A nurse is caring for a client on a medical-surgical unit. Complete the following sentence by using the lists of options. Exhibits The nurse should first dropdown due to the client’s dropdown.

Rationale for Correct Choices: Stop the IV infusion: The client is showing signs of a severe allergic reaction, including flushing, generalized itching, hypotension, tachycardia, hypoxia, and difficulty breathing shortly after vancomycin administration. Immediate cessation of the infusion is critical to prevent progression of anaphylaxis. Anaphylaxis: The client is exhibiting the classic signs of an anaphylactic-type reaction. The rapid infusion rate (325 mL/hr) is very high for Vancomycin and often causes Red Man Syndrome, which is a histamine release reaction. However, the presence of difficulty breathing elevates this to anaphylactic or severe hypersensitivity reaction, requiring the most urgent response. Rationale for Incorrect Choices: Administer epinephrine: Epinephrine is the first-line treatment for anaphylaxis, but it is administered after stopping the offending agent. Halting the infusion is the initial, priority nursing action. Request a serum peak drug level: Monitoring vancomycin peak or trough levels is important for toxicity prevention, but it is not the immediate priority during an acute hypersensitivity reaction. Nephrotoxicity: Elevated WBC or vancomycin trough does not indicate acute nephrotoxicity here, and the patient’s acute symptoms are consistent with an allergic reaction rather than kidney injury. Sepsis: Although the client has cellulitis and elevated WBCs, the sudden onset of hypotension, flushing, and respiratory distress after IV antibiotic administration is more indicative of anaphylaxis rather than sepsis.
