A nurse is preparing to administer diphenhydramine 50 mg PO every 6 hours to a client who has acute dystonia.

Available are diphenhydramine 25 mg tablets. How many tablets should the nurse administer per dose?

(Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["2"]

Step 1: The total amount of diphenhydramine required per dose is 50 mg.

Step 2: Each tablet contains 25 mg of diphenhydramine.
Step 3: To find out how many tablets are needed, we divide the total amount required by the amount in each tablet. So, 50 mg ÷ 25 mg/tablet.
Step 4: The result is 2 tablets.
So, the nurse should administer 2 tablets per dose. This is already a whole number, so no rounding is necessary.

Correct Answer is A

Explanation

Choice A reason: Ice cream is considered a fluid in dietary terms, so not counting it as part of fluid intake shows a misunderstanding.

Choice B reason: Making a list of favorite beverages does not demonstrate understanding of fluid restrictions.

Choice C reason: Putting beverages in large containers does not reffect an understanding of fluid restrictions and could lead to overconsumption.

Choice D reason: Consuming most fluid during the evening could lead to fluid overload overnight, which is not advisable.

A. Ensure that the client's urine output is at least 1 mL/kg/hour. B. Educate the client regarding high-potassium food sources. C. Cardiac monitoring during infusion. D. Repeat blood serum potassium. E. Ensure potassium infusion is prepared with 5% dextrose solution.

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

Explanation

Choice A reason: Ensuring the client's urine output is at least 1 mL/kg/hour is important before administering potassium to prevent hyperkalemia, especially in clients with renal impairment.

Choice B reason: While educating the client about high-potassium food sources is important, it is not directly related to the administration of intravenous potassium.

Choice C reason: Cardiac monitoring during infusion is crucial due to the risk of arrhythmias associated with rapid

changes in potassium levels.

Choice D reason: Repeating blood serum potassium is necessary to monitor the effectiveness of the supplementation and avoid hyperkalemia.

Choice E reason: Potassium should not be prepared with 5% dextrose solution as it may cause a trans-cellular shift of potassium into cells, which is not recommended.
