Correct Answer: B

Rationale: The correct answer is B: Anterior. The anterior fontanel usually remains open until about 12-18 months of age, while the posterior fontanel closes by 2-3 months. Choices A, C, and D are incorrect as the posterior fontanel closes by 2-3 months of age, and the sphenoid and lambdoid fontanels are not typically assessed in routine infant head examinations.

Correct Answer: B

Rationale: Comforting and cuddling a 2-month-old baby when they cry helps build trust and security. At this age, responding to cries does not lead to spoiling, but rather supports healthy emotional development.

Correct Answer: B

Rationale: The correct answer is B: 60 minutes. School-aged children require at least 60 minutes of physical activity daily according to recommendations. This level of activity helps in promoting overall health, development, and well-being. Choice A (30 minutes) is incorrect as it falls short of the recommended duration. Choice C (90 minutes) is excessive and not the standard guideline for this age group. Choice D (15 minutes) is insufficient to meet the physical activity needs of school-aged children.

Correct Answer: D

Rationale: Coughing with excessive secretion is a common sign of tracheoesophageal fistula. In this condition, the connection between the trachea and esophagus allows saliva and food to enter the airways, leading to coughing and excessive secretions. Choice A, jaundice, is not typically associated with tracheoesophageal fistula. Hyperactive bowel sounds (Choice B) are more likely seen in conditions like gastroenteritis. Absence of sucking and vomiting (Choice C) is not a typical finding related to tracheoesophageal fistula.

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.
