A nurse is caring for a client who has a prescription for digoxin 0.25 mg PO daily for heart failure. The client's current vital signs are: BP 144/96, heart rate 54/min, respirations 18/min, and temperature 37° C (98.6° F). Which of the following actions should the nurse take?

A. Withhold the digoxin dose for elevated BP: Elevated BP is not a contraindication for digoxin administration; rather, the heart rate is the critical factor. B. Withhold the digoxin dose for decreased heart rate. A heart rate below 60 beats per minute is a contraindication for administering digoxin, as it can increase the risk of toxicity and bradycardia. C. Administer digoxin 0.25 mg. Given the heart rate of 54/min, the nurse should not administer the full dose. D. Administer digoxin 0.125 mg. While 0.125 mg may be appropriate in some cases, the heart rate should first be assessed to determine if the medication should be administered at all.
