Correct Answer: B

Rationale: The correct answer is B: Associative. Associative play is common in preschoolers, where children engage in separate activities but interact by sharing toys and talking with each other. This stage is characterized by more social interaction than solitary play (option A), where children play alone without interacting with others. Cooperative play (option C) involves children working together towards a common goal, which is typically seen in older children. Parallel play (option D) is when children play alongside each other but do not actively engage with one another, which is more common in toddlers.

Correct Answer: A

Rationale: The American Academy of Pediatrics advocates for exclusive breastfeeding until 1 year of age as the best form of infant nutrition. Breastfeeding for the first year of life provides optimal nutrition and benefits for the infant. Exclusive breastfeeding until 6 months of age is not in line with the AAP's recommendation for a full year. While commercially prepared infant formula is an alternative if breastfeeding is not possible, it is not the preferred choice according to AAP guidelines. The recommendation for commercial infant formula until 1 year of age is not in line with the AAP's stance on the benefits of extended breastfeeding.

Correct Answer: C

Rationale: The correct answer is C. Introducing iron-fortified cereal between 4 to 6 months of age is a recommended practice to prevent iron deficiency anemia in infants. Iron-fortified infant cereals are a good source of iron for infants. Choices A and B are incorrect because adding green leafy vegetables to low-iron formula and discontinuing vitamin C supplements do not directly address the prevention of iron deficiency anemia. Choice D is incorrect because cow's milk should be avoided before 12 months of age as it is low in iron and can lead to intestinal blood loss, increasing the risk of iron deficiency anemia.

Correct Answer: A

Rationale: Picking up a pencil requires the use of the pincer grasp, which involves the coordination of the thumb and forefinger to hold small objects. The pincer grasp is a fine motor skill essential for tasks that necessitate precision and dexterity. Choices B, C, and D are incorrect. Prehension refers to the act of grasping or holding an object, parachute reflex is a protective response to sudden movement or loss of support, and grasp reflex is an automatic closing of the hand when an object is placed in the palm, none of which specifically relate to the action of picking up a pencil.

Correct Answer: C

Rationale: Persistence in feeding, introducing new foods slowly, and maintaining a calm temperament are key strategies in managing FTT. A stimulating atmosphere may overwhelm the child and should be minimized during feeding times.
