Emergency Management, First Aid & Office Preparedness
Key Takeaways
- The 2026 CMA (AAMA) outline lists 20 emergency conditions a medical assistant must recognize and respond to, from cardiac arrest to chemical exposure.
- Adult CPR uses a compression rate of 100-120/min, a depth of at least 2 inches (5 cm), and a 30:2 compression-to-ventilation ratio for one or two rescuers.
- Insulin shock (hypoglycemia) comes on fast with cold, clammy skin; diabetic ketoacidosis (hyperglycemia) develops slowly with warm, dry skin and fruity breath.
- Control external bleeding with direct pressure first; elevate and apply a tourniquet only if pressure fails on a limb.
- Treat suspected shock by laying the patient supine, maintaining body heat, and not giving anything by mouth while alerting the provider and EMS.
Emergency Management & Basic First Aid
Section I.B.8 (Safety and Emergency Procedures) and I.B.9 (Emergency Management, Identification, and Response/Basic First Aid) of the 2026 CMA (AAMA) content outline require you to recognize an emergency, take an appropriate first action within your scope, and activate help. A medical assistant does not diagnose or treat independently — but you are often the first person to see a deteriorating patient.
The General Response Sequence
For almost every office emergency, follow the same opening steps before condition-specific care:
- Ensure scene safety — remove the hazard or move the patient if staying is dangerous.
- Assess responsiveness — tap and shout; check for normal breathing.
- Activate the emergency response — call out for help, alert the provider, and call EMS (911) for life threats.
- Apply the ABCs — Airway open, Breathing adequate, Circulation present.
- Provide first aid within scope and stay with the patient.
- Document the event, times, interventions, and the patient's response afterward.
CPR and Cardiac/Respiratory Arrest
| Parameter | Adult | Child (1 yr-puberty) | Infant (<1 yr) |
|---|---|---|---|
| Compression rate | 100-120/min | 100-120/min | 100-120/min |
| Compression depth | At least 2 in (5 cm) | About 2 in (5 cm) | About 1.5 in (4 cm) |
| Hand placement | 2 hands, lower sternum | 1-2 hands, lower sternum | 2 fingers / 2 thumbs |
| Ratio (single rescuer) | 30:2 | 30:2 | 30:2 |
| Ratio (two rescuers) | 30:2 | 15:2 | 15:2 |
Attach an AED as soon as it arrives, follow the voice prompts, and minimize interruptions to compressions. Push hard, push fast, and allow full chest recoil between compressions.
Recognizing and Responding to Specific Emergencies
The outline names roughly 20 conditions. Memorize the single most important first action for each — that is how the exam frames "what should the medical assistant do FIRST?" items.
| Emergency | Key recognition signs | First action (within MA scope) |
|---|---|---|
| Foreign body airway (choking) | Clutching throat, unable to speak/cough | Conscious adult: abdominal thrusts (Heimlich) |
| Cardiac/respiratory arrest | Unresponsive, no normal breathing | Start CPR, attach AED, call EMS |
| Syncope (fainting) | Pale, dizzy, brief loss of consciousness | Lower to supine, elevate legs, monitor airway |
| Shock | Cold/clammy skin, weak rapid pulse, low BP | Lay supine, keep warm, NPO, call EMS |
| Seizure | Convulsions, loss of awareness | Protect from injury, do not restrain, time it, nothing in mouth |
| Anaphylaxis | Hives, swelling, wheeze, hypotension | Assist with epinephrine, call EMS, supine with legs up |
| Insulin shock (hypoglycemia) | Sudden onset, cold clammy skin, shaky, confused | Give fast sugar if alert; if not, EMS |
| Diabetic ketoacidosis (hyperglycemia) | Slow onset, warm/dry skin, fruity breath, deep breathing | Alert provider, EMS for severe cases |
| External bleeding | Visible hemorrhage | Direct pressure; tourniquet on limb if uncontrolled |
| Burns | Redness, blistering, charring | Cool with water (not ice), cover loosely, no ointments |
| Fractures/dislocations | Deformity, swelling, pain | Immobilize as found, ice, do not realign |
| Sprains/strains | Pain, swelling, limited motion | RICE: Rest, Ice, Compression, Elevation |
| Poisoning | History of ingestion, altered status | Call Poison Control (1-800-222-1222), save container |
| Cerebrovascular accident (CVA/stroke) | FAST: Face droop, Arm weakness, Speech, Time | Note time of onset, call EMS immediately |
| Head trauma | LOC, confusion, unequal pupils | Stabilize, monitor neuro status, EMS |
| Heat exhaustion/stroke | Heavy sweat vs hot dry skin, confusion | Cool the patient; heat stroke is an EMS emergency |
| Cold exposure/hypothermia | Shivering, confusion, low temp | Move to warmth, remove wet clothing, warm gradually |
| Hyperventilation | Rapid breathing, tingling, anxiety | Coach slow breathing, reassure, rule out cause |
| Asthma attack | Wheeze, dyspnea, accessory muscle use | Assist with rescue inhaler, sit upright, monitor |
| Lacerations/avulsions/punctures | Open wound, bleeding | Control bleeding, clean, dress, assess tetanus status |
Exam traps
- Insulin shock vs DKA: "fast and cold" = too little sugar (hypoglycemia); "slow and warm with fruity breath" = too much sugar (DKA). When unsure and the patient is alert, give sugar — it helps hypoglycemia and only mildly worsens hyperglycemia.
- Seizures: never restrain the patient or put anything in the mouth; protect the head and time the seizure.
- Burns: use cool water, never ice or butter; ice can deepen tissue injury.
- Shock and arrest patients are NPO — never give food or fluids.
Office Emergency Preparedness
The Crash Cart
Every clinical office maintains a crash cart — a sealed, mobile unit of emergency supplies checked on a documented schedule (often each shift or weekly) and resealed with a numbered, breakable lock so tampering is obvious.
| Crash cart contents | Purpose |
|---|---|
| AED/defibrillator | Restore organized rhythm in cardiac arrest |
| Oxygen + delivery devices | Support oxygenation |
| Airway supplies (oral airways, BVM, suction) | Maintain a patent airway |
| Emergency drugs (epinephrine, atropine, dextrose, naloxone) | Provider-directed treatment |
| IV supplies and fluids | Vascular access/volume |
| Documentation/code sheet | Record interventions and times |
The MA's role is to keep the cart stocked, in-date, and checked, and to bring it to the patient — drugs are administered under provider direction.
Fire, Evacuation & Disaster Planning
- RACE for a fire: Rescue anyone in danger, Alarm (pull/call), Contain (close doors), Extinguish or Evacuate.
- PASS to use an extinguisher: Pull the pin, Aim at the base, Squeeze the handle, Sweep side to side.
- Know the office evacuation routes, assembly point, and how to assist patients with mobility limitations.
- Maintain written plans for fire, severe weather, power loss, and active-threat events; staff should drill periodically.
Body Mechanics & Incident Reporting
Good body mechanics prevent staff injury during transfers: keep a wide base, bend the knees (not the back), keep the load close, and push rather than pull. Any emergency, injury, near-miss, or unsafe condition is documented on an incident/patient-safety variance report, which is a risk-management record kept separate from the patient's chart and is not referenced in the medical record.
