Correct answer: C — Review hearing protection, alarm audibility, exposure controls and refer if indicated

A deterioration on surveillance should trigger review of exposure controls, hearing protection fit, training and referral pathways. Difficulty hearing alarms suggests the control strategy may be poorly matched to the task. Waiting for the next routine test misses prevention opportunities. Permanent removal may be unnecessary if exposure can be properly controlled.
