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 ["100"]

Explanation

To calculate the IV pump rate in mL/hr, you need to divide the volume of the solution in mL by the infusion time in hr. In this case, the formula is 100 mL / 1 hr = 100 mL/hr.

Therefore, the nurse should set the IV pump to deliver 100 mL/hr of metronidazole.

A. The medication is for IV administration. B. The total amount available per container is 4 mL. C. The nurse should avoid shaking the medication. D. The medication should not be stored below 30 C(86 F)

Correct Answer is C

Explanation

Choice A rationale: Phenytoin is an anticonvulsant medication that is used to treat seizures. It can be given orally or intravenously, but the IV route requires careful preparation and monitoring. According to the medication label, the phenytoin is in form of an oral suspension hence it should be administered orally.

Choice B rationale: the total amount available per container is usually 5 mL not 4 mL. Choice C rationale: Phenytoin suspension should not be shaken, as it may cause the drug to precipitate. Shaking it could lead to inaccurate dosing.

Choice D rationale: The medication should also be stored at room temperature and protected from light.
