What is the primary principle behind Standard Precautions?

Accepted Answer

Treat all blood, body fluids, and non-intact skin/mucous membranes as potentially infectious, regardless of the patient's known diagnosis.

Question 2

Which transmission-based precaution category requires a phlebotomist to wear a fit-tested N95 respirator when entering a patient's room?

Accepted Answer

Airborne Precautions, used for pathogens spread via small droplet nuclei such as Mycobacterium tuberculosis, measles, and varicella.

Question 3

A patient is diagnosed with MRSA. Which transmission-based precaution level should the phlebotomist follow?

Accepted Answer

Contact Precautions, requiring gloves and a gown upon entering the patient's room to prevent spread via direct or indirect contact.

Question 4

For which type of pathogen transmission would a surgical mask (not an N95) be the minimum recommended respiratory protection for a phlebotomist?

Accepted Answer

Droplet Precautions, for pathogens like influenza or meningitis that travel in large respiratory droplets typically within 3–6 feet.

Question 5

What is the correct order for DONNING (putting on) PPE before entering an isolation room?
