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. 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.

3. 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.

4. Which patient statement to the nurse indicates a need for additional instruction about taking oral ferrous sulfate?

• A. I will call my health care provider if my stools turn black.
• B. I will take a stool softener if I feel constipated occasionally.
• C. I should take the iron with orange juice about an hour before eating.
• D. I should increase my fluid and fiber intake while I am taking iron tablets.

Correct answer: A

Rationale: It is normal for the stools to appear black when a patient is taking iron, and the patient should not call the health care provider about this.

5. 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.
