ATI Exit Exam 2023 Quizlet

Correct Answer: A

Rationale: The correct answer is A. Children with varicella are contagious until the vesicles crust over, which is important for preventing transmission. Choice B is incorrect as varicella and herpes zoster are caused by different viruses, so the varicella vaccine is given to prevent varicella, not herpes zoster. Choice C is incorrect because varicella is primarily spread through respiratory secretions, so airborne precautions are recommended, not droplet precautions. Choice D is incorrect as children with varicella are contagious even before the first vesicle eruption, not just 4 days before.

Correct Answer: D

Rationale: Placing a pillow under the client's lower legs is the correct intervention because it helps prevent pressure on the incision site and promotes circulation. Elevating the lower legs also aids in reducing swelling and improving blood flow. Applying heat to the incision site (Choice A) is contraindicated in the early postoperative period as it can increase inflammation and the risk of infection. Keeping the client's knee flexed while in bed (Choice B) may lead to contractures or limited extension of the knee joint. Placing a pillow under the client's knee (Choice C) may cause hyperextension of the knee, which is also not recommended post knee arthroplasty.

Correct Answer: C

Rationale: Furosemide can cause low potassium levels, and clients should be advised to rise slowly to prevent dizziness.

Correct Answer: A

Rationale: The correct answer is A. Clozapine can cause agranulocytosis, a serious condition that decreases the number of white blood cells. Reporting a sore throat is crucial as it could be a sign of infection. Choice B is incorrect because there is no specific interaction between clozapine and grapefruit juice. Choice C is incorrect because clozapine is usually taken without regard to meals. Choice D is incorrect as clozapine is generally taken without food to enhance absorption.

Correct Answer: C

Rationale: Cheddar cheese is an excellent source of calcium, which is essential for bone health. Calcium helps strengthen bones and reduces the risk of osteoporosis. Broccoli (choice A) is also a good source of calcium but not as high as cheddar cheese. Bananas (choice B) and whole wheat bread (choice D) do not provide significant amounts of calcium and are not as effective in preventing osteoporosis as cheddar cheese.
