• The pt who is under observation for chest pain

• The patient who has been admitted for dehydration

• The patient admitted for stabilization of atrial fibrillation

In the chain of infection:

• The host leaves the portal of exit to enter the reservoir

• The infectious agent enters host through portal of entry

• The infectious agent leaves host by the mode of transmission

• The portal of entry and portal of exit are always different

The patient is under routine precautions. You plan to take vital signs & your hands are not visibly soiled. For hand hygiene, you:

• Use alcohol-based hand sanitizer before and after touching the patient

• Wash with soap and water for 10-20 sec before touching the patient

• The mode of transmission

• The portal of exit

• Susceptible hosts

The killing or removal of all microorganisms, including bacterial spores, is called:

• Disinfection
• Cleaning
• Sterilization
• Wiping

Individuals who can transmit a disease but do not show symptoms of the disease are known as 

• immunosuppressed
• carriers
• incubators
• saprophytes
