A nurse is preparing to administer vancomycin 1 g in 250 ml 0.9% sodium chloride by intermittent IV bolus over 90 min. The nurse should set the IV pump to deliver how many mL/hr?
(Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["167"]

To calculate the infusion rate for the IV pump, we need to divide the total volume of the solution (250 mL) by the infusion time (90 min). This gives us:

250 mL / 90 min = 2.778 mL/min

To convert this to mL/hr, we need to multiply by 60 min/hr. This gives us: 2.778 mL/min x 60 min/hr = 166.667 mL/hr

To round this to the nearest whole number, we look at the tenths place and see that it is 6, which is equal to or greater than 5, so we round up and drop the rest of the digits. This gives us:

167 mL/hr

Therefore, the nurse should set the IV pump to deliver 167 mL/hr.

Correct Answer is ["20"]

Explanation

To calculate the volume of medication to administer, use the formula: (desired dose / available dose) x available volume. Plug in the values: (25 mg / 6.25 mg) x 5 mL = 20 mL. Round to the nearest whole number: 20 mL.

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.
