A nurse is preparing to administer digoxin to a 12 year-old child. Prior to administering the dose. the nurse measures the apical heart rate. The nurse should withhold the dose if the child's apical heart rate is less than what rate?

Answer and Explanation

The Correct Answer is ["70"]

The nurse should withhold digoxin if the child's apical heart rate is less than 70 beats per minute because digoxin slows the conduction of electrical signals in the heart and increases the force of cardiac contraction. While this helps to treat conditions like heart failure and arrhythmias, it can also lead to bradycardia. Administering digoxin when the heart rate is already too low increases the risk of adverse effects like severe bradycardia or even cardiac arrest.
