ATI Comprehensive Exit Exam

Correct Answer: A

Rationale: The correct answer is to obtain the specimen immediately upon the client waking up. Collecting sputum early in the morning provides the best sample for tuberculosis testing. Option B is incorrect because waiting a day can decrease the accuracy of the specimen. Option C is incorrect as it does not specify the optimal timing for specimen collection. Option D is incorrect as sterile gloves should be worn for infection control but do not specifically relate to the timing of specimen collection.

Correct Answer: C

Rationale: The correct action the nurse should take when administering a cleansing enema is to hold the container of the enema solution 61 cm (24 in) above the client. This height facilitates the proper flow of the solution into the client's rectum. Positioning the client on their left side helps facilitate the administration process, but it is not the specific action related to the enema solution. Inserting the enema tubing 8 cm (3.1 in) into the rectum is incorrect as it may not deliver the solution effectively. Advancing the enema tubing 15 cm (6 in) into the client's rectum is excessive and could cause trauma.

Correct Answer: D

Rationale: The correct answer is D, a history of allergy to shellfish. A known allergy to shellfish is a contraindication for the use of contrast media in a CT scan due to the potential risk of an allergic reaction, which could be severe and life-threatening. Choices A, B, and C are not contraindications to the procedure. A normal white blood cell count, urine specific gravity within the normal range, and a history of asthma do not typically interfere with the administration of contrast media for a CT scan.

Correct Answer: B

Rationale: The correct answer is B. Limiting potassium-rich foods is crucial for clients with chronic kidney disease to prevent hyperkalemia, a common complication. Increasing intake of potassium-rich foods like bananas (choice A), protein-rich foods (choice C), or dairy products (choice D) can exacerbate hyperkalemia in these clients. Bananas, protein-rich foods, and dairy products are all high in potassium, which is detrimental for individuals with chronic kidney disease. Therefore, choices A, C, and D are incorrect.

Correct Answer: A

Rationale: The correct instruction for a client prescribed nitroglycerin sublingual tablets is to lie down before taking the medication. Nitroglycerin can cause a sudden drop in blood pressure leading to dizziness or fainting, so taking the medication while lying down helps prevent falls. Choice B is incorrect because nitroglycerin is usually taken on an empty stomach to enhance its absorption. Choice C is incorrect as taking a double dose of nitroglycerin can lead to low blood pressure and other adverse effects. Choice D is incorrect as nitroglycerin sublingual tablets should be stored in their original container at room temperature away from light and moisture, not in the refrigerator.
