The nurse is caring for a client with end-stage renal disease (ESRD) who is anuric and receives hemodialysis three times a week. During a routine assessment, the patient expresses frustration about strict fluid restrictions and states, “I don’t even make urine anymore, so why does it matter how much I drink?” Which of the following is the most appropriate response by the nurse?

Choice A reason: In the oliguric phase of AKI, kidney function is severely impaired, reducing potassium excretion. This leads to hyperkalemia, which disrupts cardiac electrical activity, potentially causing life-threatening arrhythmias or cardiac arrest. Elevated potassium levels are a hallmark of this phase due to decreased glomerular filtration rate and impaired tubular secretion.

Choice B reason: Urine output of 2000 mL in 24 hours indicates polyuria, characteristic of the recovery phase of AKI, not the oliguric phase, where output is typically less than 400 mL/day. High urine output suggests restored renal function, which is not expected in the oliguric phase, where kidneys fail to filter adequately.

Choice C reason: Tachycardia may occur in AKI due to fluid overload causing increased cardiac workload or electrolyte imbalances like hyperkalemia affecting heart rhythm. However, it is a secondary symptom and less specific than hyperkalemia, which directly results from impaired renal excretion and poses a more immediate risk to cardiac function.

Choice D reason: Tenting of the skin indicates dehydration, which may precede AKI but is not typical in the oliguric phase, where fluid retention is more common due to reduced urine output. Fluid overload leads to edema, not dehydration, making skin tenting an unlikely finding in this phase of AKI.

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.
