What strategies are effective for reducing the risk of tissue necrosis following injection?
What will be an ideal response?
Four strategies are effective in reducing the risk of tissue necrosis following injections. They include:
1. Avoid epinephrine concentrations of 1:50,000, especially in confined tissues.
2. Avoid excessive durations of topical anesthetic contact as recommended in the product instructions.
3. Avoid excessive blanching by allowing sufficient time for solution to diffuse into tissue during deposition; tissues should not turn "stark white" in appearance.
4. Avoid extensive distention of tissues by allowing sufficient time for solution to diffuse while depositing; tissues should not bulge or "balloon" with too much solution.

Answer the following statement(s) true (T) or false (F)
1. When the head moves, fluids known as perilymph and endolymph in the semicircular canals and vestibule move, activating equilibrium receptors that send the information along vestibular nerves to the cerebrum for interpretation. 2. The external ear initiates sound conduction by collecting sound waves and channeling them to the tympanic membrane, making it vibrate. The vibrations, in turn, are amplified by the ossicles of the inner ear. 3. Movements of the hairs of the cochlea caused by sound waves trigger nerve impulses that are transmitted by the auditory nerve to the brain, where they are perceived as sound. 4. As we age, the semicircular canals in the inner ear become less sensitive to changes in position, and this reduced sensitivity affects balance. 5. Changes that occur with aging include shrinking of the eardrum and degeneration of the joints between the bones of the middle ear, so they do not move as freely.
