1. Which assessment finding should the nurse caring for a patient with thrombocytopenia communicate immediately to the healthcare provider?
- A. The platelet count is 52,000/µL
- B. The patient is difficult to arouse
- C. There are purpura on the oral mucosa
- D. There are large bruises on the patient's back
Correct answer: B
Rationale: The correct answer is B. Difficulty in arousing the patient may indicate a cerebral hemorrhage, which is life-threatening and requires immediate action. While a low platelet count (choice A) is concerning in thrombocytopenia, it does not require immediate communication unless accompanied by active bleeding or other critical symptoms. Purpura on the oral mucosa (choice C) and large bruises on the patient's back (choice D) are important findings in thrombocytopenia but do not indicate an immediate life-threatening situation like a possible cerebral hemorrhage.
2. The complete blood count (CBC) indicates that a patient is thrombocytopenic. Which action should the nurse include in the plan of care?
- A. Avoid intramuscular injections.
- B. Encourage increased oral fluids.
- C. Check temperature every 4 hours.
- D. Increase intake of iron-rich foods.
Correct answer: A
Rationale: The correct action to include in the plan of care for a thrombocytopenic patient is to avoid intramuscular injections. Thrombocytopenia is a condition characterized by a decreased number of platelets, which are essential for blood clotting. Intramuscular injections can pose a risk of bleeding in patients with low platelet counts. Encouraging increased oral fluids (choice B) is beneficial for hydration but does not directly address the risk of bleeding associated with thrombocytopenia. Checking temperature every 4 hours (choice C) is important for monitoring infection but does not specifically address the risk of bleeding. Increasing intake of iron-rich foods (choice D) is more related to addressing anemia, not the primary concern of bleeding in thrombocytopenia.
3. 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.
4. Which patient should the nurse assign as the roommate for a patient who has aplastic anemia?
- A. A patient with chronic heart failure
- B. A patient who has viral pneumonia
- C. A patient who has right leg cellulitis
- D. A patient with multiple abdominal drains
Correct answer: A
Rationale: The correct answer is A because patients with aplastic anemia are at risk for infection due to low white blood cell production. Assigning a roommate with viral pneumonia (choice B), cellulitis (choice C), or multiple abdominal drains (choice D) could expose the patient with aplastic anemia to potential infectious agents, which could further compromise their health.
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:
- 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.
