Question 1

Which of the following is an example of a fomite in the healthcare setting?

Accepted Answer

A stethoscope carrying bacteria between patients

Answer

A fomite is an inanimate object that can carry and transfer infectious agents, and stethoscopes are a classic example in clinical environments.

Question 2

Standard precautions apply to which of the following?

Accepted Answer

All blood, body fluids, and non-intact skin regardless of diagnosis

Answer

Standard precautions are applied universally to all patients to reduce transmission risk regardless of known or suspected infection status.

Question 3

What does the term 'chain of infection' refer to?

Accepted Answer

The sequence of elements required for disease transmission to occur

Answer

The chain of infection describes six links — infectious agent, reservoir, portal of exit, mode of transmission, portal of entry, and susceptible host — that must all be present for infection to spread.

Question 4

Which hand hygiene method is preferred when hands are visibly soiled with blood or body fluids?

Accepted Answer

Soap and water

Answer

Soap and water must be used when hands are visibly soiled because alcohol-based products do not physically remove organic material.

Question 5

A patient is placed on droplet precautions. At what distance from the patient must a surgical mask be worn?

Accepted Answer

3 feet

Answer

Droplet precautions require a surgical mask when working within 3 feet (approximately 1 meter) of the patient, as droplets do not travel far.
