Which of the following correctly describes the process of hearing?
Vibration of the eardrum is directly transmitted to the eighth cranial nerve, bypassing the inner ear structures.
Sound waves enter the ear canal and are converted to electrical impulses.
Vibration of the eardrum transmits through the bony ossicles to the perilymph in the inner ear, stimulating the eighth cranial nerve.
Sound is transmitted directly from the eardrum to the brain.
The Correct Answer is C
Choice A rationale
Vibration of the eardrum is not directly transmitted to the eighth cranial nerve, bypassing the inner ear structures. The vibrations from the eardrum are first transmitted through the ossicles (tiny bones in the middle ear) to the cochlea in the inner ear.
Choice B rationale
Sound waves enter the ear canal, but they are not directly converted to electrical impulses. The sound waves cause the eardrum to vibrate, and these vibrations are transmitted through the ossicles to the cochlea, where they are converted into electrical signals that are sent to the brain via the eighth cranial nerve.
Choice C rationale
Vibration of the eardrum transmits through the bony ossicles to the perilymph in the inner ear, stimulating the eighth cranial nerve. This is the correct description of the process of hearing.
Choice D rationale
Sound is not transmitted directly from the eardrum to the brain. The sound-induced vibrations of the eardrum are transmitted through the ossicles to the cochlea, where they are converted into electrical signals that are sent to the brain via the eighth cranial nerve.

Choice C rationale
While electrolyte imbalance can occur with enteral feeding, diluting the formula is not typically done to resolve this issue.
Choice D rationale
Delayed gastric emptying is not typically resolved by diluting enteral feeding formula.

Purulent drainage is thick and opaque. It can have a yellow, tan, green, or brown color and is a sign of infection.
Choice B rationale
Sanguineous drainage is bright red and indicates active bleeding3.
Choice C rationale
Serosanguineous drainage is typically pink-red and thin. It is made up of blood and serous fluid and is typically seen in a normal, non-infected wound3.
Choice D rationale
Serous drainage is clear and thin, like the fluid from a blister3.
