1. A major reason for the development of respiratory distress syndrome in the preterm infant is:

• A. Excessive surfactant
• B. Lack of surfactant
• C. Immature immune system
• D. Lack of body fat

Correct answer: B

Rationale: The correct answer is B: Lack of surfactant. Respiratory distress syndrome (RDS) in preterm infants is primarily due to a lack of surfactant, which is crucial for keeping the lungs inflated. Without adequate surfactant, the alveoli collapse, leading to breathing difficulties. Choice A, Excessive surfactant, is incorrect as RDS is caused by an insufficient amount of surfactant. Choice C, Immature immune system, and Choice D, Lack of body fat, are not directly related to the development of respiratory distress syndrome in preterm infants.

2. What is a key distinguishing feature of bronchiolitis in infants?

• A. Dry cough
• B. Wheezing
• C. Stridor
• D. Productive cough

Correct answer: B

Rationale: The correct answer is B: Wheezing. Wheezing is a key distinguishing feature of bronchiolitis in infants, typically caused by respiratory syncytial virus (RSV) infection. Bronchiolitis is characterized by inflammation and mucus buildup in the small airways of the lungs, leading to wheezing sounds during breathing. Choices A, C, and D are incorrect because dry cough, stridor, and productive cough are not typical features of bronchiolitis in infants.

3. What is the best age to introduce solid food into an infant’s diet?

• A. 2 to 3 months
• B. 4 to 6 months
• C. When birth weight has tripled
• D. When tooth eruption has started

Correct answer: B

Rationale: The introduction of solid foods is recommended at 4 to 6 months when the infant's digestive system is more developed and ready for solids.

4. The nurse is teaching parents about high-fiber foods that can prevent constipation. What foods should the nurse include in the teaching?

• A. Oranges
• B. All are correct
• C. Lima beans
• D. Baked beans

Correct answer: B

Rationale: The correct answer is B: All are correct. High-fiber foods like oranges, lima beans, baked beans, and raisin bran cereal are effective in preventing constipation. Oranges are a good source of fiber, lima beans and baked beans are high in fiber content, and raisin bran cereal is also rich in fiber. Bananas, which are not listed but could be considered by some as a high-fiber food, are actually low in fiber and may not be as effective in preventing constipation. Therefore, the nurse should include all the options provided in the teaching to help prevent constipation effectively.

5. In the newborn, into what muscle is intramuscular vitamin K administered?

• A. Deltoid
• B. Dorsogluteal
• C. Rectus femoris
• D. Vastus lateralis

Correct answer: D

Rationale: In newborns, intramuscular vitamin K is traditionally administered into the vastus lateralis muscle. This site is preferred due to its large muscle mass and accessibility. The dorsogluteal site is not recommended for newborns due to the risk of injury to the sciatic nerve. The deltoid site is also not recommended for newborns. The rectus femoris muscle is not commonly used for intramuscular injections in newborns.
