An 8-month-old infant is receiving Digoxin. The nurse should notify the practitioner and withhold the medication if the apical pulse is less than which of the following?

A. 90 bpm is too low for an 8-month-old infant and not the standard threshold for withholding digoxin in this age group. B. 60 bpm is the cutoff for adults, not infants. C. 120 bpm is normal for an infant and does not warrant holding digoxin. D. Correct. For infants, digoxin should be withheld and the provider notified if the apical heart rate is less than 100 beats per minute, due to the risk of bradycardia and digoxin toxicity.
