A nurse is assessing cranial nerve VIII.
What tests will be administered on the client?

Choice A rationale

The Whisper test evaluates hearing acuity, while the Romberg test assesses balance and proprioception by having the client stand with feet together and eyes closed. Both tests involve sensory assessments but do not directly assess cranial nerve VIII, which is the vestibulocochlear nerve responsible for hearing and balance.

Choice B rationale

PERRLA (pupils equal, round, reactive to light and accommodation) assesses cranial nerves II and III, while EOMs (extraocular movements) assess cranial nerves III, IV, and VI. These tests do not evaluate cranial nerve VIII.

Choice C rationale

Snellen and Rosenbaum tests measure visual acuity for distance and near vision, respectively. These tests assess cranial nerves II and III but do not evaluate cranial nerve VIII.

Choice D rationale

The Rinne and Weber tests are audiometric assessments that specifically evaluate cranial nerve VIII, which controls hearing and balance. The Rinne test compares air and bone conduction of sound, while the Weber test assesses sound lateralization, making them appropriate tests for assessing cranial nerve VIII.

Choice A rationale

Myopia, or nearsightedness, is when distant objects appear blurry because light rays focus in front of the retina. A Snellen exam result of 20/50 means the client can see at 20 feet what someone with normal vision sees at 50 feet, indicating reduced distance vision. However, this condition does not correlate with the ability to read the Rosenbaum chart, which is for near vision, thus excluding myopia.

Choice B rationale

Normal vision is not indicated by a Snellen exam result of 20/50, as this signifies a visual impairment where the client sees at 20 feet what a person with normal vision sees at 50 feet. Normal vision would be indicated by 20/20 on the Snellen exam.

Choice C rationale

Presbyopia is the age-related loss of the eye's ability to focus on near objects, typically noticeable in people over 40. Although this condition involves difficulty reading at close range, the client's uncorrected Snellen exam result of 20/50 pertains to distance vision, which differentiates presbyopia from the given scenario.

Choice D rationale

Hyperopia, or farsightedness, is when close objects appear blurry because light rays focus behind the retina. The client's ability to read the Rosenbaum chart without difficulty indicates good near vision, while the Snellen exam result of 20/50 reflects reduced distance vision, thus supporting the diagnosis of hyperopia.
