How is shock (hypoperfusion) defined in the chapter on Emergency Care and Transportation of the Sick and Injured?
As a psychological condition requiring immediate attention
As inadequate cellular perfusion
As an overabundance of cellular perfusion
As a type of allergic reaction
What can a compromise in perfusion lead to?
Cellular injury or death
Improved cellular function
Increased cellular oxygen
Decreased cellular waste
What is diffusion as described in the context of respiratory physiology?
The active transport of molecules from an area of lower concentration to an area of higher concentration.
The movement of molecules from an area of higher concentration to an area of lower concentration without the use of energy.
The process by which oxygen is used up by the cells and carbon dioxide is produced.
The exchange of gases between the blood and the external environment.
Which of the following is NOT a way that carbon dioxide is transported in the blood?
Dissolved in the plasma.
Combined with water in the form of bicarbonate.
Attached to hemoglobin.
Bound to oxygen molecules.
What is the "perfusion triangle" in the cardiovascular system?
The heart, lungs, and brain.
The heart, blood vessels, and blood.
The heart, liver, and kidneys.
The heart, spleen, and pancreas.
What does systolic pressure represent?
The pressure in the arteries when the heart is at rest.
The pressure in the veins during heartbeats.
The peak arterial pressure when the heart contracts.
The difference between the pressure during heartbeats and between heartbeats.
What is pulse pressure?
The pressure in the arteries when the heart is at rest.
The peak arterial pressure when the heart contracts.
The pressure maintained within the arteries while the heart rests between heartbeats.
The difference between the systolic and diastolic pressures.
What might a pulse pressure of less than 25 mm Hg indicate?
The patient is experiencing a hypertensive crisis.
The patient is likely in a state of shock.
The patient has a healthy cardiovascular system.
The patient is undergoing a stress test.
What regulates blood flow through the capillary beds?
The autonomic nervous system
The capillary sphincters
The sympathetic nervous system
Hormones such as epinephrine and norepinephrine
What is the result of the buildup of pulmonary fluid in cardiogenic shock?
Pulmonary edema
Vasodilation
Increased oxygen exchange
Decreased heart rate
Which system takes more control of the body's functions during a fight-or-flight response?
Parasympathetic nervous system
Sympathetic nervous system
Central nervous system
Endocrine system
What is cardiogenic shock a result of?
A mechanical obstruction in the heart chambers
The heart's inability to maintain sufficient output to meet the demands of the body
Widespread dilation of small arterioles, small venules, or capillaries
A severe allergic reaction
Which of the following is NOT a factor upon which cardiac output depends?
The heart's preload
The heart's afterload
The heart's myocardial contractility
The heart's position in the body
Obstructive shock can be caused by all of the following EXCEPT:
Cardiac tamponade
Tension pneumothorax
Pulmonary embolism
High spinal cord injury
What is a common result of septic shock?
Cardiac tamponade
Tension pneumothorax
Widespread dilation of vessels and plasma loss through injured vessel walls
Anaphylactic reaction
Neurogenic shock is usually the result of:
A mechanical obstruction
A severe infection
High spinal cord injury
An allergic reaction
What is hypovolemic shock a result of?
A sudden reaction of the nervous system
An inadequate amount of fluid or volume in the circulatory system
Severe allergic reaction
A major heart attack
Which of the following is true about the progression of shock?
Blood pressure is the first measurable factor to change in shock
A drop in blood pressure indicates that shock is in the early stages
Blood pressure may be the last measurable factor to change in shock
Infants and children can't maintain their blood pressure until they have lost almost all their blood volume
What is the first step in managing a patient with massive hemorrhage according to the text?
Provide high-flow oxygen
Assess the airway to ensure it is patent
Apply a tourniquet or direct pressure dressings
Request advanced life support
What scale is used to assess the patient's level of consciousness in the primary assessment?
SAMPLE scale
AVPU scale
ABC scale
CPR scale
What should be done if the patient has no pulse and is not breathing?
Provide high-flow oxygen
Begin cardiopulmonary resuscitation (CPR)
Check for a central pulse
Request advanced life support
What is required to relieve the pressure in the chest for a patient with tension pneumothorax?
High-flow oxygen
Antibiotics
Chest decompression
Immediate surgery
What is the most effective treatment for a severe, acute allergic reaction according to the text?
Administering high-flow oxygen
Providing spinal immobilization
Administering epinephrine by way of intramuscular injection
Assisting ventilations with a bag-mask device if necessary
What is the first step in treating hypovolemic shock as mentioned in the text?
Providing spinal immobilization
Assisting inadequate breathing as needed
Controlling all obvious external bleeding
Ensuring the most effective circulation possible
Which of the following is NOT a sign of shock?
Rapid pulse
Warm, dry skin
Shallow breathing
Pale or clammy skin
