Rationale: The correct answer is A: 'Industry vs. inferiority.' According to Erikson's theory, school-age children (approximately 6-12 years old) are in the stage of industry vs. inferiority. In this stage, children focus on developing a sense of competence and productivity. Choice B, 'Autonomy vs. shame and doubt,' is incorrect as it refers to the stage that occurs during early childhood (1-3 years old). Choice C, 'Identity vs. role diffusion,' pertains to adolescence (12-18 years old). Choice D, 'Trust vs. mistrust,' is related to the stage of infancy (0-1 year old). Therefore, option A is the most appropriate stage for school-age children in Erikson's theory.

Correct Answer: A

Rationale: The Advisory Committee on Immunization Practices (ACIP) of the Centers for Disease Control and Prevention (CDC) and American College of Obstetricians and Gynecologists recommend that pregnant adolescents and women without protection against pertussis should receive the Tdap vaccine ideally between 27 and 36 weeks of gestation or postpartum before discharge from the hospital. This timeframe allows for the development of antibodies in the mother to protect her and provide passive immunity to the infant. Administering the vaccine during the first trimester (Choice D) is not recommended as the optimal time is between 27 and 36 weeks. Choice B, during the first prenatal visit, is too early for optimal protection, and Choice C, 24 hours prior to delivery, does not provide enough time for the vaccine to be effective before birth.

Correct Answer: C

Rationale: The most appropriate approach when performing a physical assessment on a toddler is to use minimum physical contact initially. This helps gain the toddler's cooperation and reduces their distress. Performing traumatic procedures last is crucial as they are likely to upset the child and should be handled with care. Demonstrating the use of equipment may be complex for toddlers to understand, so it is not the most appropriate initial approach. Proceeding systematically in a head-to-toe direction is a good practice but using minimum physical contact initially is more important to establish trust and cooperation with the toddler.

Correct Answer: B

Rationale: Infants should be placed rear-facing in the back seat until they are at least 2 years old or exceed the weight/height limit of their car seat for optimal safety.
