1. What is the major cause of death for children older than 1 year in the United States?

• A. Heart disease
• B. Childhood cancer
• C. Unintentional injuries
• D. Congenital anomalies

Correct answer: C

Rationale: Unintentional injuries are the leading cause of death among children older than 1 year in the United States.

2. A child is hospitalized in acute renal failure and has a serum potassium greater than 7 mEq/L. What temporary measures that will produce a rapid but transient effect to reduce the potassium should the nurse expect to be prescribed? (Select all that apply.)

• A. Dialysis
• B. All below
• C. Sodium bicarbonate
• D. Glucose 50% and insulin

Correct answer: A

Rationale: Calcium gluconate, sodium bicarbonate, and glucose with insulin are used as temporary measures to rapidly reduce serum potassium levels. They help shift potassium into cells and stabilize the heart but do not remove potassium from the body like dialysis does.

3. 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.

4. At which age should the nurse expect an infant to begin smiling in response to pleasurable stimuli?

• A. 1 month

• C. 3 months
• D. 4 months

Correct answer: B

Rationale: Infants typically begin to smile in response to pleasurable stimuli by 2 months, which is an early sign of social interaction and emotional development.

5. A child has a nasogastric (NG) tube after surgery for Hirschsprung disease. What is the purpose of the NG tube?

• C. Prevent abdominal distention.

Correct answer: C

Rationale: The primary purpose of an NG tube post-surgery for Hirschsprung disease is to prevent abdominal distention by decompressing the stomach and intestines. This helps prevent complications and promotes healing.
