The nurse is caring for a client who is in the oliguric phase of acute kidney injury (AKI). During this phase of AKI, the nurse might anticipate which of the following findings?
Hyperkalemia
Urine output of 2000 mL in 24 hours
Tachycardia
Tenting of the skin
The Correct Answer is A
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.

Correct Answer is D
Explanation
Choice A reason: Assault involves threatening harm, not applicable here, as the issue is failure to document assessments, not intentional threats by staff. The client’s self-harm resulted from inadequate monitoring, not a staff-initiated threat, making assault an incorrect legal issue in this scenario.
Choice B reason: Battery involves unauthorized physical contact, not relevant to failure to document assessments. The client’s self-harm stemmed from inadequate observation, not staff-inflicted harm, making battery an inappropriate legal claim compared to negligence in monitoring and documentation.
Choice C reason: Suicide risk is a clinical concern, not a legal issue to defend against. While the client’s self-harm indicates risk, the hospital’s liability arises from failure to follow monitoring protocols, not the risk itself, making this option incorrect for the legal defense context.
Choice D reason: Malpractice involves negligence, such as failing to document hourly assessments for a high-risk client, leading to harm. This breach of standard care (1:1 observation) allowed self-harm, making the hospital liable for not adhering to protocols, requiring defense against malpractice for inadequate monitoring and documentation.
Correct Answer is C
Explanation
Choice A reason: Neighborhood watch programs enhance community safety but do not directly address mental health needs. They lack therapeutic components to manage symptoms or prevent decompensation, which are critical for preventing readmission in clients with mental health disorders, making this factor less relevant to sustained community stability.
Choice B reason: Taking meals at a food bank addresses nutritional needs but does not directly support mental health stability. While nutrition is important, it does not provide the therapeutic interventions or coping strategies needed to manage mental health disorders and prevent relapse or hospital readmission.
Choice C reason: Participation in treatment, such as therapy or medication adherence, directly addresses mental health symptoms, improving coping skills and emotional regulation. Consistent treatment reduces relapse risk, enhances stability, and supports community integration, making it the most effective factor for preventing readmission in clients with mental health disorders.
Choice D reason: A safe living environment reduces stress and safety risks but is secondary to active treatment. Without ongoing therapy or medication, environmental safety alone cannot manage symptoms or prevent decompensation, making it less critical than treatment participation for maintaining community stability and avoiding readmission.
