A nurse is preparing to administer cefazolin 40 mg/kg/day IV bolus divided in equal doses every 12 hr to a neonate who weighs 5 kg Available is cefazolin injection 330 mg/mL. How many mL should the nurse administer per dose?

Answer and Explanation

The Correct Answer is ["0.3"]

To calculate the dose of cefazolin for a neonate, first multiply the weight by the dosage per day: 5 kg x 40 mg/kg/day = 200 mg/day. Then divide by the number of doses per day: 200 mg/day / 2 doses/day = 100 mg/dose. Next, use the formula D/H x Q to find the volume to administer, where D is the dose, H is the strength of the solution, and Q is the quantity of the solution. Plug in the values: 100 mg / 330 mg/mL x 1 mL = 0.3 mL. Round to the nearest tenth: 0.3 mL. Therefore, the nurse should administer 0.3 mL of cefazolin per dose.

Correct Answer is ["3.5"]

Explanation

To convert pounds to kilograms, divide by 2.2: 154 lb / 2.2 = 70 kg. Then multiply by the dosage per kilogram: 70 kg x 50 mcg/kg = 3500 mcg. Next, convert micrograms to milligrams by dividing by 1000: 3500 mcg / 1000 = 3.5 mg. Finally, use the formula D/H x Q to find the volume to administer, where D is the dose, H is the strength of the solution, and Q is the quantity of the solution. Plug in the values: 3.5 mg / 1 mg/mL x 1mL = 3.5 mL. Round to the nearest tenth: 3.5 mL. Therefore, the nurse should administer 3.5 mL of milrinone.

A. The medication can be used for IV administration. B. The medication can be used for up to 14 days after reconstitution. C. The vial contains a single dose. D. The medication should be reconstituted with 0.9% sodium chloride solution.

Correct Answer is A

Explanation

Choice A rationale: The medication can be used for IV administration or IM administration as indicated in the label. Methylprednisolone is a corticosteroid that can be given intravenously to treat inflammatory conditions such as asthma, allergic reactions, rheumatoid arthritis, and multiple sclerosis. The medication label should indicate the route of administration, the concentration, the expiration date, and the storage conditions.

Choice B rationale: According to the label, the medication should not be used for more than 48 hours after reconstitution, and it should be stored in a refrigerator.

Choice C rationale: The vial contains multiple doses, and each dose should be withdrawn with a sterile syringe.

Choice D rationale: The medication should be reconstituted with bacteriostatic water for injection, not with 0.9% sodium chloride.
