Nursing Elites

1. The nurse is conducting an admission assessment of an 11-month-old infant with CHF who is scheduled for repair of restenosis of coarction of the aorta that was repaired 4 days after birth. Findings include blood pressure higher in the arms than the lower extremities, pounding brachial pulses, and slightly palpable femoral pulses. What pathophysiologic mechanisms support these findings?

• A. The aortic semilunar valve obstructs blood flow into the systemic circulation
• B. The lumen of the aorta reduces the volume of the blood flow to the lower extremities
• C. The pulmonic valve prevents adequate blood volume into the pulmonary circulation
• D. An opening in the atrial septum causes a murmur due to a turbulent left-to-right shunt

Correct answer: B

Rationale: The correct answer is B. Coarctation of the aorta causes narrowing of the aorta, reducing blood flow to the lower extremities. This narrowing results in higher blood pressure in the arms compared to the lower extremities, along with stronger brachial pulses and slightly palpable femoral pulses. Choices A, C, and D are incorrect because they do not align with the pathophysiological mechanism of coarctation of the aorta, which specifically leads to reduced blood flow to the lower extremities.

2. When reviewing the dietary guidelines for a child with nephrotic syndrome, which diet should the practical nurse reinforce with the parents?

• A. High protein.
• B. Low sodium.
• C. Low fat.
• D. High carbohydrate.

Correct answer: B

Rationale: The correct diet that the practical nurse should reinforce with the parents of a child with nephrotic syndrome is a low-sodium diet. This diet is crucial for managing fluid retention and reducing the risk of edema, which are common concerns in children with nephrotic syndrome.

3. A child with acute lymphocytic leukemia (ALL) who is receiving chemotherapy via a subclavian IV infusion has an oral temperature of 103 degrees. In assessing the IV site, the nurse determines that there are no signs of infection at the site. Which intervention is the most important for the nurse to implement?

• A. Obtain a specimen for blood cultures.
• B. Assess the CBC.
• C. Monitor the oral temperature every hour.
• D. Administer acetaminophen as prescribed.

Correct answer: A

Rationale: Obtaining a specimen for blood cultures is crucial in this situation as it helps identify the source of infection, if present, and guide appropriate treatment. This is important in a child with leukemia receiving chemotherapy to prevent potential complications and ensure timely intervention. Assessing the CBC may provide overall information on the child's condition but may not specifically identify a potential infection. Monitoring the oral temperature is important but obtaining blood cultures takes precedence in this scenario. Administering acetaminophen can help reduce fever but does not address the need to identify a possible infection source.

4. What action should the nurse implement after the infusion is complete for a 16-year-old with acute myelocytic leukemia receiving chemotherapy via an implanted medication port at the outpatient oncology clinic?

• A. Administer Zofran
• B. Obtain blood samples for RBCs, WBCs, and platelets
• C. Flush the mediport with saline and heparin solution
• D. Initiate an infusion of normal saline

Correct answer: C

Rationale: After completing the chemotherapy infusion via the implanted medication port, the nurse should flush the mediport with saline and heparin solution. This action helps prevent clot formation in the port, ensuring its patency for future use and reducing the risk of complications associated with catheter occlusion. Administering Zofran (Choice A) is used for managing chemotherapy-induced nausea and vomiting, not for post-infusion care. Obtaining blood samples for RBCs, WBCs, and platelets (Choice B) is important for monitoring the patient's blood count but is not the immediate post-infusion priority. Initiating an infusion of normal saline (Choice D) is not necessary after completing the chemotherapy infusion.

5. A 3-year-old child is admitted to the hospital with a diagnosis of pneumonia. The nurse notes that the child has a fever and is breathing rapidly. What is the nurse’s priority action?

• A. Administer antipyretic medication
• B. Obtain a chest X-ray
• C. Start the child on oxygen therapy
• D. Notify the healthcare provider

Correct answer: C

Rationale: In a child with pneumonia who is breathing rapidly, the priority action for the nurse is to start the child on oxygen therapy. This intervention is essential to ensure adequate oxygenation, which is crucial in managing respiratory distress and preventing complications associated with hypoxia. Administering antipyretic medication (Choice A) may help reduce the fever but does not address the immediate need for oxygen therapy. Obtaining a chest X-ray (Choice B) is important for diagnosis but providing oxygen is more urgent. Notifying the healthcare provider (Choice D) can be done after initiating oxygen therapy to update on the patient's condition.
