A nurse is caring for a client who has atrial fibrillation and receives digoxin daily. Before administering this medication, which of the following actions should the nurse take?

A. While blood pressure monitoring is important in some cardiac conditions, it is not the priority before giving digoxin. B. Daily weight helps monitor fluid status, especially in heart failure, but it is not required immediately before administration of digoxin. C. Measuring the apical pulse is essential before administering digoxin, as it can cause bradycardia. The nurse should withhold the dose and notify the provider if the pulse is below the prescribed threshold (usually 60 bpm). D. A light snack is not contraindicated, but it is not a priority action before giving this medication.
