A medical assistant is preparing to perform an ear irrigation for a patient with cerumen impaction. Which of the following solutions is generally recommended for softening the cerumen prior to irrigation?
- AIsopropyl alcohol
- BHydrogen peroxide
- CSterile saline
- DCold tap water
Show answer & explanationAnswer & explanation
Correct answer: B. Hydrogen peroxide
Hydrogen peroxide, often diluted, is commonly used to soften cerumen (earwax) due to its effervescent action, which helps to break down and loosen the wax before irrigation.
Why the other options are wrong
- A. Isopropyl alcohol is drying and can irritate the ear canal; it is not used for cerumen softening.
- C. Sterile saline is typically used for irrigation itself, but it is less effective at softening hardened cerumen on its own.
- D. Cold water can cause dizziness and discomfort; warm water is preferred for irrigation, but a softening agent is needed first.

- Hydrogen peroxide is common.
