1. At what age is the first dose of the hepatitis A vaccine recommended to be started?

• A. 1 year
• B. 1 month
• C. 12 years
• D. It is not recommended at any age

Correct answer: A

Rationale: The correct answer is A: 1 year. The hepatitis A vaccine is now recommended for all children starting at age 1 year (i.e., 12 to 23 months). This is due to the recognition of hepatitis A as a significant child health problem, especially in areas with high infection rates. The virus is primarily spread through fecal-oral transmission, person-to-person contact, ingestion of contaminated food or water, and rarely through blood transfusion. Administering the first dose at 1 year helps protect children from this infection. Choices B and C are incorrect as the vaccine is not recommended at 1 month or 12 years. Choice D is also incorrect as the hepatitis A vaccine is recommended at a specific age to prevent the infection.

2. Why are neonates predisposed to problems with thermoregulation?

• A. Renal function is not fully developed
• B. Flexed posture favors heat loss
• C. A large body surface area favors heat loss to the environment
• D. A thick layer of subcutaneous fat provides excellent insulation

Correct answer: C

Rationale: Newborns have a large surface area relative to their body weight, making them more susceptible to heat loss and requiring careful thermoregulation. Choice A is incorrect because renal function is not directly related to thermoregulation. Choice B is incorrect because a flexed posture actually helps reduce heat loss by minimizing the surface area exposed to the environment. Choice D is incorrect because neonates have limited subcutaneous fat, which contributes to their susceptibility to heat loss.

3. An infant is brought to the emergency department with the following clinical manifestations: poor skin turgor, weight loss, lethargy, tachycardia, and tachypnea. This is suggestive of which situation?

• A. Water excess
• B. Sodium excess
• C. Water depletion
• D. Potassium excess

Correct answer: C

Rationale: These symptoms are indicative of dehydration or water depletion, which is common in infants and can rapidly lead to severe consequences if not addressed promptly.

4. A 14-month-old child is admitted to the hospital with laryngotracheobronchitis (LTB). Which assessment findings should the nurse expect?

• A. Cyanosis and dyspnea
• B. Productive cough and high fever
• C. Barking cough and inspiratory stridor
• D. Pale laryngeal and dyspnea

Correct answer: C

Rationale: The correct answer is C: 'Barking cough and inspiratory stridor.' Classic signs of laryngotracheobronchitis (LTB) include a barking cough, often described as a seal-like cough, and inspiratory stridor, which is a high-pitched sound heard during inspiration. These symptoms occur due to inflammation and narrowing of the upper airway. Choices A, B, and D are incorrect as they do not align with the typical assessment findings of LTB. Cyanosis and dyspnea (Choice A) may occur in severe cases but are not specific to LTB. Productive cough and high fever (Choice B) are more indicative of lower respiratory tract infections. Pale laryngeal and dyspnea (Choice D) are not characteristic findings of LTB.

5. What is the most common cause of acute gastroenteritis in children under 5 years?

• A. Salmonella
• B. Rotavirus
• C. Norovirus
• D. Shigella

Correct answer: B

Rationale: Rotavirus is the leading cause of acute gastroenteritis in children under 5 years. It leads to severe diarrhea and dehydration. Vaccination against rotavirus has significantly reduced the incidence of this disease, but it remains a major cause of morbidity in young children globally. Salmonella and Shigella can cause gastroenteritis, but they are less common in children under 5 years. Norovirus is also a common cause of gastroenteritis, but Rotavirus is the most prevalent in this age group.
