A nurse is collecting data from a client who is in renal failure. Which of the following findings should the nurse identify as a manifestation of hyperkalemia?

Choice A reason: Shoulder harnesses at shoulder level secure the infant, distributing crash forces evenly. Scientifically, this aligns with safety standards, preventing spinal injury by stabilizing the torso, a critical car seat feature per biomechanical crash studies for optimal protection.

Choice B reason: A cushion under the head risks airway obstruction or spinal misalignment in crashes. Scientifically, added padding alters manufacturer design, increasing injury risk, as car seats are engineered for direct fit without extras per safety regulations.

Choice C reason: A 90-degree angle is upright, risking airway collapse in newborns with weak necks. Scientifically, a 30-45-degree recline supports breathing and spinal alignment, making this unsafe per pediatric and crash safety evidence.

Choice D reason: Airbags in the front seat can fatally injure infants in rear-facing seats via rapid inflation. Scientifically, back-seat placement avoids this, as airbag force exceeds infant tolerance, contradicting safety mandates for car seat positioning.

Choice A reason: Fidelity is keeping promises and maintaining trust, as the nurse commits to walking daily with the client. This builds therapeutic reliability, reducing anxiety through consistent support, aligning with ethical standards where honoring commitments fosters psychological safety and strengthens the nurse-patient relationship scientifically.

Choice B reason: Justice involves fair resource distribution, not individual promises like walking with a client. This scenario focuses on personal commitment, not equity among patients. Ethically, justice applies to systemic fairness, lacking relevance to this specific supportive action grounded in trust-building principles.

Choice C reason: Nonmaleficence means avoiding harm, but promising to walk exceeds mere harm prevention, aiming to alleviate anxiety actively. While it supports well-being, it’s not the primary principle here. Scientifically, this is more about trust than just safety, distinguishing it from nonmaleficence’s core intent.

Choice D reason: Autonomy respects client decisions, but the nurse’s promise is her initiative, not the client’s choice. It supports, not directs, independence. Ethically, autonomy focuses on self-determination, whereas this action reflects commitment, making fidelity the more fitting principle in this scenario.
