Question

control of microbial growth homework please answer the following questions. 1. which of the following types of medical items requires sterilization? a. needles b. bed linens c. respiratory masks d. blood pressure cuffs 2. which of the following is suitable for use on tissues for microbial control to prevent infection? a. disinfectant b. antiseptic c. sterilant d. water 3. which of the following best describes a microbial control protocol that inhibits the growth of molds and yeast? a. bacteriostatic b. fungicidal c. bactericidal d. fungistatic

Explanation:

1. Needles penetrate the skin and enter sterile - body tissues, so they must be sterilized to prevent infection. Bed linens, respiratory masks, and blood - pressure cuffs do not enter sterile tissues and usually require less stringent disinfection.
2. Antiseptics are used on living tissues to prevent infection. Disinfectants are for inanimate objects, sterilants are for complete sterilization of non - living items, and water alone is not sufficient for microbial control on tissues.
3. Fungistatic agents inhibit the growth of fungi (molds and yeast). Bacteriostatic inhibits bacteria, fungicidal kills fungi, and bactericidal kills bacteria.

Answer:

1. A. needles
2. B. antiseptic
3. D. fungistatic
