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. What should the nurse do first for a 6-year-old with asthma showing a prolonged expiratory phase, wheezing, and 35% of personal best peak expiratory flow rate (PEFR)?

• A. Administer a prescribed bronchodilator.
• B. Encourage the child to cough and take deep breaths.
• C. Report the findings to the healthcare provider.
• D. Identify the triggers that precipitated this attack.

Correct answer: A

Rationale: Administering a bronchodilator is the priority action in managing an acute asthma exacerbation in a child. Bronchodilators help to relax the muscles around the airways, opening them up and improving breathing. This intervention aims to address the immediate breathing difficulty and should be done promptly to provide relief for the child. Encouraging coughing and deep breaths (choice B) may worsen the child's condition by further constricting the airways. Reporting findings to the healthcare provider (choice C) is important but not the immediate priority in this acute situation. Identifying triggers (choice D) is crucial for long-term asthma management but is not the first step when managing an acute exacerbation.

3. A parent of a 2-month-old infant, who was treated for pyloric stenosis, is receiving discharge instructions from a healthcare provider. Which statement by the parent indicates a need for further teaching?

• A. We will burp our baby more frequently during feedings
• B. We should feed our baby in an upright position
• C. We will lay our baby on their stomach after feeding
• D. We will start feeding our baby with small, frequent feedings

Correct answer: C

Rationale: Placing infants on their stomach after feeding increases the risk of sudden infant death syndrome (SIDS). It is important to educate parents to always place infants on their back to sleep to reduce this risk.

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. A 10-year-old child is admitted with diabetic ketoacidosis (DKA). Which laboratory value should the practical nurse (PN) anticipate?

• A. Elevated blood glucose.
• B. Decreased serum ketones.
• C. Low urine glucose.
• D. High bicarbonate levels.

Correct answer: A

Rationale: In a case of diabetic ketoacidosis (DKA), the primary feature is elevated blood glucose levels due to insulin deficiency. Additionally, ketones are increased in the blood and urine. Bicarbonate levels are usually low because of the metabolic acidosis that accompanies DKA. Therefore, the practical nurse should anticipate elevated blood glucose levels as a characteristic laboratory finding in a child admitted with DKA. Choice B is incorrect because serum ketones are increased in DKA. Choice C is incorrect because in DKA, urine glucose is typically high due to spillage of glucose into the urine. Choice D is incorrect because bicarbonate levels are usually low in DKA, not high.
