5 True/False questions
Good HDL level → should be higher than 40 mg/dL to help prevent heart disease by carrying bad cholesterol away from the arteries
glaucoma → instrument used for visual examination of the ear; An otoscope is an instrument which is used to look into the ear canal. The ear speculum (a cone-shaped viewing piece of the otoscope) is slowly inserted into the ear canal while looking into the otoscope. The speculum is angled slightly toward the person's nose to follow the canal. A light beam extends beyond the viewing tip of the speculum. The otoscope is gently moved to different angles to view the canal walls and eardrum.
needle stick injury → an accidental puncture caused by a used hypodermic needle, blood borne disease exposure, report immediately, follow blood exposure action plan in facility
low capillary blood glucose, cause? → erythrocyte count; the number of red blood cells per cubic millimeter of blood; performed manually by counting red blood cells under high power magnification on a hemacytometer. Whole blood is diluted with an isotonic solution that prevents lysing of red blood cells; a decrease in red blood cells may indicate anemia, an increase may indicate polycythemia
sensorineural hearing loss: → can be caused by, ototoxic medications
