A nurse is educating the parent of an 18-month-old toddler on how to administer otic drops. Which of the following parent statements indicates an understanding of the teaching?

Choice A rationale The external auditory canal in a toddler is shorter and has an upward curve compared to an adult. Pulling the pinna down and back straightens this canal, allowing the medication to flow more effectively and reach the eardrum. This maneuver optimizes drug delivery by aligning the auditory canal for better access and absorption. This is a crucial anatomical consideration for medication administration in young children. Choice B rationale Inserting the dropper into the ear canal can cause significant trauma to the delicate tympanic membrane or the canal walls. The dropper tip may be sharp or firm, and forceful insertion can lead to pain, bleeding, or perforation of the eardrum. This action is contraindicated as it poses a significant risk of injury to the child's auditory structures. The drops should be instilled just inside the opening. Choice C rationale Administering cold ear drops can cause a caloric reaction, leading to dizziness, nausea, and vertigo. The sudden temperature change stimulates the vestibular system in the inner ear, causing a temporary imbalance. The drops should be warmed to body temperature by holding the container in the hands for a few minutes before administration to prevent this adverse physiological response. Choice D rationale Massaging the area behind the ear, over the mastoid bone, can be painful and is not an effective method for distributing otic medication. The drops are meant to act locally within the ear canal. Gentle pressure on the tragus, the small cartilage flap in front of the ear canal, can help to push the medication deeper into the canal after instillation, but massaging behind the ear is not indicated.
