A nurse is reinforcing teaching with an adolescent who has a new prescription for cefazolin. For which of the following findings should the nurse instruct the adolescent to monitor and report to the provider?

Answer: B. Elevated skin patches Rationale: A. Constipation: Constipation is not a typical adverse effect of cefazolin. Antibiotics generally cause gastrointestinal symptoms like diarrhea rather than constipation, so this is not a primary concern with cefazolin therapy. B. Elevated skin patches: Elevated skin patches may indicate an allergic reaction, such as hives or a rash, which can be a serious side effect of cefazolin. Allergic reactions to antibiotics can escalate quickly and may require immediate medical attention. Monitoring for and reporting any skin changes is important to prevent potential complications. C. Ringing in the ears: Tinnitus (ringing in the ears) is not commonly associated with cefazolin. This symptom is more frequently associated with certain other antibiotics, such as aminoglycosides, but is not a primary concern with cefazolin use. D. Depression: Depression is not a known side effect of cefazolin. While mood changes may be seen with some medications, cefazolin’s primary side effects are related to hypersensitivity reactions and gastrointestinal symptoms.
