A nurse is preparing to administer aripiprazole 9 mg IM to a client. Available is aripiprazole injection 9.75 mg/3 mL. How many mL should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["2.8"]
Step 1: The dose to be administered is9 mg of aripiprazole.
Step 2: The available aripiprazole injection has a concentration of9.75 mg/3 mL. This means that for every 3 mL of the solution, there are 9.75 mg of aripiprazole.
Step 3: To find out how many mL should be administered, we divide the dose by the concentration. So, 9 mg ÷ (9.75 mg/3 mL) = 2.769230769230769 mL.
Step 4: Round the answer to the nearest tenth. So, 2.769230769230769 mL rounds to2.8 mL.
The nurse should administer 2.8 mL of aripiprazole 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.
