A nurse is preparing to administer codeine 20 mg PO every 6 hours as needed for pain.

If the available codeine oral solution is 10 mg/5 mL, how many mL should the nurse administer per dose?

Answer and Explanation

The Correct Answer is ["10 "]

Step 1 is to calculate the volume of codeine to administer. Given that the available codeine oral solution is 10 mg/5 mL and the nurse needs to administer 20 mg, the calculation is as follows: 20 mg ÷ (10 mg/5 mL) = 10 mL4

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 ["2"]

Explanation

The nurse should administer 2 tablets of famotidine. Here’s the calculation: Step 1: The total dosage required is 40 mg.

Step 2: Each tablet contains 20 mg of famotidine.

Step 3: So, the number of tablets required is 40 mg ÷ 20 mg/tablet = 2 tablets.
