The healthcare provider prescribes ear drops to an adult client with an ear infection. Which teaching should the nurse provide?

Choice A reason: Cooling the bottle is not necessary and shaking it is only required if the instructions specify to do so to mix the medication. Choice B reason: Inserting the tip of the dropper into the ear canal is not recommended as it can introduce bacteria and cause injury. Choice C reason: Pulling the pinna up and back in adults helps to straighten the ear canal, allowing for proper delivery of the medication. Choice D reason: Administering the drops with the head held upright is not the correct method; the head should be tilted to allow the drops to flow down into the ear canal.
