What is characteristic of a neonate's vision?
- A. Pupils react to light
- B. Tear glands function
- C. Blink reflex is absent
- D. Ciliary muscles are mature
Correct Answer: A
Rationale: The correct answer is A: 'Pupils react to light.' Newborns' pupils do react to light, indicating that the visual pathway is functioning. However, a neonate's vision is still developing, and they can only focus on objects close to their face. Choice B is incorrect because tear glands are functional at birth. Choice C is incorrect because the blink reflex is present in neonates and helps protect their eyes. Choice D is incorrect as neonates' ciliary muscles are not fully developed.
What approach is the most appropriate when performing a physical assessment on a toddler?
- A. Demonstrate the use of equipment
- B. Perform traumatic procedures last
- C. Use minimum physical contact initially
- D. Always proceed systematically in a head-to-toe direction
Correct Answer: C
Rationale: The most appropriate approach when performing a physical assessment on a toddler is to use minimum physical contact initially. This helps gain the toddler's cooperation and reduces their distress. Performing traumatic procedures last is crucial as they are likely to upset the child and should be handled with care. Demonstrating the use of equipment may be complex for toddlers to understand, so it is not the most appropriate initial approach. Proceeding systematically in a head-to-toe direction is a good practice but using minimum physical contact initially is more important to establish trust and cooperation with the toddler.
