A nurse is preparing to administer metronidazole 500 mg by intermittent bolus over 60 min. Available is metronidazole 500 mg in 100 ml 0.9% sodium chloride. 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 ["100"]

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.

Correct Answer is ["25"]

Explanation

To calculate the IV flow rate in gtt/min, you need to multiply the infusion rate in mL/hr by the drop factor in gtt/mL and divide by 60 min/hr. In this case, the formula is (75 mL/hr x 20 gtt/mL) / 60 min/hr = 25 gtt/min. Therefore, the nurse should set the IV flow rate to deliver 25 gtt/min.

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Choice C rationale: The vial contains multiple doses, and each dose should be withdrawn with a sterile syringe.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