HESI RN CAT Exit Exam

Correct Answer: C

Rationale: Administering the scheduled dose of furosemide is appropriate when a client with heart failure has an elevated BNP level. BNP elevation indicates fluid overload, and furosemide is a diuretic that helps in reducing excess fluid. Measuring the client's oxygen saturation (Choice A) is not directly related to addressing fluid overload. Administering nitroglycerin (Choice B) is not indicated for managing elevated BNP levels. Holding the furosemide dose (Choice D) would delay appropriate treatment for fluid overload.

Correct Answer: B

Rationale: The correct answer is B: 'It prevents the blood from clotting.' Warfarin works by inhibiting the synthesis of vitamin K-dependent clotting factors in the liver, thereby preventing the formation of blood clots. Choice A is incorrect because warfarin does not dissolve existing blood clots but prevents new ones from forming. Choice C is partially correct but not as specific as choice B in explaining how warfarin works. Choice D is unrelated to the mechanism of action of warfarin and is incorrect.

Correct Answer: A

Rationale: In this scenario, the nurse should first apply a sterile saline dressing to the wound. This action helps prevent infection and keeps the wound moist, which is crucial in promoting healing. Option B, notifying the healthcare provider, is important but should come after providing immediate wound care. Option C, administering pain medication, is not the priority when there is a small amount of bowel protruding from the wound. Option D, covering the wound with an abdominal binder, is not appropriate for this situation as it does not address the protruding bowel and potential risk for infection.

Correct Answer: A

Rationale: The correct answer is A because a client with a stable infection requires less supervision and is suitable for the new nurse. Choice B involves insulin administration for a client with poorly controlled diabetes, which may require more experience and supervision. Choice C involves a newly admitted patient with a head injury who requires frequent assessments, indicating a need for close monitoring. Choice D involves a patient receiving IV heparin, which requires precise monitoring and adjustment based on protocol, making it a higher-risk assignment for a new nurse without close supervision.

Correct Answer: C

Rationale: The correct answer is C: 'The full thickness burn has destroyed the nerves.' In full thickness burns, also known as third-degree burns, the nerve endings are destroyed, leading to a lack of pain sensation at the site of the burn. The description of the burn as dry, waxy, and white indicates a full thickness burn. Choices A, B, and D are incorrect because they do not explain the absence of pain in full thickness burns. Choice A is incorrect as a full-thickness burn involves significant tissue destruction. Choice B is incorrect because nerve compression would not explain the lack of pain in this context. Choice D is incorrect because second-degree burns, unlike full-thickness burns, are painful due to nerve endings being intact.
