A nurse is caring for a client who has a prescription for digoxin 0.25 mg PO daily. The amount available is digoxin 0.125 mg tablets. The client's current vital signs are: blood pressure 144/96, heart rate 54/min, respirations 18/min, and temperature 98.6°F. Which of the following actions should the nurse take?

Choice A reason: Administering 2 tablets of digoxin 0.125 mg would provide the correct dosage of 0.25 mg. However, given the client's heart rate of 54/min, administering the medication could further lower the heart rate, which can be dangerous. The nurse should withhold the medication and notify the physician.Choice B reason: Withholding the digoxin dose for decreased heart rate is the correct action. Digoxin is used to slow down the heart rate and strengthen heart contractions. A heart rate of 54/min is considered bradycardia (slow heart rate), and administering digoxin could exacerbate the bradycardia, leading to potential complications such as heart block or severe arrhythmias. Therefore, it is critical to withhold the medication and inform the physician of the client's current heart rate.Choice C reason: Administering one tablet of digoxin 0.125 mg would not provide the full prescribed dose of 0.25 mg. More importantly, the client's low heart rate makes it unsafe to administer any dose of digoxin at this time.Choice D reason: Withholding the digoxin dose for elevated blood pressure is not appropriate. Although the client has elevated blood pressure (144/96), the more immediate concern is the low heart rate. Digoxin affects heart rate more than blood pressure, and the risk of exacerbating bradycardia takes precedence.
