A nurse is preparing to administer perphenazine 200 mg divided into four equal doses daily to a client who has psychosis. Available is perphenazine oral solution16 mg/mL. How many mL should the nurse administer per dose? Round the answer to the nearest tenth. (Use a leading zero if it applies. Do not use trailing zeros.)
The Correct Answer is ["3.1"]
Given:
- Total perphenazine to be administered: 200 mg
- The medication is to be divided into four equal doses
- Available perphenazine oral solution: 16 mg/mL
Step 1: Calculate the amount of perphenazine per dose
200 mg ÷ 4 = 50 mg/dose
Step 2: Calculate the volume of the oral solution per dose
(50 mg/dose) ÷ (16 mg/mL) = 3.125 mL/dose
Rounding to the nearest tenth, the nurse should administer 3.1 mL

Correct Answer is ["2"]
Explanation
Step 1: The dose to be administered is25 mg of risperidone.
Step 2: The available risperidone injection has a concentration of25 mg/2 mL. This means that for every 2 mL of the solution, there are 25 mg of risperidone.
Step 3: To find out how many mL should be administered, we divide the dose by the concentration. So, 25 mg ÷ (25 mg/2 mL) = 2 mL.
The nurse should administer 2 mL of risperidone injection.
Correct Answer is B
Explanation
The correct answer is choice B: Dosage.
Choice A rationale: The medication name is an essential component of a medication prescription, identifying the specific medication to be administered. In this case, the medication name is already provided as "Zopiclone."
Choice B rationale: Dosage is a crucial element of a medication prescription, indicating the amount of the medication to be administered. Although the prescription mentions "1 tablet," the strength or dosage of the Zopiclone tablet (e.g., 5 mg, 7.5 mg) is missing. The nurse should ask the provider to specify the dosage to ensure accurate and safe medication administration.
Choice C rationale: Frequency refers to how often the medication should be taken. The given prescription states "at bedtime," which specifies when the medication should be administered.
Choice D rationale: Route describes the method used to administer the medication. This prescription mentions the route as "PO," which stands for "by mouth" (per os).
In conclusion, a nurse should ensure that a medication prescription includes all essential components, such as medication name, dosage, frequency, and route. In this case, the dosage of Zopiclone is missing, and the nurse should ask the provider to add this information to the prescription to ensure accurate and safe administration of the medication.
