Final answer:
Normal assessment findings for cranial nerve III, the oculomotor nerve, include smooth tracking of a visual target, conjugate eye movements, proper convergence and accommodation, and the absence of internuclear ophthalmoplegia.
Step-by-step explanation:
Normal assessment findings for cranial nerve III, also known as the oculomotor nerve, would include the ability to track the tip of a pen through the visual field without any difficulty. This includes smooth, coordinated movements of the eyes, known as conjugate movements, which are essential for proper function of the extraocular muscles and gaze stabilization. During the exam, the patient's eyes should converge (both eyes turn towards the nose) when the pen is moved toward the face, and there should be a change in the shape of the lens, known as accommodation, to maintain focus on the approaching object. An absence of internuclear ophthalmoplegia, which manifests as double vision (diplopia) when one eye fails to move in harmony with the other, is also a sign of normal function.
