Before administering Digoxin, which assessment is essential?

• A. Check blood pressure
• B. Check apical pulse for one minute and hold if pulse is <60
• C. Check respiratory rate
• D. Check serum potassium only

Answer: (B)

Assessing the apical pulse for a full minute and holding the dose if it’s less than 60 beats per minute is essential because digoxin can slow the heart’s conduction, especially through the AV node, leading to bradycardia or heart block. The apical pulse provides the most accurate measurement of the heart rate for patients on digoxin, and a low rate means the drug could be unsafe to administer at that moment. Digoxin carries a narrow therapeutic window, so preventing bradycardia is a key safety step. While blood pressure, respiratory rate, and potassium status matter in overall patient care, they don’t directly determine whether it’s safe to give digoxin at that moment. Potassium level is important because hypokalemia increases the risk of digoxin toxicity, but you still wouldn’t administer digoxin without confirming the heart rate first.
