Nursing Elites

1. What is the first sign of puberty in boys?

• A. Enlargement of testes
• B. Decreased levels of testosterone
• C. Voice deepening
• D. Pubic hair

Correct answer: A

Rationale: The first sign of puberty in boys is typically the enlargement of the testes. This is due to the increase in production of testosterone, which leads to physical changes such as growth of the testes. Choice B, decreased levels of testosterone, is incorrect as puberty is marked by an increase in testosterone levels. Choice C, voice deepening, and choice D, pubic hair growth, usually occur later in the puberty process compared to testicular enlargement, making them incorrect answers.

2. When should a child receive the first dose of the hepatitis B virus (HBV) vaccine if the mother is hepatitis B surface antigen (HBsAg) negative?

• A. 2 months of age, before hospital discharge.
• B. Birth before discharge from the hospital.
• C. 6 months of age, at the third well-child visit.
• D. No time (this vaccine is not currently recommended).

Correct answer: B

Rationale: If the mother is HBsAg negative, it is recommended that the child receives the first dose of the hepatitis B vaccine at birth before discharge from the hospital. This is to provide early protection against the hepatitis B virus. The second dose of the vaccine is typically given at the first well-child visit, and the third dose is usually administered at a later date. The Advisory Committee on Immunization Practices of the Centers for Disease Control and Prevention and the Committee on Infectious Diseases of the American Academy of Pediatrics govern the recommendations for immunization, including the hepatitis B virus vaccine. Choice A is incorrect as the first dose should ideally be given at birth. Choice C is incorrect as waiting until 6 months of age may leave the child vulnerable to infection during the early months of life. Choice D is incorrect as the hepatitis B vaccine is recommended for all newborns, especially if the mother is HBsAg negative, to prevent transmission of the virus.

3. Which condition is characterized by a "barking" cough in children?

• A. Asthma
• B. Bronchiolitis
• C. Croup
• D. Pneumonia

Correct answer: C

Rationale: Croup is the correct answer. It is characterized by a distinctive "barking" cough, typically worse at night, caused by the inflammation of the upper airway, specifically the larynx and trachea. Asthma (Choice A) typically presents with wheezing and shortness of breath rather than a barking cough. Bronchiolitis (Choice B) commonly causes wheezing and respiratory distress in infants and young children. Pneumonia (Choice D) often presents with symptoms like fever, productive cough, and chest pain, but not typically a barking cough.

4. What is an appropriate nursing intervention for a child with minimal change nephrotic syndrome (MCNS) who has scrotal edema?

• A. Place an ice pack on the scrotal area.
• B. Place the child in an upright sitting position.
• C. Elevate the scrotum with a rolled washcloth.
• D. Place a warm moist pack to the scrotal area.

Correct answer: C

Rationale: Elevating the scrotum with a rolled washcloth helps reduce edema by promoting fluid drainage. Ice packs are not recommended due to the risk of frostbite, and warm moist packs are not typically used for this purpose. An upright position does not specifically address the edema.

5. The nurse is providing education to the parent of a child with Beta-thalassemia. Which risk factors about the condition should the nurse include in the teaching?

• A. Hypertrophy of the thyroid
• B. Polycythemia vera
• C. Thrombocytopenia
• D. Chronic hypoxia and iron overload

Correct answer: D

Rationale: The correct answer is D: Chronic hypoxia and iron overload. Children with Beta-thalassemia often suffer from chronic hypoxia due to ineffective erythropoiesis and require frequent blood transfusions, leading to iron overload. These complications must be managed to prevent organ damage. Choices A, B, and C are incorrect. Hypertrophy of the thyroid, polycythemia vera, and thrombocytopenia are not direct risk factors associated with Beta-thalassemia. Therefore, they should not be included in the teaching regarding this condition.
