1. What physiologic state(s) produces the clinical manifestations of nervous system stimulation and excitement, such as overexcitability, nervousness, and tetany?

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

Correct answer: D

Rationale: Both metabolic and respiratory alkalosis can cause overexcitability and nervous system stimulation due to a decrease in ionized calcium levels, which can cause symptoms such as tetany and paresthesias. Acidosis typically has the opposite effect, leading to depression of the nervous system.

2. 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.

3. Which developmental milestone would the nurse expect an 11-month-old infant to have achieved?

• A. Sitting independently
• B. Turning a doorknob
• C. Building a tower of four cubes
• D. Walking independently

Correct answer: A

Rationale: The correct answer is A: Sitting independently. By 11 months, most infants can sit independently. This milestone usually precedes walking, which typically occurs closer to 12 months. Turning a doorknob and building a tower of four cubes involve more complex motor skills that are typically achieved later in development. Therefore, at 11 months, sitting independently is the milestone that the nurse would expect an infant to have achieved.

4. Which type of play would be most beneficial for preparing a preschool-age child for upcoming surgery to reduce the stress of the event?

• A. Cooperative play
• B. Associative play
• C. Dramatic play
• D. Onlooker play

Correct answer: C

Rationale: Dramatic play involves role-playing, allowing children to act out scenarios and become more comfortable with them. This type of play can help reduce anxiety about upcoming events like surgery. Cooperative play involves working together towards a common goal, associative play involves loosely interacting with others, and onlooker play involves observing others play without actively participating. These types of play are not as directly related to preparing a child for surgery and reducing stress as dramatic play.

5. Which is the most frequently used test for measuring visual acuity?

• A. Snellen letter chart
• B. Ishihara vision test
• C. Allen picture card test
• D. Denver eye screening test

Correct answer: A

Rationale: The Snellen letter chart is the most commonly used test for measuring visual acuity, particularly in school-age children and adults.
