Nursing Elites

1. 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.

2. After a patient with pancytopenia undergoes a bone marrow aspiration from the left posterior iliac crest, which action would be important for the nurse to take?

• A. Elevate the head of the bed to 45 degrees.
• B. Have the patient lie on the left side for 1 hour.
• C. Apply a sterile 2-inch gauze dressing to the site.
• D. Use a half-inch sterile gauze to pack the wound.

Correct answer: B

Rationale: After a bone marrow aspiration, it is important to have the patient lie on the left side for 30 to 60 minutes to decrease the risk of bleeding. Elevating the head of the bed to 45 degrees does not directly address the risk of bleeding. Applying a sterile 2-inch gauze dressing to the site is important for wound care but does not specifically address post-procedural positioning. Using a half-inch sterile gauze to pack the wound is not necessary after a bone marrow aspiration.

3. 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.

4. An appropriate nursing intervention for a patient with non-Hodgkin's lymphoma whose platelet count drops to 18,000/µL during chemotherapy is to

• A. check all stools for occult blood
• B. encourage fluids to 3000 mL/day
• C. provide oral hygiene every 2 hours
• D. check the temperature every 4 hours

Correct answer: A

Rationale: The correct answer is to check all stools for occult blood. With a platelet count of 18,000/µL, the patient is at a high risk of spontaneous bleeding. Checking stools for occult blood can help detect any internal bleeding early. Encouraging fluids and providing oral hygiene are important interventions in general, but in this case, monitoring for bleeding takes precedence. Checking the temperature every 4 hours is not directly related to the patient's current condition and platelet count.

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.
