Which compound can be used to treat localized skin infections and to irrigate wounds?
a. Benzalkonium chloride (BAC)
b. Hexachlorophene (pHisoHex)
c. Oxychlorosene sodium (Clorpactin WCS90)
d. Sodium hypochlorite
ANS: C
Oxychlorosene sodium can be used to treat localized infections caused by drug-resistant microbes and to irrigate wounds. Benzalkonium chloride can cause severe local injury, so it is not widely used. Hexachlorophene has central nervous system (CNS) effects when absorbed through the skin and is not used in open areas such as wounds. Sodium hypochlorite is too irritating for application to the skin.
