ATI RN Comprehensive Exit Exam

Correct Answer: D

Rationale: A glomerular filtration rate of 14 mL/min indicates severe kidney impairment and the need for hemodialysis. The other choices, such as BUN 16 mg/dL, serum magnesium 1.8 mg/dL, and serum phosphorus 4.0 mg/dL, are within normal ranges and do not directly indicate the need for hemodialysis in chronic kidney disease.

Correct Answer: B

Rationale: The correct answer is B: Tachycardia. Tachycardia can indicate a hemolytic transfusion reaction, a severe and life-threatening complication of blood transfusion. The nurse should report tachycardia immediately to prevent further complications. Low back pain, flushed skin, and headache are also important to monitor during a blood transfusion, but they are not as indicative of a severe transfusion reaction as tachycardia.

Correct Answer: A

Rationale: The most crucial nursing action for a patient post-surgery is to monitor vital signs. Monitoring vital signs helps in detecting early signs of complications such as hemorrhage, shock, or infection. While monitoring the surgical site is important for assessing wound healing and signs of infection, it is secondary to monitoring vital signs. Checking blood pressure and oxygen saturation are also important, but they are components of monitoring vital signs.

Correct Answer: C

Rationale: An INR of 2.5 indicates a therapeutic level for a patient on warfarin. The INR (International Normalized Ratio) is the most accurate way to monitor and adjust warfarin doses. An INR of 1.1 (Choice A) is below the therapeutic range, indicating a need for an increased dose. PT (Prothrombin Time) of 12 seconds (Choice B) is not specific for warfarin therapy monitoring. Platelet count (Choice D) is not directly related to monitoring warfarin therapy.

Correct Answer: B

Rationale: The correct instruction for a client prescribed levothyroxine is to take the medication at the same time every day. This consistency is important for maintaining stable thyroid hormone levels. Choice A is incorrect because levothyroxine should be taken on an empty stomach to ensure proper absorption. Choice C is important but not directly related to the administration of levothyroxine. Choice D is incorrect as antacids can interfere with the absorption of levothyroxine.
