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)

1. Contact precautions require the CNA to wear which additional PPE beyond standard precautions?

  • 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

3. The MOST effective way to prevent the spread of infection in a healthcare setting is:

  • Wearing gloves at all times, including while walking in the hallway
  • Proper hand hygiene (handwashing or alcohol-based hand rub) before and after patient contact
  • Spraying disinfectant in the air every hour
  • Keeping all doors and windows closed

4. When removing personal protective equipment (PPE) after providing care, the CNA should remove the items in which order?

  • Mask first, then gown, then gloves
  • Gloves first, then gown, then mask (or face shield)
  • Gown first, then mask, then gloves
  • All items at once to save time

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
