Nearsightedness or myopia is a condition that causes a client to say, “I can’t see things far away?”. This is because the point of focus is in front of the retina, making distant objects appear blurry.
Choice A. Blindness is wrong because it means the complete loss of vision in one or both eyes.
A blind person cannot see anything, near or far.
Choice B. Farsightedness is wrong because it means the opposite of nearsightedness. Farsightedness or hyperopia is a condition that causes a client to see distant objects clearly, but sees near objects as blurry. This is because the point of focus is behind the retina, making close objects appear blurry.
Choice C. Astigmatism is wrong because it is not a condition that affects the distance of vision, but the shape of the cornea. Astigmatism is an irregularity in the curve of the cornea, which can affect both near and distant vision. A person with astigmatism may see objects as distorted or blurry at any distance.

Superficial wound healing.
Cellular contact inhibition is important in this process because it prevents cells from migrating and proliferating excessively when the wound is closed. Contact inhibition is a cell property that limits the migration and proliferation of cells in crowded environments.
Choice A is wrong because sweat production does not involve contact inhibition. Sweat glands secrete sweat through ducts that open onto the skin surface.
Choice C is wrong because scoliosis development does not involve contact inhibition. Scoliosis is a condition that causes the spine to curve sideways, and it can be caused by genetic, environmental, or unknown factors.
Choice D is wrong because tyrosinase production does not involve contact inhibition.
Tyrosinase is an enzyme that catalyzes the production of melanin, a pigment that gives color to the skin, hair, and eyes.
