Workers in a textile unit report ringing in the ears after each shift. Which preventive measure should the occupational health nurse emphasise?
Correct answer: A. Reduce noise exposure and use correctly fitted ear protection
- A. Reduce noise exposure and use correctly fitted ear protection
- B. Use cotton in the ears only when ringing becomes severe
- C. Take analgesics before each shift to prevent hearing loss
- D. Increase the machine speed so work finishes earlier
Explanation
Repeated loud-noise exposure can cause permanent sensorineural hearing loss, so reducing the source and using suitable hearing protection are important controls. Cotton and analgesics do not adequately protect hearing, and increasing machine speed may worsen exposure.
