Correct Answer: C

Rationale: For severe postoperative pain, a preventive around-the-clock schedule is necessary to prevent decreased plasma levels of medications. Providing only an opioid analgesic at this time may not be sufficient for effective pain management. Increasing the dosage without an order is unsafe and may lead to oversedation. Planning a preventive schedule of pain medication around the clock ensures consistent pain relief and better management. Giving the child a clock and explaining when they can have pain medications may increase the child's focus on waiting for relief rather than addressing the pain promptly, making it a less effective strategy.

Correct Answer: B

Rationale: The correct answer is B: Guided imagery. Guided imagery is an effective distraction technique for adolescents as it helps them focus on positive mental images instead of the pain. This technique can be a powerful tool in managing pain and anxiety during procedures. Blowing bubbles (choice A) may be more suitable for younger children as it can engage them visually and help distract them. EMLA cream (choice C) is a topical anesthetic and not a distraction technique. Sucrose solution (choice D) is used for pain relief in infants, not typically for adolescents undergoing painful procedures.

Correct Answer: D

Rationale: Obesity increases the risk for conditions like asthma, hypertension, dyslipidemia, and altered glucose metabolism, but not typically irritable bowel disease.

Correct Answer: A

Rationale: The correct answer is A: Cephalocaudal. The cephalocaudal pattern of development means that growth and motor control proceed from the head downward through the body. This explains why infants can raise their heads before they can sit and gain control of their trunks before walking. Choices B, C, and D are incorrect. Anterior to posterior refers to development from the front to the back, while proximodistal refers to development from the center of the body outward. Normal growth curve charts are used to track physical growth over time and are not directly related to the directional pattern of development in infants.

Correct Answer: B

Rationale: Egocentricity in children aged 2 to 7 years means they are unable to see things from another person's perspective. This characteristic is a normal part of their cognitive development during this stage. Choice A, 'Selfishness,' is not an accurate description as egocentricity is more about a limited ability to understand others' viewpoints rather than intentional selfishness. Choice C, 'Able to put self in another's place,' is incorrect as egocentric children struggle to do this. Choice D, 'Prefers to play alone,' is not directly related to egocentricity but may be a behavior exhibited by some children for various reasons.
