Correct answer: D — Use sick-day glucocorticoid dosing throughout the febrile illness
The best answer is “Use sick-day glucocorticoid dosing throughout the febrile illness”. Intercurrent significant physiological stress requires additional glucocorticoid according to the patient’s sick-day plan even when tablets can be retained. The emergency injection is used when oral medicine cannot be absorbed or severe deterioration occurs. Fludrocortisone does not replace cortisol stress cover, and omitting or leaving glucocorticoid unchanged risks adrenal crisis.
