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. Which collaborative problem will the nurse include in a care plan for a patient admitted to the hospital with idiopathic aplastic anemia?

• A. Potential complication: seizures
• B. Potential complication: infection
• C. Potential complication: neurogenic shock
• D. Potential complication: pulmonary edema

Correct answer: B

Rationale: The correct answer is B: Potential complication: infection. Patients with idiopathic aplastic anemia have pancytopenia, which puts them at a high risk for infections due to decreased production of all blood cells (red blood cells, white blood cells, and platelets). Infection is a significant concern in these patients. Choices A, C, and D are incorrect because seizures, neurogenic shock, and pulmonary edema are not typically associated with idiopathic aplastic anemia. While seizures can occur in some conditions that affect the brain, neurogenic shock is related to spinal cord injury, and pulmonary edema is more commonly seen in conditions like heart failure.

3. 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.

4. When providing care for a patient with sickle cell crisis, what is important for the nurse to do?

• A. Monitor the patient's intake of oral and IV fluids
• B. Evaluate the effectiveness of opioid analgesics
• C. Encourage the patient to ambulate as much as tolerated
• D. Educate the patient about high-protein, high-calorie foods

Correct answer: B

Rationale: The correct answer is to evaluate the effectiveness of opioid analgesics. In sickle cell crisis, pain is the most common symptom and is usually managed with large doses of continuous opioids. Monitoring fluid intake (Choice A) is important, but limiting fluids may not be necessary. Encouraging ambulation (Choice C) is generally good but may not be the priority during a sickle cell crisis. Educating the patient about nutrition (Choice D) is important for overall health but may not be the immediate focus during a crisis.

5. After a patient with pancytopenia undergoes a bone marrow aspiration from the left posterior iliac crest, which action would be important for the nurse to take?

• A. Elevate the head of the bed to 45 degrees.
• B. Have the patient lie on the left side for 1 hour.
• C. Apply a sterile 2-inch gauze dressing to the site.
• D. Use a half-inch sterile gauze to pack the wound.

Correct answer: B

Rationale: After a bone marrow aspiration, it is important to have the patient lie on the left side for 30 to 60 minutes to decrease the risk of bleeding. Elevating the head of the bed to 45 degrees does not directly address the risk of bleeding. Applying a sterile 2-inch gauze dressing to the site is important for wound care but does not specifically address post-procedural positioning. Using a half-inch sterile gauze to pack the wound is not necessary after a bone marrow aspiration.
