Question

or other tissue Part 2 True or False (circle one) ITF Since the performance of a disinfectant depends in part upon the degree of microbial contamination, it is faster to disinfect a clean workbench surface than a soiled one. 2. TF The ability of an antimicrobial to kill or inhibit microorganisms depends partly upon the concentration of active ingredients in the solution 3. TF Organic substances such as blood, sputum, and feces bind to many antimicrobial agents, increasing their activity. 4. TF Disinfecting a walk-in cold storage room generally takes longer than disinfecting an equally contaminated, 22° C area. 5. TF The phenol coefficient compares the bactericidal capabilities of test solutions to those of household ammonia. 6. TF In this exercise you perform the phenol coefficient test. 7. TF The phenol coefficient test organism is killed within 10 minutes by a 1:450 dilution of phenol and a 1:300 dilution of test solution. The phenol coefficient of the test solution is 1.5.

Answer 1

Answer:True

(A clean workbench can be easily disinfected because the soiled absorbs most of the disinfectant.)

Answer: True

( The presence of the active ingredient and it's concentration in the solution show action on the microbes)

Answer: True

( This is the reason why the bacterial infection can be easily transfered when a person comes in contact with the infected blood, or bodily fluids.)

Answer: True

( Disinfecting a walk in cold storage room generally takes longer than disinfecting an equally contaminated 22 degree area. )
