Before administering digoxin, the nurse counts an adult patient's apical pulse at 54 beats per minute. What is the most appropriate action?
Correct answer: B. Withhold the dose and notify the prescriber
- A. Give the dose because digoxin raises the heart rate
- B. Withhold the dose and notify the prescriber
- C. Give the dose with an extra glass of water
- D. Administer a prescribed bronchodilator first
Explanation
Digoxin can slow atrioventricular conduction and reduce the heart rate. A markedly low apical pulse requires withholding the dose and contacting the prescriber according to the medication protocol.
