Correct Answer: D

Rationale: Discharge planning should begin on admission to ensure that all necessary teaching and preparations are completed in a timely manner. Starting discharge planning early allows for a comprehensive assessment of the patient's needs, coordination with the healthcare team, and adequate time for patient and family education. Choice A, post-operatively, is too late in the process and may lead to rushed planning. Choice B, right at discharge, may not allow enough time for thorough preparation. Choice C, on the morning of discharge, also does not provide sufficient time for effective planning and education.

Correct Answer: C

Rationale: By around 10 months, infants often start to say "mama" and "dada" with meaning, associating these words with their parents.

Correct Answer: A

Rationale: The correct setting for the infusion pump should be 60 mL/hour to deliver 30 mL in 30 minutes. To calculate the infusion rate in mL/hour, divide the total volume to be infused (30 mL) by the total time for infusion (30 minutes) and then multiply by 60 to convert minutes to hours. Therefore, 30 mL / 30 minutes * 60 minutes/hour = 60 mL/hour. Choices B, C, and D are incorrect because they do not match the calculation based on the given parameters.

Correct Answer: C

Rationale: Play is an effective way to communicate and build rapport with young children, especially pre-schoolers. It helps them feel comfortable, express themselves, and establish a connection with the caregiver. Lengthy discussions may not be suitable for their age and attention span, while explanation with drawings and models can enhance communication but may not engage them as effectively as play. Silence, on the other hand, may create a sense of unease or lack of interaction for pre-schoolers.

Correct Answer: A

Rationale: A pacifier with an easily grasped handle is safer and more convenient for the infant to use without the risk of choking hazards that detachable parts might pose.
