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: LMX is an effective analgesic agent when applied to the skin 30 minutes before a procedure. It eliminates or reduces the pain from most procedures involving skin puncture. TAC provides skin anesthesia about 15 minutes after application to nonintact skin, making it more suitable for wound suturing. Transdermal fentanyl patches are designed for continuous pain control, not rapid pain control needed for a procedure like venipuncture. EMLA, for maximum effectiveness, must be applied approximately 60 minutes before the procedure, making it less suitable for immediate pain relief required for intravenous line placement.

Correct Answer: C

Rationale: Hypertonic solutions can damage tissues if they leak from the vein due to infiltration. It is crucial to monitor for this complication to prevent severe tissue damage. Infiltration is not solely related to the activity level of VLBW infants; it can occur due to various reasons such as vein condition, catheter placement, and fluid type. Continuous infusion pumps may not always detect infiltration, as they typically alarm for pressure changes but not all infiltration instances. Checking the infusion site regularly, preferably hourly, is essential to prevent complications like tissue damage from extravasations, fluid overload, and dehydration.

Correct Answer: B

Rationale: Being persistent through 10 to 15 minutes of food refusal is recommended to help increase caloric intake in infants with FTT. Establishing a routine and using developmental stimulation can also be helpful, but the priority is ensuring adequate caloric intake.

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.
