Certified Clinical Medical Assistant Exam Practice Question

Correct Answer: C

Rationale: Option C is the best choice as washing hands with soap and water during dressing changes is a fundamental practice that effectively reduces the spread of infection. Proper hand hygiene minimizes the transfer of pathogens.

Option A is incorrect; applying disinfectant directly on the dressing can lead to irritation and does not ensure the area is sterile.

Option B is misleading; iodine should be applied to the skin before the dressing change, not to the hands afterward, as this does not prevent contamination during the procedure.

Option D is also incorrect; gloves should be worn throughout the dressing change to protect both the patient and the medical assistant from infection.
