Nursing Elites

1. A patient with pancytopenia of unknown origin is scheduled for the following diagnostic tests. The nurse will provide a consent form to sign for which test?

• A. Bone marrow biopsy
• B. Abdominal ultrasound
• C. Complete blood count (CBC)
• D. Activated partial thromboplastin time (aPTT)

Correct answer: A

Rationale: In the case of a patient with pancytopenia of unknown origin, a bone marrow biopsy is usually indicated to determine the cause. A bone marrow biopsy is a minor surgical procedure that requires the patient or guardian to sign a surgical consent form. Abdominal ultrasound (Choice B) is not typically used to diagnose pancytopenia. A Complete Blood Count (CBC) (Choice C) is a routine blood test and does not require a specific consent form. Activated Partial Thromboplastin Time (aPTT) (Choice D) is a coagulation test and not typically performed to diagnose pancytopenia.

2. A patient who had a total hip replacement had an intraoperative hemorrhage 14 hours ago. Which laboratory test result would the nurse expect?

• A. Hematocrit of 46%
• B. Hemoglobin of 13.8 g/dL
• C. Elevated reticulocyte count
• D. Decreased white blood cell (WBC) count

Correct answer: C

Rationale: The correct answer is C: Elevated reticulocyte count. Hemorrhage leads to the release of reticulocytes (immature red blood cells) from the bone marrow into circulation as a compensatory mechanism to replenish lost red blood cells. This response helps in restoring the oxygen-carrying capacity of the blood. Choices A and B, hematocrit of 46% and hemoglobin of 13.8 g/dL, may not reflect the immediate response to hemorrhage within 14 hours. Choice D, decreased white blood cell (WBC) count, is not directly related to the body's response to hemorrhage.

3. The nurse is educating a patient who was discharged from the hospital after having cardiac surgery one week ago. The nurse recognizes the patient understands medication management when he/she states:

• A. I need to take my Lisinopril daily to reduce my risk of heart failure
• B. I only need to take the metoprolol when I feel my heart skip a beat
• C. I should carry my nitroglycerin pills in my pocket at all times
• D. I should only take the pain pills when my pain is really bad

Correct answer: A

Rationale: The correct answer is A. Lisinopril is commonly prescribed post-cardiac surgery to manage blood pressure and reduce the risk of heart failure. It is important for the patient to take Lisinopril daily as prescribed to achieve optimal outcomes. Choice B is incorrect as metoprolol is usually prescribed on a regular schedule to manage heart conditions, not just when symptoms occur. Choice C is incorrect because nitroglycerin should be kept in a cool, dry place, not in a pocket where it could be exposed to heat or moisture. Choice D is incorrect as pain medication should be taken as prescribed for adequate pain control, not just when pain is severe.

4. An appropriate nursing intervention for a hospitalized patient with severe hemolytic anemia is to

• A. provide a diet high in vitamin K
• B. alternate periods of rest and activity
• C. teach the patient how to avoid injury
• D. place the patient on protective isolation

Correct answer: B

Rationale: In severe hemolytic anemia, the priority nursing intervention is to alternate periods of rest and activity. This approach helps to balance activity levels to prevent excessive fatigue while promoting mobility and preventing complications such as muscle weakness or deconditioning. Providing a diet high in vitamin K (choice A) is not directly related to managing hemolytic anemia. Teaching the patient how to avoid injury (choice C) is important but may not be the immediate priority. Placing the patient on protective isolation (choice D) is not indicated for hemolytic anemia, as it is not a contagious condition.

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.
