Ulcerative colitis is a chronic inflammatory bowel disease that causes diarrhea, pain, and bleeding in the colon. Stress and certain foods can trigger or worsen the symptoms, so it is important to teach the mother how to help her son cope with stress and avoid triggers.

Choice A is wrong because ulcerative colitis is not an infectious disease that can spread to others.

Choice B is wrong because ulcerative colitis causes diarrhea, not constipation. Nutritional guidance is important, but not the main focus of teaching.

Choice C is wrong because the daily use of enemas is not part of the treatment plan for ulcerative colitis. Enemas can irritate the colon and cause more inflammation.

A brilliant, uniform red reflex in both eyes is a sign of a healthy retina and optic nerve. The red reflex is the reflection of light from the retina that varies in color depending on the patient’s skin tone. It can be seen by holding the ophthalmoscope directly in front of your eye and asking the patient to focus on a point in the distance.

Choice B is wrong because an abnormal finding would be an absent or asymmetric red reflex, which could indicate cataracts, retinal detachment, or other eye diseases.

Choice C is wrong because a possible visual defect would not affect the red reflex, but rather the visual acuity or field of vision of the patient.

A vision screening would involve testing the patient’s ability to read letters or numbers at different distances.

Choice D is wrong because small hemorrhages would not cause a brilliant, uniform red reflex, but rather dark spots or blotches on the retina that can be seen with the ophthalmoscope.

Hemorrhages can be caused by diabetes, hypertension, or trauma.
