A nurse is caring for a patient in acute renal failure who develops muscle weakness and an irregular heart rhythm. The provider prescribes an IV infusion of hypertonic glucose, regular insulin, and sodium bicarbonate. The nurse recognizes that these treatments are intended to manage which of the following complications?
Hypoglycemia
Hyperkalemia
Hypernatremia
Hypokalemia
The Correct Answer is B
Choice A reason: Hypoglycemia involves low blood glucose, causing symptoms like shakiness or confusion, not muscle weakness or arrhythmias. Hypertonic glucose and insulin would worsen hypoglycemia by increasing glucose uptake, and sodium bicarbonate is irrelevant. These symptoms and treatments align with hyperkalemia, not low glucose levels, in renal failure.
Choice B reason: Hyperkalemia, common in acute renal failure due to impaired potassium excretion, causes muscle weakness and cardiac arrhythmias by altering membrane potentials. Hypertonic glucose and insulin drive potassium into cells, while sodium bicarbonate corrects acidosis, stabilizing cardiac membranes, making this the targeted complication for the prescribed treatment.
Choice C reason: Hypernatremia (high sodium) causes neurological symptoms like confusion, not muscle weakness or arrhythmias. The prescribed treatments do not address sodium levels; insulin and glucose manage potassium, and bicarbonate corrects acidosis. Hypernatremia is not a primary concern in acute renal failure with these symptoms.
Choice D reason: Hypokalemia (low potassium) causes muscle weakness and arrhythmias but is rare in acute renal failure, where hyperkalemia is typical due to reduced excretion. The prescribed treatments aim to lower potassium, not increase it, making hypokalemia an incorrect target for this therapy in the context of renal failure.

Correct Answer is D
Explanation
Choice A reason: Saying “I am not sure I follow you” seeks clarification, encouraging the patient to elaborate without dismissing their feelings. It fosters open communication, allowing the nurse to understand the patient’s concerns better, which supports therapeutic interaction and validates the patient’s emotional expression in a clinical setting.
Choice B reason: Noticing lip-biting acknowledges nonverbal cues, signaling the nurse’s attentiveness to the patient’s emotional state. This observation invites further discussion without judgment, promoting trust and validating the patient’s feelings, which is therapeutic and does not undermine or belittle their concerns in a mental health context.
Choice C reason: Stating “You appear tense” reflects observation of the patient’s emotional state, prompting exploration of underlying issues. It validates the patient’s feelings without dismissal, encouraging dialogue. This therapeutic approach supports emotional expression and does not belittle concerns, making it appropriate in a nurse-patient interaction.
Choice D reason: Saying “Everything will be alright” dismisses the patient’s concerns by offering false reassurance without addressing specific issues. This minimizes their emotional experience, potentially invalidating feelings and discouraging open communication, which can undermine trust and hinder therapeutic progress in managing mental health concerns.
Correct Answer is A
Explanation
Choice A reason: In ESRD, anuria means no urine output, so excess fluid accumulates in the body, increasing intravascular volume. This can cause hypertension, pulmonary edema, and respiratory distress. Educating the client about these risks emphasizes the importance of fluid restrictions to prevent life-threatening complications between dialysis sessions, addressing their frustration accurately.
Choice B reason: Advising increased fluid intake is incorrect for anuric ESRD patients, as their kidneys cannot excrete fluid. This would exacerbate fluid overload, leading to hypertension, heart failure, or pulmonary edema. Hydration is managed through dialysis, not increased oral intake, which could overwhelm the body’s limited fluid-handling capacity.
Choice C reason: Stating that fluid intake is unrestricted with dialysis is incorrect. Even with regular dialysis, excessive fluid intake between sessions can lead to overload, causing hypertension or pulmonary edema. Dialysis removes a limited amount of fluid per session, requiring strict restrictions to maintain safe fluid balance and prevent complications.
Choice D reason: While potassium and phosphorus restrictions are critical in ESRD to prevent hyperkalemia and hyperphosphatemia, the client’s question focuses on fluid restrictions. This response does not address fluid overload risks like hypertension or pulmonary edema, which are direct consequences of excessive fluid intake in anuric patients, making it irrelevant to the query.
