The nurse is preparing to administer medications for an eight-month-old infant with heart failure. The infant has a blood pressure of 114/66 mm Hg, apical pulse of 88 beats/minute, and respirations of 30 breaths/minute. Which medication should the nurse withhold until the healthcare provider is notified?

For an eight-month-old infant with heart failure, the nurse should withhold digoxin if the infant's apical pulse is less than 90 beats/minute and notify the healthcare provider. In this case, the infant's apical pulse is 88 beats/minute, so the nurse should withhold the digoxin and notify the healthcare provider. Furosemide ( B), hydralazine (C), and enalapril (D) do not have specific parameters for withholding based on the infant's vital signs.
