1. A 44-year-old with sickle cell anemia who says his eyes always look sort of yellow
- A. A 23-year-old with no previous health problems who has a nontender lump in the axilla
- B. A 50-year-old with early-stage chronic lymphocytic leukemia who reports chronic fatigue
- C. A 19-year-old with hemophilia who wants to learn to self-administer factor VII replacement
- D. A 44-year-old with sickle cell anemia who says his eyes always look sort of yellow
Correct answer: B
Rationale: Choice B is the correct answer because the scenario describes a 50-year-old with early-stage chronic lymphocytic leukemia who presents with chronic fatigue. Chronic lymphocytic leukemia commonly presents with symptoms like fatigue, weight loss, and enlarged lymph nodes. The other choices are less likely as they do not match the clinical presentation described in the scenario. Choice A describes a 23-year-old with a nontender lump in the axilla, which is more suggestive of a benign condition like a lipoma. Choice C describes a 19-year-old with hemophilia who wants to learn to self-administer factor VII replacement, which is unrelated to the symptoms of chronic lymphocytic leukemia. Choice D repeats the scenario, which is not relevant in selecting the appropriate answer.
2. A patient who has immune thrombocytopenic purpura (ITP) has an order for a platelet transfusion. Which information indicates that the nurse should consult with the healthcare provider before obtaining and administering platelets?
- A. Platelet count is 42,000/µL
- B. Petechiae are present on the chest
- C. Blood pressure (BP) is 94/56 mm Hg
- D. Blood is oozing from the venipuncture site
Correct answer: A
Rationale: The correct answer is A. Platelet transfusions are not usually indicated until the platelet count is below 10,000 to 20,000/µL unless the patient is actively bleeding. In this scenario, the platelet count of 42,000/µL is not significantly low to warrant a platelet transfusion without active bleeding. Consulting with the healthcare provider is essential before giving the transfusion to ensure the appropriateness of the treatment. Choices B, C, and D are not directly related to the need for consulting before a platelet transfusion. Petechiae, low blood pressure, and oozing from the venipuncture site are common findings in patients with ITP and may not necessarily contraindicate a platelet transfusion at this platelet count.
3. A patient is considering options to manage his/her coronary artery disease. The nurse explains a coronary artery bypass graft procedure will:
- A. Cure the patient's coronary artery disease.
- B. Replace the leaking valve in the heart.
- C. Connect grafts to aorta to improve blood flow.
- D. Place a permanent pacemaker on the heart muscle.
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.
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 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.
