ATI Perfusion Questions

1. The nurse is caring for a patient post-coronary artery bypass graft procedure who is on a nitroglycerin intravenous drip. The nurse understands the importance of nitroglycerin with this procedure as:

Correct answer: D

Rationale: Nitroglycerin is a vasodilator that works by decreasing afterload, which is the pressure the heart must work against to eject blood during systole. By reducing afterload, nitroglycerin helps the heart pump more effectively and decreases the workload on the heart. This results in improved cardiac output and decreased myocardial oxygen demand. Choices A, B, and C are incorrect because nitroglycerin does not decrease myocardial oxygen supply, increase preload, or decrease cardiac output.

2. A patient who had a total hip replacement had an intraoperative hemorrhage 14 hours ago. Which laboratory test result would the nurse expect?

Correct answer: C

Rationale: The correct answer is C: Elevated reticulocyte count. Hemorrhage leads to the release of reticulocytes (immature red blood cells) from the bone marrow into circulation as a compensatory mechanism to replenish lost red blood cells. This response helps in restoring the oxygen-carrying capacity of the blood. Choices A and B, hematocrit of 46% and hemoglobin of 13.8 g/dL, may not reflect the immediate response to hemorrhage within 14 hours. Choice D, decreased white blood cell (WBC) count, is not directly related to the body's response to hemorrhage.

3. A patient in the emergency department complains of back pain and difficulty breathing 15 minutes after a transfusion of packed red blood cells is started. The nurse's first action should be to

Correct answer: D

Rationale: The patient's symptoms, back pain, and difficulty breathing after the transfusion indicate a possible acute hemolytic reaction, a severe transfusion reaction. The priority action in this situation is to discontinue the transfusion immediately to prevent further complications. Infusing normal saline helps maintain the patient's intravascular volume and prevent renal damage. Administering oxygen or obtaining a urine specimen is not the most urgent action and could delay essential treatment. Notifying the healthcare provider is important but should come after ensuring the patient's safety by stopping the blood transfusion.

4. A patient is being discharged after an emergency splenectomy following a motor vehicle crash. Which instructions should the nurse include in the discharge teaching?

Correct answer: D

Rationale: The correct answer is D. After a splenectomy, the patient is at an increased risk of infection, particularly from gram-positive bacteria. Washing hands and avoiding contact with individuals who are ill are crucial to reduce this risk. Choice A is incorrect because checking for swollen lymph nodes is not a priority after a splenectomy. Choice B is incorrect as while bleeding is a concern, it is more immediate post-operatively. Choice C is incorrect as iron supplements do not specifically relate to the risk of infection post-splenectomy.

5. During a physical assessment, the nurse examines the lymph nodes of a patient. Which assessment finding would be of most concern to the nurse?

Correct answer: A

Rationale: The correct answer is A. A 2-cm nontender supraclavicular node is of most concern because enlarged and nontender nodes in this area are highly suggestive of malignancies such as lymphoma. Choice B is less concerning as a 1-cm mobile and nontender axillary node is usually benign. Choice C, an inability to palpate any superficial lymph nodes, could be due to factors like obesity or edema, but it is not necessarily a cause for immediate concern. Choice D, firm inguinal nodes in a patient with an infected foot, may indicate a local reaction to infection rather than a systemic issue related to malignancy.
