A nurse is preparing to administer diphenhydramine 50 mg PO every 6 hr to a client who has acute dystonia. The available medication is diphenhydramine 25 mg tablets.

How many tablets should the nurse administer per dose?

Answer and Explanation

The Correct Answer is ["2"]

The nurse should administer 2 tablets per dose.

Rationale:

Step 1: Determine the desired dose of diphenhydramine. The desired dose is 50 mg.

Step 2: Determine the available tablet strength. The available tablet strength is 25 mg.

Step 3: Divide the desired dose by the tablet strength to determine the number of tablets needed. 50 mg / 25 mg/tablet = 2 tablets

Therefore, the nurse should administer 2 tablets of diphenhydramine 25 mg per dose to achieve the desired dose of 50 mg.

Correct Answer is ["A","D"]

Explanation

Choice A rationale: Fluoxetine, also known as Prozac, is a type of antidepressant known as a selective serotonin reuptake inhibitor (SSRI). It works by increasing the amount of serotonin, a natural substance in the brain that helps maintain mental balance. One of the common side effects of fluoxetine is a decreased interest in sexual intercourse. This can manifest as a decreased sex drive, difficulty in achieving an orgasm, or inability to have or keep an erection. It’s important for patients to be aware of this potential side effect so they can discuss it with their healthcare provider if it becomes a concern.

Choice B rationale: While fluoxetine is an effective treatment for depressive disorders, it does not typically cause an improvement in depressive symptoms in 2 to 3 days. In fact, it may take several weeks before patients begin to feel the full benefits of fluoxetine. Some people may even feel worse before they start to feel better. This is because it takes some time for fluoxetine to adjust the chemical balance in the brain.

Choice C rationale: Drooling is not typically associated with the use of fluoxetine. While fluoxetine can have many side effects, drooling is not commonly reported. If a patient experiences this side effect, it may be due to another medication or a different medical condition. It’s always important to discuss any new or unusual symptoms with a healthcare provider.

Choice D rationale: Loss of appetite is another potential side effect of fluoxetine. This can lead to weight loss in some patients. While this may be desirable for some, it can also lead to malnutrition and other health problems if not properly managed. Patients should be advised to monitor their weight and dietary intake while taking fluoxetine, and to discuss any concerns with their healthcare provider.

Correct Answer is ["1.5"]

Explanation

Step 1 is to determine the total amount of medication needed, which is 300 mg.

Step 2 is to determine the amount of medication available per tablet, which is 200 mg.

Step 3 is to calculate the number of tablets needed by dividing the total amount of medication needed by the amount available per tablet.

So, the calculation is: 300 mg ÷ 200 mg/tablet = 1.5 tablets Therefore, the nurse should administer 1.5 tablets.
