GRADED A+
Question 1
Which of the following is the primary responsibility of an Emergency Medical
Technician (EMT)?
A) Providing definitive medical care at the scene.
B) Safely transporting patients to the hospital.
C) Assessing a patient and providing appropriate emergency medical care.
D) Documenting all medical procedures performed by the physician.
E) Performing advanced life support interventions.
Correct Answer: C) Assessing a patient and providing appropriate
emergency medical care.
Rationale: The primary role of an EMT is to assess a patient's
condition, provide immediate basic life support (BLS) care, and
prepare them for transport to a medical facility.
Question 2
During a mass casualty incident, which of the following is the highest priority
for an EMT's personal safety?
A) Immediately treating all visible injuries.
B) Establishing a clear communication channel.
C) Scene size-up and ensuring scene safety.
D) Documenting the patient's medical history.
E) Directing traffic away from the scene.
Correct Answer: C) Scene size-up and ensuring scene safety.
Rationale: An EMT's personal safety is paramount. Before any patient
contact, a thorough scene size-up to identify and mitigate hazards
(e.g., traffic, violence, hazardous materials) is the highest priority,
adhering to the principle "Don't become a patient."
Question 3
Which of the following is considered a component of the "Chain of Survival"
for a cardiac arrest patient?
A) Early definitive care.
B) Immediate advanced life support (ALS).
C) Rapid defibrillation.
D) Delayed activation of EMS.
E) Transport before CPR.
Correct Answer: C) Rapid defibrillation.
Rationale: The Chain of Survival includes early recognition and
activation of EMS, early CPR, rapid defibrillation, effective advanced
,life support, and integrated post-cardiac arrest care. Rapid
defibrillation is a critical link.
Question 4
An EMT is assessing an unresponsive patient. To open the airway of a patient
without suspected spinal trauma, which maneuver should the EMT use?
A) Jaw-thrust maneuver.
B) Head-tilt, chin-lift maneuver.
C) Recovery position.
D) Nasopharyngeal airway insertion.
E) Oropharyngeal airway insertion.
Correct Answer: B) Head-tilt, chin-lift maneuver.
Rationale: The head-tilt, chin-lift maneuver is the standard method
for opening the airway in an unresponsive patient who does not
have a suspected spinal injury. It moves the tongue away from the
posterior pharynx.
Question 5
What is the normal respiratory rate for a healthy adult at rest?
A) 8-10 breaths per minute.
B) 10-12 breaths per minute.
C) 12-20 breaths per minute.
D) 20-24 breaths per minute.
E) 24-30 breaths per minute.
Correct Answer: C) 12-20 breaths per minute.
Rationale: The normal respiratory rate for a resting adult is typically
considered to be between 12 and 20 breaths per minute.
Question 6
Which of the following would be an appropriate indicator to administer
oxygen to a patient?
A) SpO2 of 98% on room air.
B) Respiratory rate of 16 breaths per minute.
C) Signs of hypoxia, such as cyanosis or altered mental status.
D) Patient states they feel "fine."
E) Blood pressure of 120/80 mmHg.
Correct Answer: C) Signs of hypoxia, such as cyanosis or altered
mental status.
Rationale: Oxygen is administered to patients showing signs of
inadequate oxygenation (hypoxia), which can manifest as cyanosis
,(bluish discoloration), altered mental status, or significant
respiratory distress, even if pulse oximetry is not yet severely low.
Question 7
The most common cause of airway obstruction in an unresponsive adult
patient is:
A) Foreign body.
B) Tongue.
C) Vomit.
D) Blood.
E) Swelling from allergic reaction.
Correct Answer: B) Tongue.
Rationale: In an unresponsive patient, the relaxed tongue is the most
common cause of airway obstruction, falling back against the
posterior pharynx.
Question 8
When performing the jaw-thrust maneuver, the EMT should:
A) Tilt the patient's head back forcefully.
B) Push the chin upward to lift the jaw.
C) Place fingers behind the angles of the jaw and lift the jaw forward.
D) Apply pressure directly to the patient's teeth.
E) Use a tongue depressor to move the tongue forward.
Correct Answer: C) Place fingers behind the angles of the jaw and lift
the jaw forward.
Rationale: The jaw-thrust maneuver is used when spinal injury is
suspected. It involves placing fingers behind the angles of the
patient's lower jaw and gently lifting the jaw forward without tilting
the head.
Question 9
An EMT is caring for a patient who is actively vomiting. To prevent aspiration,
the EMT should:
A) Perform the head-tilt, chin-lift.
B) Place the patient in the recovery position (on their side).
C) Insert an oropharyngeal airway.
D) Administer high-flow oxygen.
E) Give antiemetic medication.
Correct Answer: B) Place the patient in the recovery position (on their
side).
Rationale: Placing an unconscious or vomiting patient in the recovery
, position (lateral recumbent) allows gravity to assist with drainage
of fluids from the mouth, minimizing the risk of aspiration into the
lungs.
Question 10
Which of the following is a normal pulse rate for an adult at rest?
A) 40-50 beats per minute.
B) 50-60 beats per minute.
C) 60-100 beats per minute.
D) 100-120 beats per minute.
E) 120-140 beats per minute.
Correct Answer: C) 60-100 beats per minute.
Rationale: A normal resting pulse rate for a healthy adult is generally
considered to be between 60 and 100 beats per minute.
Question 11
What does "implied consent" mean in the context of emergency medical
care?
A) The patient verbally agrees to treatment.
B) The patient signs a consent form.
C) Consent is assumed for an unconscious, incapacitated, or severely injured
patient in need of life-saving treatment.
D) Consent is given by a family member.
E) The patient refuses treatment.
Correct Answer: C) Consent is assumed for an unconscious,
incapacitated, or severely injured patient in need of life-saving
treatment.
Rationale: Implied consent is a legal principle that assumes a
reasonable person would want life-saving treatment if they were
unable to provide express consent. It applies to unresponsive or
severely incapacitated individuals.
Question 12
Which of the following personal protective equipment (PPE) should an
EMT always wear when anticipating contact with blood or body fluids?
A) N95 respirator.
B) Eye protection.
C) Sterile gloves.
D) Gloves.
E) Face shield.
Correct Answer: D) Gloves.
