Question 2

A patient with varicella (chickenpox) requires which combination of isolation precautions?

Accepted Answer

Airborne and contact precautions

Answer

Varicella spreads via both airborne droplet nuclei and direct contact with vesicular lesions, so both airborne and contact precautions are required simultaneously.

Question 3

Which of the following is a work practice control for reducing bloodborne pathogen exposure?

Accepted Answer

Never pipetting blood by mouth

Answer

Never pipetting blood by mouth is a work practice control — a behavioral change in how tasks are performed — rather than an engineering or PPE control.

Question 4

The hepatitis B vaccination series is recommended for phlebotomy students and new employees because hepatitis B virus (HBV):

Accepted Answer

Can survive on environmental surfaces for up to 7 days

Answer

HBV is highly stable and can survive on dry environmental surfaces at room temperature for at least 7 days, making occupational exposure risk significant without vaccination.

Question 5

A phlebotomist collects blood from a patient on droplet precautions due to influenza. Which PPE must be worn at minimum?

Accepted Answer

Gloves and a surgical mask

Answer

Droplet precautions require a surgical mask (in addition to Standard Precautions such as gloves) when working within 3 feet of the patient; an N95 is only required for airborne precautions.
