When administering ear drops to a 2-year-old, the nurse:

Pulls the lobe up & back.

Instructs the parents to hold the child upright for 10 minutes.

Pulls the pinna down and back.

Massages the tragus for 2 minutes before administering the drops.

Answer and Explanation

The Correct Answer is C

Choice A rationale

Pulling the lobe up and back is the correct technique for administering ear drops to adults and children older than three years of age. This maneuver straightens the ear canal in older individuals due to the anatomical development and orientation of the Eustachian tube and external auditory meatus.

Choice B rationale

Instructing parents to hold the child upright for 10 minutes is an appropriate post-administration instruction to facilitate medication absorption and prevent spillage. However, this action is not part of the physical technique for correctly preparing the ear canal for drop instillation.

Choice C rationale

For children under 3 years old, the external auditory canal is straighter and angled differently than in adults. Pulling the pinna down and back straightens this shorter, more upwardly curved canal, allowing the medication to flow more effectively and reach the tympanic membrane for optimal absorption.

Choice D rationale

Massaging the tragus after instillation helps to distribute the medication throughout the ear canal and facilitate its passage deeper. However, massaging the tragus before administering the drops does not contribute to straightening the ear canal and is not a preparatory step for instillation.

Step 2: F = (38.5 × 9 ÷ 5) + 32.

Step 3: F = (346.5 ÷ 5) + 32.

Step 4: F = 69.3 + 32.

Step 5: F = 101.3 °F. The patient's temperature in Fahrenheit is 101.3 °F.
