MULTIPLE CHOICE
| a. | “Systemic agents are not affected by wound exudates.” |
| b. | “Systemic agents penetrate to the site of infection.” |
| c. | “Topical agents can damage inflamed or abraded tissues.” |
| d. | “Topical agents work only against established local infections.” |
ANS: D
Topical antiseptics are not used to treat established local infections. Systemic agents are more effective, because they are not affected by wound exudates. They penetrate to the site of infection, and they do not damage inflamed or abraded tissues.

| a. | A patient with a systemic infection |
| b. | A patient with a medium-sized abscess |
| c. | A patient who has a wound with moderate exudate |
| d. | A patient who needs to have wounds cleansed for prophylaxis |
ANS: D
Antiseptics are useful as prophylaxis; when applied properly, they can help cleanse wounds and reduce microbial contamination. A patient with a systemic infection is treated with a systemic anti-infective drug. An abscess must be incised and drained, and a topical agent cannot significantly penetrate the skin to be effective. A wound with moderate exudates requires antibiotic therapy.

| a. | “Applying hexachlorophene to the operative site preoperatively will help prevent infection.” |
| b. | “It is important to ensure that all surgical instruments have been sterilized appropriately.” |
| c. | “Operating room personnel should all perform a presurgical scrub with antimicrobial soap.” |
| d. | “Preventing contamination by microorganisms in the environment is the most important perioperative measure.” |
ANS: A
Although bathing a patient’s skin area with antiseptic agents reduces the number of surface bacteria, this measure has not been shown to reduce the incidence of postoperative infection. Disinfecting 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.

| a. | Disinfecting the bedpan with an antiseptic solution |
| b. | Using antibacterial hand soap when washing the hands |
| c. | Using an alcohol-based hand rub after each patient contact |
| d. | Wearing gloves while caring for the patient |
ANS: B
All of these measures are appropriate for this patient; however, using an antibacterial hand soap is the most important, because only an antimicrobial soap is effective against a spore-forming bacterium, such as B. anthracis.
