What is the best action for a nurse after administering ear drops to an adult client?

After administering ear drops to an adult client, gently massaging the tragus of the ear is the most appropriate action. This technique helps promote the distribution of the medication within the ear canal. By massaging the tragus, which is the small flap of cartilage at the entrance of the ear, pressure is applied that can assist in ensuring that the drops are pushed down into the canal, enhancing absorption of the medication.

This approach aligns with best practices for ear medication administration, aimed at maximizing the effectiveness of the treatment. The other options provided would not effectively facilitate the intended function of the ear drops. For example, leaving the client lying with the unaffected ear up does not actively engage the medication in the affected ear. Placing a cotton ball too firmly in the ear can lead to excess pressure and may impede the ear drop solution from properly reaching the tympanic membrane. Similarly, pulling the pinna down and back is not the appropriate technique for adults, as it is typically recommended for children to ensure the ear canal is straightened properly for administration.
