A nurse is preparing to administer trazodone 300 mg PO daily, divided equally every 8 hours, to a client who has depression. Available are trazodone 50 mg tablets. How many tablets should the nurse administer in each dose? (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 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 D
Explanation
The correct answer is choice D. Route.
Choice A rationale:
The medication name, lorazepam, does not need clarification as it is a commonly prescribed benzodiazepine, known for its effectiveness in treating anxiety and its off-label use as a sleep aid.
Choice B rationale:
The dosage of 4 mg at bedtime falls within the typical dosing range for lorazepam when used for insomnia caused by anxiety or transient situational stress in adults. However, it is on the higher end of the spectrum, and lower doses are often recommended, especially for older adults.
Choice C rationale:
The frequency, ‘at bedtime’, is appropriate for lorazepam when prescribed as a sleep aid, as it is typically taken as a single dose at night.
Choice D rationale:
The route should be clarified. Lorazepam can be administered orally in tablet form or as an oral solution, and the prescription should specify this to ensure proper administration. Additionally, if the patient has difficulty swallowing, the route of administration might need to be adjusted, and alternative forms like an injectable route could be considered.
Correct Answer is ["2"]
Explanation
Step 1: The total daily dose to be administered is60 mg of fluoxetine.
Step 2: The total daily dose is divided equally every 12 hours, so each dose is half of the total daily dose. So, 60 mg ÷ 2 =30 mg per dose.
Step 3: The available fluoxetine tablets have a concentration of15 mg/tablet. This means that for every 1 tablet, there are 15 mg of fluoxetine.
Step 4: To find out how many tablets should be administered per dose, we divide the dose by the concentration. So, 30 mg ÷ 15 mg/tablet =2 tablets.
The nurse should administer 2 tablets of fluoxetine per dose.
