Phlebotomy Test Safety and Infection Control 2

Question 1

Which type of isolation precaution is required for a patient diagnosed with active pulmonary tuberculosis?

Accepted Answer

Airborne precautions

Answer

Airborne precautions are required for TB because the bacteria are transmitted via tiny droplet nuclei that remain suspended in the air.

Question 2

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

Accepted Answer

Gown, mask, eye protection, gloves

Answer

CDC guidelines specify gown first, then mask/respirator, then eye protection, then gloves last so gloves cover the gown cuffs.

Question 3

A phlebotomist sustains a needlestick injury while drawing blood from an HCV-positive patient. What is the first action to take?

Accepted Answer

Immediately wash the site with soap and water

Answer

Immediate washing with soap and water for at least 15 seconds is the first response to a needlestick to reduce pathogen load.

Question 4

Which disinfectant concentration of sodium hypochlorite (bleach) is recommended by the CDC for decontaminating blood spills?

Accepted Answer

1:10 dilution (approximately 5,000 ppm)

Answer

A 1:10 dilution of household bleach provides approximately 5,000 ppm of available chlorine, which is effective for blood spill decontamination.

Question 5

Which of the following actions violates standard precautions when drawing blood?

Accepted Answer

Recapping a used needle by holding the cap with the other hand

Answer

Two-handed recapping is prohibited under standard precautions because it significantly increases the risk of needlestick injury.
