A nurse is assessing a school-age child who is receiving cefazolin. For which of the following adverse effects should the nurse monitor?

A. Increased appetite: Cefazolin, a cephalosporin antibiotic, does not typically cause an increase in appetite. Instead, gastrointestinal upset such as nausea, vomiting, or diarrhea is more common with this class of drugs. B. Nausea: Gastrointestinal disturbances, including nausea, vomiting, and diarrhea, are frequent adverse effects of cefazolin. The nurse should monitor for these symptoms as they can affect fluid and nutritional status, especially in children. C. Hypertension: Cefazolin is not associated with increased blood pressure. Adverse effects more commonly involve gastrointestinal symptoms, hypersensitivity reactions, and, in rare cases, nephrotoxicity or superinfections. D. Constipation: Constipation is not a typical adverse effect of cefazolin therapy. Instead, diarrhea is more commonly reported due to alterations in normal gastrointestinal flora during antibiotic use.
