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. During a follow-up clinical visit, a mother tells the nurse that her 5-month-old son, who had surgical correction for tetralogy of Fallot, has rapid breathing, often takes a long time to eat, and requires frequent rest periods. The infant is not crying while being held, and his growth is in the expected range. Which intervention should the nurse implement?

• A. Stimulate the infant to cry to produce cyanosis
• B. Auscultate the heart and lungs while holding the infant
• C. Evaluate the infant for failure to thrive
• D. Obtain a 12-lead electrocardiogram

Correct answer: B

Rationale: Auscultating the heart and lungs while the infant is held is the most appropriate intervention to assess his current condition. This action allows the nurse to gather important information regarding the cardiovascular and respiratory status of the infant, which is crucial in evaluating his post-surgical recovery and overall well-being. Option A is incorrect as stimulating the infant to cry intentionally is not necessary and could cause distress. Option C is incorrect as the infant's growth is within the expected range, indicating no signs of failure to thrive. Option D is incorrect as obtaining a 12-lead electrocardiogram is not the initial intervention needed in this situation; assessing the heart and lungs through auscultation is more immediate and informative.

3. A male infant with bronchiolitis is brought to the clinic by his mother. The infant is congested and febrile with a capillary refill of 2 seconds. Which information should the nurse discuss with the mother?

• A. Encourage the infant to play
• B. Limit the amount of oral intake
• C. Keep the infant isolated from others
• D. Place the infant on their back for naps

Correct answer: C

Rationale: Bronchiolitis is a highly contagious respiratory infection commonly caused by viruses. Isolating the infant from others is crucial to prevent the spread of the infection to other vulnerable individuals, especially those with weakened immune systems. Encouraging play may not be appropriate as the infant is sick and needs rest. Limiting oral intake might be necessary if the infant is having difficulty swallowing due to respiratory distress. Placing the infant on their back for naps is a safe sleep practice but not the priority in this situation where preventing transmission of the infection is crucial.

4. During a follow-up clinical visit, a mother tells the nurse that her 5-month-old son, who had surgical correction for tetralogy of Fallot, has rapid breathing, often takes a long time to eat, and requires frequent rest periods. The infant is not crying while being held, and his growth is in the expected range. Which intervention should the nurse implement?

• A. Stimulate the infant to cry to produce cyanosis
• B. Auscultate the heart and lungs while the infant is held
• C. Evaluate the infant for failure to thrive
• D. Obtain a 12-lead electrocardiogram

Correct answer: B

Rationale: Auscultating the heart and lungs while the infant is held can provide important diagnostic information in assessing the cardiac and respiratory status of the infant who had surgical correction for tetralogy of Fallot. This intervention can help the nurse identify any abnormal heart or lung sounds, which may indicate complications or issues that need further evaluation or intervention.

5. 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.
