIDs):

       • Baseline Requirements: Clinicians must assess kidney function through a Complete Blood Count (CBC), Basic Metabolic Panel (BMP), and Liver Function tests prior to initiating therapy.

       • COX-2 Inhibitors provide targeted pain relief with potentially fewer gastrointestinal side effects.

       • Celecoxib (Celebrex) is often considered the first-choice NSAID, bearing in mind contraindications such as hypertension and existing cardiovascular issues.

       • Older NSAIDs (e.g., Ibuprofen) pose a risk of severe gastrointestinal complications (e.g., bleeding) and potential kidney damage.

   • Nonsurgical Management - Physical and Integrative Therapies:

     • Incorporating methods such as proper positioning, adequate rest, and immobilization of affected joints can provide symptomatic relief.

     • Thermal modalities (application of heat or cold) can alleviate pain and increase mobility.

     • Weight management is essential in reducing joint stress, thereby improving functionality and comfort.

     • Integrative therapies, such as Glucosamine and Chondroitin supplementation, may provide symptomatic relief but require further research for efficacy.

   • Surgical Management:

     • Options include Total Joint Arthroplasty (TJA), also known as Total Joint Replacement (TJR), which is frequently recommended for severe cases.

     • Arthroscopy can be performed to remove loose fragments, smooth damaged cartilage, or repair the joint.

     • Osteotomy involves reshaping bone to shift weight from an damaged area.

   • Postoperative Care:

     • Utilizing Continuous Passive Motion (CPM) machines can facilitate joint mobility post-surgery.

     • It is essential for nurses to collaborate with patients, fostering a partnership around safety to mitigate potential complications following surgery.

   • During seizures: protect from injury, do not restrain, do not place anything in the mouth.

   • After strokes (CVAs): prevent falls, skin breakdown, aspiration, and injury.

   • Clients with visual deficits (hemianopsia) need a safe home environment.

   • Suspected spinal cord injury: immobilize and minimize movement.

   NCLEX rule: When in doubt, ask yourself: "What keeps the patient safest right now?"

• Components of the System: The musculoskeletal system is a complex, interconnected network comprising:

  • Bones: Rigid structures forming the skeleton, responsible for providing shape and support to the body, protecting vital internal organs, and facilitating movement through attachment to muscles. Bone is a living tissue that constantly undergoes remodeling through the processes of ossification and resorption.

  • Joints: Connections between bones that enable movement and flexibility. Joints are classified into three primary types: synovial (freely movable, such as the knee and elbow), fibrous (immovable, like those in the skull), and cartilaginous (slightly movable, such as intervertebral discs). Each joint type has unique features that influence mobility and stability.

  • Muscles: Composed of muscle fibers capable of contraction, muscles are responsible for producing movement, maintaining posture, and generating heat through metabolic processes. Muscles are categorized into three types: skeletal (voluntary and striated), smooth (involuntary and found in organs), and cardiac (involuntary and striated, specific to the heart).

  • Ligaments: Dense connective tissues that connect bones to other bones at joints, providing stability and support. Ligaments are less flexible than tendons and have limited blood supply, which can hinder healing after injury.

  • Tendons: Connective tissues that attach muscles to bones, enabling the transfer of the force generated by muscle contraction to produce movement. They are composed of dense connective tissue and play a vital role in biomechanics.

  • Connective Tissues: Encompassing various forms such as cartilage (providing cushioning at joints and reducing friction during movement), fascia (surrounding muscles and helping organize muscle fibers), and synovial membranes (lining joint cavities and producing synovial fluid to lubricate joints).

• Skeletal Functions: The skeletal system serves multiple essential functions in the body:

  • Provides body structure: The skeleton not only gives the body its shape but also aids in the overall support and posture. It maintains the integrity of the body through its rigid framework.

  • Protects internal organs: The rib cage protects critical organs such as the heart and lungs, the skull safeguards the brain, and the vertebral column provides protection for the spinal cord.

  • Storage of minerals and fats: Bones serve as reservoirs for vital minerals, including calcium and phosphorus, which are essential for various metabolic processes. Yellow marrow in long bones stores fats, which can be used as an energy source.

  • Blood cell production: Bone marrow is the site of hematopoiesis, the process of producing red blood cells, white blood cells, and platelets, crucial for transporting oxygen, combating infections, and facilitating blood clotting, respectively.

• Muscle Functions: Muscle tissue performs critical roles, including:

  • Producing movement: Muscles contract in response to neural stimuli, enabling both voluntary actions (like walking) and involuntary actions (like the heartbeat).

  • Stabilizing joints: Muscles and their associated tendons work to stabilize joints during movement and maintain posture against the force of gravity.

  • Generating heat: Muscle activity generates heat through metabolic processes, contributing to thermoregulation and maintaining body temperature.

  • Maintaining posture: Continuous contraction of specific muscles allows the body to maintain posture and equilibrium, which is essential during static and dynamic activities.

• Bones and the Renal Connection:

  • Erythropoietin (a renal hormone) plays a significant role in stimulating the bone marrow to produce red blood cells (RBCs), particularly in response to hypoxia (low oxygen levels).

  • In patients with renal failure, the inability to produce erythropoietin leads to challenges in RBC synthesis, causing anemia and insufficient oxygen transport throughout the body, ultimately affecting overall health and stamina.

• Types of Connective Tissue:

  • Tendon: Connects muscle to bone; facilitates movement by transmitting forces generated by muscle contractions. Tendons can be subject to injuries like tendinitis, particularly in athletes and individuals performing repetitive motions.

  • Ligament: Connects bone to bone; critical for joint stability and support. Ligament injuries can result in sprains, causing pain and sometimes requiring surgical intervention.

  • Cartilage: A flexible tissue that encases the ends of bones at joints; provides smooth surfaces for joint movement while absorbing shock and reducing friction—crucial in load-bearing activities.

  • Fascia: A fibrous connective tissue that encloses muscles, nerves, and blood vessels, playing an essential role in muscle coordination and structural integrity.

• Specific Injuries: Common musculoskeletal injuries include:

  • Strain: An injury affecting muscles or tendons, often resulting from overstretching or excessive force. Symptoms include pain, swelling, muscle spasms, and limited mobility.

  • Sprain: An injury to a ligament caused by stretching or tearing, usually due to awkward movements or falls. Symptoms consist of pain, swelling, bruising, and impaired movement.NUR 363 Module 3 Study Guide:

      • Patient teaching activities and debriefing.

      • Practice Questions and mini-case studies.

    Common Medications Affecting Sensation and Perception (Table 27.2)

    • Antihistamines (e.g., loratadine, diphenhydramine):

      • Possible Side Effects: Blurred vision, dry mouth.

    • Antihypertensives (e.g., $\beta$ blockers, calcium channel blockers, ACE inhibitors):

      • Possible Side Effects: Blurred vision, alterations in taste and smell.

    • Miotic Eye Drops (e.g., pilocarpine, carbachol):

      • Possible Side Effects: Changes in vision, increase in nearsightedness, blurred vision.

    • Antiseizure Drugs (e.g., topiramate, acetazolamide):

      • Possible Side Effects: Numbness in hands and feet, dry mouth, tinnitus (ringing in ears), blurred vision, eye pain, metallic taste.

    • Diuretics (e.g., furosemide):

      • Possible Side Effects: Hearing loss, tinnitus, alterations in taste and smell.

    • Chemotherapeutic Drugs:

      • Possible Side Effects: Alterations in taste and smell, paresthesia.

    • Antibiotics:

      • Possible Side Effects: Alterations in taste and smell, ototoxicity.

    Sensory Perception: Cataracts

    • Pathophysiology:

      • A cataract is defined as an opacity of the lens that distorts the image projected onto the retina.

      • As an individual ages, the lens gradually loses water and increases in density.

      • Increased lens density leads to it becoming opaque.

      • While both eyes may have cataracts, the rate of progression in each eye is usually different.

      • Age-related cataracts are the most common type; most Americans will develop a cataract by age $75$.

    • Etiology and Risk Factors:

      • Can be present at birth or develop at any time.

      • Often age-related, caused by trauma, or caused by exposure.

      • Prolonged use of certain drugs, intraocular or systemic diseases, and smoking history increase risk.

      • Systemic diseases like Diabetes mellitus and hypertension significantly increase the risk for visual problems.

    • Health Promotion and Prevention:

      • Avoid heavy sun or UV light exposure.

      • Wear sunglasses and eye/head protection.

      • Stop smoking.

    • Management and Surgery:

      • Surgery is the only cure for cataracts.

      • Phacoemulsification: Sound waves break up the lens, pieces are suctioned out, but the capsule remains largely intact.

      • Preoperative Care: Clients must instill different types of eye drops prior to surgery.

      • Postoperative Vision: Final best vision may not be achieved for $4$ to $6$ weeks. Replacement lenses can correct distance, but reading glasses may still be necessary.

    • Postoperative Care and Teaching:

      • Medications to Avoid: The nurse must question orders for medications that affect blood clotting immediately after surgery, such as Acetylsalicylic acid (aspirin) or NSAIDs (Ibuprofen). These increase the risk of hemorrhage.

      • Medications Indicated: Antibiotics, steroids, and acetaminophen with oxycodone are commonly given.

      • Activity: Avoid lifting and protect eyes from light with dark sunglasses outdoors.

      • Signs to Report: Report any reduction in vision to the surgeon immediately.

      • Normal Findings: Mild itching and a bloodshot appearance are normal.

      • Abnormal Findings: Pain accompanied by nausea and vomiting (indicates increased intraocular pressure or hemorrhage); change in visual acuity with tearing/redness or yellowish drainage (indicates infection).

    Sensory Perception: Hearing Loss

    • Types of Hearing Loss:

      1. Conductive: Difficulty in the external ear or middle ear.

      2. Sensorineural: Difficulty in the inner ear or the acoustic nerve ($8^{th}$ cranial nerve).

      3. Mixed Conductive-Sensorineural: A combination of both types.

    • Clinical Concepts:

      • Presbycusis: Age-related hearing loss.

      • Tinnitus: Ringing in the ear(s). Diagnostic testing cannot confirm it but is used to rule out other disorders.

      • Mnière Disease: Characterized by episodic vertigo, tinnitus, and hearing loss. Usually occurs in adults between $20$ and $40$ years old.

    • Risk Factors for Hearing Loss:

      • Advanced age (normal aging changes).

      • Regular use of ototoxic drugs (e.g., furosemide).

      • Family history (genetic risk).

      • Chronic exposure to loud noises (e.g., sound managers, loud music).

      • Note: Hearing loss does not affect males more than females.

    • Nursing Care and Safety:

      • The priority intervention for hearing-impaired clients is creating a safe environment (clients may miss alarms).

      • Maximize communication: Sit in adequate light, face the client directly so they can visualize the nurse speaking, and provide written instructions.

      • Assessment: The external ear develops at the same time as the kidneys and urinary tract in the embryo. Any defect of the external ear demands an examination for problems in the urinary systems.

    • Hearing Aid Care Teaching:

      • Keep the hearing aid dry; do not wear while showering.

      • Check and replace batteries as needed.

      • Clean the hole of debris with a soft toothbrush.

      • Clean the ear mold with mild soap and water (avoid excessive wetness).

      • Adjust volume to the lowest setting that allows hearing without feedback.

    Sensory Perception: Glaucoma

    • Pathophysiology: Increased intraocular pressure (IOP).

    • Types: Open-angle, angle-closure, and secondary.

    • Incidence: Most common cause of blindness in North America, affecting $3$ million adults in the U.S.

    • High-Risk Groups: African-Americans over $40$, individuals over $60$ (especially Hispanic/Latino), and those with a family history.

    • Management:

      • Drug Therapy: Regular instillation of eye drops is critical.

      • Surgical Options: Laser trabeculoplasty, tube shunt surgery, cyclophotocoagulation, and laser peripheral iridotomy (LPI).

      • Transition Management: Follow-up every $1$ to $3$ months. Practice good handwashing and keep the tip of eye drop bottles clean.

    Chronic Injury to Brain: Neurodegenerative Disorders

    • Primary Focus: Alzheimer's Disease (Dementia).

    • Other Disorders: Parkinson's, Huntington's, Amyotrophic Lateral Sclerosis (ALS).

    • Alzheimer’s Pathophysiology and Vocabulary:

      • Anomia: The inability to find words.

      • Apraxia: The inability to use words or objects correctly.

      • Aphasia: The inability to speak or understand.

      • Agnosia: The loss of sensory comprehension.

    • Pharmacology:

      • Cholinesterase Inhibitors: Slow progression by improving cholinergic neurotransmission and delaying the destruction of acetylcholine (ACh) by acetylcholinesterase.

      • Antidepressants: SSRIs like paroxetine (Paxil) and sertraline (Zoloft) are prescribed for associated depression.

    • Nursing Management for Alzheimer's:

      • Maintain a consistent routine (clients function better).

      • Validation therapy.

      • Promote Independence: Allowing the client to choose an outfit from hangers supports independence while they can still perform ADLs.

      • Safety and Wandering: Enrollment in the "Safe Return" program and use of a medical ID bracelet. Avoid physical/chemical restraints (sedatives) unless as a last resort.

      • Home Safety: Ensure door locks can be easily opened (for emergency access) but monitor for wandering.

      • Behavioral: Clients may experience paranoia, delusions, or hallucinations. This is a byproduct of cognitive changes, not a psychiatric disorder.

    Acute Injury to Brain: Delirium, Seizures, and Stroke

    • Delirium: Acute onset; focus on causes, signs, symptoms, and active management.

    • Seizures and Status Epilepticus:

      • Status Epilepticus Management (Nursing Actions):

        • Maintain airway and ventilation: Indicated.

        • Place client in flat supine position: Contraindicated.

        • Establish IV and admin IV lorazepam or diazepam: Indicated.

        • Document type/duration of seizure: Indicated.

        • Monitor vitals (temp, HR, rhythm): Indicated.

        • Draw labs for serum electrolytes: Indicated.

        • Frequent LOC monitoring: Indicated.

    • Stroke Management:

      • BEFAST Pneumonic: Balance (Loss of), Eyes (Blurred vision), Face (Drooping), Arms (Weakness), Speech (Difficulty), Time (Call ambulance).

      • Hemisphere Differences:

        • Left Hemisphere Stroke: Right visual field deficits, intellectual impairment, inability to discriminate words and letters.

        • Right Hemisphere Stroke: Left visual field neglect, disorientation to time/place, constant smiling.

      • Priority Intervention: Elevate the head of the bed (HOB) to protect the airway and prevent swallowing concerns.

      • Fibrinolytic Therapy: Must meet strict criteria; usually administered within $3$ hours (up to $4.5$ hours) after the first symptoms of a stroke.

      • Aspiration Precautions: Do not provide fluids/food until a swallow screen (testing gag and cough reflex) is completed.

      • Safety: Maintain bed in low position. Call lights may be ineffective if the patient has field neglect.

    Injury to Spinal Cord

    • Priority Assessment: Always the Airway ($A$), followed by Circulation ($C$), Level of Consciousness ($LOC$), and Sensory Perception.

    • Complications:

      1. Neurogenic Shock:

         • Characterized by severe bradycardia (e.g., $HR = 50/min$), severe hypotension (e.g., $BP = 80/60$), and warm, dry skin.

         • Management: Notify provider immediately; restore fluids to circulating volume.

      2. Autonomic Dysreflexia:

         • Neurologic emergency occurring in clients with injury at $T6$ and above.

         • Symptoms: Sudden severe headache, flushing, extreme hypertension (e.g., $190/100$), bradycardia.

         • Priority Action: Place the client in a sitting position first.

         • Cause: Noxious stimulus, most commonly a distended bladder (urinary catheter obstruction) or fecal impaction.

      3. Spinal Shock: General loss of reflex activity below the level of injury.

    • Rehabilitation Care:

      • Focus on self-care, mobility skills, and bowel/bladder retraining.

      • Typical stay: $1$ to $2$ months.

    Questions and Discussion

    • Question (Cataract Progression): How will the nurse respond when a client asks why a cataract only happened in one eye?

      • Response: While cataracts may eventually affect both eyes, the rate of progression in each eye is usually different. It is an age-related density increase in the lens.

    • Question (Vision Loss Risk): Which client is at the greatest risk for developing vision loss?

      • Response: The client with diabetes mellitus. Systemic diseases like diabetes and hypertension have serious adverse effects on vision.

    • Question (Discharge Lighting): Priority intervention for discharge teaching for an older adult with vision problems?

      • Response: Ensure adequate, nonglare lighting is in the room. Changes in aging eyes alter vision and increase fall risks; lighting is the first priority for safety during teaching.

    • Question (Ear Deformity): If a nurse notices a deformity of a client’s right external ear, which assessment is the priority?

      • Response: Urinary tract function. The external ear and the kidneys develop simultaneously in the embryo.

    • Question (Alzheimer's Paranoia): How should a nurse respond to reports of paranoia in an Alzheimer's client?

      • Response: Paranoia, delusions, and hallucinations are known occurrences in dementia; it does not necessarily mean there is an underlying psychiatric condition, but rather a byproduct of cognitive changes.

    • Question (Spinal Cord Perfusion): What finding should be reported immediately during spinal cord observation?

      • Response: A blood pressure of $90/70$ or lower. Low systolic pressure can indicate decreased perfusion to the spinal cord, worsening the injury.

    • Transient Ischemic Attack (TIA)

      • Definition: A TIA is considered a "warning sign" of a potential future stroke. It involves transient focal neurologic dysfunction.

      • Pathophysiology: It is caused by a brief interruption in cerebral blood flow.

      • Etiology:

        • Cerebral vasospasm.

        • Systemic arterial hypertension.

      Stroke (Cerebral Vascular Accident / Brain Attack)

      • General Definition: A change in the normal blood supply to the brain, which often causes increased intracranial pressure (ICP).

      • Causative Agents:

        • Hypertension.

        • Arteriovenous malformation.

      • Major Types of Strokes:

        • Ischemic Stroke: These are caused by an obstruction within a blood vessel supplying blood to the brain.

          • Thrombotic Stroke: The process of clot formation (thrombosis) results in a narrowing of the lumen, which blocks the passage of blood through the artery.

          • Embolic Stroke: An embolus is a blood clot or other debris circulating in the blood. When it reaches an artery in the brain that is too narrow to pass through, it lodges there and blocks the flow of blood.

        • Hemorrhagic Stroke: A burst blood vessel allows blood to seep into and damage brain tissues until clotting shuts off the leak. A massive hypertensive hemorrhage can rupture into a lateral ventricle of the brain.

      • Risk Factors:

        • Modifiable: Smoking (all types, including cigars), substance use, obesity, sedentary lifestyle, oral contraceptive use, and use of phenylpropanolamine (PPA) found in antihistamine drugs.

        • Non-modifiable: Family history, race, and ethnicity.

      Stroke Assessment and Identification

      • Initial Priority: The first priority is to transport the patient to a certified stroke center.

      • Focused History:

        • When did the symptoms begin?

        • What was the patient doing at the time?

        • How did the symptoms progress?

        • Medical history, current medications, and social history.

      • Five Most Common Signs:

        1. Sudden confusion, trouble speaking, or understanding others.

        2. Sudden numbness or weakness of the face, arm, or leg.

        3. Sudden trouble seeing in one or both eyes.

        4. Sudden dizziness, trouble walking, or loss of balance/coordination.

        5. Sudden, severe headache with no known cause.

      • BEFAST / SOS Stroke Identification:

        • B - Balance: Loss of balance, headache.

        • E - Eyes: Blurred vision.

        • F - Face: One side of the face is drooping.

        • A - Arms: Arm or leg weakness.

        • S - Speech: Speech difficulty.

        • T - Time: Time to call for an ambulance immediately.

      • National Institute of Health Stroke Scale (NIHSS):

        • A valid and reliable assessment tool used to determine eligibility for IV fibrinolytic drugs.

        • Consists of $11$ areas of assessment.

        • Score ranges from $0$ to $40$.

      Neurologic and Physiological Manifestations of Stroke

      • Cognitive Changes: Denial, spatial/proprioceptive dysfunction, impaired judgment, memory issues, and problem-solving deficits.

      • Motor Changes: Hemiplegia (paralysis), hemiparesis (weakness), and ataxia (gait issues).

      • Sensory Changes: Unilateral inattention (body neglect) syndrome, ptosis, and nystagmus.

      • Cranial Nerve Assessment:

        • CN V: Ability to chew.

        • CN IX & X: Ability to swallow.

        • CN VII: Facial paralysis.

        • Dysphagia: Difficulty swallowing.

      • Cardiovascular Assessment: Heart murmur, dysrhythmias (specifically atrial fibrillation), and hypertension. Atrial fibrillation increases the risk for embolic stroke.

      • Lateralization of Brain Damage:

        • Right-brain Damage (Stroke on right side):

          • Paralyzed left side (hemiplegia).

          • Left-sided neglect.

          • Spatial-perceptual deficits.

          • Tendency to deny or minimize problems.

          • Rapid performance and short attention span.

          • Impulsive behavior and safety problems.

          • Impaired judgment and time concepts.

        • Left-brain Damage (Stroke on left side):

          • Paralyzed right side (hemiplegia).

          • Impaired speech/language (aphasias).

          • Impaired right/left discrimination.

          • Slow performance and cautious behavior.

          • Awareness of deficits leading to depression and anxiety.

          • Impaired comprehension related to language and math.

      Diagnostics and Thrombolytic Therapy

      • Laboratory Tests: There is no definitive lab test for stroke. Prothrombin time (PT/INR) and Partial Thromboplastin time (PTT) are used to establish a baseline before starting anticoagulation.

      • Imaging: Cat Scan (CT), Magnetic Resonance Imaging (MRI), and Carotid duplex scanning.

      • IV (Systemic) Thrombolytic Therapy:

        • Drug: rtPA (tissue plasminogen activator), specifically Alteplase, is the only approved drug to re-establish blood flow.

        • Eligibility: Based on a CT scan to confirm ischemic stroke and the time of symptom onset.

        • Timeframes: Must be given within $3$ hours of onset generally, or within $4.5$ hours with specific exceptions.

        • Priority of Care: Observe for signs of intracerebral hemorrhage (e.g., changes in mental status like drowsiness) and other signs of bleeding (epistaxis).

        • Lower patient to the ground/position in bed in lowest position.

        • Cushion head with a pillow and loosen tight clothing.

        • Turn to side-lying position to prevent aspiration and allow drainage of secretions.

        • Do Not restrain the patient or leave them unattended.

      Status Epilepticus

      • Definition: A seizure lasting greater than $5$ minutes or repeated seizures over a $30$-minute period.

      Dementia and Alzheimer’s Disease (AD)

      • Dementia: A syndrome characterized by cognitive dysfunction, loss of memory, and progressive loss of brain function. Older age is the most important risk factor.

      • Alzheimer’s Disease: The most common form of dementia. It is a chronic, progressive, and degenerative disease of the brain.

      • Early Warning Signs ($10$ Signs):

        1. Memory loss that affects job skills (going beyond forgetting a name).

        2. Difficulty performing familiar tasks (cooking a meal but forgetting to serve it).

        3. Problems with language (forgetting simple words or inappropriate substitutions).

        4. Disorientation to time and place (becoming lost on one’s own street).

        5. Poor or decreased judgment (wearing a bathrobe to the store).

        6. Problems with abstract thinking (difficulty with basic calculations).

        7. Misplacing things in inappropriate places (utensils in clothing drawers).

        8. Changes in mood or behavior (rapid swings for no reason).

        9. Changes in personality (becoming angry, suspicious, or fearful).

        10. Loss of initiative.

      • Progression and Late Stage Symptoms:

        • Intermediate: Dysphasia, Apraxia, Visual agnosia, Dysgraphia, wandering.

        • Late: Long-term memory loss, inability to communicate, inability to perform ADLs, incontinence, and unresponsiveness.

      • Diagnostic Tools: Mini-Mental State Examination (MMSE) helps document the degree of cognitive impairment and provides a baseline. PET scans can show hypometabolism in advanced AD brain. A brain biopsy is a definitive (though rarely clinical) diagnosis.

      • AD Drug Therapy:

        • Cholinesterase Inhibitors: Increase acetylcholine. Examples: Donepezil (Aricept), Rivastigmine (Exelon), Galantamine (Razadyne).

        • NMDA Receptor Antagonist: Memantine (Namenda).

        • Antidepressants: SSRIs (Fluoxetine, Sertraline, Citalopram). Tricyclic Antidepressants are used with caution due to confusion and constipation risks.

      AD Nursing Care and Behavioral Management

      • Priority: Providing a safe environment is the priority goal.

      • Routine: Maintain familiar routines for sleep, meals, and meds. Do not test orientation at every encounter if it causes agitation.

      • Behavioral Problems: Occur in $90\%$ of patients; includes repetitiveness, delusions, hallucinations, agitation, and aggression.

      • Sundowning: Agitation and confusion that worsens in the late afternoon/evening.

        • Interventions: Calm environment, maximize daylight exposure, limit caffeine/naps, and evaluate meds.

      • Communication Guidelines:

        • DO: Treat as adults, use gentle touch, direct eye contact, simplify tasks, and use distraction/redirection.

        • DO NOT: Criticize, argue, rush, or use condescending terms (e.g., "honey").

      • Nutrition in Middle/Late Stages:

        • Provide pureed food, thickened liquids, and finger foods to allow self-feeding.

        • Use easy-grip utensils and offer liquids frequently.

        • Short-term options: NG or PEG tube feedings.

      Delirium

      • Definition: A medical emergency that is often preventable and treatable. It is characterized by more confusion than normal.

      • Risk Factors (DELIRIUM mnemonic):

        • D: Dehydration

        • E: Eyes and ears (sensory deficits)

        • L: Limited mobility

        • I: Infection

        • R: Reduce pain

        • I: Impaired cognition

        • U: Up at night (sleep deprivation)

        • M: Medication

      • Identification: Single Question to identify Delirium (SQID): "Are they more confused than normal?" Use the 4AT rapid assessment test.

      • Management: Treat the cause, avoid transfers, reorient to place/time, adequate fluids, and use of eyeglasses/hearing aids.

      Questions & Discussion

      • Q: Which statement about preventing stroke indicates a need for further teaching?

        • A: "I only smoke cigars, which is better than smoking cigarettes." (Teaching: All types of smoking increase stroke risk).

      • Q: What finding is the highest priority for a patient on alteplase?

        • A: Client continues to be drowsy. (Indicates potential brain bleed/change in mental status).

      • Q: Priority action for acute ischemic stroke admission?

        • A: Keep NPO until swallowing assessment is complete.

      • Q: Nursing diagnosis for impaired memory intervention?

        • A: Maintain familiar routines of sleep, meals, and drugs. (Structure is very helpful; avoiding constant questioning reduces agitation).

      • Q: How is dementia defined?

        • A: A syndrome characterized by cognitive dysfunction and loss of memory.

      • Q: What is the clinical diagnosis of dementia based on?

        • A: Patient history and cognitive assessment. (Biopsy is definitive but usually post-mortem or rare; CT/MRI help rule out other things).

      • Definition: A TIA is considered a "warning sign" of a potential future stroke, serving as an important indicator of heightened stroke risk. It involves brief episodes of focal neurologic dysfunction that typically last less than 24 hours, most often just a few minutes to an hour. While symptoms may resolve quickly, the occurrence of a TIA markedly increases the likelihood of a subsequent stroke in the future.

      • Pathophysiology: The transient nature of a TIA is caused by a brief interruption in cerebral blood flow, often due to an embolism or a thrombus that obstructs arterial supply to a specific brain region. This disrupted blood flow leads to temporary neuronal dysfunction without resulting in permanent brain damage.

      • Etiology:

        • Cerebral Vasospasm: An acute narrowing of the cerebral arteries, often due to increased muscle tone or irritative factors affecting the blood vessels.

        • Systemic Arterial Hypertension: Chronic high blood pressure can damage blood vessels, increasing the risk of embolism and clot formation that may lead to TIAs.

        • Cardiac Factors: Atrial fibrillation and other arrhythmias can result in the formation of clots in the heart that can lead to obstruction of cerebral arteries.

        • Atherosclerosis: Buildup of fatty deposits and other substances within arterial walls can restrict blood flow and contribute to TIAs.

      • Symptoms: Symptoms are similar to those of a stroke but are temporary and resolve quickly. They can include:

        • Sudden weakness or numbness on one side of the body, particularly in the face or limbs.

        • Sudden confusion or difficulty speaking, understanding speech, or finding the right words.

        • Sudden visual disturbances in one or both eyes.

        • Dizziness, loss of balance, or difficulty walking.

        • A sudden severe headache with no known cause.

      • Diagnosis: Diagnosis is primarily clinical based on symptoms and patient history, but imaging studies like CT or MRI can be employed to rule out other causes or confirm ischemia. Additionally, carotid ultrasound may be used to assess for potential vascular blockages.

      • Management and Prevention: Management focuses on preventing subsequent strokes, emphasizing:

        • Lifestyle Modifications: Encouraging healthy eating, regular exercise, smoking cessation, and weight management.

        • Medications: Anti-platelet agents (e.g., aspirin, clopidogrel) and anticoagulants for patients with specific cardiac abnormalities. Statins and antihypertensive medications may also be prescribed to manage underlying conditions.

        • Monitoring and Risk Assessment: Regular follow-up to evaluate risk factors and implement further preventive strategies as needed.

        • Patient Education: Informing patients about warning signs of impending stroke and the critical importance of immediate medical attention if symptoms occur again, even if transient.

        • Referral to neurology for high-risk patients may be considered to assess for further preventive interventions, including possible surgical options to address significant carotid artery stenosis.
