Nursing Elites

1. Which heart sound is produced by vibrations within the heart chambers or in the major arteries from the back-and-forth flow of blood?

• A. S1 and S2
• B. S3 and S4
• C. Murmur
• D. Physiologic splitting

Correct answer: C

Rationale: A murmur is produced by turbulent blood flow within the heart or major arteries, resulting in audible vibrations.

2. What is the most common cause of bronchiolitis in infants?

• A. Adenovirus
• B. Influenza virus
• C. Respiratory syncytial virus
• D. Parainfluenza virus

Correct answer: C

Rationale: The correct answer is C, Respiratory syncytial virus (RSV). RSV is the leading cause of bronchiolitis, a common respiratory condition in infants that results in inflammation of the small airways in the lung. It is highly contagious and can cause severe respiratory distress in young children, particularly those under 2 years old. Choice A, Adenovirus, is not the most common cause of bronchiolitis in infants. Choice B, Influenza virus, may cause respiratory infections but is not the primary cause of bronchiolitis. Choice D, Parainfluenza virus, can cause croup and other upper respiratory infections but is not the main cause of bronchiolitis in infants.

3. The nurse is teaching a parent with a 2-month-old infant who has been diagnosed with colic about ways to relieve colic. Which statement by the parent indicates the need for additional teaching?

• A. I should let my infant cry for at least 30 minutes before I respond.
• B. I will swaddle my infant tightly with a soft blanket.
• C. I should massage my infant's abdomen whenever possible.
• D. I will place my infant in an upright seat after feeding.

Correct answer: A

Rationale: Letting an infant cry for prolonged periods can exacerbate colic and increase the infant's distress. It is better to respond promptly to soothe the baby. Other methods like swaddling, gentle massage, and keeping the infant upright can help relieve colic symptoms.

4. An anxious 12-year-old child receives an injection from the nurse and sighs with relief when it is done. After a moment of reflection, the girl asks the nurse, 'Is it hard to give someone an injection?' This child’s question is evidence that the child has developed which cognitive skill?

• A. Conservation
• B. Accommodation
• C. Decentering
• D. Class inclusion

Correct answer: C

Rationale: The correct answer is C: Decentering. Decentering is the ability to consider multiple aspects of a situation, which the child's question demonstrates. In this scenario, the child's question shows that she is thinking beyond her own experience and considering the difficulty or complexity of giving an injection from the nurse's perspective. Choices A, B, and D are incorrect. Conservation refers to understanding that certain properties of an object remain the same despite changes in its appearance. Accommodation is the process of adjusting existing knowledge or creating new mental categories to incorporate new information. Class inclusion involves understanding the relationship between a whole set and its subsets, which is not demonstrated in the child's question.

5. The nurse determines that a child's intravenous infusion has infiltrated. The infused solution is a vesicant. What is the most appropriate nursing action?

• A. Stop the infusion and apply ice.
• B. End the infusion and notify the practitioner.
• C. Slow the infusion rate and notify the practitioner.
• D. Discontinue the infusion and apply warm compresses.

Correct answer: B

Rationale: If a vesicant solution infiltrates, stopping the infusion immediately and notifying the practitioner is critical to prevent tissue damage. Cold or warm compresses should only be applied following specific medical advice based on the vesicant involved.
