Final answer:
The most beneficial treatment strategy for a patient with a bright red-colored eardrum, distortion of light reflex, and drum hypomobility is to insert tympanostomy tubes into the ear surgically.
Step-by-step explanation:
The patient's symptoms of a bright red-colored eardrum, distortion of light reflex, and drum hypomobility indicate a condition known as chronic otitis media.
The most beneficial treatment strategy for this patient would be to insert tympanostomy tubes into the ear surgically.
This procedure involves creating a small incision in the eardrum and placing a tiny tube to help drain the fluid, relieve pressure, and restore normal ear function.
