A nurse examines a patient’s tympanic membranes with an otoscope. The nurse understands the normal tympanic membrane exhibits which normal characteristic?

Choice A reason: A normal tympanic membrane is not white with prominent capillaries. Such an appearance may indicate inflammation or infection (e.g., otitis media), where increased vascularity or opacity occurs, making this an abnormal and incorrect characteristic. Choice B reason: A normal tympanic membrane is pearly gray, slightly translucent, with a visible cone of light reflecting off its taut surface. This reflects healthy middle ear anatomy, with no fluid or inflammation, making this the correct description. Choice C reason: A pulled-in tympanic membrane suggests negative middle ear pressure, often due to eustachian tube dysfunction, not a normal finding. The normal membrane is flat or slightly concave, making this an incorrect characteristic. Choice D reason: Light pink with a slight bulge suggests inflammation or fluid (e.g., otitis media), not a normal tympanic membrane. Normal membranes are pearly gray and flat, not pink or bulging, making this an incorrect description.
