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.)

Choice A reason: Frothy urine is not a typical symptom of pyelonephritis; it is more associated with proteinuria or nephrotic syndrome.

Choice B reason: Lower abdominal pain can be a symptom of pyelonephritis due to in?ammation and infection in the kidneys.

Choice C reason: Hypertension is not a direct symptom of pyelonephritis, although it can be associated with chronic kidney disease.

Choice D reason: A fish-type urine odor can be present in pyelonephritis due to the presence of bacteria.

Choice E reason: Mental confusion can occur, especially in severe cases or in elderly patients with pyelonephritis.

Choice F reason: A weak urine stream may be present if there is swelling or obstruction in the urinary tract due to infection.

Choice A reason: The normal range for serum creatinine in adult females is approximately 0.6–1.1 mg/dL. A level of 1.8 mg/dL is elevated and indicates impaired kidney function, which is a risk factor for AKI.

Choice B reason: Normal BUN levels are generally between 6 to 24 mg/dL⁸. A BUN level of 200 mg/dL is significantly elevated and suggests kidney dysfunction, which can lead to AKI.

Choice C reason: Serum osmolality in the normal range, which is typically between 275 to 295 mOsm/kg H2O for adults⁹[13][^10^][14][16], does not indicate an increased risk of AKI.

Choice D reason: The normal range for serum magnesium is typically 1.7 to 2.2 mg/dL or 0.85 to 1.10 mmol/L. A level of 2.0 mEq/L (which is equivalent to 2.0 mg/dL) is within the normal range and does not indicate an increased risk for AKI.
