Which of the following tests could be used to assess the acoustic nerve? (Select All that Apply.)

Forlani

Rinne

Weber

Kinecki

Whisper Test

Audiogram (formal hearing test)

Answer and Explanation

Correct Answer : B,C,E,F

A. Forlani: No known clinical test named "Forlani" is used to assess the acoustic nerve (cranial nerve VIII). Standard assessments for hearing and vestibular function do not include this test, making this an incorrect option.

B. Rinne: The Rinne test evaluates conductive versus sensorineural hearing loss by comparing air conduction and bone conduction using a tuning fork. Normally, air conduction should be greater than bone conduction, but in conductive hearing loss, bone conduction is either equal to or greater than air conduction. It helps assess cranial nerve VIII function and differentiate between middle and inner ear pathology.

C. Weber: The Weber test is another tuning fork test used to differentiate between conductive and sensorineural hearing loss. The tuning fork is placed on the midline of the forehead, and sound should be heard equally in both ears. If sound lateralizes to one ear, it suggests conductive hearing loss in that ear or sensorineural loss in the opposite ear, aiding in the evaluation of cranial nerve VIII.

D. Kinecki: No known clinical test named "Kinecki" is used to assess the acoustic nerve. The main tests for hearing assessment involve tuning forks, spoken-word tests, and audiometry, none of which include a test by this name, making this option incorrect.

E. Whisper Test: The Whisper Test is a simple screening method to assess hearing by whispering words or numbers behind the patient and having them repeat what was heard. This test evaluates the function of cranial nerve VIII by determining whether the patient can perceive soft sounds at a standard distance, providing a quick but effective measure of hearing acuity.

F. Audiogram (formal hearing test): An audiogram is a comprehensive, formal test that measures hearing ability at different frequencies and intensities. It provides detailed information about sensorineural and conductive hearing loss by assessing how well different pitches and volumes are detected, making it one of the most accurate methods for evaluating cranial nerve VIII function.

Correct Answer is A

Explanation

A. Whisper a set of random numbers and letters, and then ask the patient to repeat them: The whispered voice test is a simple and reliable screening method for hearing loss. The nurse stands about 2 feet behind the patient, whispers a series of random numbers or letters, and asks the patient to repeat them. This helps assess high-frequency hearing loss.

B. Shield the lips so that the sound is muffled: While the test is performed without the patient seeing the nurse’s lips to prevent lip reading, deliberately muffling the sound is unnecessary and may alter the accuracy of the assessment.

C. Stand approximately 6 feet away to ensure that the patient can really hear at this distance: The whispered voice test is conducted at a standard distance of about 2 feet, not 6 feet. Increasing the distance may make the test unreliable.

D. Ask the patient to place his or her finger in their ears to occlude outside noise: The test should be performed in a quiet environment, but instructing the patient to occlude their ears is unnecessary. Instead, the nurse tests one ear at a time by covering the opposite ear.

A. Loss of the outer hair on the eyebrows attributable to a decrease in hair follicles B. Unequal pupillary constriction in response to light C. Decrease in tear production D. Presence of arcus senilis observed around the cornea

Correct Answer is B

Explanation

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.
