1. 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.
2. When should the nurse instruct parents to administer a daily proton pump inhibitor to their child with gastroesophageal reflux?
- A. At bedtime
- B. With a meal
- C. Midmorning
- D. 30 minutes before breakfast
Correct answer: D
Rationale: Proton pump inhibitors (PPIs) like omeprazole or lansoprazole are most effective when given 30 minutes before breakfast. This timing allows the medication to inhibit the proton pumps in the stomach that produce acid, providing better symptom control throughout the day. Administering the PPI at bedtime (choice A) may not be as effective as giving it before breakfast due to the timing of peak acid production during the day. Giving it with a meal (choice B) might affect the absorption and effectiveness of the medication. Midmorning administration (choice C) is not the recommended time for optimal PPI efficacy.
3. A thorough systemic physical assessment is necessary in the extremely low-birth-weight (ELBW) infant to detect what?
- A. Weight gain reflective of fluid retention
- B. Difficulties in maternal-child attachment
- C. Subtle changes that may be indicative of an underlying problem
- D. Changes in Apgar score over the first 24 hours of life
Correct answer: C
Rationale: In extremely low-birth-weight (ELBW) infants, a thorough systemic physical assessment is crucial to detect subtle changes that may indicate an underlying problem. These infants are highly vulnerable and may show signs of stress through changes in feeding behavior, activity, color, oxygen saturation, or vital signs. Monitoring weight in ELBW infants primarily reflects genitourinary function rather than fluid retention. Difficulties in maternal-child attachment are important but are usually assessed during parental visits and are not the primary focus of a systemic physical assessment. Changes in the Apgar score are used immediately after birth to assess the transition to extrauterine life and are not as relevant in the following 24 hours to detect ongoing subtle issues.
4. Using knowledge of child development, what approach is best when preparing a toddler for a procedure?
- A. Avoid asking the child to make choices.
- B. Plan for a teaching session to last about 20 minutes.
- C. Demonstrate on a doll how the procedure will be done.
- D. Show the necessary equipment without allowing child to handle it.
Correct answer: C
Rationale: Demonstrating on a doll helps the toddler understand what will happen in a non-threatening way, making the procedure less intimidating. Long teaching sessions or avoiding choices can increase anxiety.
5. What major complication is associated with a child with chronic renal failure?
- A. Hypokalemia
- B. Metabolic alkalosis
- C. Water and sodium retention
- D. Excessive excretion of blood urea nitrogen
Correct answer: C
Rationale: Water and sodium retention is a major complication in chronic renal failure, leading to hypertension and edema. Hypokalemia and metabolic alkalosis are less common, and while BUN levels rise, retention rather than excretion is problematic in chronic renal failure.
