Certified Clinical Medical Assistant Exam Practice Question
Which of the following uses steam under pressure to ensure surgical instruments are sterile?
Correct Answer: B
Rationale: An autoclave utilizes steam under pressure to achieve sterilization, effectively killing bacteria, viruses, and spores on surgical instruments. This process ensures that instruments are safe for use in medical procedures.
Option A, ultrasound, is a diagnostic tool that uses sound waves, not steam, and does not sterilize instruments. Option C, scrubbing, involves physically cleaning but does not guarantee sterilization. Option D, sanitization, reduces the number of microorganisms but does not achieve complete sterility like an autoclave does. Thus, only the autoclave meets the rigorous standards required for surgical instrument sterilization.
