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. When should the surgical correction of hypospadias in a newborn infant typically be done?

• A. Repair should be done by one month to prevent bladder infection.
• B. To form a proper urethra repair, it should be done after sexual maturity.
• C. Repairs typically should be done before the child is potty trained.
• D. Delaying the repair until school age reduces castration fears.

Correct answer: C

Rationale: Surgical repairs for hypospadias are typically recommended to be performed before the child is potty trained. This timing helps in avoiding complications, ensures better outcomes, and makes the surgical process smoother. Early correction also minimizes the psychological impact on the child regarding genital differences and can improve long-term psychological well-being. Choices A, B, and D are incorrect because repairing hypospadias at one month to prevent bladder infection, after sexual maturity to form a proper urethra, or delaying the repair until school age to reduce castration fears are not the standard recommendations. The optimal timing for surgical correction is before the child is potty trained to achieve the best results and psychological outcomes.

3. The caregiver is teaching a group of parents about injury prevention for toddlers. Which statement by a parent indicates a need for further teaching?

• A. I will keep all cleaning supplies locked away.
• B. I will teach my child how to swim this summer.
• C. I will make sure my child wears a helmet while riding a tricycle.
• D. I will place my child in a car seat for every car ride.

Correct answer: B

Rationale: Teaching children how to swim is valuable, but parental supervision around water is essential to prevent drowning. It's crucial to emphasize constant supervision when young children are near water, regardless of their swimming abilities. The other choices (A, C, and D) demonstrate appropriate safety measures for injury prevention in toddlers, such as securing cleaning supplies, ensuring helmet use during tricycle rides, and using a car seat for every car ride.

4. A 2-week-old female infant is hospitalized for the surgical repair of an umbilical hernia. After returning to the postoperative neonatal unit, her RR and HR have increased during the last hour. Which intervention should the nurse implement?

• A. Notify the healthcare provider of these findings
• B. Administer a PRN analgesic as prescribed
• C. Document the findings in the infant's medical record
• D. Comfort the infant by swaddling and gently rocking

Correct answer: A

Rationale: In a postoperative neonatal setting, an increase in respiratory rate (RR) and heart rate (HR) in an infant could indicate pain or distress. It is crucial for the nurse to notify the healthcare provider promptly to assess the infant's condition and provide appropriate interventions. Prompt communication with the healthcare provider ensures timely evaluation and management of the infant's discomfort or distress, promoting optimal postoperative recovery and comfort. Administering analgesics without healthcare provider assessment could mask underlying issues, documenting findings alone does not address the immediate need for intervention, and comforting may not resolve the underlying cause of increased RR and HR.

5. A 15-month-old child is brought to the clinic for a routine checkup. The nurse notes that the child is not walking independently yet. What should the nurse do next?

• A. Refer the child for a developmental assessment
• B. Encourage the parents to start physical therapy
• C. Reassure the parents that some children walk later than others
• D. Discuss the importance of early intervention services

Correct answer: C

Rationale: The correct answer is to reassure the parents that some children walk later than others. It is essential to understand that children reach developmental milestones at different ages. Walking independently can occur later in some children, and it is normal. Referring the child for a developmental assessment (Choice A) may cause unnecessary concern at this stage. Encouraging physical therapy (Choice B) or discussing early intervention services (Choice D) may not be warranted unless there are specific concerns identified during the checkup.
