Question 1
Which type of shock is caused by inadequate function of the heart, often developing within 24
hours of an acute myocardial infarction (AMI)?
A) Obstructive shock
B) Distributive shock
C) Cardiogenic shock
D) Hypovolemic shock
E) Neurogenic shock
Correct Answer: C) Cardiogenic shock
Rationale: Cardiogenic shock occurs when the heart muscle is unable to maintain sufficient
cardiac output to meet the metabolic demands of the body. It is frequently caused by a
large AMI that impairs the heart's pumping ability. It can manifest immediately or up to 24
hours after the cardiac event.
Question 2
What type of shock results from a mechanical obstruction that prevents the heart from filling or
pumping effectively, such as a cardiac tamponade?
A) Septic shock
B) Obstructive shock
C) Psychogenic shock
D) Anaphylactic shock
E) Hypovolemic shock
Correct Answer: B) Obstructive shock
Rationale: Obstructive shock is caused by physical conditions that impede the flow of blood
into or out of the heart chambers. Common causes include cardiac tamponade, tension
pneumothorax, and pulmonary embolism.
Question 3
Which of the following clinical findings constitutes "Beck's Triad," indicating a cardiac
tamponade?
A) Hypertension, bradycardia, and irregular respirations
B) JVD, narrowing pulse pressure, and muffled heart sounds
C) Hypotension, tachycardia, and clear lung sounds
D) Fever, abdominal pain, and rebounding tenderness
E) Cyanosis, hemoptysis, and tachypnea
Correct Answer: B) JVD, narrowing pulse pressure, and muffled heart sounds
Rationale: Beck’s Triad is the classic set of signs for cardiac tamponade. Jugular Venous
Distention (JVD) occurs because blood cannot enter the right atrium; muffled heart sounds
, 2
occur because of the fluid surrounding the heart; and narrowing pulse pressure occurs as
the heart's stroke volume decreases.
Question 4
Distributive shock is characterized by which of the following physiological changes?
A) Loss of blood volume due to external hemorrhage
B) Mechanical compression of the vena cava
C) Widespread dilation of small arterioles and venules
D) Increased cardiac contractility
E) Rupture of the visceral pleura
Correct Answer: C) Widespread dilation of small arterioles and venules
Rationale: In distributive shock, the total volume of blood is unchanged, but the container
(the vascular bed) becomes too large for the amount of fluid inside. This results in pooling
of blood in the periphery and decreased tissue perfusion.
Question 5
A patient presents with bradycardia, low blood pressure, and warm, dry skin following a spinal
cord injury. Which type of distributive shock is most likely?
A) Septic shock
B) Anaphylactic shock
C) Neurogenic shock
D) Psychogenic shock
E) Hypovolemic shock
Correct Answer: C) Neurogenic shock
Rationale: Neurogenic shock occurs when a spinal cord injury interrupts the sympathetic
nervous system. This leads to massive vasodilation (causing hypotension) and a loss of the
compensatory tachycardia mechanism (resulting in bradycardia). The skin remains warm
because blood is trapped in the dilated peripheral vessels.
Question 6
Hypovolemic shock begins to manifest significantly when a patient loses approximately what
percentage of their total blood volume?
A) 5%
B) 10%
C) 15%
D) 25%
E) 40%
Correct Answer: C) 15%
Rationale: The body can typically compensate for minor blood loss, but once the loss
reaches approximately 15% of total blood volume, the compensatory mechanisms begin to
fail and signs of shock (hypoperfusion) become evident.

Question 7
What are the fundamental steps for treating any patient suspected of being in shock?
A) Administer oral glucose and keep the patient cool
B) Keep the patient warm, control bleeding, position of comfort, and high-flow oxygen
C) Perform chest compressions immediately and apply an AED
D) Elevate the feet 24 inches and provide small sips of water
E) Administer activated charcoal and keep the patient walking
Correct Answer: B) Keep the patient warm, control bleeding, position of comfort, and high-
flow oxygen
Rationale: Standard shock treatment focuses on maintaining perfusion and preventing
further deterioration. Controlling bleeding stops volume loss, oxygen improves tissue
oxygenation, and warmth prevents the coagulopathy associated with hypothermia.
Question 8
In the absence of adequate oxygenation, at what point does permanent brain damage typically
occur?
A) 1 minute
B) 2 minutes
C) 4 minutes
D) 6 minutes
E) 10 minutes
Correct Answer: D) permanent brain damage within 6 minutes
Rationale: Without oxygen, the brain begins to suffer. Cardiac arrest or initial brain
damage starts at 4 minutes; the damage becomes permanent and irreversible by 6 minutes;
and death is highly likely after 10 minutes.
Question 9
You are treating a conscious adult with a severe Foreign Body Airway Obstruction (FBAO) who
cannot cough or speak. What is the correct sequence of actions?
A) Give 30 chest compressions
B) Perform 5 back blows followed by 5 abdominal thrusts
C) Perform 15 back blows only
D) Blindly sweep the mouth with your finger
E) Give 2 rescue breaths immediately
Correct Answer: B) bending patient forward at the waist... 5 back blows... then 5 abdominal
thrusts
Rationale: Current guidelines for a conscious adult with a complete airway obstruction
involve alternating between 5 firm back blows between the shoulder blades and 5
abdominal thrusts (Heimlich maneuver) until the object is expelled or the patient becomes
unconscious.

Question 10
If a patient with an airway obstruction loses consciousness, what should the EMT do next?
A) Check for a carotid pulse for 10 seconds
B) Begin CPR starting with chest compressions
C) Perform 5 more back blows
D) Attempt to ventilate through the nose
E) Wait for ALS to arrive
Correct Answer: B) if patient loses consciousness, give CPR starting with chest compressions
Rationale: Once an FBAO patient becomes unresponsive, the priority shifts to chest
compressions. Compressions provide more internal pressure than thrusts to dislodge the
object. You should look inside the mouth for a visible object before attempting any breaths,
but do not check for a pulse first.
Question 11
When treating an infant with a severe airway obstruction, where should the chest thrusts be
delivered?
A) In the middle of the abdomen
B) Just below the nipples, using 2 to 3 fingers
C) On the upper part of the sternum
D) Using the heel of the hand on the xiphoid process
E) Between the shoulder blades
Correct Answer: B) 5 chest thrusts; place 2 to 3 fingers in the middle of the chest just below
the nipples.
Rationale: For infants, abdominal thrusts are avoided due to potential organ damage.
Instead, the EMT uses 5 back blows and 5 chest thrusts (compressing approximately 1.5
inches) while keeping the infant's head lower than the body.
Question 12
What is the correct ventilation rate for an adult patient when performing mouth-to-mask or
mouth-to-mouth ventilation?
A) 1 breath every 3 seconds
B) 1 breath every 5 to 6 seconds
C) 1 breath every 10 seconds
D) 10 to 12 breaths every minute
E) 2 breaths every 15 seconds
Correct Answer: B) give 1 breath every 5 to 6 seconds for adults
Rationale: For an adult with a pulse but inadequate or absent breathing, rescue breaths
should be delivered at a rate of 10-12 per minute, which equates to one breath every 5 to 6
seconds.
