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.

Correct Answer is ["24"]
Explanation
Step 1 is: To find out how many mL/hr the IV pump should be set to deliver, we need to set up a proportion with the prescribed units of heparin on one side and the available units of heparin on the other side. So, the calculation is: (1,200 units/hr ÷ 25,000 units) × 500 mL = 24 mL/hr.
Therefore, the IV pump should be set to deliver 24 mL/hr.
Correct Answer is D
Explanation
Choice A rationale
Granulation tissue forming at the bottom of the wound bed is a characteristic of secondary intention healing, not primary intention. In secondary intention, the wound is left open and fills with granulation tissue.
Choice B rationale
A wound that was contaminated at the time of injury would likely require secondary intention healing to allow for cleaning and observation of the wound. This is not typical of primary intention healing.
Choice C rationale
Prolonged healing of the wound is not a characteristic of primary intention healing. In primary intention, the wound edges are brought together (approximated), which allows for rapid healing.
Choice D rationale
In primary intention healing, the skin edges of the wound are sutured closed. This is the most distinctive feature of primary intention healing, as it allows for minimal scar formation and quick healing.
