Nokea
The nurse is reviewing new postoperative orders and notes that the order reads, 'Give hydroxyzine 50 mg IV PRN nausea or vomiting.' The patient states that he has slight nausea. Which action by the nurse is correct at this time?
- A. Hold the dose until the patient states that the nausea is severe.
- B. Give the dose orally instead of intravenously.
- C. Give the patient the IV dose of hydroxyzine as ordered.
- D. Call the prescriber to question the route that is ordered.
Correct Answer: D
Rationale: The nurse needs to question the route. Hydroxyzine is an antihistamine-class antiemetic that is only to be given either by oral or intramuscular routes. Intravenous, intra-arterial, or subcutaneous administration of hydroxyzine may result in significant tissue damage, thrombosis, and gangrene. Antiemetic drugs are best given before the patient's nausea becomes severe.

An adult patient is about to receive intravenous (IV) ondansetron during a chemotherapy treatment. A dose of 0.15 mg/kg IV 30 minutes before chemotherapy is ordered. The patient weighs 165 pounds. The medication is supplied in a vial marked 2 mg/mL for IV administration. Identify how many milliliters the nurse will administer for this dose. (Record answer to one decimal place.)
Correct Answer: 5.7 mL
Rationale: Convert pounds to kilograms: 165 ?· 2.2 = 75 kg. Calculate milligrams per dose: 0.15 mg/kg ?? 75 kg = 11.25 mg, rounded to 11.3 mg/dose. Calculate milliliters to be given: 2 mg:1 mL::11.3 mg:x mL, (2 ?? x) = (1 ?? 11.3); 2x = 11.3, x = 5.65, which rounds to 5.7 mL.
