RMA First Aid and Emergency Procedures 1 — Questions and Answers

Question 1: A patient collapses in the waiting room and is unresponsive with no normal breathing. What is the FIRST action the medical assistant should take?

Begin chest compressions immediately
Call for help and activate the emergency response system (call 911) (Correct answer)
Check for a pulse for 10 seconds before starting CPR
Retrieve the AED from the wall mount

Correct answer: Call for help and activate the emergency response system (call 911)

The first priority when an unresponsive patient is found is to call for help and activate the emergency response system (dial 911 or call a code), then begin CPR and retrieve the AED.

According to American Heart Association (AHA) guidelines for BLS (Basic Life Support), when encountering an unresponsive victim: first ensure scene safety, then tap the patient's shoulders and shout 'Are you OK?' to confirm unresponsiveness. If unresponsive and not breathing normally, immediately call for help/activate EMS (911), send someone for the AED, and begin high-quality CPR (30 compressions : 2 breaths at 100–120 compressions/min with at least 2-inch depth for adults). The faster defibrillation is available, the better the survival outcome — time to first shock is the most important factor in VF/VT cardiac arrest. Medical assistants must maintain current CPR/AED certification.

Question 2: Which of the following is a sign of anaphylaxis that requires immediate administration of epinephrine?

Mild localized itching at the site of a bee sting
Generalized urticaria (hives), throat tightness, and difficulty breathing after eating (Correct answer)
A mild rash that develops 2 days after starting a new antibiotic
Nausea and upset stomach after eating spicy food

Correct answer: Generalized urticaria (hives), throat tightness, and difficulty breathing after eating

Generalized hives combined with throat tightness and difficulty breathing after an exposure are classic signs of anaphylaxis — a severe, life-threatening allergic reaction requiring immediate intramuscular epinephrine.

Anaphylaxis is a severe, rapid-onset systemic allergic reaction caused by massive histamine and mediator release from mast cells. Signs and symptoms include: skin (urticaria, angioedema, flushing), respiratory (bronchospasm, stridor, throat tightness, dyspnea), cardiovascular (hypotension, tachycardia, syncope), and gastrointestinal (nausea, vomiting, cramping). Epinephrine auto-injector (EpiPen) 0.3mg IM to the lateral thigh is the treatment of choice and must be given immediately — antihistamines (diphenhydramine) are adjunct, not primary treatment. Medical assistants must recognize anaphylaxis, have epinephrine and emergency supplies readily available in clinical areas, and call 911 even after epinephrine administration.

Question 3: What is the correct compression-to-ventilation ratio for adult CPR with a single rescuer?

15:2
30:2 (Correct answer)
5:1
100:0 (compressions only)

Correct answer: 30:2

Current AHA guidelines recommend a 30:2 compression-to-ventilation ratio for single-rescuer adult CPR — 30 chest compressions followed by 2 rescue breaths.

The 30:2 CPR ratio is the standard for both lay and healthcare provider single-rescuer adult CPR per AHA guidelines. Chest compressions must be: delivered at a rate of 100–120 per minute, to a depth of at least 2 inches (5 cm) but no more than 2.4 inches (6 cm), allowing full chest recoil between compressions, and with minimal interruptions. Each rescue breath should be given over 1 second, causing visible chest rise. If the rescuer is unwilling or unable to provide rescue breaths, hands-only (compression-only) CPR is acceptable and effective. For infants and children, the ratio remains 30:2 for single rescuers, changing to 15:2 for two healthcare provider rescuers in pediatric settings.

Question 4: A patient in the medical office develops syncope (fainting). After ensuring they have not injured themselves, what is the most appropriate initial action?

Immediately call 911 for any fainting episode
Have the patient sit up quickly to restore consciousness
Position the patient supine with legs elevated (Trendelenburg-like position) to improve cerebral blood flow (Correct answer)
Administer ammonia inhalants immediately to stimulate breathing

Correct answer: Position the patient supine with legs elevated (Trendelenburg-like position) to improve cerebral blood flow

For simple vasovagal syncope, positioning the patient supine (lying flat) with legs elevated increases venous return to the heart and improves blood flow to the brain, typically restoring consciousness quickly.

Syncope (fainting) is typically caused by a transient reduction in cerebral blood flow. The most common type in medical offices is vasovagal syncope, triggered by emotional stress, pain, the sight of blood, prolonged standing, or venipuncture. Immediately lay the patient flat and elevate the legs 12–15 inches to redirect blood toward the central circulation. Loosen any tight clothing, ensure airway is open, and monitor vital signs. Most patients recover within minutes. If the patient does not regain consciousness promptly, or if syncope occurred without warning or is recurrent, call 911 as it may indicate a more serious cardiac or neurological event. Ammonia inhalants are no longer recommended as a routine intervention.

Question 5: When treating a patient with an arterial bleed from a laceration on the forearm, which method of hemorrhage control should be used first?

Apply a tourniquet above the elbow immediately
Apply direct pressure with a clean or sterile cloth or bandage (Correct answer)
Elevate the arm and wait for spontaneous clot formation
Apply ice to the wound to constrict blood vessels

Correct answer: Apply direct pressure with a clean or sterile cloth or bandage

Direct pressure applied firmly to the wound is the first and most effective method for controlling active external bleeding, including arterial bleeds, before considering other measures.

Direct pressure is the primary method for controlling external hemorrhage. Apply firm, continuous pressure with a clean or sterile dressing material over the wound. Do not remove the dressing to look at the wound — if blood soaks through, add more dressings on top and continue pressing. For extremity wounds that do not respond to direct pressure, a tourniquet (placed 2–3 inches above the wound) may be indicated. Elevation of the limb above heart level and pressure on the proximal feeding artery are adjunct measures. In the medical office, emergency hemorrhage control is a critical skill for medical assistants, who must know the location of emergency supplies and know when to call 911.

Question 6: Which of the following is the correct procedure when a medical assistant suspects a patient is experiencing a stroke?

Give the patient aspirin and observe for 30 minutes before calling 911
Use the FAST acronym to assess symptoms and call 911 immediately (Correct answer)
Have the patient rest and schedule an urgent appointment with a neurologist
Check the patient's blood pressure and administer antihypertensive medication

Correct answer: Use the FAST acronym to assess symptoms and call 911 immediately

When stroke is suspected, the medical assistant should use the FAST assessment (Face drooping, Arm weakness, Speech difficulty, Time to call 911) and immediately activate emergency medical services without delay.

Stroke is a medical emergency in which every minute of delayed treatment causes additional irreversible brain damage ('time is brain'). The FAST acronym is used for rapid stroke recognition: Face drooping (ask the patient to smile — is it uneven?), Arm weakness (ask patient to raise both arms — does one drift down?), Speech difficulty (is speech slurred, confused, or absent?), Time to call 911 immediately. Medical assistants should NOT attempt to treat the patient but should call 911, keep the patient calm and still, note the time symptoms began (critical for thrombolytic therapy eligibility — tPA must be given within 4.5 hours), and prepare to relay all information to EMS. Aspirin should NOT be given without physician direction.
