Nursing Elites

1. 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.

2. A patient's complete blood count (CBC) shows a hemoglobin of 19 g/dL and a hematocrit of 54%. Which question should the nurse ask to determine possible causes of this finding?

• A. Have you had any recent weight loss?
• B. Do you have any history of lung disease?
• C. Have you noticed any dark or bloody stools?
• D. What is your dietary intake of meats and proteins?

Correct answer: B

Rationale: The correct answer is B: "Do you have any history of lung disease?" The elevated hemoglobin and hematocrit levels suggest polycythemia, which can be seen in conditions like chronic obstructive pulmonary disease (COPD). Option A is less relevant as weight loss is not typically associated with these blood count findings. Option C is more indicative of gastrointestinal bleeding rather than a respiratory issue. Option D focuses on dietary factors, which are less likely to cause such significant elevations in hemoglobin and hematocrit levels as seen in this case.

3. 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.

4. A 62-year-old man with chronic anemia is experiencing increased fatigue and occasional palpitations at rest. The nurse would expect the patient's laboratory test findings to include

• A. an RBC count of 4,500,000/μL.
• B. a hematocrit (Hct) value of 38%.
• C. normal red blood cell (RBC) indices.
• D. a hemoglobin (Hgb) of 8.6 g/dL.

Correct answer: B

Rationale: The correct answer is B. In chronic anemia, the hematocrit (Hct) value is a crucial indicator of the proportion of red blood cells in the blood. A hematocrit value of 38% indicates a lower than normal level of red blood cells, which aligns with the patient's symptoms of fatigue and palpitations. Choices A, C, and D are incorrect because a low RBC count, normal RBC indices, and a hemoglobin level of 8.6 g/dL do not specifically address the decreased red blood cell mass associated with chronic anemia.

5. The nurse is reviewing laboratory results and notes a patient's activated partial thromboplastin time (aPTT) level of 28 seconds. The nurse should notify the health care provider in anticipation of adjusting which medication?

• A. Aspirin
• B. Heparin
• C. Warfarin
• D. Erythropoietin

Correct answer: B

Rationale: The correct answer is B: Heparin. An activated partial thromboplastin time (aPTT) level of 28 seconds indicates a prolonged time, which is associated with heparin administration. Heparin is an anticoagulant medication that affects the intrinsic pathway of the coagulation cascade, leading to an increased aPTT. Aspirin (choice A) affects platelet aggregation and does not directly impact aPTT. Warfarin (choice C) affects the extrinsic pathway of the coagulation cascade and is monitored using the international normalized ratio (INR), not aPTT. Erythropoietin (choice D) is not related to coagulation parameters.
