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: Bluntly stating unavailability dismisses the interrupting patient’s needs without offering a solution, potentially escalating distress. This approach lacks therapeutic communication, as it fails to acknowledge the patient’s urgency or provide a clear plan, which is critical in maintaining trust in a mental health setting.
Choice B reason: Ending the current session prematurely disrespects the silent patient’s therapeutic process. Silence may reflect processing or discomfort, requiring time to build trust. Abruptly shifting focus undermines the current patient’s care, potentially worsening their mental health and disrupting the therapeutic relationship.
Choice C reason: Inviting the interrupting patient to join violates confidentiality and disrupts the current patient’s safe space. Combining sessions without consent breaches ethical principles, potentially causing discomfort or mistrust, which hinders therapeutic progress for both patients in a mental health context.
Choice D reason: Acknowledging the interruption and scheduling a follow-up in 5 minutes respects both patients’ needs. It maintains the current patient’s therapeutic time while addressing the interrupting patient’s urgency, ensuring fairness and trust. This approach upholds ethical care and supports a therapeutic environment for mental health treatment.
Correct Answer is A
Explanation
Choice A reason: A 201 status indicates voluntary admission to a mental health facility, where the client can request discharge by signing a withdrawal form, typically with a 72-hour notice period. This matches the client’s statement, as voluntary patients retain control over their discharge, consistent with mental health laws.
Choice B reason: A 303 status involves extended involuntary commitment for ongoing treatment, typically after a court hearing. It does not allow self-initiated discharge by signing a form, as the client’s statement suggests, making this status incompatible with the described ability to request withdrawal.
Choice C reason: A 302 status is an involuntary commitment for imminent danger, requiring medical or legal approval for discharge, not a simple request form. The client’s ability to sign for withdrawal indicates voluntary status, making 302 incorrect for this scenario.
Choice D reason: A 301 status is not a standard term in mental health commitment laws (e.g., Pennsylvania’s Mental Health Procedures Act). The client’s ability to request discharge aligns with voluntary (201) status, not an undefined or involuntary category, making this option incorrect.
