In a client with heart failure receiving digoxin (Lanoxin) and furosemide (Lasix), which laboratory value requires immediate intervention?

  • A. Serum potassium of 4.0 mEq/L
  • B. Blood glucose of 200 mg/dl
  • C. Serum creatinine of 1.5 mg/dl
  • D. Serum potassium of 3.2 mEq/L
Correct Answer: D

Rationale: A serum potassium level of 3.2 mEq/L is low and concerning in a client receiving digoxin and furosemide. Hypokalemia increases the risk of digoxin toxicity, leading to life-threatening arrhythmias. Therefore, immediate intervention is necessary to prevent complications. The other options, serum potassium of 4.0 mEq/L, blood glucose of 200 mg/dl, and serum creatinine of 1.5 mg/dl, are within normal limits and do not pose immediate risks to the client in this scenario.
