HESI RN Exit Exam 2024 Quizlet

Correct Answer: C

Rationale: Before a CT scan with contrast, the nurse should review the serum creatinine level. This is crucial in assessing kidney function because contrast agents can potentially worsen renal function, leading to contrast-induced nephropathy. Monitoring serum creatinine helps in identifying patients at risk and taking necessary precautions. Serum potassium (Choice A) is important in conditions like hyperkalemia but is not the priority before a contrast CT scan. Blood urea nitrogen (BUN) (Choice B) is another renal function test but is not as specific as serum creatinine for assessing kidney function. Serum glucose (Choice D) is important in monitoring blood sugar levels, especially in diabetic patients, but it is not directly related to the risk of contrast-induced nephropathy in this scenario.

Correct Answer: A

Rationale: Oatmeal cookies are the best snack suggestion for a preschooler with constipation needing to increase fiber intake. Oatmeal is high in fiber, which helps relieve constipation. Cheese sticks, yogurt, and apple slices are not as high in fiber content as oatmeal and may not be as effective in addressing the constipation issue in this scenario.

Correct Answer: C

Rationale: The correct answer is C: Orthopnea. If the client is orthopneic, the nurse needs to adapt the insertion position that does not place the client in a supine position. This means the head of the bed should be elevated as much as possible to facilitate catheter insertion without compromising the client's breathing. High urinary pH (choice A) is not directly relevant to the insertion position of a urinary catheter. Abdominal ascites (choice B) may impact the procedure due to abdominal distension but is not as crucial as orthopnea. Fever (choice D) does not specifically affect the client's position for urinary catheter insertion.

Correct Answer: C

Rationale: The correct instruction for using a metered dose inhaler is to move the device one to two inches away from the mouth. This distance helps ensure effective delivery of the medication directly to the airways. Choice A is incorrect as the mouthpiece should be placed between the lips, not under the tongue. Choice B is incorrect because the device should be pressed down before breathing in, not after. Choice D is wrong because the patient should breathe out fully before using the inhaler, not while compressing the device.

Correct Answer: A

Rationale: The best response for the nurse to provide is that dialysis would need to be resumed if chronic rejection becomes a reality. Chronic rejection of a transplanted kidney can lead to kidney failure, necessitating the need for dialysis until another transplant is possible. Choice B is incorrect because although immunosuppressive therapy may be adjusted, the immediate concern is the potential need for dialysis. Choice C is incorrect because scheduling a second transplant immediately is not typically the first step following chronic rejection. Choice D is also incorrect as close monitoring of kidney function is essential but does not address the immediate need for dialysis if chronic rejection occurs.
