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 C
Explanation
Choice A reason: Informing the client about potential nurse reprimands is coercive and inappropriate, as it prioritizes the nurse’s interests over patient autonomy. This approach fails to explore the client’s reasons for refusal, which may involve side effects or mistrust, and does not support therapeutic communication or ethical care.
Choice B reason: Documenting refusal is necessary but not the first action. Exploring the reason for refusal allows the nurse to address concerns, potentially resolving issues like misunderstanding or side effects. Documentation follows after attempts to understand and educate, ensuring a therapeutic approach before recording the refusal.
Choice C reason: Asking the reason for refusal respects autonomy and initiates therapeutic communication. It identifies barriers like side effect fears or lack of understanding, enabling education or alternative solutions. This approach aligns with patient-centered care, addressing underlying issues to promote adherence while respecting the client’s rights.
Choice D reason: Stating that refusal is not permitted is coercive and violates autonomy. Clients have the right to refuse medication unless under involuntary treatment orders. This approach damages trust, escalates resistance, and contradicts ethical principles, making it an inappropriate initial response to medication refusal.
Correct Answer is C
Explanation
Choice A reason: Hourly nursing assessments are important for monitoring safety in restraints but are not the primary legal requirement. Assessments ensure no physical harm, but psychiatric evaluation within one hour is mandated to confirm restraint necessity, making this option secondary in priority for immediate post-restraint protocol.
Choice B reason: Constant supervision may be used, but transitioning to video monitoring after one hour does not meet strict regulatory standards for restraints. Face-to-face psychiatric evaluation within one hour is required to assess ongoing need and ensure patient rights, making this option less accurate for legal compliance.
Choice C reason: Regulatory standards (e.g., CMS, Joint Commission) mandate a face-to-face evaluation by a psychiatrist within one hour of initiating restraints to assess necessity, safety, and alternatives. This ensures compliance with mental health laws, protects patient rights, and prevents overuse, making it the required action.
Choice D reason: Reviewing restraint appropriateness hourly is part of ongoing care but is not the primary requirement. A psychiatrist’s face-to-face evaluation within one hour takes precedence to ensure legal and ethical use, as it confirms the clinical justification for restraints, making this option secondary.
