Final review for LS

Symptoms and Pathophysiology of Multiple Sclerosis (MS)

  • Overview of MS

    • MS is an autoimmune disease where the immune system attacks the myelin sheath surrounding nerve fibers.

    • Myelin Sheath: A protective covering that aids in the efficient transmission of electrical impulses between the brain and the body.

  • Symptoms

    • Muscle Symptoms:

    • Stasis

    • Muscle spasticity

    • Dysmetria or Ataxia: This refers to the loss of coordination of movements, affecting walking, balance, and limb movement.

    • Tremors: Can occur alongside spasticity.

    • Neurological Symptoms:

    • Nystagmus: Involuntary eye movement that may impact vision.

    • Difficulty in chewing and swallowing.

    • Paresthesia: Abnormal sensations such as tingling or numbness, typically bilateral (affecting both sides).

    • Changes in sensation can also begin in the extremities and may progress to the trunk.

    • Urinary Issues: Urinary retention necessitating interventions such as using a straight catheter.

  • Distinct Characteristics:

    • Symptoms are usually bilateral in MS, contrasting with strokes, which generally present unilaterally.

Diagnosis of Multiple Sclerosis (MS)

  • Diagnostic Approach:

    • There is no single definitive test for MS. Diagnosis is based on a combination of:

    • Clinical presentation and reported symptoms.

    • Assessment findings through medical history and physical examinations.

    • Imaging tests such as CT scans or MRIs to visualize lesions in the central nervous system related to MS.

    • Genetic Testing: Not typically used, but a family history may indicate increased risk for developing MS.

Interventions and Treatment for MS

  • Priority Problems:

    • Fatigue management, including work/rest periods and activity prioritization.

    • Modifications to activities of daily living (ADLs) as needed.

    • Avoidance of extreme temperatures, overexertion, and stress to mitigate exacerbations.

  • Preventive Strategies:

    • Infection prevention, especially in the context of immunosuppressive therapies.

Acute Spinal Cord Injury Response

  • Initial Management:

    • Immediate mobilization and immobilization of the spine, especially cervical regions, to prevent secondary injury to the spinal cord if it’s intact but at risk.

    • Establishing an Airway, Breathing, Circulation (ABCs) prioritization for post-injury patients.

    • Monitoring blood pressure to avoid complications like Autonomic Dysreflexia (AD) or neurogenic shock, which can cause severe hypotension immediately after injury.

Overview of Psychiatric Conditions: Schizophrenia and Bipolar Disorder

  • Schizophrenia:

    • Symptoms: Positive symptoms (delusions, hallucinations) pose significant safety concerns.

    • Communication: Building rapport and using therapeutic communication techniques are essential.

    • Monitoring for complications due to poor self-care (nutrition, hygiene) during psychotic episodes.

  • Bipolar Disorder:

    • Phases: Mania, hypomania, depression.

    • Safety is a prime concern due to risks of self-harm or impulsivity in manic states and hopelessness in depressed states.

    • Important to address medication adherence and optimize nutrition to prevent further health decline.

Kidney Disease Overview

  • Lab Values:

    • Elevated creatinine and blood urea nitrogen (BUN); decreased urine output.

    • Electrolyte abnormalities include high potassium, elevated phosphorus, and low calcium.

  • Dietary Considerations:

    • Generally low sodium and protein diets, with hydration dependent on stage of kidney disease.

Stroke Comprehension

  • Recognizing Signs and Symptoms:

    • Watch for unilateral weakness, sensory changes, compromised mobility, and impaired swallowing.

    • Post-stroke interventions include safety assessments, and adaptations in ADLs as needed.

Pulmonary Embolism (PE) Treatment Protocol

  • Inpatient Management:

    • Initiate treatment with anticoagulation (heparin) and transition to oral anticoagulants (warfarin) post-discharge.

    • Long-term monitoring of coagulation parameters like Prothrombin Time (PT) to ensure efficacy and safety in anticoagulation therapy.

Cystic Fibrosis Pathophysiology

  • Genetic Basis:

    • Caused by mutations in the CFTR gene affecting chloride transport, resulting in thick mucus production primarily impacting the lungs leading to chronic infections.

  • Important Interventions:

    • Medication: Use of bronchodilators and mucolytics to aid in mucus clearance.

    • Physiotherapy: Chest physiotherapy, including percussion, to mobilize secretions.

Leukemia Pathophysiology

  • Key Features:

    • Presentation of high faulty white blood cells, low platelets (thrombocytopenia), and anemia.

    • Symptoms: Pallor, fatigue, susceptibility to infections, joint pain, and potential bleeding complications.

  • Treatment Approaches:

    • Primarily through chemotherapy and supportive care targeting symptom management (nutrition, infection prevention).

Sickle Cell Disease Overview

  • Pathophysiology:

    • Abnormal hemoglobin (hemoglobin S) leads to deformed erythrocytes causing vaso-occlusive crises and impaired perfusion.

  • Crisis Triggers:

    • Dehydration, high altitudes, infection, emotional stress.

  • Management:

    • Key interventions include ensuring hydration, pain control, oxygen therapy, and disease-modifying medications (e.g. hydroxyurea).

Rheumatoid Arthritis and Lupus Comparison

  • Demographics:

    • Predominantly affects females, with variations in risk factors and symptoms for RA and lupus.

  • Patient Education and Interventions:

    • Focus on stress reduction, sun protection (specific to lupus), and managing comorbid conditions.

  • Risk of Infection:

    • Both conditions may present risks associated with immunosuppressive therapies in treatment regimens.
