Verified step by step guidance

Understand the anatomy of the ear: The pinna is the outer part of the ear, and its position can affect how ear drops are administered effectively.

Consider the age of the child: In children under the age of 3, the ear canal is straighter and shorter, which affects the technique used for administering ear drops.

For a 7-year-old child, the ear canal is more developed, similar to adults, so the technique involves pulling the pinna up and back to straighten the ear canal.

Explain the purpose of the technique: Pulling the pinna up and back helps to straighten the ear canal, allowing the ear drops to flow directly into the ear without obstruction.

Ensure comfort and safety: When administering ear drops, make sure the child is in a comfortable position, and explain the procedure to them to reduce anxiety.
