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. What is a physical characteristic of infants whose mothers smoked during pregnancy?

• A. Being large for gestational age
• B. Growth restriction in weight only
• C. Preterm but size appropriate for gestational age
• D. Growth restriction in weight, length, and chest and head circumference

Correct answer: D

Rationale: The correct answer is D: Growth restriction in weight, length, and chest and head circumference. Infants born to mothers who smoke during pregnancy exhibit growth failure in weight, length, chest, and head circumference. This growth failure is directly related to the number of cigarettes smoked by the mother. Choices A, B, and C are incorrect because infants exposed to maternal smoking do not tend to be large for gestational age, experience growth restriction in weight only, or be preterm but size appropriate for gestational age.

3. What condition is often associated with severe diarrhea?

• A. Metabolic acidosis
• B. Metabolic alkalosis
• C. Respiratory acidosis
• D. Respiratory alkalosis

Correct answer: A

Rationale: Severe diarrhea can lead to a loss of bicarbonate, resulting in metabolic acidosis. This is a common complication of prolonged or severe diarrhea, especially in children.

4. What pathologic process is believed to be responsible for the development of postinfectious glomerulonephritis?

• A. Infarction of renal vessels
• B. Immune complex formation and glomerular deposition
• C. Bacterial endotoxin deposition on and destruction of glomeruli
• D. Embolization of glomeruli by bacteria and fibrin from endocardial vegetation

Correct answer: B

Rationale: Postinfectious glomerulonephritis is typically caused by immune complex deposition in the glomeruli following a streptococcal infection. This immune response leads to inflammation and impaired kidney function.

5. Congenital defects of the genitourinary tract, such as hypospadias, are usually repaired as early as possible to accomplish what?

• A. Minimize separation anxiety
• B. Prevent urinary complications.
• C. Increase acceptance of hospitalization.
• D. Promote development of normal body image.

Correct answer: D

Rationale: Early repair of congenital genitourinary defects like hypospadias is important to promote a normal body image and avoid psychological issues as the child grows. It also helps prevent urinary complications and allows for normal development.
