A nurse is preparing to administer digoxin to a 6-month-old infant. Prior to administering the dose, the nurse measures the apical heart rate. The nurse should withhold the dose if the infant's apical heart rate is less than what rate?
The Correct Answer is ["90"]
The nurse should withhold the dose if the infant's apical heart rate is less than 90 beats per minute.
Digoxin is a medication that can slow the heart rate. If an infant's heart rate is already too slow, administering digoxin can increase the risk of bradycardia, a serious heart rhythm disturbance.
It's important to monitor the apical heart rate for a full minute before administering digoxin to an infant and to withhold the dose if the heart rate is below the specified threshold.

D. Foul-smelling ribbon-like stools
Explanation:
Hirschsprung's disease is a congenital condition characterized by the absence of ganglion cells in the rectum and a portion of the colon. The lack of ganglion cells results in functional obstruction, causing stool to accumulate in the affected area. One of the hallmark signs is the presence of foul-smelling, ribbon-like stools, often described as "fecal pellets" or "pellets" due to the obstructed passage of stool.
