Endocrine, Family Medicine Board Certification Examination - Full Vignette with Extended Explanation

A 31-year-old woman with a complex medical history, including Sheehan syndrome after postpartum hemorrhage and prior cardiac and neurologic events, presents with acute lethargy, vomiting, severe fatigue, and unstable vital signs after missing her morning medications. What factors should be considered when rapidly assessing and prioritizing care for a visibly unstable patient with a background of multiple prior investigations and endocrine disease? How does her presentation guide urgent management decisions?

QUESTION A 31-year-old woman with a history of Sheehan syndrome after a postpartum hemorrhage, prior aortic dissection repair, Bell s palsy, and treated gonorrhea presents with acute lethargy and vomiting. She has taken no morning medications. On arrival, she is pale, cool, and confused. Staff cannot obtain a reliable noninvasive blood pressure reading. Pulse is 118/min, temperature 36.7 degreesC, respiratory rate 11/min, and oxygen saturation 98% on room air.... OPTIONS A. Give hydrocortisone 100 mg IV now, then 50 mg IV every 6 hours with isotonic fluids, before any labs or imaging. B. Order an ACTH stimulation test first and delay stress-dose steroids until the result is available. C. Give an IV levothyroxine 200 mcg bolus now to treat hypotension and fatigue in suspected pituitary disease during this collapse. D. Start a high-dose insulin infusion now for possible diabetic ketoacidosis before checking a bedside capillary glucose measurement. CORRECT ANSWER A. Give hydrocortisone 100 mg IV now, then 50 mg IV every 6 hours with isotonic fluids, before any labs or imaging. EXPLANATION This unstable patient with prior Sheehan syndrome (panhypopituitarism risk) has acute hypotensive collapse with lethargy, vomiting, and salt craving-classic for adrenal crisis. Immediate hydrocortisone 100 mg IV, then 50 mg IV every 6 hours with aggressive isotonic fluids, should be given before labs or imaging. In secondary adrenal insufficiency due to pituitary injury, hydrocortisone provides both glucocorticoid effect and some mineralocorticoid activity in crisis doses, and treatment must not be delayed. An ACTH stimulation test should never precede life-saving stress-dose steroids. Thyroid hormone before glucocorticoids can precipitate cardiovascular collapse by increasing cortisol clearance and metabolic demand. High-dose insulin has no role without confirmed hyperglycemia or ketoacidosis and risks worsening hypotension and hypoglycemia. In summary, the correct answer is immediate stress-dose hydrocortisone and fluids prior to diagnostic testing. Primary teaching point: Treat suspected adrenal crisis empirically with hydrocortisone 100 mg IV and fluids-do not delay for testing. Secondary teaching point: In secondary adrenal insufficiency (e.g., Sheehan syndrome), stress-dose hydrocortisone suffices acutely; add mineralocorticoid only if primary AI is confirmed later.
