HESI RN CAT Exit Exam 1

Correct Answer: C

Rationale: Centralized cyanosis and tachycardia are classic signs of congenital heart disease. Choice A is incorrect because cyanosis in the hands and feet is not specific to congenital heart disease. Choice B is incorrect as the vital signs provided are not specific indicators of congenital heart disease. Choice D is unrelated to the typical signs of congenital heart disease.

Correct Answer: D

Rationale: Successful extubation relies on the patient's ability to maintain an effective breathing pattern. This indicates that the patient can adequately oxygenate and ventilate without the need for mechanical support. Monitoring tissue perfusion, preventing infection, and ensuring safety are important but not directly related to the immediate criteria for successful extubation. Tissue perfusion, injury prevention, and infection control are crucial aspects of overall patient care but are not the primary factors to consider when evaluating readiness for extubation.

Correct Answer: C

Rationale: The correct answer is C because a fast heart rate and jitteriness are common side effects of bronchodilators like albuterol. Choice A is incorrect as nervousness is more likely a side effect of the medication than solely related to hypoxia. Choice B is incorrect as it provides a partial explanation focusing only on tremors and heart rate, not mentioning jitteriness. Choice D is incorrect because excessive coughing and tachypnea are not typically associated with bronchodilator use; instead, they may indicate inadequate relief or other issues.

Correct Answer: C

Rationale: The correct response is to encourage the client to perform breast self-examination (BSE) 2 to 3 days after her menstrual period ends. This timing is important because breasts are least tender during this phase of the menstrual cycle, allowing for a more effective examination. Choice A is incorrect because while scheduling an annual mammogram is important, the immediate concern is the timing of BSE. Choice B is incorrect as the client's BSE practice just needs a slight adjustment in timing, not an in-depth review. Choice D is incorrect as the client should perform BSE when her breasts are least tender for optimal detection of any abnormalities.

Correct Answer: C

Rationale: The correct answer is C. Clients in renal failure are at high risk for hypomagnesemia due to their impaired kidney function. Renal failure can lead to decreased excretion of magnesium, resulting in its buildup in the body and potential hypomagnesemia. This client requires careful nursing assessment for signs and symptoms of hypomagnesemia to prevent complications. Choices A, B, and D are not as directly associated with renal failure and its impact on magnesium levels. Intractable vomiting, hyperparathyroidism, and excessive consumption of simple carbohydrates may have other health implications but are not as strongly linked to hypomagnesemia as renal failure.
