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?
Dry mucous membranes
Hyperactive reflexes
Trousseau's sign
Irregular heart rate
The Correct Answer is D
Choice A reason: Dry mucous membranes signal dehydration, not hyperkalemia directly. High potassium affects cardiac and nerve function, not mucosal hydration status in renal failure.
Choice B reason: Hyperactive reflexes occur in hypocalcemia, not hyperkalemia. Excess potassium depresses nerve and muscle activity, often reducing reflexes instead of enhancing them.
Choice C reason: Trousseau’s sign indicates hypocalcemia, with carpal spasm from cuff pressure. Hyperkalemia in renal failure doesn’t trigger this; it’s a calcium issue.
Choice D reason: Irregular heart rate, like bradycardia or arrhythmias, stems from hyperkalemia’s effect on cardiac conduction. In renal failure, potassium excess disrupts rhythms critically.

Correct Answer is B
Explanation
Choice A reason: Blaming assistive personnel is subjective and speculative, not factual documentation. Falls may have multiple causes—mobility or environment—not just slippers. Legally and scientifically, records require objective data, not assumptions, to ensure accurate care planning and avoid liability missteps in clinical reporting.
Choice B reason: Quoting the client’s account provides objective, firsthand data about the fall’s circumstances—loss of balance during transfer. This factual detail aids in assessing risk factors like mobility or weakness, aligning with scientific documentation standards for precision and relevance in medical records.
Choice C reason: Incident reports are separate from medical records; mentioning one here is inappropriate. It’s an administrative action, not clinical data, and risks redundancy. Scientifically, records focus on patient status, not process notes, ensuring clarity for care continuity over procedural documentation.
Choice D reason: "Does not appear" is vague, not definitive, lacking objective findings like "no bruising noted." Documentation requires specific observations for accuracy. Scientifically, imprecise language weakens care planning, as it fails to confirm injury status with measurable evidence needed for clinical decisions.
Correct Answer is D
Explanation
Choice A reason: Responding to family requires clinical judgment and communication skills beyond AP scope. Nurses handle this in mass casualty for accuracy.
Choice B reason: Triage prioritization needs nursing assessment skills, not AP training. Determining care order is a licensed responsibility in emergencies like this.
Choice C reason: Cleaning and dressing wounds involves sterile technique and assessment, outside AP scope. Nurses perform this in mass casualty settings.
Choice D reason: Taking vital signs is within AP scope, providing data for nurse triage. It’s a routine task, safely assigned in a mass casualty event.
