3. What needs to be considered in choosing chemical antisepsis agents?
A. Removes soil, debris, natural skin oil, hand lotion and microorganism from the dermisDecreases the number of microorganism on the skin to an irreducible minimum Keeps the population of microorganisms minimal during the operative procedure by suppression of growth Reduces the hazard of microbial contamination
B. Broad-spectrum antimicrobial agent
Fast-acting and effective
Non-irritating
Prolonged action in preventing the growth of microorganism
C. Mild and paraben-free Have little or no residual effect on the skinMost rapid and greatest reduction of microorganisms No surfactant or foaming action
D. Scrub sinks should be located adjacent to OR for convenience and safety reasonsScrub sinks should be knee or foot-operated to reduce contamination risks Scrub sinks are deep and wide enough to prevent splashbackScrub sinks are designated as single-use for scrubbing and handwashing and not to be used for clearing…
