A nurse is caring for a patient hospitalized with acute kidney injury (AKI). The healthcare provider has ordered daily weights and strict intake and output monitoring. The nurse notes that the patient has gained 3 pounds over the past 48 hours, with minimal urine output recorded during that time. What does this assessment finding most likely indicate?

Choice A reason: Ignoring sexually aggressive behavior is unsafe and unprofessional, as it fails to address potential escalation or harm. Aggression may stem from impulsivity or mental health conditions, requiring intervention to ensure safety and maintain therapeutic boundaries, making this response inadequate and risky in a behavioral health setting.

Choice B reason: Setting firm limits and boundaries establishes clear expectations, reducing inappropriate behavior while maintaining safety. This approach addresses the client’s impulsivity or lack of control, common in mental health disorders, by reinforcing professional conduct and ensuring a therapeutic environment, making it the most effective and safe response.

Choice C reason: Walking away and delegating care avoids addressing the behavior, potentially escalating the client’s aggression or disrupting care continuity. It fails to establish boundaries, which are critical for managing behavioral issues in mental health settings, and may undermine the client’s trust in the therapeutic process, making it inappropriate.

Choice D reason: Reporting to the director without first addressing the behavior skips essential de-escalation steps. While reporting may be needed for persistent issues, immediate boundary-setting is more appropriate to manage aggression, maintain safety, and support therapeutic goals, making this response less effective as an initial action.

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.
