Pharmacological and Parenteral TherapiesQuestion 1308 of 2368

An infant who takes digoxin and furosemide is at risk for digoxin toxicity. Which laboratory finding increases this risk?

  1. Hypernatremia
  2. Hypokalemia
  3. Hyperglycemia
  4. Low hematocrit
Show answer

Correct answer: Hypokalemia

Low potassium or magnesium lowers the threshold for digoxin toxicity, and diuretics can deplete these electrolytes.
