Evolve HESI Medical Surgical Practice Exam Quizlet

Correct Answer: A

Rationale: A serum potassium level of 2.5 mEq/L is critically low, indicating severe hypokalemia. The immediate action the nurse should take is to inform the healthcare provider of the need for potassium replacement. Option B, preparing to administer glucose-insulin-potassium replacement, is not the first-line intervention; it may be considered in specific situations but requires a healthcare provider's prescription. Option C, changing the plan of care to include hourly urinary output measurement, is not the priority when managing critically low potassium levels. Option D, instructing the client to increase daily intake of potassium-rich foods, is not appropriate in this acute situation where immediate intervention is needed to address the dangerously low potassium level.

Correct Answer: C

Rationale: Before transporting the client for whirlpool therapy to debride the burned area, the nurse should give a prescribed narcotic analgesic agent. This intervention is essential to manage pain effectively during the debridement process. Obtaining supplies to re-dress the burn area (Choice A) is important but not as immediate as providing pain relief. Verifying the client's signed consent form (Choice B) is necessary for procedures but does not address the client's immediate pain needs. Performing active range-of-motion exercises (Choice D) is not indicated before whirlpool therapy for debridement of burns and may cause further discomfort to the client.

Correct Answer: A

Rationale: The correct answer is A. Learning is best demonstrated by a change in behavior. A client who can safely and correctly perform the procedure shows they have acquired the skill. Choice B is incorrect because critiquing the nurse's performance does not directly demonstrate the client's ability to perform the procedure. Choice C is incorrect because explaining the steps does not guarantee the client can physically perform the injection. Choice D is incorrect as answering a posttest only assesses theoretical knowledge, not practical application.

The immediate action the nurse should take is to inform the healthcare provider of the need for potassium replacement. Option B, preparing to administer glucose-insulin-potassium replacement, is not the first-line intervention; it may be considered in specific situations but requires a healthcare provider's prescription.

Option D, instructing the client to increase daily intake of potassium-rich foods, is not appropriate in this acute situation where immediate intervention is needed to address the dangerously low potassium level.

Correct Answer: D

Rationale: In this scenario, the most crucial instruction for the nurse to provide is to take the client to the emergency department (ED). Missing dialysis can lead to severe complications in clients with chronic kidney disease, such as electrolyte imbalances and fluid overload. Lethargy and difficulty in arousing the client suggest a critical situation that requires immediate medical attention. Applying home oxygen, checking the dialysis access site, and ensuring salt intake avoidance, although important, are not as urgent as seeking emergency care to address the potential severe complications from missed dialysis.
