A nurse is preparing to administer chlorpromazine 50 mg IM to a client. Available is chlorpromazine 25 mg/mL. How many mL should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["2"]
Step 1: The dose to be administered is50 mg of chlorpromazine.
Step 2: The available chlorpromazine injection has a concentration of25 mg/mL. This means that for every 1 mL of the solution, there are 25 mg of chlorpromazine.
Step 3: To find out how many mL should be administered, we divide the dose by the concentration. So, 50 mg ÷ 25 mg/mL = 2 mL.
The nurse should administer 2 mL of chlorpromazine injection.

Correct Answer is ["2"]
Explanation
Step 1: The total daily dose to be administered is300 mg of trazodone.
Step 2: The total daily dose is divided equally every 8 hours, so each dose is one third of the total daily dose. So, 300 mg ÷ 3 =100 mg per dose.
Step 3: The available trazodone tablets have a concentration of50 mg/tablet. This means that for every 1 tablet, there are 50 mg of trazodone.
Step 4: To find out how many tablets should be administered per dose, we divide the dose by the concentration. So, 100 mg ÷ 50 mg/tablet =2 tablets.
The nurse should administer 2 tablets of trazodone in each dose.
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.
