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. Which patient requires the most rapid assessment and care by the emergency department nurse?

Correct answer: B

Rationale: The correct answer is B because a neutropenic patient with a fever is at high risk for developing sepsis. Sepsis can progress rapidly and lead to life-threatening complications. Immediate assessment, obtaining cultures, and initiating antibiotic therapy are essential in this situation. Choices A, C, and D do not present with the same level of urgency as a neutropenic patient with a fever. Abdominal pain in a hemochromatosis patient, oozing gums after a tooth extraction in a thrombocytopenic patient, and nausea and diarrhea in a patient with sickle cell anemia, while concerning, do not indicate the same immediate risk of sepsis as a neutropenic patient with a fever.

3. 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.

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. 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.
