ATI Perfusion Questions
1. The nurse is caring for a patient post coronary artery bypass graft who rates his/her pain as an 8 out of 10 on the subjective pain scale. Should the nurse choose to administer morphine sulfate intravenously as it has benefits to cardiac patients (select one that does not apply)?
- A. Decreasing myocardial oxygen supply
- B. Decreasing myocardial oxygen consumption
- C. Decreasing heart rate
- D. Increasing blood pressure
Correct answer: D
Rationale: Morphine sulfate, a potent opioid analgesic, can cause vasodilation leading to a decrease in blood pressure rather than an increase. Choice A is incorrect as morphine can decrease myocardial oxygen consumption by reducing the workload of the heart. Choice B is incorrect as morphine can decrease heart rate as a side effect. Choice C is incorrect as morphine typically decreases blood pressure rather than increasing it.
2. The nurse notes scleral jaundice in a patient being admitted with hemolytic anemia. The nurse will plan to check the laboratory results for the
- A. Schilling test
- B. bilirubin level
- C. gastric analysis
- D. stool occult blood
Correct answer: B
Rationale: The correct answer is B: bilirubin level. Jaundice, characterized by scleral jaundice, is caused by the elevation of bilirubin levels associated with red blood cell hemolysis. Checking the bilirubin level in the laboratory results will help assess the severity of jaundice in the patient. Choices A, C, and D are incorrect because the Schilling test is used to assess vitamin B12 absorption, gastric analysis is used to evaluate gastric function, and stool occult blood is used to detect hidden blood in the stool, which are not directly related to evaluating jaundice in a patient with hemolytic anemia.
3. The nurse reviews the laboratory test results of a patient admitted with abdominal pain. Which information will be most important for the nurse to communicate to the health care provider?
- A. Monocytes 4%
- B. Hemoglobin 13.6 g/dL
- C. Platelet count 168,000/μL
- D. White blood cell (WBC) count 15,500/μL
Correct answer: A
Rationale: The correct answer is A. A low percentage of monocytes can indicate a viral infection. This is crucial information to communicate as it suggests a specific type of infection that may require targeted treatment. Choices B, C, and D do not directly relate to an infectious process and are within normal ranges, so they are not as urgent to communicate to the healthcare provider in this context.
4. 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:
- A. Decreasing myocardial oxygen supply.
- B. Increasing preload.
- C. Decreasing cardiac output.
- D. Decreasing afterload.
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.
5. The nurse assesses a patient who has numerous petechiae on both arms. Which question should the nurse ask the patient?
- A. Are you taking any oral contraceptives?
- B. Have you been prescribed antiseizure drugs?
- C. Do you take medication containing salicylates?
- D. How long have you been taking antihypertensive drugs?
Correct answer: C
Rationale: The correct answer is C: 'Do you take medication containing salicylates?' Petechiae are tiny, pinpoint, red or purple spots on the skin due to bleeding under the skin. Salicylates, which are found in medications like aspirin, interfere with platelet function and can lead to petechiae and ecchymoses. Asking about salicylate-containing medications is crucial in this situation. Choices A, B, and D are incorrect because they are not directly related to the development of petechiae.
