Alterations in Tissue Integrity

Pressure Injuries (Decubitus Ulcers)

Definition

Pressure injuries are characterized by skin and/or tissue breakdown resulting from prolonged unrelieved pressure, which leads to ischemia (decreased blood flow).

Contributing Factors
  • Shear: Occurs when skin remains stationary against a surface while deeper tissues move, causing damage.
  • Friction: The skin is rubbed or dragged across a surface, leading to injury.
  • Excess Moisture: Increases vulnerability to skin breakdown.
  • Poor Nutrition: Malnutrition escalates risk of tissue injury.
Risk Factors
  • Age (elderly)
  • Fragile skin
  • Decreased mobility
  • Urinary or fecal incontinence
  • Nutritional deficits
  • Spinal cord injuries
Staging Pressure Injuries
  1. Stage 1: Intact skin with non-blanchable erythema. May be painful.
  2. Stage 2: Partial thickness loss with a pink/red moist wound bed; may present with blisters or shallow ulcers.
  3. Stage 3: Full thickness loss of skin with visible subcutaneous tissue; may present with undermining or tunneling.
  4. Stage 4: Full thickness loss with visible fascia, muscle, tendon, ligaments, or bone; often presents with undermining or tunneling.
  5. Unstageable: Full thickness loss where the extent cannot be seen due to slough or eschar.
  6. Deep Tissue Injury: May have intact/non-intact skin with persistent non-blanchable deep red, maroon, or purple discoloration.
Nursing Management
  • Assessment: Assess risk for tissue injury using the Braden Scale.
  • Prevention: The best strategy to manage pressure injuries, include positioning every 2 hours, off-loading, and using pressure relief devices.
  • Documentation: Note size (width, depth, length) of any developed pressure injuries and manage patient pain.
  • Treatment Methods:
      - Elevate heels, and control moisture (keeping skin clean using barrier creams, breathable incontinence pads).
      - Nutrition focus, especially on protein intake.

Alterations in Mobility

Musculoskeletal Anatomy and Physiology Overview

Components of the Musculoskeletal System
  • Bones: Provide structure, support, and protection for organs.
  • Joints: Allow for movement between bones (Shoulder Joint).
  • Ligaments: Connect bone to bone and stabilize joints.
  • Tendons: Connect muscles to bones.
  • Cartilage: Provides cushioning at joints.
  • Muscles: Allow for movement through contraction.

Assessment of the Musculoskeletal System

Subjective Data
  • Past Health History:
      - Previous trauma (sports injuries, fractures, sprains).
      - Conditions affecting connective tissue (arthritis, osteoporosis, tendinitis).
      - Autoimmune disorders (Rheumatoid arthritis, Lupus).
Common Medications for Musculoskeletal Conditions
  • Over-the-counter medications, such as NSAIDs and acetaminophen.
  • Skeletal muscle relaxants and corticosteroids (systemic/topical).
  • Opioids for severe pain management.
Additional Treatments for Musculoskeletal Conditions
  • Immobilization (braces, splints).
  • Physical therapy.
  • Surgical interventions (joint replacement surgeries).

Common Signs and Symptoms of Musculoskeletal Problems

  • Pain (in muscles, joints, bones), stiffness, swelling, bruising, warmth, decreased range of motion (ROM), and crepitus (popping, grinding sounds).
Importance of Nutrition
  • Adequate intake of vitamin C, vitamin D, calcium, and protein is critical for musculoskeletal health.
  • Obesity places stress on weight-bearing joints.

Diagnostics for the Musculoskeletal System

Imaging Procedures
  • X-Ray: Evaluates soft tissues, identifies bony abnormalities.
      - Note: Clients with iodine/shellfish allergies must be assessed.
  • CT Scan: Visualizes soft tissue; patient should be advised of the loud noises and metal restrictions.
  • MRI: Assesses soft tissue and requires the patient to remain still during the procedure.
Bone Scan and Arthroscopy
  • Bone Scan: Involves a radioisotope administered to detect fractures, cancer, or osteomyelitis.
  • Arthroscopy: A minimally invasive procedure that visualizes the interior of a joint for diagnosis or repair.

Osteoporosis

Definition

Osteoporosis is described as a chronic metabolic bone disorder that results in low bone density. This condition increases the risk of fractures, especially with minimal to no trauma (notable sites include wrist, hips, and spine).

Clinical Manifestations

Typically asymptomatic until a fracture occurs, but may include reduced height, acute back pain after lifting/bending, restriction of movement, thoracic kyphosis, and localized pain upon palpation.

Risk Factors
  • Age: >50 years.
  • Female, particularly post-menopausal (low estrogen).
  • Ethnicity: Higher incidence in Asian American, White American groups.
  • Hereditary factors: Thin, lean body builds.
  • History of nutritional inadequacies (calcium, vitamin D).
  • Lifestyle factors: Limited physical activity, excessive alcohol, or tobacco use.
  • Medical history: Malabsorption disorders or surgical history affecting nutrient absorption.
Diagnostic Testing
  • DEXA Scan (Dual-energy X-ray Absorptiometry): A non-invasive test to assess bone density, often evaluating hips and spine for osteopenia and osteoporosis.
Nursing Care and Client Education
  • Emphasize dietary intake of calcium and vitamin D.
  • Suggest sunlight exposure with sunscreen for natural vitamin D synthesis.
  • Advocate low weight-bearing exercises 30 minutes a day, 3-5 times weekly to enhance bone strength.
  • Assess home environments for fall risk and safety.
Medications for Osteoporosis
  • Calcitonin: Hormonal treatment.
  • Selective Estrogen Receptor Modulators: Raloxifene.
  • Calcium Supplements: Calcium carbonate and calcium citrate.
  • Vitamin D Supplements.
  • Bisphosphonates: Alendronate for decreasing fracture risk.

Soft Tissue Injuries

Definitions
  • Sprain: Injury to ligaments caused by wrenching or twisting motions.
  • Strain: Tears or excessive stretching of muscles, commonly in the lower back, calves, and hamstrings.
Clinical Manifestations

Common presentations include pain, edema, decreased function, and bruising (ecchymosis).

Nursing Management for Acute Injuries

RICE Protocol:

  • Rest: Limit movement to prevent further injury.
  • Ice: Apply ice (cryotherapy) for 10-20 minutes to reduce swelling and inflammation.
  • Compress: Use wraps to reduce swelling and pain, wrapping from distal to proximal.
  • Elevate: Keep injured area elevated above heart level.

Fractures

Definition

A fracture is a break in the continuity of a bone, which can arise from either traumatic injury or pathological processes (i.e., cancer, osteoporosis).
Fractures can be classified into two main categories:

  • Open Fractures: The skin is broken, exposing the bone.
  • Closed Fractures: The skin remains intact.
Types of Fractures by Completeness
  • Complete Fracture: Break occurs fully through the bone.
  • Incomplete Fracture: Partial break through the bone shaft, maintaining some bone integrity.
Displacement of Fractures
  • Displaced: Ends of the broken bone are misaligned.
  • Nondisplaced: Bone fragments remain in alignment.
Types of Bone Fractures
  1. Transverse: Fracture line extends straight across the bone shaft.
  2. Spiral: Fracture line spirals around the bone shaft.
  3. Greenstick: Incomplete fracture; one side splintered while other is bent.
  4. Comminuted: More than two fragments of the bone.
  5. Oblique: Lines of the fracture extend diagonally across the bone.
  6. Impacted: Part of the bone is pushed into another bone, shortening the length.
  7. Avulsed: A piece of bone attached to tendon or ligament pulls away from bone.
  8. Torus: The cortex buckles without breaking completely.
  9. Pathologic: An unexpected fracture occurring at site of diseased bone.
  10. Stress Fracture: Occurs in normal or abnormal bone under repetitive stress.

Clinical Manifestations of Fractures

  • Pain and tenderness at the trauma site, which leads to splinting behaviors to decrease mobility.
  • Edema and swelling within the affected area.
  • Muscle spasm due to pulling forces on the misaligned bones.
  • Possible deformity with visible bone in open fractures, shortening of the extremity, and asymmetrical appearance.
  • Bruising (ecchymosis) from underlying blood leakage and skin color changes.
  • Loss of function and ability to ambulate without assistance.
Nursing Management
Neurovascular Assessment
  • Monitor for signs of nerve damage and vascular integrity (skin color, temperature, capillary refill, peripheral pulses).
  • Document and assess pain, sensation, and motor function.
Weight-Bearing Status

Different criteria for weight bearing according to the status of the fracture involvement:

  • Non-Weight Bearing: No weight on the affected extremity.
  • Touch-Down/Toe-Touch Bearing: Up to 50% weight on the affected limb.
  • Partial Weight Bearing: Varies based on the patient's pain tolerance.
  • Weight Bearing as Tolerated: No restrictions on weight.
  • Full Weight Bearing: No limitations in motion.

Goals of Treatment

  1. Anatomically realign bone fragments (Reduction).
      - Closed Reduction: Manual manual manipulation without surgery.
      - Open Reduction: Surgical intervention where the fracture is realigned using pins, rods, or plates.
  2. Immobilization must be carried out after realignment to facilitate healing.
       - Treatment aims to restore nearly normal function of the injured site.
Types of Immobilization Methods

  • Casts: Protect and immobilize the injured bone.
      - Avoid moisture, elevate, and manage itching without inserting objects into the cast.
      - Report any signs of complications, notably worsening pain or discoloration around cast edges.

  • Traction: Application of a pulling force to keep bones aligned.
      - Skin Traction: Non-invasive, short term for aligning bones.
      - Skeletal Traction: Invasive, long-term alignment for significant fractures.

  • External Fixation: Devices employ pins and rods outside the body to stabilize and immobilize bones.

  • Internal Fixation: Plates/pins used surgically to maintain position of bone fragments.

Specific Fracture Types
Colles Fracture
  • Distal radius fracture, common in older adults. Risk of osteoporosis significantly contributes.
  • Managed via closed reduction and immobilization procedures.
Pelvic Fracture
  • Can range in severity and poses significant risks, such as internal injuries. Fractures in this area are associated with high mortality.

Complications of Fractures

Infection
  • High occurrence in open fractures necessitating prompt treatment. Antibiotics may be administered prophylactically.
Compartment Syndrome
  • Increased swelling and pressure in muscle compartments, constitutes a medical emergency.
  • Symptoms include the six P’s: Pressure, Pain, Paresthesia, Pallor, Paralysis, and Pulselessness.
  • Management: Regular neurovascular assessments and interventions may require fasciotomy to relieve pressure.
Venous Thromboembolism
  • Contributes to elevated risks in immobility cases, managed with anti-coagulants and establishing mobility protocols.
Fat Embolism Syndrome
  • Fat droplets enter vascular system post-fracture, causing ischemic occurs in vital organs. Symptoms develop within 24-48 hours post-injury.

  

Amputation

Causes
  • Approximately 50% of amputations arise from peripheral vascular disease (PVD) and diabetes, with trauma as a significant secondary cause.
Nursing Interventions
  • Stress daily inspection of lower extremities for complications.
  • Provide rehabilitation focus on upper extremity movements vital for crutch usage.
  • Prevent flexion contractures, particularly hip flexion, through positional strategies.

Case Studies and Clinical Application

  • Knee Arthroplasty: Involves postoperative care, including neurovascular checks and mobility encouragement with the assistance of appropriate equipment.
  • Fractured Femur: Requires evaluations for pain management, weight-bearing protocols, and monitoring for complications during recovery.

The transcript of case studies holds essential teaching implications for real-world applications within nursing and rehabilitative practices, underscoring the importance of thorough clinical assessments and patient-centered care.
