The nurse is assessing a client who has a prescription for digoxin (Lanoxin). Which finding indicates that the client is at risk for digoxin toxicity?

  • A. Heart rate of 60 beats per minute
  • B. Blood pressure of 120/80 mm Hg
  • C. Respiratory rate of 18 breaths per minute
  • D. Serum potassium level of 3.0 mEq/L
Correct Answer: D

Rationale: A low serum potassium level increases the risk of digoxin toxicity. Digoxin toxicity is more likely to occur in individuals with low potassium levels because potassium is crucial for proper heart function. A heart rate of 60 beats per minute, blood pressure of 120/80 mm Hg, and respiratory rate of 18 breaths per minute are within normal ranges and do not directly indicate an increased risk of digoxin toxicity.
