點耳藥水（Ear drops）的正確技術旨在拉直外耳道（External auditory canal），以便藥液能順利流向鼓膜。成人外耳道呈向上、向後彎曲，故需將耳廓（Pinna）向上、向後拉。若藥水溫度過低，可能刺激內耳前庭引發眩暈（Vertigo），故應將藥水回溫至室溫。點藥時應置於耳道口，不可將滴管深入耳道，以防造成物理性傷害。
To straighten the adult ear canal for effective medication delivery, the nurse should pull the pinna upward and backward. This maneuver aligns the canal, allowing drops to flow easily toward the tympanic membrane without causing trauma.
