Question 1
What is the primary function of the respiratory system?
A) Digestion of food
B) Gas exchange (oxygen and carbon dioxide)
C) Blood circulation
D) Nerve signal transmission
Correct Answer: B) Gas exchange (oxygen and carbon dioxide)
Rationale:
, The respiratory system's primary function is gas exchange - bringing oxygen into the body and removing carbon dioxide. This occurs in the alveoli of
the lungs.
Anatomy & Physiology
Question 2
Which chamber of the heart pumps oxygenated blood to the body?
A) Right atrium
B) Right ventricle
C) Left atrium
D) Left ventricle
Correct Answer: D) Left ventricle
Rationale:
The left ventricle pumps oxygenated blood through the aorta to the entire body. It has the thickest wall due to the high pressure needed for systemic
circulation.
Anatomy & Physiology
Question 3
What is the normal adult resting heart rate range?
A) 40-60 beats/min
B) 60-100 beats/min
C) 100-120 beats/min
D) 120-140 beats/min
Correct Answer: B) 60-100 beats/min
Rationale:
Normal adult resting heart rate is 60-100 beats per minute. Rates below 60 indicate bradycardia; above 100 indicate tachycardia. Athletes may have
lower resting rates.
Patient Assessment
, Question 4
In TCCC, what does 'MARCH' stand for?
A) Massive hemorrhage, Airway, Respiration, Circulation, Hypothermia/Head injury
B) Medical, Airway, Respiratory, Cardiac, Head
C) Major, Assessment, Rescue, Care, Help
D) None of the above
Correct Answer: A) Massive hemorrhage, Airway, Respiration, Circulation, Hypothermia/Head
injury
Rationale:
MARCH is the TCCC assessment algorithm: Massive hemorrhage, Airway, Respiration, Circulation, Hypothermia/Head injury. This prioritizes life-
threatening conditions in tactical environments.
TCCC
Question 5
What is the FIRST priority in any emergency situation?
A) Patient care
B) Scene safety
C) Documentation
D) Calling for help
Correct Answer: B) Scene safety
Rationale:
Scene safety is always the first priority. You cannot help patients if you become a casualty yourself. Ensure the scene is safe before approaching any
patient.
Emergency Care Fundamentals
Question 6
Which artery is used to check pulse in an unconscious adult?
A) Radial
, B) Brachial
C) Carotid
D) Pedal
Correct Answer: C) Carotid
Rationale:
Carotid artery is used for unconscious adults as it's the most central and accessible pulse during low perfusion states. Radial is for conscious patients;
brachial for infants.
Patient Assessment
Question 7
What is the normal adult respiratory rate?
A) 8-12 breaths/min
B) 12-20 breaths/min
C) 20-30 breaths/min
D) 30-40 breaths/min
Correct Answer: B) 12-20 breaths/min
Rationale:
Normal adult respiratory rate is 12-20 breaths per minute. Below 12 is bradypnea; above 20 is tachypnea. Rates should be regular and unlabored.
Patient Assessment
Question 8
Which type of bleeding is MOST life-threatening?
A) Capillary
B) Venous
C) Arterial
D) All are equal
Correct Answer: C) Arterial
