🎯 HIGH-YIELD TOPICS (Most Questions)

ENDOCRINE SYSTEM (25 Questions - 50% of Exam)

HYPOTHYROIDISM (6 Questions) - HIGHEST YIELD

"Everything SLOWS DOWN"

Key Concept: Low thyroid hormone → ↓ metabolism → body functions decelerate

Clinical Manifestations (Memory: "COLD SLOW")

• Cold intolerance (key symptom from Jeopardy)
• Obesity/weight gain
• Lethargy (increasing - red flag for myxedema coma)
• Depression, constipation
• Slow reflexes, bradycardia
• Large tongue, facial puffiness
• Other: hair loss, dry skin, hoarse voice
• Weak, fatigue

Myxedema Coma (Critical Complication)

DEFINITION: Life-threatening emergency from severe, untreated hypothyroidism causing profound metabolic depression

Recognition Signs:

• Increasing lethargy (progressive drowsiness → stupor → coma)
• Cold intolerance with hypothermia (<95°F)
• Bradycardia (heart rate <60)
• Hypotension
• Hypoventilation (shallow, slow breathing)
• Altered mental status (confusion → coma)

Treatment: IV levothyroxine (from Jeopardy - note IV route, NOT oral!) Nursing Priorities:

• Monitor for cardiac arrhythmias, respiratory depression
• Passive rewarming (avoid rapid warming)
• Mechanical ventilation may be needed

Pregnancy Complications

Key Point: Hypothyroidism in pregnancy → preeclampsia risk Nursing: Monitor BP, proteinuria, fetal well-being

Diagnostic Workup

• Labs: ↑TSH, ↓T4, ↓T3
• Thyroid nodules: Fine needle biopsy to rule out malignancy (molecular testing)

---

• Hypertension then cardiovascular collapse
• Altered mental status (agitation → delirium → coma)
• GI symptoms: Nausea, vomiting, diarrhea
• Diaphoresis (profuse sweating)

Triggers: Stress, infection, trauma, surgery, stopping antithyroid meds

Treatment Protocol (Must know order!)

1. Anti-thyroid drugs (methimazole, PTU) - blocks hormone synthesis

Diabetic Retinopathy (Visual Complication)

DEFINITION: Diabetes-related damage to blood vessels in the retina, leading to vision problems and potential blindness

Pathophysiology:

• Duration of diabetes
• High blood pressure
• High cholesterol

Prevention:

• Tight glycemic control (HbA1c <7%)

Etiology: Elevated androgen levels in peripheral tissues Pathophysiology: Androgens → insulin resistance → hyperglycemia Connection: Contributes to hyperglycemia through impaired glucose metabolism Clinical: Irregular periods, hirsutism, acne, weight gain, insulin resistance

Stress Response Hyperglycemia

DEFINITION: Elevated blood glucose in response to physiological stress, occurring even in non-diabetic individuals

Pathophysiology:

• ↑Cortisol (stress hormone) → increased glucose production by liver
• ↑Catecholamines (epinephrine, norepinephrine) → decreased insulin sensitivity
• Result: Hyperglycemia from both increased glucose production and decreased utilization

Key Point: Can occur even without diabetes diagnosis Clinical Context: Surgery, trauma, infection, emotional stress

---

HEMATOLOGY SYSTEM (8 Questions - 16% of Exam)

DVT (Deep Vein Thrombosis) - 3 Questions

2. Hypercoagulability (increased clotting tendency): Cancer (non-small cell lung cancer produces procoagulant factors), pregnancy, medications
3. Endothelial injury (vessel wall damage): Trauma, procedures, IV lines

Diagnostics

D-Dimer: Elevated suggests PE (pulmonary embolism)

• Definition: Protein fragment from blood clot breakdown
• High sensitivity, low specificity
