Which lab value should be monitored most closely to avoid to xicity? A. Serum potassium B. Serum magnesium C. Serum creatinine D. Serum albumin Correct Answer: A. Serum potassium Rationale: Hypokalemia increases the risk of digoxin toxicity by enhancing digoxin binding to myocardial tissue. Potassium levels must be closely monitored in heart failure patients on digoxin. 2. A patient is receiving heparin therapy. Which finding would require immediate intervention? A. Platelet count of 180,000/mm³ B. Activated partial thromboplastin time (aPTT) 1.5 times baseline C. Hematuria D. Mild bruising at injection site Correct Answer: C.
