Which cranial nerve is responsible for muscles that move the eye and lids?
Oculomotor.
Vestibulocochlear.
Facial.
Trigeminal.
The Correct Answer is A
Choice A rationale
The oculomotor nerve (cranial nerve III) is responsible for innervating the muscles that move the eye and lift the eyelid, as well as controlling pupil constriction and lens shape for focusing.
Choice B rationale
The vestibulocochlear nerve (cranial nerve VIII) is involved in hearing and balance, not in the movement of eye muscles or eyelids.
Choice C rationale
The facial nerve (cranial nerve VII) controls muscles of facial expression, taste sensations from the anterior two-thirds of the tongue, and functions in tear and saliva production.
Choice D rationale
The trigeminal nerve (cranial nerve V) is responsible for sensation in the face and motor functions such as biting and chewing, not for eye movements.

Correct Answer is D
Explanation
Choice A rationale
Interactive dressings are designed to interact with the wound environment to promote healing. These can include dressings that release medication or create an optimal moisture balance. They are not typically used for acutely inflamed and oozing skin lesions.
Choice B rationale
Passive dressings are protective covers that keep the wound clean and protected from external contaminants. They do not have additional properties to manage wound exudate or inflammation.
Choice C rationale
Protective dressings are generally used to shield wounds from further injury or contamination. They do not specifically address the needs of an oozing and inflamed lesion.
Choice D rationale
Occlusive dressings are designed to maintain a moist wound environment, which can aid in the healing of oozing wounds. They can also provide a barrier to external contaminants and help manage exudate effectively, making them suitable for acutely inflamed and oozing lesions.
