The answer is the cataract. A cataract is a shadowing of the lens in the eye which leads to a decline of vision. Cataracts often progress slowly and can affect one or both eyes. Symptoms may include faded colors, blurry vision, and halos around light, trouble with bright lights, and trouble seeing at night.
A patient who is undergoing intravenous therapy should not perform isometric exercises because it may lead to bleeding and injury at the injection site. During a shower, the patient should protect the injection site and dressing from getting wet by covering it with plastic. Applying pressure with sterile gauze at the injection site if the catheter falls out helps to reduce bleeding. Inflammation and itching at the injection site may be an indication of infection and phlebitis; the patient should report these manifestations immediately.
