Nursing Elites

1. 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.

2. The nurse is caring for a patient post coronary artery bypass graft who rates his/her pain as an 8 out of 10 on the subjective pain scale. Should the nurse choose to administer morphine sulfate intravenously as it has benefits to cardiac patients (select one that does not apply)?

• A. Decreasing myocardial oxygen supply
• B. Decreasing myocardial oxygen consumption
• C. Decreasing heart rate
• D. Increasing blood pressure

Correct answer: D

Rationale: Morphine sulfate, a potent opioid analgesic, can cause vasodilation leading to a decrease in blood pressure rather than an increase. Choice A is incorrect as morphine can decrease myocardial oxygen consumption by reducing the workload of the heart. Choice B is incorrect as morphine can decrease heart rate as a side effect. Choice C is incorrect as morphine typically decreases blood pressure rather than increasing it.

3. A 52-year-old patient has a new diagnosis of pernicious anemia. The nurse determines that the patient understands the teaching about the disorder when the patient states:

• A. I need to start eating more red meat and liver.
• B. I will stop having a glass of wine with dinner.
• C. I could choose nasal spray rather than injections of vitamin B12.
• D. I will need to take a proton pump inhibitor such as omeprazole (Prilosec).

Correct answer: C

Rationale: The correct answer is C. Pernicious anemia is a condition where the body can't absorb enough vitamin B12. Treatment usually involves lifelong replacement of vitamin B12. In this case, the patient understanding the disorder is correctly demonstrated by choosing nasal spray or injections of vitamin B12 for replacement therapy. Choices A, B, and D are incorrect because increasing red meat/liver intake, stopping wine consumption, or taking a proton pump inhibitor like omeprazole do not address the primary issue of vitamin B12 absorption in pernicious anemia.

4. Which statement by a patient indicates good understanding of the nurse’s teaching about prevention of sickle cell crisis?

• A. Home oxygen therapy is frequently used to decrease sickling.
• B. There are no effective medications that can help prevent sickling.
• C. Routine continuous dosage narcotics are prescribed to prevent a crisis.
• D. Risk for a crisis is decreased by having an annual influenza vaccination.

Correct answer: D

Rationale: Because infection is the most common cause of a sickle cell crisis, influenza, Haemophilus influenzae, pneumococcal pneumonia, and hepatitis immunizations should be administered.

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.
