Nursing Elites

1. The nurse notes pallor of the skin and nail beds in a newly admitted patient. The nurse should ensure that which laboratory test has been ordered?

• A. Platelet count
• B. Neutrophil count
• C. Hemoglobin level
• D. White blood cell count

Correct answer: C

Rationale: The correct answer is C, 'Hemoglobin level.' Pallor of the skin and nail beds is a sign of anemia, which is characterized by a low hemoglobin level. Anemia is a condition where there is a decreased number of red blood cells or hemoglobin in the blood, leading to reduced oxygen-carrying capacity. Checking the hemoglobin level would help confirm the presence and severity of anemia, guiding further diagnostic and treatment interventions. Choices A, B, and D are incorrect because platelet count, neutrophil count, and white blood cell count are not typically associated with the pallor of the skin and nail beds, which are more indicative of an underlying anemic condition.

2. 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.

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. Which laboratory test will the nurse use to determine whether filgrastim (Neupogen) is effective for a patient with acute lymphocytic leukemia who is receiving chemotherapy?

• A. Platelet count
• B. Reticulocyte count
• C. Total lymphocyte count
• D. Absolute neutrophil count

Correct answer: D

Rationale: The correct answer is D, Absolute neutrophil count. Filgrastim (Neupogen) works by stimulating the production and function of neutrophils. Therefore, monitoring the Absolute neutrophil count is crucial to assess the effectiveness of filgrastim in increasing neutrophil levels. Choices A, B, and C are incorrect because platelet count, reticulocyte count, and total lymphocyte count do not directly reflect the effectiveness of filgrastim in increasing neutrophils, which are essential in fighting infections during chemotherapy.

5. Which information shown in the table below about a patient who has just arrived in the emergency department is most urgent for the nurse to communicate to the healthcare provider?

• A. Heart rate
• B. Platelet count
• C. Abdominal pain
• D. White blood cell count

Correct answer: B

Rationale: The correct answer is B: Platelet count. The platelet count is severely decreased, indicating a risk for spontaneous bleeding, which is a critical condition requiring immediate attention. While heart rate, abdominal pain, and white blood cell count are important, a severely decreased platelet count poses a more imminent threat to the patient's health and requires urgent communication to the healthcare provider. The nurse should prioritize addressing this potentially life-threatening issue to ensure prompt intervention and management.
