A nurse is reviewing a provider's prescription for IV fluid therapy for a client who has fluid volume deficit. Which of the following units of measurement should the nurse use to administer the fluid using an IV pump?

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.

A. Temperature: Nifedipine does not directly affect body temperature, so assessing temperature is not critical prior to administration.

B. Respiratory rate: While monitoring respiratory status is important in general, nifedipine primarily affects the cardiovascular system, so respiratory rate is not the primary assessment focus.

C. Blood pressure: Nifedipine is a calcium channel blocker that lowers blood pressure by relaxing vascular smooth muscle. Assessing blood pressure before administration ensures the client is not hypotensive and helps prevent adverse cardiovascular effects.

D. Oxygen saturation: Oxygen saturation is not directly impacted by nifedipine, so it is not essential to assess this parameter prior to giving the medication.
