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 health care provider is notified?

A. Digoxin: Digoxin is a cardiac glycoside that can cause toxicity if the heart rate is too low. For infants, the apical pulse should typically be greater than 90-110 beats per minute before administration. Since this infant has an apical pulse of 88 beats/minute, the nurse should withhold digoxin and notify the healthcare provider for further evaluation. B. Enalapril: Enalapril is an ACE inhibitor used to treat heart failure and hypertension. It can generally be administered as prescribed, regardless of the current heart rate, but blood pressure should be monitored. C. Furosemide: Furosemide is a diuretic commonly used in heart failure management to reduce fluid overload. It can be administered safely at this time, as it does not have the same pulse considerations as digoxin. D. Hydralazine: Hydralazine is a vasodilator used to manage hypertension and improve cardiac output. It can be administered without concern for the current heart rate, although blood pressure should be monitored.
