Question 1 of 5
The nurse read the patient's health history and noted cranial nerve III oculomotor paralysis. Which of the following would the nurse expect?
Correct Answer: C
Rationale: The correct answer is C because cranial nerve III controls the muscles that lift the eyelid (ptosis) and constrict the pupil.
Therefore, with oculomotor paralysis, ptosis will be evident (drooping eyelid) and there will be no pupillary constriction.
Choice A is incorrect because cranial nerve III paralysis affects eye movement, not the ability to look to the outside.
Choice B, myopia, is unrelated to cranial nerve III function.
Choice D, normal eye movement, is incorrect as oculomotor paralysis affects eye movements.
