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: 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.
