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

A. Hypotension: Hypotension is not a common adverse effect of cefazolin. While severe allergic reactions can cause hypotension, it is not a typical side effect to monitor for with cefazolin specifically. B. Stevens-Johnson syndrome: Correct. Stevens-Johnson syndrome (SJS) is a rare but serious adverse effect of many antibiotics, including cefazolin. SJS is a severe skin reaction that requires immediate medical attention. C. Prolonged wound healing: Cefazolin is an antibiotic and would not typically cause prolonged wound healing; instead, it is used to prevent or treat infections that might impair healing. D. Bradypnea: Bradypnea is not associated with cefazolin. Respiratory depression is not a common side effect of this antibiotic.
