A nurse is providing care to a client who is preparing to undergo surgery. The client inquires about advance directives. Which of the following statements should the nurse make?

Choice A reason: Budesonide prevents, not rescues, asthma attacks; rescue inhalers like albuterol are used instead. This shows misunderstanding of its controller role in management.

Choice B reason: Rinsing after budesonide, a corticosteroid, prevents oral thrush by removing residue. This reflects correct understanding of side effect prevention in asthma therapy.

Choice C reason: Timing budesonide to meals and bedtime isn’t standard; it’s typically twice daily. This indicates confusion about its preventive, not situational, use.

Choice D reason: Pre-exercise use fits rescue inhalers, not budesonide, which builds long-term control. This misapplies its purpose, showing a lack of asthma management grasp.

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.
