Exam 4: Control of Microorganisms

After using the phone,the laboratory tech sprayed the receiver with a chemical spray.This process will kill a defined scope of microorganisms.What is this process called?

The best way to care for your back is to prevent back injuries.All of the following are some ways to prevent back injuries EXCEPT:

Why should health care workers wash their hands after coming into contact with a patient?

High-level disinfectants are active against all the following EXCEPT:

Autoclaves use this method to sterilize inanimate objects.

The three types of alcohol used as an effective skin antiseptic include all the following EXCEPT:

This topical antiseptic disrupts the microbial cell membrane and precipitates the cellular contents.

This compound is a diphenyl ether,and it exerts its bactericidal effects by disrupting the cell wall.It has good activity against gram-positive cocci,but poor activity against fungi.What is its name?

For the most effective microbial killing,all iodophors must be properly diluted because:

Engineering controls and work practice controls to ensure Standard Precautions are followed include all the following EXCEPT:

The purpose of surgical hand scrubs and waterless hand rubs is to:

These disinfectants are cationic,surface-activated agents that work by reducing the surface tension of molecules in a liquid,resulting in the disruption of the cellular membrane of microbes.

This organization regulates chemical skin antiseptics.

To ensure the electrical safety of laboratory personnel,the College of American Pathologists (CAP)requires these checks annually.

Laboratory Safety for Hazardous Chemicals includes:

When using disinfectants,it is important to follow the manufacturer's instructions for diluting the product because if it is not diluted properly:

The main goal of handwashing is to:

In the Laboratory Response Network (LRN)program,hospital-based microbiology laboratories are classified as this type of laboratory.

Once bioterrorism is suspected,a sentinel laboratory should perform all culture manipulation using these safety guidelines.

These two alcohols are effective in killing hepatitis B virus (HBV).
