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

A. Nausea: Nausea is a common gastrointestinal side effect of cefazolin, a first-generation cephalosporin. It may also be accompanied by vomiting, diarrhea, or abdominal discomfort. The nurse should monitor for these symptoms and report persistent or severe cases. B. Hypertension: Cefazolin is not typically associated with elevated blood pressure. Hypertension is not a known adverse effect of this antibiotic, so monitoring blood pressure specifically for this reason is unnecessary unless the child has other risk factors. C. Increased appetite: Cefazolin does not cause increased appetite. Antibiotics generally do not enhance appetite and may even decrease it due to GI side effects like nausea or dyspepsia. D. Constipation: Constipation is not a typical side effect of cefazolin. If GI symptoms occur, they are more likely to involve diarrhea or nausea rather than decreased bowel motility.
