Q

What is passive natural immunity?

A

Receiving antibodies not from your own immune system.

20
Q

Active artificial immunity comes from?

A

Vaccinations

21
Q

What is passive artificial immunity?

A

Receiving antibodies not from your own immune system, but your immune system doesn’t have to respond.

Q

What are heal care associated infections (HAI’s) aka nosocomial infections?

A

Infections that patients receive which receiving treatment in a health care facility.

36
Q

What is the most effective method for preventing HAI’s?

A
