Why emergency response is a tested domain

Medical offices, clinics, and urgent cares encounter emergencies — anaphylaxis, chest pain, respiratory distress, syncope, seizures, and cardiac arrest. The NHA CCMA exam content outline includes emergency response and basic life support (BLS) as a clinical skill domain. The exam tests the candidate's ability to recognize an emergency, activate the emergency response system, initiate BLS, and support the provider's management of the crisis.

This post covers the BLS algorithm for adults, children, and infants; the common office emergencies; the emergency equipment the CCMA must know; and the exam's favorite questions on each.

BLS algorithm (current AHA guidelines)

Basic Life Support (BLS) follows the American Heart Association's (AHA) chain of survival and the CAB sequence (Circulation, Airway, Breathing) for CPR.

Adult BLS (one rescuer)

1. Scene safety — confirm the scene is safe for the rescuer and the victim.
2. Recognition of cardiac arrest — tap the victim, shout, look for normal breathing. No response, no breathing or only gasping — cardiac arrest.
3. Activate emergency response — call 911, request an AED.
4. Check pulse at the carotid artery. If no pulse within 10 seconds, begin CPR.
5. Compressions — heel of one hand on the lower sternum (center of the chest), heel of the other hand on top, fingers interlocked, arms straight, shoulders directly over the hands. Compress at least 2 inches (5 cm) deep, at a rate of 100 to 120 per minute. Allow full chest recoil between compressions. Minimize interruptions.
6. Airway and breathing — after 30 compressions, open the airway with a head-tilt, chin-lift. Give 2 rescue breaths, each over 1 second, watching for chest rise.
7. AED — turn on the AED as soon as it is available. Apply the pads to the victim's bare chest (right upper chest below the collarbone, left side below the armpit). Follow the AED's voice prompts. Resume CPR immediately after shock (or after AED analysis if no shock is advised).

Compression-to-ventilation ratio: 30:2 for single rescuer adult CPR.

Child and infant BLS (one rescuer)

• For children (1 to puberty), use one or two hands for compressions, depth about 2 inches.
• For infants (under 1 year), use two fingers (single rescuer) or two-thumb encircling hands (two rescuers), depth about 1.5 inches.
• Compression-to-ventilation ratio: 30:2 for single rescuer, 15:2 for two rescuers.

Choking

• Conscious adult or child — Heimlich maneuver (abdominal thrusts) until the object is expelled or the victim becomes unresponsive.
• Pregnant or obese victim — chest thrusts instead of abdominal thrusts.
• Conscious infant — five back blows alternating with five chest thrusts, supporting the infant face-down on the forearm.

When the victim becomes unresponsive, lower them to the ground, activate EMS, and begin CPR. Each time you open the airway to give breaths, look in the mouth for the obstructing object. If you see it, remove it. Do not perform a blind finger sweep.

Common office emergencies

Anaphylaxis

A severe, life-threatening allergic reaction. Causes include medications, foods, latex, insect stings. Signs and symptoms:

• Skin: hives, flushing, itching, angioedema (swelling of lips, tongue, face).
• Respiratory: wheezing, stridor, hoarseness, difficulty breathing, tightness in the throat.
• Cardiovascular: hypotension, tachycardia, syncope, shock.
• Gastrointestinal: nausea, vomiting, diarrhea, abdominal pain.

Management:

1. Activate emergency response. Call 911.
2. Administer epinephrine 0.3 to 0.5 mg IM (adult) or 0.01 mg/kg IM (pediatric) in the mid-anterolateral thigh. The CCMA may administer from an EpiPen or epinephrine vial per the provider's order and standing protocol.
3. Position the patient supine with legs elevated (unless respiratory distress is severe — then the patient may prefer to sit up).
4. Administer oxygen.
5. Monitor vital signs.
6. Consider a second dose of epinephrine every 5 to 15 minutes if symptoms persist.
7. Transport to the emergency room. Anaphylaxis can recur (biphasic reaction) hours after the initial episode.

Asthma exacerbation

Signs: wheezing, cough, shortness of breath, use of accessory muscles, inability to speak in full sentences, cyanosis (late). Peak flow is reduced.

Management:

1. Position the patient sitting upright (leaning forward if more comfortable).
2. Administer oxygen.
3. Administer a short-acting beta-2 agonist (albuterol) via nebulizer or inhaler — 2 to 4 puffs, repeated every 20 minutes for the first hour if needed.
4. Administer oral corticosteroids per the provider's order (reduces airway inflammation, but onset is delayed).
5. Monitor vital signs and peak flow.
6. Transport to the emergency room if symptoms do not improve.

Chest pain (suspected acute coronary syndrome)

Signs: substernal chest pressure, squeezing, or heaviness; pain radiating to the arm, neck, jaw, or back; diaphoresis; nausea; shortness of breath; lightheadedness.

Management:

1. Activate emergency response. Call 911.
2. Position the patient sitting or semi-Fowler's if tolerated, or supine if hypotensive.
3. Administer oxygen if SpO2 is below 94%.
4. Obtain a stat EKG and notify the provider immediately. The CCMA may not interpret the EKG, but they may hand the tracing to the provider.
5. Administer aspirin (chewable, 162 to 325 mg) per the provider's order, unless the patient has an aspirin allergy or recent GI bleeding.
6. Establish IV access if trained and permitted.
7. Administer nitroglycerin per the provider's order if the patient is not hypotensive and has no recent erectile dysfunction medication use (sildenafil, tadalafil).
8. Monitor vital signs and document the time of onset, the description of pain, the interventions, and the response.

The CCMA's role is supportive — they activate the response, perform the actions within their training, and document. The provider directs the medical management.

Syncope

A transient loss of consciousness with spontaneous recovery, usually from cerebral hypoperfusion. Causes include vasovagal response, orthostatic hypotension, cardiac arrhythmia, dehydration, hypoglycemia, and seizure (post-ictal state).

Management:

1. Lay the patient flat and elevate the legs (if no spinal injury suspected).
2. Loosen tight clothing.
3. Assess airway, breathing, and circulation.
4. Obtain vital signs.
5. If the patient does not regain consciousness within a minute, activate emergency response.
6. Consider glucose — perform a fingerstick glucose if the patient is not fully alert.
7. Document the event, including any symptoms before the syncope and the time of recovery.

Seizure

A sudden, uncontrolled electrical disturbance in the brain. Tonic-clonic (grand mal) seizures involve loss of consciousness, stiffening (tonic phase), and rhythmic jerking (clonic phase). Most seizures last 1 to 3 minutes and stop spontaneously.

Management during the seizure:

1. Stay calm. Time the seizure.
2. Protect the patient's head from injury. Do not restrain the patient.
3. Do not put anything in the patient's mouth. The tongue cannot be swallowed.
4. Loosen tight clothing around the neck.
5. Position the patient on the side (if possible) to allow drainage of saliva.
6. Move sharp objects and furniture away.

Management after the seizure:

1. Position the patient on their side (post-ictal position).
2. Check airway, breathing, and circulation.
3. Obtain vital signs.
4. Perform a fingerstick glucose if hypoglycemia is suspected.
5. Allow the patient to rest. Reorient them slowly as they recover.
6. Activate emergency response if the seizure lasts more than 5 minutes, recurs without recovery, or is a first-time seizure.

Status epilepticus is a seizure lasting more than 5 minutes or recurrent seizures without recovery between them. This is a medical emergency requiring IV benzodiazepines (lorazepam, midazolam, diazepam) administered by the provider or EMS.

Hypoglycemia

Blood glucose below 70 mg/dL. Symptoms include sweating, tremor, hunger, confusion, irritability, and (severe) loss of consciousness or seizure.

Management:

1. If the patient is conscious and able to swallow, give 15 to 20 grams of fast-acting carbohydrate (4 oz of juice or regular soda, glucose tablets, hard candy).
2. Recheck glucose in 15 minutes. Repeat the carbohydrate if still below 70 mg/dL.
3. Once the glucose is above 70 mg/dL, give a snack with protein and complex carbohydrate if the next meal is more than an hour away.
4. If the patient is unconscious or unable to swallow, do not give anything by mouth. Activate emergency response. The provider may administer IV dextrose or IM glucagon.

The CCMA must know the patient's history and identify the risk factors for hypoglycemia (insulin or sulfonylurea use, missed meal, increased activity).

Emergency equipment the CCMA must know

Crash cart

The office or clinic maintains a crash cart with emergency medications and equipment. The CCMA must know its location and contents. Standard contents include:

• Defibrillator (AED or manual) with pads in adult and pediatric sizes.
• Airway equipment — bag-valve mask (BVM), oxygen mask, nasal cannula, suction, oral and nasal airways.
• Medications — epinephrine 1:1000 and 1:10,000, atropine, nitroglycerin, aspirin, albuterol, diphenhydramine, methylprednisolone, dextrose 50%, glucagon, naloxone, normal saline.
• IV equipment — catheters, tubing, fluids, syringes, needles.
• Cardiac monitor if available.

The CCMA checks the crash cart at least daily for readiness (sealed, equipment present, defibrillator charged) and after every use.

Oxygen

The CCMA must know how to set up oxygen, choose the appropriate delivery device, and adjust the flow rate:

• Nasal cannula — 1 to 6 L/min. Provides 24 to 44% FiO2.
• Simple face mask — 5 to 10 L/min. Provides 35 to 60% FiO2. Must be at least 5 L/min to prevent CO2 retention.
• Non-rebreather mask — 10 to 15 L/min. Provides 60 to 80% FiO2. The reservoir bag must be inflated before placing the mask.
• Bag-valve mask (BVM) — used for assisted ventilation. Squeeze the bag once every 5 to 6 seconds for adults, once every 2 to 3 seconds for children and infants. The CCMA must be certified to use a BVM.

Suction

The CCMA sets up suction and clears the airway as needed. Suction should be available at every emergency.

Activating the emergency response system

The exam tests that the CCMA knows when and how to activate EMS:

• Call 911 (or the local emergency number).
• Provide the address and the nature of the emergency.
• Stay on the line until the dispatcher hangs up.
• Send someone to the entrance to direct the EMS team.
• Continue care until EMS arrives.

The CCMA does not delay activation to ask unnecessary questions, does not hang up before EMS has the address, and does not wait for the provider to authorize the call when the situation is clearly an emergency.

Documentation of an emergency

The CCMA documents:

• The time of the event and the time of the response.
• The patient's presentation (signs, symptoms, vital signs).
• The interventions performed and the time of each.
• The patient's response to each intervention.
• The provider's orders and the patient's response.
• The time of EMS arrival and the unit's name.
• The patient's condition at transfer.

The documentation is completed as soon as practical after the patient has been stabilized or transferred. The CCMA may also complete an incident report (which is separate from the medical record).

The exam's favorite emergency response questions

Question type 1: "A patient is unconscious and not breathing. What is the first action?" — Answer: activate the emergency response system (call 911), get an AED, and begin CPR.

Question type 2: "An adult patient collapses in the waiting room. Two rescuers are available. What is the compression-to-ventilation ratio?" — Answer: 30:2.

Question type 3: "A patient with a known peanut allergy develops hives and difficulty breathing after eating. What is the first medication?" — Answer: epinephrine, administered intramuscularly in the mid-anterolateral thigh.

Question type 4: "A patient having a seizure has food in their mouth. What is the correct action?" — Answer: do not put anything in the patient's mouth. After the seizure stops, position the patient on their side to allow drainage.

A practical closing note

Emergencies are the test of every CCMA skill in a single moment. The exam rewards the candidate who knows the BLS algorithm, recognizes the common office emergencies, and responds with discipline. The field rewards the CCMA who stays calm, activates the response, performs the skills within their scope, and supports the provider.

Maintain your BLS certification. Practice the emergency scenarios. Review the crash cart. The CCMA who owns emergency response owns the safety of every patient in a crisis.
