A nurse is teaching a nursing student how to care for patients in the perioperative period. Which statement by the student about preventing postoperative infections indicates a need for further teaching?
a. "Applying hexachlorophene to the opera-tive site preoperatively will help prevent infection."
b. "It is important to ensure that all surgical instruments have been sterilized appro-priately."
c. "Operating room personnel should all perform a presurgical scrub with antimi-crobial soap."
d. "Preventing contamination by microor-ganisms in the environment is the most important perioperative measure."
A
Although bathing a patient's skin area with antiseptic agents reduces the number of surface bac-teria, this measure has not been shown to reduce the incidence of postoperative infection. Disin-fecting surgical instruments, antimicrobial surgical scrubbing for operating room personnel, and disinfection of other surfaces in the environment have been shown to be effective measures for preventing postoperative infection.
