ATI Exit Exam 180 Questions Quizlet

Correct Answer: B

Rationale: The correct action to prevent an air embolism in a client with a central venous catheter is to have the client perform the Valsalva maneuver while the catheter is removed. This maneuver helps to close the airway and prevent air from entering the bloodstream. Keeping the catheter clamped at all times (Choice A) is not necessary and may lead to clot formation. Using a non-coring needle (Choice C) is important for accessing the catheter but does not specifically prevent air embolism. Flushing the catheter with 0.9% sodium chloride (Choice D) helps maintain patency but does not directly prevent air embolism.

Correct Answer: B

Rationale: The correct answer is B. Clients taking metoprolol should regularly check their pulse and should not take the medication if their pulse is too low. Option A is incorrect because metoprolol should not be taken with a glass of milk. Option C is incorrect because stopping medication abruptly can be harmful. Option D is incorrect because antacids should not be taken with metoprolol as they can decrease its absorption.

Correct Answer: A

Rationale: In osteoarthritis, joint pain that improves with rest is a common characteristic due to the relief obtained by reducing weight-bearing on the affected joint. Joint stiffness that improves with movement is more indicative of rheumatoid arthritis, not osteoarthritis. Red, warm joints are typically seen in inflammatory arthritis conditions like rheumatoid arthritis, while systemic inflammation is not a primary feature of osteoarthritis.

Correct Answer: D

Rationale: The correct answer is D. Black, tarry stools can indicate gastrointestinal bleeding, a serious adverse effect of warfarin that requires immediate medical attention. Option A is incorrect because while bruising is a common side effect of warfarin, it is not limited to the elbows. Option B is incorrect as a red rash is not a typical adverse effect of warfarin. Option C is also incorrect because developing a cough is not a reason to discontinue warfarin unless advised by a healthcare provider.

Correct Answer: D

Rationale: The correct answer is D: Decreased deep tendon reflexes. In myasthenia gravis, muscle weakness is a common manifestation, leading to decreased deep tendon reflexes. Bradycardia (choice A) is not typically associated with myasthenia gravis. Increased muscle strength (choice B) is unlikely as muscle weakness is a hallmark of this condition. Diarrhea (choice C) is not a typical finding in myasthenia gravis.
