Correct Answer: A

Rationale: Letting an infant cry for prolonged periods can exacerbate colic and increase the infant's distress. It is better to respond promptly to soothe the baby. Other methods like swaddling, gentle massage, and keeping the infant upright can help relieve colic symptoms.

Correct Answer: C

Rationale: A frozen teething ring is effective for relieving teething pain as the cold helps numb the gums and reduce inflammation, making it a safe and effective method for managing discomfort

Correct Answer: A

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: D

Rationale: Colic is characterized by episodes of loud, inconsolable crying, often due to abdominal discomfort, and typically occurs in infants younger than 6 months. It is not related to poor mothering, nor does it necessarily result in weight loss.

Correct Answer: C

Rationale: For school-aged children, pedestrian, motor vehicle, and bike safety are critical areas to focus on as accidents involving these are common in this age group. Education about fire safety and toxic substances is also important, but the priority is on preventing accidents in everyday activities. Therefore, choices A, B, and D are not the most relevant for addressing the goal of decreasing injuries and accidents in this age group.
