Why Infection Control & Standard Precautions matters
Infection Control & Standard Precautions is heavily weighted on the CNA Written Examination (NNAAP) because lapses in safety protocols directly threaten patient outcomes.
Sample Practice Questions (5)

- An N95 respirator
- A gown and gloves upon entering the room
- Only a surgical mask
- A plastic apron only
2. A resident is on airborne precautions for suspected tuberculosis. Which type of respiratory protection must the CNA wear?
- A standard surgical mask
- A cloth face covering
- An N95 respirator (or PAPR), and the room should have negative pressure airflow
- No respiratory protection is needed if the door is kept closed

5. A resident on Contact Precautions for MRSA needs a blood pressure check. The CNA should:
- Use the unit's shared blood pressure cuff and return it to the nurses' station after use
- Use dedicated equipment that stays in the resident's room, wearing gloves and gown during the procedure
- Skip the blood pressure check since the resident is in isolation
- Take the blood pressure without gloves since the cuff does not touch broken skin
