A nurse is preparing to administer digoxin to a 6-month-old infant. Before 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? .

Choice A rationale
Decreased muscle tone is not typically associated with neonatal abstinence syndrome (NAS). NAS is a condition that affects newborns who have been exposed to addictive opiate drugs while in the mother’s womb.
Choice B rationale
Sleeping for 2 hours after feeding is not a specific symptom of NAS. While changes in sleep patterns can occur in NAS, they are not definitive indicators of the condition.
Choice C rationale
A continuous high-pitched cry is a common symptom of NAS123. This is because the baby is going through withdrawal from the drugs they were exposed to in the womb.
Choice D rationale
Mild tremors when disturbed are indeed a symptom of NAS123. However, this symptom alone is not enough to diagnose NAS as it can be seen in other conditions as well.

Choice A rationale
While gastrointestinal symptoms can occur in Kawasaki disease, such as diarrhea, vomiting, and abdominal pain, the primary system affected is not the gastrointestinal system.
Choice B rationale
Although Kawasaki disease can cause symptoms such as a rash and changes in the lips and oral cavity, which are related to the integumentary system, the primary system affected is not the integumentary system.
Choice C rationale
Respiratory symptoms are not typically a primary concern in Kawasaki disease. While a child with Kawasaki disease may have some respiratory symptoms such as a cough and runny nose, these are not the main focus of monitoring.
Choice D rationale
Kawasaki disease is a systemic vasculitis that predominantly affects the cardiovascular system. It is the leading cause of acquired heart disease in children. Therefore, monitoring the cardiovascular system is crucial in managing a child with Kawasaki disease.
