A nurse is collecting data on a client who has a new prescription for ampicillin. The nurse should recognize which of the following findings is a priority?

A. Wheezing: Wheezing is a priority finding. It may indicate an allergic reaction to ampicillin, which could progress to anaphylaxis. Anaphylaxis is a life-threatening emergency that requires immediate intervention. B. Moniliasis: Moniliasis, or a yeast infection (commonly oral or vaginal candidiasis), is a potential side effect of antibiotics like ampicillin, but it is not an immediate life-threatening issue. It is important to monitor, but it is not a priority compared to wheezing. C. Vomiting: Vomiting can be a common side effect of many medications, including ampicillin. While it should be monitored and managed, it is not as urgent as symptoms of a serious allergic reaction. D. Nausea: Nausea is also a common side effect of ampicillin. Like vomiting, it can be uncomfortable but is not as urgent as signs of an allergic reaction such as wheezing.
