A nurse is caring for a client who is receiving vancomycin IV. Which of the following findings should the nurse document as an adverse reaction to this medication?

Nursing care for a client receiving Vancomycin includes monitoring for infusion-related reactions and signs of toxicity. Vancomycin is commonly used to treat serious gram-positive infections, including resistant organisms such as MRSA. One important adverse effect is “red man syndrome,” which occurs with rapid IV infusion and presents with flushing, rash, and itching of the upper body. Early recognition allows prompt intervention and prevention of more severe complications. Rationale: A. Reddish-orange colored urine is not an expected adverse effect of vancomycin and is more commonly associated with medications such as rifampin. Vancomycin is more closely linked to nephrotoxicity and ototoxicity rather than urine discoloration. If this finding occurs, the nurse should consider other medications or causes rather than attributing it to vancomycin. B. Dizziness when sitting up in bed may indicate orthostatic hypotension, dehydration, or another unrelated issue, but it is not a classic adverse reaction of vancomycin therapy. Although infusion reactions can affect blood pressure, the hallmark finding is flushing and rash rather than positional dizziness. Monitoring should focus more on infusion-related symptoms and renal function. C. Increased systolic blood pressure is not a typical adverse effect of vancomycin. Infusion-related reactions are more likely to cause hypotension, especially if the medication is administered too rapidly. The nurse should be more concerned about flushing, tachycardia, and hypotension than elevated blood pressure during IV administration. D. Rash over the face and neck is a classic sign of vancomycin infusion reaction known as red man syndrome. This occurs when the medication is infused too quickly and causes histamine release, leading to flushing, pruritus, and erythematous rash, especially on the face, neck, and upper torso. Slowing the infusion rate and monitoring the client closely are important nursing actions.
