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. The child is 3 years old and is 2 hours postop from a cardiac catheterization via the right femoral artery. Which assessment finding indicates arterial obstruction?

• A. Blood pressure is decreasing, and the pulse is rapid and irregular.
• B. The right foot feels cool to the touch and appears pale and blanched.
• C. The pulse distal to the femoral artery is weaker in the left foot than the right foot.
• D. The pressure dressing at the right femoral area is damp and oozing blood.

Correct answer: B

Rationale: A cool, pale, and blanched foot is indicative of arterial obstruction, leading to poor blood flow. This finding requires immediate intervention to prevent further complications such as tissue damage or necrosis. Monitoring for signs of arterial compromise, such as color changes, temperature, and capillary refill, is crucial in detecting and managing vascular complications post-cardiac catheterization. Choices A, C, and D do not directly indicate arterial obstruction. While a decreasing blood pressure and rapid, irregular pulse may suggest compromise, these findings are more nonspecific. A weaker pulse distal to the femoral artery indicates reduced perfusion but not necessarily arterial obstruction. Finally, a damp, oozing pressure dressing suggests a dressing issue rather than arterial obstruction.

3. The nurse is assessing a 4-month-old infant who has just received routine immunizations. The mother reports that the baby has been fussy and has a low-grade fever since the immunizations. What is the best response by the nurse?

• A. These are common side effects and should resolve within a few days
• B. Your baby may be having an allergic reaction to the immunizations
• C. You should bring your baby to the clinic immediately for evaluation
• D. You should give your baby aspirin to help with the fever

Correct answer: A

Rationale: The correct response by the nurse is to reassure the mother that fussiness and low-grade fever are common side effects of immunizations in infants and should resolve within a few days. It is essential to educate the mother about these expected reactions to alleviate her concerns. Choice B is incorrect because allergic reactions to immunizations usually present with more severe symptoms such as difficulty breathing or swelling. Choice C is not warranted unless there are concerning symptoms present. Choice D is inappropriate as aspirin is contraindicated in infants due to the risk of Reye's syndrome.

4. The healthcare provider is preparing to administer a vaccine to a 5-year-old child. The child is visibly anxious and asks if the shot will hurt. What is the healthcare provider’s best response?

• A. It might hurt a little, but it will be over quickly
• B. It won't hurt at all, don't worry
• C. You're a big kid now, and big kids don't cry
• D. If you don't think about it, it won't hurt

Correct answer: A

Rationale: When a child expresses fear or anxiety about receiving a vaccination, it is essential for the healthcare provider to provide honest and reassuring information. Choice A acknowledges the potential for some discomfort but also reassures the child that it will be over quickly. This response validates the child's feelings while also preparing them for the procedure. Choices B, C, and D either provide false reassurance, dismiss the child's feelings, or suggest avoidance, which are not appropriate responses in this situation.

5. The infant scheduled for reduction of intussusception passes a soft-formed brown stool the day before the procedure. What intervention should the nurse implement?

• A. Instruct the parents that the infant needs to be NPO.
• B. Notify the healthcare provider of the passage of brown stool.
• C. Obtain a stool specimen for laboratory analysis.
• D. Ask the parents about recent changes in the infant's diet.

Correct answer: B

Rationale: Notifying the healthcare provider is crucial when an infant scheduled for intussusception reduction passes a soft-formed brown stool as it may indicate spontaneous reduction of the intussusception. The healthcare provider needs to be informed to assess if the procedure is still necessary or if further evaluation is required. Instructing the parents that the infant needs to be NPO (nothing by mouth) is not the immediate action required in this situation. Obtaining a stool specimen for laboratory analysis is not necessary as the soft-formed brown stool is likely a result of the intussusception spontaneously reducing. Asking about recent changes in the infant's diet is not the most appropriate action when brown stool is passed before the procedure for intussusception reduction.
