Nursing Elites

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:

• 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.

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. 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. 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.

5. Which task for a patient with neutropenia is appropriate for the registered nurse (RN) to delegate to a licensed practical/vocational nurse (LPN/LVN)?

• A. Assessing the patient for signs and symptoms of infection
• B. Teaching the patient the purpose of neutropenic precautions
• C. Administering subcutaneous filgrastim (Neupogen) injection
• D. Developing a discharge teaching plan for the patient and family

Correct answer: C

Rationale: The correct answer is C because administering subcutaneous medications falls within the education and scope of practice of an LPN/LVN. Assessing the patient for signs and symptoms of infection, teaching the patient, and developing a discharge plan are tasks that require an RN level of education and scope of practice. LPN/LVNs can assist in patient care, but tasks that involve assessment, teaching, and care planning are typically the responsibility of an RN.
