A visitor from Poland who does not speak English seems to be somewhat apprehensive about the nurse examining his neck. How should the nurse proceed that would allow the patient to feel more comfortable with the nurse examining his thyroid gland?

A. Loss of the outer hair on the eyebrows attributable to a decrease in hair follicles: It is normal for older adults to experience changes in hair growth, including loss of eyebrow hair due to a decrease in hair follicles. This finding is considered a typical age-related change and not abnormal.

B. Unequal pupillary constriction in response to light: This finding is considered abnormal and may indicate a potential neurological issue or damage to the optic or oculomotor nerves. Normal pupillary response should be equal and reactive to light, so any discrepancy in pupillary constriction warrants further evaluation.

C. Decrease in tear production: A decrease in tear production is common in older adults due to age-related changes in lacrimal gland function. This condition, known as dry eye syndrome, is not considered abnormal for this age group.

D. Presence of arcus senilis observed around the cornea: Arcus senilis is characterized by a gray or white ring around the cornea due to lipid deposits and is commonly seen in older adults. While it may indicate elevated cholesterol levels in younger individuals, its presence in elderly patients is usually not abnormal.

A. Nystagmus in extreme superior gaze: A few beats of nystagmus in extreme lateral gaze may be normal, but sustained nystagmus, especially in superior gaze, suggests neurological impairment such as vestibular dysfunction or multiple sclerosis.

B. Slight amount of lid lag when moving the eyes from a superior to an inferior position: Lid lag, where the upper eyelid lags behind the downward movement of the eye, is often associated with hyperthyroidism (e.g., Graves' disease). It is not a normal finding in the diagnostic positions test.

C. Convergence of the eyes: Convergence is assessed when a person focuses on a near object, such as during an accommodation test. The diagnostic positions test evaluates extraocular muscle function and cranial nerves III, IV, and VI, focusing on coordinated movement rather than convergence.

D. Parallel/synchronized movement of both eyes: The normal finding in the diagnostic positions test is smooth, coordinated movement of both eyes in all six cardinal directions without lagging, misalignment, or significant nystagmus. This indicates intact extraocular muscles and proper cranial nerve function.
