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: The right to do no harm (nonmaleficence) is an ethical principle, not a specific client right. While premature restraints may cause harm, this option does not directly address the legal right violated, which is the use of least restrictive interventions, making it less precise.

Choice B reason: Informed consent involves agreeing to treatments, not the use of restraints, which is a safety intervention. While clients should be informed, premature restraint use violates the right to least restrictive care, not consent, as restraints are not typically consensual interventions.

Choice C reason: Confidential and respectful care relates to privacy and dignity, not the method of intervention. Premature restraints violate the principle of using less invasive options first, not confidentiality or respect, making this right irrelevant to the specific violation described in the scenario.

Choice D reason: The right to least restrictive treatment requires using non-invasive interventions (e.g., de-escalation) before restraints. Premature restraint use violates this right, as mental health laws mandate the least coercive measures to ensure safety, prioritizing patient autonomy and minimizing harm, making this the correct answer.

Choice A reason: Taking blood pressure in the left arm with an AV fistula risks compressing the fistula, potentially causing thrombosis or damage. This can impair dialysis access, leading to inadequate treatment and complications like uremia or fluid overload. Blood pressure should be measured in the opposite arm to protect the fistula.

Choice B reason: Keeping the AV fistula site dry is important to prevent infection, as moisture can promote bacterial growth. However, it is not the priority over ensuring fistula patency, which is critical for effective dialysis. Infection prevention is secondary to confirming the fistula’s functionality to avoid life-threatening dialysis interruptions.

Choice C reason: Wrapping the AV fistula in gauze is not standard practice unless post-surgical or infected. Excessive wrapping may obscure the site, hindering patency assessments, and could increase infection risk if not changed properly. This action is less critical than ensuring the fistula’s functionality for dialysis.

Choice D reason: Assessing the AV fistula for bruit (whooshing sound) and thrill (vibration) confirms patency, ensuring it is functional for dialysis. A non-patent fistula prevents effective toxin and fluid removal, leading to uremia, hyperkalemia, or fluid overload. This assessment is the priority to ensure life-sustaining dialysis can proceed without complications.
