If the available meperidine injection is 100 mg/mL, how many mL should the nurse administer?

Answer and Explanation

The Correct Answer is ["0.75 "]

Step 1: Calculate the volume of meperidine injection to administer. The available meperidine injection is 100 mg/mL, so 75 mg ÷ 100 mg/mL = 0.75 mL. The nurse should administer 0.75 mL of meperidine injection.

Correct Answer is D

Explanation

Choice A rationale

Storing the medication in a well-lit area is not necessary. Phenytoin oral suspension does not require light for storage.

Choice B rationale

While it’s important to store many medications in a cool area, phenytoin oral suspension does not specifically need to be stored in a cool area.

Choice C rationale

The total volume in a unit dose container is not typically 100 mL for phenytoin oral suspension. The volume can vary depending on the concentration and the specific product.

Choice D rationale

The unit dose container should indeed be gently rolled before administration. This is because phenytoin is an oral suspension, and suspensions consist of small drug particles dispersed throughout a liquid. Rolling the container helps ensure the drug particles are evenly distributed throughout the dose.

Correct Answer is ["1000 "]

Explanation

Step 1 is to calculate the total volume to be infused in mL/hr. This is done by dividing the total volume (250 mL) by the time in hours (15 min ÷ 60 min/hr). So, 250 mL ÷ (15 min ÷ 60 min/hr) = 1000 mL/hr.

So, the correct answer is 1000 mL/hr.
