A nurse is planning care for a client who is to receive a prescription for IV vancomycin. Which of the following interventions should the nurse include in the plan?

A. Elevated blood pressure: Excess fluid in the vascular system increases circulating volume, which raises blood pressure. This is a common early sign of fluid overload and can lead to additional complications if not addressed promptly.

B. Decreased pulse rate: Fluid overload typically causes an increased pulse rate as the heart works harder to manage the extra volume. A decreased pulse is not a usual manifestation of fluid overload.

C. Decreased gastrointestinal motility: Fluid overload does not directly reduce gastrointestinal motility. Bowel slowing is more commonly associated with medications, immobility, or other systemic conditions rather than excess IV fluid.

D. Flattened neck veins: Fluid overload usually causes distended neck veins due to increased central venous pressure. Flattened neck veins suggest hypovolemia or low circulating blood volume rather than overload.

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 (325mL/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.
