A nurse is preparing to perform an irrigation to remove a buildup of cerumen from a client's ear. Which of the following actions should the nurse take?

Aim the stream of water directly at the cerumen impaction.

Use cool water to flush the cerumen from the ear canal.

Instill cerumen-softening drops before the irrigation.

Remind the client to use a cotton swab periodically to remove cerumen.

Answer and Explanation

The Correct Answer is C

A. Aim the stream of water directly at the cerumen impaction:
This may injure the tympanic membrane. Irrigation should be directed at the superior wall of the canal.

B. Use cool water to flush the cerumen from the ear canal:
Cool water can cause dizziness or nausea due to stimulation of the vestibular system. Body-temperature water is preferred.

C. Instill cerumen-softening drops before the irrigation:
Softening the cerumen (e.g., with mineral oil or hydrogen peroxide solution) makes irrigation more effective and comfortable.

D. Remind the client to use a cotton swab periodically to remove cerumen:
Cotton swabs can push cerumen deeper and risk damage to the ear canal or drum.
