CNA Exam: Safety & Emergency Procedures

Comprehensive Study Guide


---


Overview


Safety and emergency procedures are among the most critical competencies tested on the CNA exam. This guide covers fire safety protocols, fall prevention strategies, restraint use guidelines, emergency response techniques, infection control, and general patient safety principles. Mastery of these concepts is essential not only for passing the exam but for protecting patients and yourself in real clinical settings.

🔥 Fire Safety


Summary

In a healthcare setting, fire safety protocols are strictly ordered to prioritize patient rescue above all else. CNAs must memorize two key acronyms — RACE and PASS — and understand the rationale behind each step.


RACE Protocol (Fire Emergency Response)

| Step | Action | Details |

|------|--------|---------|

| R | Rescue | Remove patients in immediate danger FIRST |

| A | Alarm | Activate the fire alarm SECOND |

| C | Contain/Confine | Close doors and windows to slow fire spread |

| E | Extinguish/Evacuate | Use extinguisher if safe; otherwise evacuate |


PASS Technique (Fire Extinguisher Use)

  • • P — Pull the pin
  • • A — Aim at the base of the fire (not the flames)
  • • S — Squeeze the handle
  • • S — Sweep side to side

    • Evacuation Priority Order

    1. Patients in immediate danger (closest to fire)

    2. Ambulatory patients (they can move themselves)

    3. Non-ambulatory patients (require assistance or equipment)


    Key Terms

  • • RACE — Fire emergency response sequence
  • • PASS — Fire extinguisher operation technique
  • • Contain — Closing doors/windows to slow fire and smoke spread

    • Why Closed Doors Matter

    > A closed door can withstand fire for 20–30 minutes, giving staff critical time to evacuate patients safely. Doors act as fire barriers, slowing the spread of both fire and toxic smoke.


    ⚠️ Watch Out For

  • • The exam may try to trick you: Rescue comes BEFORE activating the alarm — patient safety is always the first priority
  • • Aim the extinguisher at the base of the fire, never the flames
  • • Do not use elevators during a fire evacuation

    🚶 Fall Prevention


    Summary

    Falls are one of the most common causes of patient injury in healthcare settings. CNAs play a primary role in identifying fall risks and implementing preventive measures. When a fall occurs, the CNA's response must follow a specific protocol to prevent further harm.


    Fall Risk Reduction Strategies

  • • Keep bed in the lowest position when not providing direct care
  • • Ensure patients wear non-skid footwear (rubber-soled shoes or non-slip socks)
  • • Use bed exit alarms for high-risk patients
  • • Keep call lights within reach at all times
  • • Clear pathways of clutter and ensure adequate lighting

    • When a Patient Starts to Fall

    Do NOT try to stop the fall completely — this can injure both patient and CNA.


    ✅ Correct Response:

    1. Guide the patient to the floor in a controlled manner

    2. Protect the patient's head

    3. Lower yourself with them using proper body mechanics


    After a Patient Falls — Immediate Steps

    1. Do NOT move the patient

    2. Assess for injuries (visible wounds, pain complaints)

    3. Call the nurse immediately — stay with the patient

    4. The nurse must assess before the patient is moved

    5. Complete an incident report


    Key Terms

  • • Bed exit alarm — Device that alerts staff when a high-risk patient attempts to leave the bed unassisted
  • • Non-skid footwear — Shoes or socks with slip-resistant soles to reduce fall risk
  • • Fall risk assessment — Evaluation of patient factors that increase likelihood of falling

    • ⚠️ Watch Out For

  • • Never attempt to catch or hold up a falling patient — guide them down safely instead
  • • The nurse must assess the patient before they are moved, even if the patient appears fine
  • • All four side rails raised = considered a restraint (see Restraint section)
  • • Bare feet and regular socks (without non-slip soles) are fall hazards

    • ---


    🔒 Restraint Use


    Summary

    Restraints are highly regulated in healthcare due to the potential for harm. CNAs must never apply restraints without a physician's written order and must monitor restrained patients frequently to prevent complications including impaired circulation, skin breakdown, and psychological distress.


    Requirements Before Applying a Restraint

  • • Must have a physician's or licensed provider's written order
  • • Restraints cannot be applied based solely on CNA judgment
  • • Less restrictive alternatives must have been considered first

    • Monitoring Requirements for Restrained Patients

    Every 30 minutes, assess:

  • • ✅ Circulation (check pulse, skin color, temperature)
  • • ✅ Skin condition under restraint
  • • ✅ Offer repositioning
  • • ✅ Offer toileting
  • • ✅ Provide range-of-motion exercises

    • Proper Restraint Application

    | Rule | Reason |

    |------|--------|

    | Two fingers must fit between restraint and skin | Prevents impaired circulation |

    | Tie to movable bed frame, never side rails | Prevents injury when rail is lowered |

    | Always use a quick-release knot | Enables rapid removal in emergency |


    Quick-Release Knot Types

  • • Clove hitch
  • • Slip knot

    • > ❌ Standard knots are NEVER acceptable — they cannot be released quickly in an emergency


    When All Four Side Rails = A Restraint

    Raising all four side rails (upper and lower) is classified as a physical restraint and requires a physician's order. This is a frequently tested exam concept.


    Key Terms

  • • Physical restraint — Any device that restricts a patient's movement and cannot be easily removed by the patient
  • • Quick-release knot — A knot designed for rapid removal in emergencies
  • • Movable bed frame — The frame portion that moves when the bed is adjusted (vs. fixed frame or side rails)

    • ⚠️ Watch Out For

  • • CNAs cannot apply restraints without a written order — this is a legal and safety boundary
  • • Tying restraints to side rails is dangerous — always tie to the bed frame
  • • Monitoring must happen at least every 30 minutes, not every hour
  • • Raising all four side rails requires an order — this is frequently confused on the exam

    • ---


    🚨 Emergency Response


    Summary

    CNAs must respond quickly and correctly during life-threatening emergencies including cardiac arrest, choking, and severe bleeding. Knowing the CNA's specific role — and its limits — is essential for both the exam and patient safety.


    Cardiac Arrest Response

    CNA's Role:

    1. Call for help — activate the emergency response system

    2. Begin CPR if trained and no pulse is present

    3. Retrieve the AED

    4. The nurse takes over medical management


    Adult CPR Ratios

    | Component | Standard |

    |-----------|----------|

    | Compression-to-breath ratio | 30:2 |

    | Compression rate | 100–120 per minute |

    | Compression depth | At least 2 inches |


    DNR (Do Not Resuscitate) Orders

    A DNR means CPR and resuscitation are NOT initiated.


    The CNA MUST still:

  • • Call the nurse immediately
  • • Remain with the patient
  • • Provide comfort measures
  • • Offer emotional support to family

    • > ⚠️ A DNR does NOT mean abandoning the patient — comfort and presence remain essential.


    Choking — Heimlich Maneuver

    Used for: Conscious choking victim with complete airway obstruction


    Abdominal thrust placement:

  • • Above the navel
  • • Well below the breastbone
  • • Delivered with firm inward and upward thrusts

    • Severe Bleeding (Hemorrhage) Response

    1. Apply direct pressure with a clean cloth or gloved hand

    2. Maintain continuous pressure — do not remove cloth

    3. If cloth becomes saturated, add more material on top (do not lift the first layer)

    4. Call for the nurse immediately


    Key Terms

  • • AED (Automated External Defibrillator) — Device used to deliver an electrical shock to restore normal heart rhythm during cardiac arrest
  • • DNR (Do Not Resuscitate) — A legal medical order directing healthcare providers not to perform CPR
  • • Heimlich maneuver — Abdominal thrust technique used to dislodge a foreign body from the airway
  • • Hemorrhage — Severe, life-threatening blood loss

    • ⚠️ Watch Out For

  • • Even with a DNR, the CNA must call the nurse and stay with the patient
  • • Compressions must be at least 2 inches deep — shallow compressions are ineffective
  • • For choking, the Heimlich is only used for complete airway obstruction; partial obstructions are managed differently
  • • Never remove the original cloth from a bleeding wound — add on top to preserve clotting

    🧤 Infection Control & Safety


    Summary

    Proper use of Personal Protective Equipment (PPE), safe handling of sharps, and correct response to exposure incidents are critical safety responsibilities for CNAs. The order of donning and doffing PPE is designed to prevent self-contamination.


    Donning (Putting ON) PPE — Correct Order

    1. Gown (first — protects clothing/body)

    2. Mask or Respirator

    3. Goggles or Face Shield

    4. Gloves (last — because they are most contaminated during removal)


    Doffing (Removing) PPE — Correct Order

    1. Gloves (first — most contaminated)

    2. Goggles or Face Shield

    3. Gown

    4. Mask or Respirator (last — protects face from airborne particles until the end)


    > 🔑 Memory tip: Think of it this way — gloves touch everything, so they come OFF first. The mask is closest to your airway, so it comes OFF last.


    Needlestick Injury — Immediate Response

    1. Remove gloves

    2. Wash the puncture site thoroughly with soap and water

    3. Report immediately to supervisor

    4. File an incident report

    5. Arrange medical follow-up (possible exposure evaluation/prophylaxis)


    Safe Sharps Disposal

  • • Dispose immediately after use in a puncture-resistant sharps container
  • • Never recap needles
  • • Never bend or break needles
  • • Never place sharps in regular trash or linen bags

    • Latex Allergy Protocol

    When a patient has a documented latex allergy:

  • • Use only latex-free gloves and equipment
  • • Maintain a latex-free environment
  • • Alert the nurse immediately
  • • Document per facility policy

    • Key Terms

  • • PPE (Personal Protective Equipment) — Protective gear including gloves, gown, mask, and eye protection
  • • Sharps container — Puncture-resistant, leak-proof container for needle/lancet disposal
  • • Isolation room — Room used to contain infectious patients and prevent pathogen spread
  • • Incident report — Official documentation of an unexpected event affecting patient or staff safety

    • ⚠️ Watch Out For

  • • The order of PPE removal matters — wrong order leads to self-contamination
  • • Gloves go on last and come off first — this trips up many students
  • • After a needlestick, wash with soap and water — do not squeeze or suck the wound
  • • Recapping needles is never acceptable — it significantly increases needlestick risk

    🏥 General Patient Safety


    Summary

    General patient safety encompasses the broader practices CNAs use daily to prevent harm, including safe patient handling, understanding restraint classifications, recognizing sentinel events, and responding appropriately to allergy information.


    Safe Patient Handling

    Before transferring any patient, assess:

  • • Patient's weight
  • • Patient's mobility level
  • • Patient's ability to assist

    • Then use:

  • • Mechanical lift equipment
  • • Assistive transfer devices
  • • Assistance from other staff members

    • > ❌ Manual lifting of patients should be avoided — it is a leading cause of CNA back injuries


    Side Rail Safety

    | Side Rail Position | Classification | Order Required? |

    |-------------------|---------------|-----------------|

    | Upper 2 rails raised | Positioning aid | No |

    | All 4 rails raised | Physical restraint | Yes — physician's order |


    Sentinel Events

    A sentinel event is defined as:

    > An unexpected occurrence involving death or serious physical or psychological injury to a patient


    Required response:

  • • Immediate reporting
  • • Facility investigation
  • • System-level analysis to prevent recurrence

    • Key Terms

  • • Safe patient handling — Protocols and equipment used to move/transfer patients safely without manual lifting
  • • Sentinel event — Unexpected serious patient harm or death requiring immediate investigation
  • • Latex allergy — Allergic reaction to natural rubber latex; requires latex-free care environment
  • • Mechanical lift — Equipment (e.g., Hoyer lift) used to safely transfer patients

    • ⚠️ Watch Out For

  • • All four side rails = restraint — this requires a physician's order (frequently tested!)
  • • Latex allergies require both latex-free gloves AND equipment — not just gloves
  • • A sentinel event requires immediate investigation, not routine reporting
  • • Safe patient handling applies to all transfers, not just heavy patients
