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
Monitoring vaginal bleeding is the priority nursing action for a client who is at 33 weeks of gestation and has a diagnosis of placenta previa. Placenta previa can cause painless, bright red vaginal bleeding during the third trimester. This bleeding can lead to serious complications for both the mother and the fetus, making it crucial to monitor for this symptom.
Choice B rationale
Administering glucocorticoids is not the priority nursing action in this situation. While glucocorticoids can be used to accelerate fetal lung maturity in cases of preterm labor, they are not the primary treatment for placenta previa.
Choice C rationale
Inserting an IV catheter may be necessary for administering medications or fluids, but it is not the priority action. The nurse’s primary concern should be monitoring for signs of bleeding.
Choice D rationale
Applying an external fetal monitor can help assess the well-being of the fetus, but it is not the priority action. The nurse’s main focus should be on monitoring for vaginal bleeding.

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.
