1. A 45-year-old male is unresponsive with no pulse and not breathing. After calling for help, what
is the EMT’s first action?
A) Apply oxygen
B) Begin high-quality chest compressions
C) Insert an oropharyngeal airway
D) Obtain a medical history
Answer B: Begin high-quality chest compressions
Rationale: High-quality CPR (compressions first) is the priority in cardiac arrest until defibrillator arrives.
2. A patient with a history of asthma is having difficulty breathing and has a peak flow reading of
40% of personal best. Which medication should the EMT assist with?
A) Oral prednisone
B) Albuterol (via inhaler or nebulizer)
C) Ipratropium alone
D) Oxygen only
Answer B: Albuterol (via inhaler or nebulizer)
Rationale: Albuterol is a bronchodilator used for acute asthma exacerbation; administer as prescribed or
per protocol.
3. Which of the following is a sign of a tension pneumothorax?
A) Absent breath sounds on the affected side
B) Tracheal deviation away from the affected side
C) Subcutaneous emphysema
,D) Jugular vein distension (JVD)
Answer B: Tracheal deviation away from the affected side
Rationale: Tension pneumothorax causes tracheal deviation away from the affected side due to
mediastinal shift.
4. A 35-year-old female is found unresponsive with a syringe nearby. She is breathing shallowly
and has pinpoint pupils. Which medication should the EMT anticipate?
A) Flumazenil
B) Naloxone (Narcan)
C) Epinephrine
D) Dextrose 50%
Answer B: Naloxone (Narcan)
Rationale: Pinpoint pupils and respiratory depression with a syringe suggest opioid overdose; naloxone
is the antidote.
5. A patient with chest pain and difficulty breathing has a pulse of 120, blood pressure 100/70, and
an SpO2 of 88%. Which action should the EMT take first?
A) Apply oxygen at 2 L/min
B) Apply oxygen at 10 L/min via non-rebreather
C) Administer aspirin
D) Obtain a 12-lead ECG
Answer B: Apply oxygen at 10 L/min via non-rebreather
Rationale: Hypoxemia requires high-flow oxygen; then reassess and consider aspirin.
6. A patient is bleeding profusely from a laceration on the forearm. What is the first step in
hemorrhage control?
A) Apply a tourniquet
B) Apply direct pressure
,C) Elevate the arm
D) Apply pressure at a proximal pressure point
Answer B: Apply direct pressure
Rationale: Direct pressure is the first line for bleeding control; tourniquet if direct pressure fails.
7. In a pregnant patient in labor, the first sign of imminent delivery is:
A) Rupture of membranes
B) Crowning of the baby’s head
C) Contractions every 2 minutes
D) Maternal urge to push
Answer B: Crowning of the baby’s head
Rationale: Crowning is the visible appearance of the head, indicating delivery is imminent.
8. A patient is in cardiac arrest and the AED advises “shock.” What should the EMT do next?
A) Continue CPR
B) Clear the patient and press the shock button
C) Check for a pulse
D) Reanalyze the rhythm
Answer B: Clear the patient and press the shock button
Rationale: Ensure no one is touching the patient, then deliver shock as advised.
9. A 2-year-old child with a fever has stridor and a barking cough. Which condition is most likely?
A) Epiglottitis
B) Croup
C) Bronchiolitis
D) Foreign body aspiration
Answer B: Croup
Rationale: Stridor and barking cough are classic for croup (laryngotracheobronchitis).
, 10. What is the proper depth for chest compressions on an adult during CPR?
A) At least 1 inch
B) At least 2 inches (5 cm)
C) At least 3 inches
D) At least 4 inches
Answer B: At least 2 inches (5 cm)
Rationale: AHA guidelines recommend compression depth of at least 2 inches (5 cm) for adults.
11. A 65-year-old male has sudden onset of severe chest pain, diaphoresis, and nausea. Which
medication should the EMT administer (if not contraindicated)?
A) Nitroglycerin
B) Aspirin (324 mg chewed)
C) Morphine
D) Metoprolol
Answer B: Aspirin (324 mg chewed)
Rationale: Aspirin reduces mortality in acute coronary syndrome; give chewed or crushed.
12. A patient with a spinal cord injury at T6 reports a severe headache and has a blood pressure of
210/110. Which condition is most likely?
A) Hypertensive emergency
B) Autonomic dysreflexia
C) Stroke
D) Heat stroke
Answer B: Autonomic dysreflexia
Rationale: Autonomic dysreflexia occurs in spinal cord injuries above T6 and causes severe hypertension.
