In hypokalemia, which pattern is typical?

• A. Everything high except heart rate and urinary output, which are low.
• B. Everything low except heart rate and urinary output, which are high.
• C. Everything low, including heart rate and urinary output.
• D. Everything high, including heart rate and urinary output.

Answer: (B)

In hypokalemia, the body is in a state of electrolyte and often volume depletion, so potassium is low while compensatory mechanisms push the heart rate up and urine production can be high. When potassium is lost, especially with diuretic use or renal/GI losses, you tend to see low levels of multiple electrolytes overall. The heart responds to reduced circulating volume and electrolyte disturbances with tachycardia, and ongoing diuresis or renal losses keep urine output elevated. That combination—most things down, but heart rate and urine output up—fits the typical pattern seen in hypokalemia scenarios.
