Which sign is NOT typically seen with hyperkalemia due to hypoaldosteronism after adrenalectomy?

• A. Muscle weakness
• B. Tremors
• C. Diaphoresis
• D. Nausea

Answer: (C)

Hyperkalemia after adrenalectomy results from hypoaldosteronism, which reduces potassium excretion by the kidneys. The easiest way this presents is with signs caused by high potassium affecting neuromuscular function and the gut: muscle weakness and fatigue, and nausea from electrolyte disturbance. Tremors aren’t a classic feature of hyperkalemia, and sweating (diaphoresis) isn’t caused by elevated potassium levels. Diaphoresis is more associated with autonomic arousal, pain, anxiety, or other conditions, not the typical manifestations of hyperkalemia. So, the sign that wouldn’t be expected with this condition is diaphoresis. If hyperkalemia is suspected, monitor for characteristic ECG changes and treat promptly to protect cardiac conduction.
