A 42-year-old woman is brought to the emergency department due to profound weakness, vomiting, and confusion. She has a history of systemic lupus erythematosus and has taken daily oral prednisone for the past 5 years. However, she ran out of her medication one week ago. Two days ago, she developed nausea, vomiting, and diarrhea. Her temperature is 37.8°C (100°F), heart rate is 125/min, respiratory rate is 22/min, and blood pressure is 70/40 mmHg. Physical examination reveals a lethargic and diaphoretic patient. Laboratory results show:
| Test | Result |
|---|---|
| Sodium | 128 mEq/L |
| Potassium | 5.8 mEq/L |
| Glucose | 55 mg/dL |
Which of the following are the most appropriate immediate stabilization steps for this patient? (Select 2)
- Rapid intravenous administration of isotonic fluids containing dextroseCevap
- Intravenous administration of high-dose hydrocortisoneCevap
- CPerformance of a cosyntropin (adrenocorticotropic hormone) stimulation test
- DComputed tomography scan of the abdomen and pelvis
- EImmediate admission to the general medical ward
Cevap
The correct immediate stabilization steps are the rapid intravenous administration of isotonic fluids containing dextrose and the intravenous administration of high-dose hydrocortisone.
The patient is in an acute adrenal crisis, triggered by abrupt cessation of chronic exogenous glucocorticoids and the physiological stress of a gastrointestinal illness. This is a life-threatening emergency presenting with distributive shock, hypoglycemia, hyponatremia, and hyperkalemia. Immediate stabilization requires reversing the volume depletion and hypoglycemia with intravenous isotonic fluids containing dextrose, alongside the simultaneous administration of high-dose intravenous glucocorticoids (such as hydrocortisone) to restore vascular tone and correct the hormonal deficit.
Adım Adım Çözüm
Anahtar Kavram
In a patient presenting with acute adrenal crisis (distributive shock, hypoglycemia, and electrolyte derangements following cessation of chronic steroids), immediate stabilization requires volume resuscitation with dextrose-containing isotonic fluids and immediate glucocorticoid replacement prior to any diagnostic testing.
