Which of the following is NOT appropriate first aid for a suspected ear injury?

The choice to put ear drops into an injured ear is not appropriate first aid for a suspected ear injury. Ear drops are generally used to treat conditions such as ear infections or to soften wax, but they can cause further irritation or complications if there is an injury, particularly if the eardrum is perforated. Introducing any type of fluid into the ear canal without proper medical evaluation can exacerbate the injury or lead to complications such as infection.

In contrast, applying a clean bandage to the ear can help protect the area from further injury or infection, especially if there is bleeding. Encouraging the person to lie down can help stabilize them and prevent additional trauma or discomfort, especially if they are feeling dizzy or unstable. Seeking prompt medical attention is critical to properly evaluate the extent of the injury and initiate appropriate treatment.
