A healthcare provider in a clinic is monitoring serum electrolytes for four older adult clients who take digoxin. Which of the following electrolyte values increases a client's risk for Digoxin toxicity?

  • A. Calcium 9.2 mg/dL
  • B. Calcium 10.3 mg/dL
  • C. Potassium 3.4 mEq/L
  • D. Potassium 4.8 mEq/L
Correct Answer: C

Rationale: Potassium 3.4 mEq/L is below the expected reference range, which increases the risk for digoxin toxicity. Low potassium levels can lead to fatal dysrhythmias, particularly in older clients taking Digoxin. Monitoring and correcting electrolyte imbalances are crucial to prevent adverse effects of digoxin therapy.
