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 D

Explanation

Choice A reason: Hypernatremia, which is an abnormally high level of sodium in the blood, is not typically associated with prerenal AKI. Prerenal AKI is often related to hypovolemia, which can lead to hyponatremia rather than hypernatremia.

Choice B reason: Hypophosphatemia, or low levels of phosphate in the blood, is not a common finding in prerenal AKI. Phosphate levels are more often affected in intrinsic renal diseases or refeeding syndrome.

Choice C reason: Hypercalcemia, or high levels of calcium in the blood, is not commonly seen in prerenal AKI. It is more frequently associated with malignancies or hyperparathyroidism.

Choice D reason: Hyperkalemia, which is an elevated level of potassium in the blood, is a common electrolyte imbalance in prerenal AKI. This occurs due to decreased renal perfusion and the kidney's reduced ability to excrete potassium.

A. The client states that they consume a high calcium diet and have had high calcium in their blood. B. The client reports that they had two urinary tract infections (UTI) in the past 10 months. C. The client reports that they took a lot of ibuprofen for arthritis for many years. D. The client states that they remember their mother saying their grandmother had this same genetic disease.

Correct Answer is B

Explanation

Choice A reason: A high calcium diet and high blood calcium levels are not directly related to pyelonephritis.

Choice B reason: Recurrent UTIs can lead to pyelonephritis, especially if the infections ascend to the kidneys.

Choice C reason: Long-term use of ibuprofen can affect kidney function but is not a direct cause of pyelonephritis.

Choice D reason: Genetic diseases can affect kidney health, but there is no common genetic disease that directly causes pyelonephritis.
