Question 1: What is the primary responsibility of an EMT-Basic at the scene of a
medical emergency?
A. To diagnose the patient's underlying disease process
B. To provide definitive care and cure the patient
C. To assess the patient and manage life-threatening emergencies
D. To transport the patient to the hospital as quickly as possible regardless of condition
CORRECT ANSWER: C. To assess the patient and manage life-threatening
emergencies
Rationale: The primary role of an EMT-Basic is to perform a patient assessment,
manage immediate life threats (such as airway obstruction, severe bleeding, or cardiac
arrest), and prepare the patient for transport. Diagnosis and definitive cure are roles of
physicians, and speed should never compromise patient safety or necessary on-scene
interventions.
Question 2: Which of the following is considered a standard precaution that must
be taken by all EMS providers during every patient contact?
A. Wearing a N95 respirator
B. Wearing gloves
C. Wearing a face shield
D. Wearing a gown
CORRECT ANSWER: B. Wearing gloves
Rationale: Gloves are the minimum standard precaution required for all patient
contacts to prevent exposure to blood and body fluids. Other PPE such as masks, face
shields, or gowns are used based on specific situational risks (e.g., splashing, airborne
diseases), but gloves are universal.
Question 3: In the context of legal consent, what does "implied consent" apply to?
A. A conscious adult who refuses treatment
B. A minor whose parents are present and consenting
C. An unconscious patient who cannot give verbal consent
D. A patient who is mentally altered but awake
CORRECT ANSWER: C. An unconscious patient who cannot give verbal consent
Rationale: Implied consent assumes that a reasonable person would want life-saving
care if they were able to communicate. It applies primarily to patients who are
,unconscious, mentally altered to the point of incapacity, or minors without a guardian
present, where delay in care would cause harm.
Question 4: Which anatomical plane divides the body into left and right halves?
A. Transverse plane
B. Coronal plane
C. Sagittal plane
D. Frontal plane
CORRECT ANSWER: C. Sagittal plane
Rationale: The sagittal plane runs vertically from front to back, dividing the body into
left and right sections. The transverse plane divides the body into top and bottom, while
the coronal (or frontal) plane divides it into front and back.
Question 5: What is the normal respiratory rate for an adult?
A. 8–10 breaths per minute
B. 12–20 breaths per minute
C. 20–30 breaths per minute
D. 30–40 breaths per minute
CORRECT ANSWER: B. 12–20 breaths per minute
Rationale: The normal resting respiratory rate for an adult is typically between 12 and
20 breaths per minute. Rates below 12 indicate bradypnea, and rates above 20 indicate
tachypnea, both of which may signal underlying pathology.
Question 6: Which bone is located in the upper arm?
A. Radius
B. Ulna
C. Humerus
D. Femur
CORRECT ANSWER: C. Humerus
Rationale: The humerus is the long bone of the upper arm, extending from the shoulder
to the elbow. The radius and ulna are forearm bones, and the femur is the thigh bone.
Question 7: When moving a patient with a suspected spinal injury, which device is
most appropriate for immobilization?
A. Wheeled stretcher
B. Long backboard
C. Scoop stretcher
D. Portable chair
CORRECT ANSWER: B. Long backboard
,Rationale: A long backboard provides rigid support for the entire spine, minimizing
movement during extrication and transport. While scoop stretchers can be used for
lifting, the long backboard remains the standard for full spinal immobilization in trauma
scenarios.
Question 8: What is the first step in the patient assessment sequence?
A. Primary assessment
B. History taking
C. Scene size-up
D. Secondary assessment
CORRECT ANSWER: C. Scene size-up
Rationale: Before approaching the patient, the EMT must ensure scene safety,
determine the mechanism of injury or nature of illness, and identify the number of
patients. This protects the provider and guides subsequent actions.
Question 9: Which pulse site is preferred for assessing circulation in an
unconscious adult?
A. Radial
B. Carotid
C. Brachial
D. Pedal
CORRECT ANSWER: B. Carotid
Rationale: The carotid pulse is central and usually remains palpable longer than
peripheral pulses (like radial) in states of shock or low blood pressure. It is the standard
site for checking circulation in unconscious adults.
Question 10: What is the correct compression-to-ventilation ratio for single-
rescuer CPR in an adult?
A. 15:2
B. 30:2
C. 5:1
D. 15:1
CORRECT ANSWER: B. 30:2
Rationale: Current AHA guidelines recommend a 30:2 ratio for single-rescuer adult CPR
to maximize coronary perfusion pressure while providing adequate oxygenation.
Question 11: Which of the following is a sign of hypoxia?
A. Pink skin color
B. Bradycardia
C. Cyanosis
D. Hypertension
, CORRECT ANSWER: C. Cyanosis
Rationale: Cyanosis, a bluish discoloration of the skin or mucous membranes,
indicates low oxygen levels in the blood. Tachycardia (not bradycardia) and agitation are
also common early signs, while pink skin indicates adequate oxygenation.
Question 12: What is the proper technique for opening the airway in a patient with
no suspected spinal injury?
A. Jaw-thrust maneuver
B. Head-tilt/chin-lift maneuver
C. Neck extension
D. Hyperextension of the neck
CORRECT ANSWER: B. Head-tilt/chin-lift maneuver
Rationale: The head-tilt/chin-lift is the standard method for opening the airway in
medical patients or trauma patients without suspected spinal injury. The jaw-thrust is
reserved for patients with suspected spinal injuries.
Question 13: Which oxygen delivery device delivers the highest concentration of
oxygen?
A. Nasal cannula
B. Simple face mask
C. Non-rebreather mask
D. Venturi mask
CORRECT ANSWER: C. Non-rebreather mask
Rationale: A non-rebreather mask with a reservoir bag and one-way valves can deliver
up to 90–95% oxygen when flowed at 15 L/min. Nasal cannulas deliver 24–44%, and
simple masks deliver 35–50%.
Question 14: What is the primary indication for using an automated external
defibrillator (AED)?
A. Asystole
B. Pulseless electrical activity (PEA)
C. Ventricular fibrillation
D. Severe bradycardia
CORRECT ANSWER: C. Ventricular fibrillation
Rationale: AEDs are designed to detect and treat shockable rhythms, specifically
ventricular fibrillation (VF) and pulseless ventricular tachycardia (VT). They do not shock
asystole or PEA.
Question 15: Which of the following conditions is characterized by a sudden onset
of shortness of breath and wheezing?
