A nurse is teaching a client about self-administered peritoneal dialysis. Which of the following statements by the client indicates a need for further teaching?

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: 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.
