ATI Perfusion Questions

1. A patient is considering options to manage his/her coronary artery disease. The nurse explains a coronary artery bypass graft procedure will:

Correct answer: C

Rationale: The correct answer is C. A coronary artery bypass graft procedure involves connecting grafts to the aorta to improve blood flow to the heart muscle by bypassing blocked or narrowed coronary arteries. This procedure does not cure coronary artery disease but helps improve blood supply to the heart. Choices A, B, and D are incorrect because a bypass graft procedure does not cure the underlying disease, replace heart valves, or involve the placement of a pacemaker.

2. Which collaborative problem will the nurse include in a care plan for a patient admitted to the hospital with idiopathic aplastic anemia?

Correct answer: B

Rationale: The correct answer is B: Potential complication: infection. Patients with idiopathic aplastic anemia have pancytopenia, which puts them at a high risk for infections due to decreased production of all blood cells (red blood cells, white blood cells, and platelets). Infection is a significant concern in these patients. Choices A, C, and D are incorrect because seizures, neurogenic shock, and pulmonary edema are not typically associated with idiopathic aplastic anemia. While seizures can occur in some conditions that affect the brain, neurogenic shock is related to spinal cord injury, and pulmonary edema is more commonly seen in conditions like heart failure.

3. 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.

4. The nurse is caring for a patient who 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: 'Wash hands regularly and avoid individuals who are ill.' After a splenectomy, the patient is at an increased risk of infection, particularly from gram-positive bacteria. Proper hand hygiene and avoiding contact with sick individuals are crucial to prevent infections. Choices A, B, and C are incorrect because checking for swollen lymph nodes, watching for excessive bleeding or bruising, and taking iron supplements are not specifically related to the increased infection risk post-splenectomy.

5. 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.
