Module 1
Module 1: Initial Assessment and Triage
Initial Assessment and Triage
Knowledge check
Q1. What does the 'A' in the primary survey ABCDE approach stand for?
- A. Assessment of breathing
- B. Airway with cervical spine protection ✓
- C. Access to advanced care
- D. Assessment of circulation
Why: The primary survey begins with Airway assessment and maintenance, with cervical spine protection in mind, because an airway obstruction is the most immediate threat to life. Breathing is assessed second (B), and circulation third (C).
Q2. Which triage category is typically assigned to a patient who needs immediate life-saving intervention?
- A. Minor (green)
- B. Delayed (yellow)
- C. Immediate (red) ✓
- D. Expectant (black)
Why: Red or Immediate category patients require immediate life-saving interventions and are treated first. Yellow indicates delayed care, green indicates minor injuries, and black indicates expectant or deceased patients in mass casualty settings.
Q3. What is the normal respiratory rate range for an adult at rest?
- A. 4 to 8 breaths per minute
- B. 12 to 20 breaths per minute ✓
- C. 25 to 35 breaths per minute
- D. 40 to 50 breaths per minute
Why: A normal resting adult respiratory rate is approximately 12 to 20 breaths per minute. Rates below 8 or above 25 are generally considered abnormal and warrant urgent attention, as they may indicate respiratory compromise.
Q4. In the Glasgow Coma Scale, what is the best possible total score?
- A. 10
- B. 12
- C. 15 ✓
- D. 20
Why: The Glasgow Coma Scale ranges from 3 (worst) to 15 (best), combining eye opening (4), verbal response (5), and motor response (6) scores. A score of 8 or less is generally considered severe brain injury.
Q5. Which of the following is a sign of inadequate circulation that should be identified during the initial assessment?
- A. Warm, pink skin with brisk capillary refill
- B. Delayed capillary refill greater than 2 seconds ✓
- C. Regular pulse of 70 beats per minute
- D. Clear and equal breath sounds bilaterally
Why: Capillary refill time greater than 2 seconds, along with cool or mottled skin, tachycardia, and hypotension, suggests poor perfusion. The other options describe normal findings.
Module 2
Module 2: Airway Management and Breathing Support
Airway Management and Breathing Support
Knowledge check
Q1. Which of the following is the first step in the basic airway management sequence for an unresponsive patient?
- A. Insert an oropharyngeal airway
- B. Open the airway using the head-tilt, chin-lift or jaw-thrust maneuver ✓
- C. Administer high-flow oxygen via non-rebreather mask
- D. Perform endotracheal intubation
Why: The primary step is to open and maintain a patent airway using head-tilt/chin-lift or jaw-thrust (jaw-thrust preferred if cervical spine injury is suspected). Adjuncts and advanced airway devices come only after the airway is opened.
Q2. What is the recommended initial approach for suspected cervical spine injury when opening the airway?
- A. Head-tilt, chin-lift maneuver
- B. Jaw-thrust maneuver without neck extension ✓
- C. Full neck hyperextension
- D. Rolling the patient onto their side without support
Why: The jaw-thrust maneuver opens the airway while keeping the cervical spine in neutral alignment, minimizing the risk of worsening a potential spinal injury. Head-tilt involves neck extension, which should be avoided when spinal injury is suspected.
Q3. Which adjunct airway device is appropriate for an unconscious patient who has no gag reflex?
- A. Nasopharyngeal airway
- B. Oropharyngeal airway ✓
- C. Laryngeal mask airway is never appropriate
- D. Nasogastric tube
Why: An oropharyngeal airway (OPA) is used in unconscious patients without a gag reflex because it can trigger gagging and vomiting in conscious patients. The nasopharyngeal airway is better tolerated by patients with some preserved reflexes.
Q4. What is the typical oxygen flow rate for a non-rebreather mask to deliver the highest inspired oxygen concentration?
- A. 1-2 L/min
- B. 3-4 L/min
- C. 10-15 L/min ✓
- D. 20-25 L/min
Why: A non-rebreather mask requires high flow rates, typically 10-15 L/min, to keep the reservoir bag inflated and deliver FiO2 of roughly 60-90%. Low flows would not prevent room air from diluting the inspired gas.
Q5. Which sign most strongly suggests an inadequate breathing pattern requiring immediate ventilatory support?
- A. Respiratory rate of 16 breaths per minute with normal depth
- B. Cyanosis with altered mental status and shallow, irregular respirations ✓
- C. Mild use of accessory muscles during speech
- D. Occasional coughing with clear breath sounds
Why: Cyanosis combined with altered mental status and shallow, irregular breathing indicates hypoxia and hypoventilation, requiring immediate airway and ventilatory support such as bag-valve-mask ventilation. The other options describe normal or minor findings.
Module 3
Module 3: Circulation and Shock Recognition
Circulation and Shock Recognition
Knowledge check
Q1. Which of the following is the earliest clinical sign of shock in an otherwise healthy adult?
- A. Hypotension with systolic blood pressure below 90 mmHg
- B. Tachycardia with a narrowing pulse pressure ✓
- C. Decreased urine output below 0.5 mL/kg/hr
- D. Altered mental status and confusion
Why: Compensatory tachycardia and a narrowing pulse pressure typically appear before hypotension. Healthy adults can maintain blood pressure through vasoconstriction and increased heart rate, so hypotension is a late sign of shock.
Q2. A patient presents with capillary refill time of 5 seconds, cool extremities, and a heart rate of 120 bpm. Which type of shock is most likely considered first if the patient also has crackles and an elevated jugular venous pressure?
- A. Hypovolemic shock
- B. Distributive shock
- C. Cardiogenic shock ✓
- D. Obstructive shock
Why: Crackles and elevated JVP suggest fluid backing up from a failing heart, pointing to cardiogenic shock. Cool, poorly perfused extremities with prolonged capillary refill reflect low cardiac output. Distributive shock typically causes warm extremities.
Q3. Which vital sign pattern is most consistent with hypovolemic shock from acute hemorrhage?
- A. Bradycardia with hypertension
- B. Tachycardia with hypotension and cool, pale skin ✓
- C. Fever with bounding pulses and warm skin
- D. Normal heart rate with elevated blood pressure
Why: Acute blood loss reduces circulating volume, triggering sympathetic compensation with tachycardia and vasoconstriction (cool, pale skin). Hypotension follows as compensation fails. Bradycardia and hypertension are not expected in hemorrhagic shock.
Q4. What is the shock index, and what value suggests significant hemodynamic compromise?
- A. Systolic BP divided by heart rate; a value below 0.5 suggests compromise
- B. Heart rate divided by systolic BP; a value above 1.0 suggests significant compromise ✓
- C. Mean arterial pressure minus heart rate; a value above 80 suggests compromise
- D. Pulse pressure divided by heart rate; a value above 2.0 suggests compromise
Why: The shock index is heart rate divided by systolic blood pressure. Normal is roughly 0.5 to 0.7, and values above 1.0 are associated with significant hemodynamic compromise and higher risk of requiring intervention.
Q5. A patient with sepsis has warm, flushed skin, bounding pulses, and a low blood pressure. Which type of shock does this presentation most suggest?
- A. Cardiogenic shock
- B. Hypovolemic shock
- C. Distributive shock ✓
- D. Obstructive shock
Why: Sepsis causes widespread vasodilation, producing distributive shock. This leads to warm, flushed skin and bounding pulses due to a wide pulse pressure, despite low blood pressure. Cardiogenic and hypovolemic shock typically present with cool, pale extremities.
Module 4
Module 4: Trauma Care Essentials
Trauma Care Essentials
Knowledge check
Q1. In the primary survey of a trauma patient, which element is assessed first?
- A. Disability (neurologic status)
- B. Airway with cervical spine protection ✓
- C. Breathing and ventilation
- D. Circulation and hemorrhage control
Why: The primary survey follows the ABCDE sequence, beginning with Airway while maintaining cervical spine protection, because an obstructed airway is an immediate threat to life that must be addressed before anything else.
Q2. Which of the following is the most appropriate initial fluid for a hypotensive adult trauma patient with suspected hemorrhagic shock?
- A. Large-volume 0.9% normal saline infusion
- B. Oral rehydration solution
- C. Blood products, such as packed red blood cells, guided by hemorrhage control protocols ✓
- D. Dextrose 5% in water
Why: Hemorrhagic shock requires oxygen-carrying capacity and volume replacement; current guidance favors early blood product transfusion over large crystalloid volumes, which can worsen coagulopathy and dilute clotting factors.
Q3. What does the acronym GCS stand for in trauma assessment?
- A. General Circulatory Status
- B. Glasgow Coma Scale ✓
- C. Global Cardiac Score
- D. Guided Clinical Sedation
Why: The Glasgow Coma Scale assesses eye opening, verbal response, and motor response, with a total score from 3 to 15, and is a standard tool for evaluating neurologic status after trauma.
Q4. A patient with a penetrating chest wound develops absent breath sounds on one side, tracheal deviation away from the injured side, and distended neck veins. What is the most likely diagnosis?
- A. Simple pneumothorax
- B. Tension pneumothorax ✓
- C. Pulmonary contusion
- D. Flail chest
Why: Tracheal deviation away from the injured side, absent breath sounds, and distended neck veins together indicate a tension pneumothorax, which requires immediate needle or finger decompression before imaging.
Q5. Which of the following best describes the purpose of a tourniquet in trauma care?
- A. To reduce pain by blocking nerve conduction
- B. To control life-threatening extremity hemorrhage by occluding arterial and venous flow ✓
- C. To immobilize a suspected fracture
- D. To increase venous access for fluid resuscitation
Why: A tourniquet is applied proximal to a bleeding wound on an extremity to stop life-threatening hemorrhage, and it is one of the most effective interventions for controlling severe limb bleeding in the prehospital and emergency setting.
Module 5
Module 5: Cardiac and Respiratory Emergencies
Cardiac and Respiratory Emergencies
Knowledge check
Q1. A 58-year-old man presents with crushing substernal chest pain radiating to the left arm for 30 minutes. Which initial test should be performed first to identify a possible STEMI?
- A. Serum troponin level
- B. 12-lead electrocardiogram ✓
- C. Chest X-ray
- D. D-dimer
Why: A 12-lead ECG should be obtained within 10 minutes of arrival for any patient with suspected acute coronary syndrome. It identifies ST-segment elevation that would indicate a STEMI requiring immediate reperfusion, and it does not wait for laboratory results.
Q2. Which rhythm is treated with immediate defibrillation in an adult cardiac arrest patient?
- A. Asystole
- B. Pulseless electrical activity
- C. Ventricular fibrillation ✓
- D. Sinus bradycardia with a pulse
Why: Ventricular fibrillation and pulseless ventricular tachycardia are shockable rhythms. Early defibrillation is the most effective intervention. Asystole and PEA are non-shockable and are managed with CPR, epinephrine, and a search for reversible causes.
Q3. A patient with severe asthma exacerbation has a SpO2 of 88% on room air, is using accessory muscles, and can speak only in short phrases. What is the most appropriate initial treatment?
- A. Oral prednisone alone and observation
- B. Supplemental oxygen, nebulized short-acting beta-agonist, and systemic corticosteroids ✓
- C. Immediate intubation without any bronchodilator
- D. Oral antihistamine and discharge
Why: Initial management of acute severe asthma includes supplemental oxygen to target SpO2 of about 93-95%, repeated nebulized salbutamol (with ipratropium often added), and early systemic corticosteroids. Intubation is reserved for patients who fail to respond or show signs of exhaustion.
Q4. In the ABCDE approach to a trauma or medical emergency, what does the letter 'A' stand for?
- A. Assessment of disability
- B. Airway with cervical spine protection ✓
- C. Access to IV therapy
- D. Auscultation of heart sounds
Why: A stands for Airway, with attention to maintaining patency and protecting the cervical spine in patients with possible spinal injury. B is Breathing, C is Circulation, D is Disability (neurological status), and E is Exposure with environmental control.
Q5. Which medication is the first-line drug for a patient in anaphylaxis with airway involvement and hypotension?
- A. Intravenous diphenhydramine
- B. Intramuscular epinephrine ✓
- C. Oral prednisone
- D. Intravenous furosemide
Why: Intramuscular epinephrine (typically 0.5 mg of 1:1000 in the anterolateral thigh for adults) is the first-line treatment for anaphylaxis. Antihistamines and corticosteroids are adjuncts and do not reverse airway obstruction or hypotension as rapidly.
Module 6
Module 6: Neurological Emergencies
Neurological Emergencies
Knowledge check
Q1. Which of the following is the most common initial sign of a stroke that should prompt immediate emergency evaluation?
- A. Sudden onset of facial droop, arm weakness, or speech difficulty ✓
- B. Gradual headache lasting several days
- C. Mild dizziness after standing up quickly
- D. Blurred vision that resolves after rest
Why: Sudden facial droop, unilateral arm weakness, and speech disturbance are classic focal neurological deficits of stroke. Recognizing them early (e.g., with the BE-FAST mnemonic) allows timely thrombolysis or thrombectomy decisions, which are time-sensitive.
Q2. A patient presents with a sudden 'worst headache of my life' that peaked within one minute. What is the most important diagnosis to consider first?
- A. Migraine without aura
- B. Tension-type headache
- C. Subarachnoid hemorrhage ✓
- D. Sinusitis
Why: A thunderclap headache reaching maximal intensity within a minute is a red flag for subarachnoid hemorrhage, often from a ruptured aneurysm. It requires urgent non-contrast CT head and, if negative, consideration of lumbar puncture or CT angiography.
Q3. Which initial measure is most important for a patient with a suspected traumatic brain injury and a decreasing level of consciousness?
- A. Immediate administration of sedatives
- B. Ensuring a patent airway and adequate oxygenation and ventilation ✓
- C. Placing the patient in a fully supine position with no head elevation
- D. Delaying assessment until the patient is more stable
Why: Airway, breathing, and circulation take priority. Hypoxia and hypotension worsen secondary brain injury, so securing the airway and maintaining oxygenation and perfusion are the foundation of initial management. Head elevation to about 30 degrees is also generally recommended.
Q4. What is the typical first-line treatment for an active generalized tonic-clonic seizure lasting more than 5 minutes?
- A. Oral phenytoin
- B. Intravenous or intramuscular benzodiazepine such as lorazepam ✓
- C. Oral carbamazepine
- D. Intravenous insulin
Why: Status epilepticus is defined as seizure activity lasting five or more minutes. Benzodiazepines such as lorazepam are the recommended first-line agents, given promptly via IV or IM route, followed by second-line antiseizure medications if seizures persist.
Q5. Which finding in a patient with suspected meningitis is most suggestive of raised intracranial pressure and warrants caution before lumbar puncture?
- A. Fever above 38 degrees Celsius
- B. Neck stiffness
- C. Papilledema or focal neurological deficits ✓
- D. Nausea without vomiting
Why: Papilledema, focal neurological deficits, altered consciousness, or seizures suggest a space-occupying lesion or raised intracranial pressure. In these cases, imaging such as CT head should be performed before lumbar puncture to reduce the risk of herniation. Fever and neck stiffness are typical meningitis features and do not by themselves contraindicate LP.
Module 7
Module 7: Medical Emergencies and Toxicology
Medical Emergencies and Toxicology
Knowledge check
Q1. Which of the following is the first-line antidote for acetaminophen (paracetamol) overdose?
- A. Flumazenil
- B. N-acetylcysteine ✓
- C. Naloxone
- D. Atropine
Why: N-acetylcysteine replenishes glutathione stores and binds the toxic metabolite NAPQI, preventing hepatocellular injury. It is most effective when started within 8 hours of ingestion, though it is still beneficial later.
Q2. A patient presents with miosis, respiratory depression, and decreased level of consciousness after suspected heroin use. Which antidote should be administered first?
- A. Flumazenil
- B. Physostigmine
- C. Naloxone ✓
- D. Glucagon
Why: Naloxone is a competitive opioid receptor antagonist and is the specific antidote for opioid toxicity. The classic triad of miosis, respiratory depression, and coma points to opioid poisoning. Flumazenil reverses benzodiazepines, not opioids.
Q3. Which of the following is the most appropriate initial step in the management of a patient with suspected cardiac arrest?
- A. Establish an IV line and give epinephrine before starting compressions
- B. Begin high-quality chest compressions and check for a pulse ✓
- C. Obtain a 12-lead ECG before any intervention
- D. Administer amiodarone immediately
Why: In adult cardiac arrest, the priority is immediate high-quality chest compressions and early defibrillation when indicated. Pulse checks should be brief, and drugs and ECG should not delay compressions.
Q4. A child is brought in with a suspected salicylate (aspirin) overdose. Which acid-base disturbance is classically seen early in salicylate toxicity?
- A. Respiratory acidosis
- B. Metabolic alkalosis
- C. Mixed respiratory alkalosis and metabolic acidosis ✓
- D. Pure metabolic acidosis with hypokalemia only
Why: Salicylates directly stimulate the medullary respiratory center, causing hyperventilation and respiratory alkalosis. Uncoupling of oxidative phosphorylation produces a metabolic acidosis, so the early picture is often mixed.
Q5. Which finding is most suggestive of organophosphate poisoning?
- A. Dilated pupils and tachycardia
- B. Bradycardia, salivation, lacrimation, urination, and diarrhea ✓
- C. Warm, dry skin with hyperthermia
- D. Hypotension with flushed skin
Why: Organophosphates inhibit acetylcholinesterase, causing muscarinic excess, which produces the mnemonic SLUDGE/DUMBELS features: salivation, lacrimation, urination, defecation, GI upset, emesis, and bradycardia with bronchorrhea. Atropine is the key treatment.
