Correct Answer: B

Rationale: The dorsogluteal muscle is contraindicated for immunizations in infants and young children due to the risk of injury to the sciatic nerve. The anterolateral thigh is the preferred site.

Correct Answer: C

Rationale: Diminished breath sounds in an infant are an abnormal finding and warrant further investigation to rule out conditions like atelectasis or pneumonia.

Correct Answer: C

Rationale: The correct answer is C, parallel play. Parallel play is observed when children play alongside each other but do not directly interact. In this scenario, each child is engaged in their own activity without engaging or influencing each other's play, which characterizes parallel play. Cooperative play (choice A) involves children playing together towards a common goal, which is not evident in the given situation. Solitary play (choice B) is when a child plays alone, unrelated to the presence of others. Associative play (choice D) involves more interaction and sharing of toys between children, which is not happening in the described play scenario.

Correct Answer: A

Rationale: The correct response is A. Solid foods, especially iron-fortified cereals, are introduced to meet the infant's increased nutritional needs, including iron, which breast milk alone may not provide adequately. Choice B is incorrect because the extrusion reflex is related to the tongue-thrust reflex, not the nutritional needs of the infant. Choice C is incorrect as breastfeeding does not become painful when the infant gets more teeth, and it is not a reason for introducing solid foods. Choice D is incorrect as the infant's interest in trying new skills is not a primary reason for introducing solid foods at this age.

Correct Answer: C

Rationale: Providing a simple explanation satisfies the child's curiosity and helps reduce any anxiety about the procedure.
