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 rationale: Potassium is primarily excreted by the kidneys. While adequate renal function is necessary, the standard minimum urine output for adults is 30 mL/hour rather than 1 mL/kg/hour.

Choice B rationale: Low potassium levels (2.5 mEq/L) require long-term management. Educating the client on potassium-rich foods like bananas and potatoes helps prevent future depletion and supports overall electrolyte balance.

Choice C rationale: Severe hypokalemia and rapid IV replacement increase the risk of lethal cardiac dysrhythmias. Continuous ECG monitoring is vital to detect life-threatening changes in cardiac conduction and rhythm.

Choice D rationale: Following intravenous replacement, serum levels must be re-evaluated to confirm the effectiveness of the treatment and ensure the client does not develop iatrogenic hyperkalemia.

Choice E rationale: Dextrose stimulates insulin secretion, which causes an intracellular shift of potassium. This can lead to a further decrease in serum potassium levels, worsening the client's hypokalemia.

Choice A reason: Increased urinary output is not typically associated with peritonitis, especially during peritoneal

dialysis.

Choice B reason: Bradycardia, or a slow heart rate, is not a common manifestation of peritonitis.

Choice C reason: Nausea and vomiting are common symptoms of peritonitis and should be monitored in clients

receiving peritoneal dialysis.

Choice D reason: Hyperactive bowel sounds are not specifically indicative of peritonitis; they can be associated with a variety of gastrointestinal conditions.
