A 6-month-old infant is receiving digoxin (Lanoxin). The nurse should notify the practitioner and withhold the medication if the apical pulse is less than _______ beats/min.
- A. 60
- B. 70
- C. 90 to 110
- D. 110 to 120
Correct Answer: C
Rationale: If the 1-minute apical pulse is below 90 to 110 beats/min, the digoxin should not be given to a 6-month-old. Sixty beats/min is the cut-off for holding the digoxin dose in an adult; 70 beats/min is the determining heart rate to hold a dose of digoxin for an older child; 110 to 120 beats/min is an acceptable heart rate to administer digoxin to a 6-month-old.
