Correct Answer: D

Rationale: Encouraging the baby to fall asleep in the crib while still awake can help establish healthy sleep habits and reduce night waking.

Correct Answer: D

Rationale: The correct answer is D, 'Parallel.' Parallel play is a common play pattern observed in toddlers where they play alongside each other without direct interaction. This type of play allows toddlers to observe and mimic each other's actions, aiding in their social development. Choices A, B, and C are incorrect. Associative play involves some interaction between children, team play involves organized group activities, and solitary play is when a child plays alone, all of which are not typically exhibited by toddlers during play.

Correct Answer: A

Rationale: To calculate the dosage, multiply the child's weight (10 kg) by the dosage (8 mg/kg) which equals 80 mg. Since the concentration is 100 mg/5 mL, to find out how much to administer, you need to determine how many 5 mL doses are in 80 mg. It will be 80 mg · 100 mg * 5 mL = 4 mL. Therefore, the correct answer is 4 mL. Choice B, 2 mL, is incorrect because it does not account for the correct dosage calculation. Choice C, 5 mL, is incorrect as it does not consider the dosage based on the child's weight. Choice D, 3 mL, is incorrect as it does not reflect the accurate dosage calculation.

Correct Answer: B

Rationale: The primary nursing concern in this situation is the risk for aspiration. Popcorn is a choking hazard for infants, as their airway is not fully developed to handle solid foods like popcorn. Choices A, C, and D are incorrect because the main focus should be on the immediate risk of aspiration due to the inappropriate solid food given to the infant, rather than on nutritional imbalances or readiness for enhanced nutrition.

Correct Answer: B

Rationale: Infants typically begin to smile in response to pleasurable stimuli by 2 months, which is an early sign of social interaction and emotional development.
