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. The nurse reviews the laboratory test results of a patient admitted with abdominal pain. Which information will be most important for the nurse to communicate to the health care provider?

• A. Monocytes 4%
• B. Hemoglobin 13.6 g/dL
• C. Platelet count 168,000/μL
• D. White blood cell (WBC) count 15,500/μL

Correct answer: A

Rationale: The correct answer is A. A low percentage of monocytes can indicate a viral infection. This is crucial information to communicate as it suggests a specific type of infection that may require targeted treatment. Choices B, C, and D do not directly relate to an infectious process and are within normal ranges, so they are not as urgent to communicate to the healthcare provider in this context.

4. The health care provider orders a liver and spleen scan for a patient who has been in a motor vehicle crash. Which action should the nurse take before this procedure?

• A. Check for any iodine allergy.
• B. Insert a large-bore IV catheter.
• C. Administer prescribed sedatives.
• D. Assist the patient to a flat position.

Correct answer: D

Rationale: Before a liver and spleen scan, it is essential to assist the patient to a flat position. This position helps obtain clear images of the liver and spleen. Checking for iodine allergy (Choice A) is more relevant for procedures involving contrast dye, not a liver and spleen scan. Inserting a large-bore IV catheter (Choice B) may not be necessary for this specific procedure. Administering sedatives (Choice C) is not typically required for a liver and spleen scan, as the patient needs to remain still during the procedure.

5. A postoperative patient receiving a transfusion of packed red blood cells develops chills, fever, headache, and anxiety 35 minutes after the transfusion is started. After stopping the transfusion, what action should the nurse take?

• A. Give the PRN diphenhydramine
• B. Send a urine specimen to the laboratory
• C. Administer PRN acetaminophen (Tylenol)
• D. Draw blood for a new type and crossmatch

Correct answer: C

Rationale: The patient’s clinical manifestations are consistent with a febrile, nonhemolytic transfusion reaction. The transfusion should be stopped and antipyretics administered for the fever as ordered.
