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 coarctation 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 findings are consistent with coarctation of the aorta, where narrowing of the aorta leads to decreased blood flow to the lower extremities. This results in higher blood pressure in the arms compared to the lower extremities, pounding brachial pulses, and slightly palpable femoral pulses. Choices A, C, and D are incorrect because they do not align with the pathophysiological mechanisms of coarctation of the aorta, which specifically involves narrowing of the aortic lumen reducing blood flow to the lower extremities.

2. After reinforcing information on treating a sprained ankle, what statement by the adolescent indicates to the practical nurse that further instruction is needed?

• A. Keep the leg elevated when sitting.
• B. Wrap the ankle in an elastic bandage for support.
• C. Apply warm compresses to the ankle for the first 24 hours.
• D. Put an ice pack on the ankle, alternating 30 minutes on and 30 minutes off.

Correct answer: C

Rationale: The correct answer is C. Applying warm compresses to a sprained ankle within the first 24 hours is incorrect as it can increase swelling and inflammation. Instead, cold compresses are recommended to help reduce swelling and pain. Option A, keeping the leg elevated, helps in reducing swelling. Option B, wrapping the ankle in an elastic bandage, provides support. Option D, using an ice pack in intervals, is effective in reducing swelling and pain. Therefore, the statement about applying warm compresses indicates the need for further instruction.

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

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

Correct answer: C

Rationale: The correct action for the nurse to implement when the chemotherapy infusion is complete is to flush the mediport with saline and heparin solution. This process helps prevent clotting and ensures the patency of the port, which is essential for future medication administrations and blood draws. Administering Zofran (Choice A) is not necessary after completing the chemotherapy infusion. Obtaining blood samples (Choice B) for RBCs, WBCs, and platelets is important but not the immediate action after completing the infusion. Initiating an infusion of normal saline (Choice D) is not required unless there is a specific indication for it.

4. A mother brings her 2-year-old son to the clinic because he has been crying and pulling on his earlobe for the past 12 hours. The child's oral temperature is 101.2°F. Which intervention should the nurse implement?

• A. Ask the mother if the child has had a runny nose
• B. Cleanse purulent exudate from the affected ear canal
• C. Apply a topical antibiotic to the periauricular area
• D. Provide parent education to prevent recurrence

Correct answer: A

Rationale: In a child presenting with ear pain and fever, asking if the child has had a runny nose is crucial in assessing possible causes of an ear infection. Respiratory infections can lead to secondary ear infections, so exploring symptoms related to upper respiratory tract infections, like a runny nose, can help in the evaluation and management of the child's condition. Choice B is incorrect because cleansing purulent exudate should be done by a healthcare provider, not a nurse, and only if necessary. Choice C is incorrect because applying a topical antibiotic without proper evaluation and prescription is not within the nurse's scope of practice. Choice D is incorrect because while parent education may be necessary, addressing the immediate concern of evaluating possible causes of the ear pain and fever takes priority.

5. A mother brings her 3-month-old infant to the clinic because the baby does not sleep through the night. Which finding is most significant in planning care for this family?

• A. The mother is a single parent and lives with her parents
• B. The mother states the baby is irritable during feedings
• C. The infant's formula has been changed twice
• D. The diaper area shows severe skin breakdown

Correct answer: D

Rationale: Severe skin breakdown in the diaper area is significant as it indicates a potential severe issue that needs immediate attention to prevent further complications. Skin breakdown can lead to infections and discomfort for the infant, making it a priority in planning care for this family. The other findings, such as the mother's living situation, baby's irritability during feedings, or formula changes, are important but do not pose immediate risks to the infant's health compared to severe skin breakdown.
