Choose:
If blood is not circulated adequately through the body’s capillaries, cells become starved for oxygen and nutrients, and overloaded with carbon dioxide and waste products.
This condition is known as:
A. cardiac compromise.
B. hypoperfusion.
C. circulatory depression.
D. hypotension.
B
under some conditions, blood does not circulate adequately through all the body’s capillaries
chief result of inadequate circulation is a state of profound depression of cell perfusion, called shock (or hypoperfusion)
cells become starved for oxygen (hypoxia) and nutrients, and become overloaded with carbon dioxide and other waste products
Answer:
How does the vascular system control temperature regulation?
The body’s mechanism to conserve heat is to expand (dilate) or narrow (constrict) the blood vessels.
dilation of the blood vessels contributes to heat dissipation, whereas constriction of the blood vessels preserves core temperature by decreasing heat dissipation
Choose:
Gas exchange of oxygen for carbon dioxide occurs at the cellular level of the body between:
A. capillaries and veins.
B. capillaries and body cells.
C. arteries and body cells.
D. arteries and capillaries.
B
Choose:
Of the following adjustments to the vascular system, which will contribute the most to increased perfusion to the core?
A. Decreased vascular diameter
B. Increased blood volume
C. Decreased heart rate
D. Increased oxygen consumption
A
laws of hemodynamics demonstrate that a reduction in vascular diameter has the greatest influence on perfusion
conversely, increasing the diameter would cause a reduction in perfusion, as is seen with septic and anaphylactic shock

A. Increased heart rate
B. Vasodilation
C. Decreased respirations
D. Decreased heart rate
A

The body starts to “shunt” the blood from the extremities to the core of the body to protect the main organs of life (lungs, heart, brain, liver, spleen, etc.)
Choose:
Which patient is in the initial stages of shock?
A. 45-year-old motor vehicle crash victim with pale, cool, skin and tachycardia
B. 16-year-old female with a possible traumatic brain injury presenting with altered mental status and low blood pressure
C. 36-year-old fall victim with absent peripheral pulses
D. 52-year-old assault victim with bilaterally dilated pupils and cyanosis
A
initial presentation of shock symptoms include pale/cool/clammy skin, tachycardia, and tachypnea
vital signs will deteriorate, with low blood pressure, thirst, dilated pupils, and cyanosis as shock progresses to late signs
Choose:
Your patient is a 49-year-old female with complaints of shortness of breath and generalized weakness. On examination, you note that she has extensive crackles in her lungs, swelling of her feet and ankles, and difficulty in breathing when lying down. This is troublesome for her because she gets lightheaded when sitting up, because of her low blood pressure.
You would classify her shock as:
A. neurogenic shock.
B. anaphylactic shock.
C. septic shock.
D. cardiogenic shock.
D
the patient’s signs and symptoms suggest congestive heart failure, indicating cardiogenic shock, because the pumping mechanism has been compromised
Choose:
Which of the following would most likely lead to hypovolemic shock?
A. Open fracture of the hand
B. Subdural hematoma
C. Crush injury to the foot
D. Crush injury to the abdomen
D
hypovolemic shock is most often caused by significant blood loss due to trauma or internal hemorrhage from a medical cause (such as an AAA, GI bleed, or crush injuries to major body cavities, such as the chest or abdomen)
hypovolemic shock may also result from third-space losses such as fluid shifts into various body compartments, as in severe pancreatitis, or fluid loss from protracted vomiting
Choose:
Your 55-year-old female patient is suffering from a rupturing abdominal aortic aneurysm, and is entering into the decompensating stage of shock.
What finding would not be an indicator of decompensated shock in this patient?
A. Cyanosis
B. Dilated pupils
C. Increased heart rate
D. Falling blood pressure
C
increased heart rate would be a sign of early, compensating shock (not an indicator of decompensated shock)

You are assessing a 53-year-old male with severe blood loss from a wound that is covered with a pressure bandage. Bleeding appears to have stopped. The patient’s pulse and respiration are elevated, but blood pressure is falling. The patient’s skin around the lips shows signs of cyanosis, and the patient’s pupils are dilated.
What is a sign that the patient has entered decompensated shock?
A. Cyanotic skin
B. Severe blood loss
C. Elevated pulse
D. Elevated respiration
A
cyanosis around the lips and nail beds is one of the signs of late shock (which would indicate the onset of decompensated shock)
B is wrong because severe blood loss alone does not indicate decompensated shock
C and D are wrong because an elevated pulse and respiration would be consistent with compensated shock
Choose:
You are caring for a 28-year-old male patient who was involved in a motor vehicle crash. He has sustained a closed head injury and blunt-force trauma to his chest and abdomen, and is unconscious and in shock.

D
shock position… also consider the MVC and need for immobilization

C. Place the patient on high-flow oxygen via nonrebreather.
D. Transport the patient to the most appropriate facility as soon as possible.
A
(in addition to depleting the body’s energy stores) hypothermia may reduce the body’s ability to clot
keeping the patient warm may prevent heat loss (which contributes to hypothermia)

Finding arterial bleeding quickly is very important in assessing a patient.
Which statement about arterial bleeding is correct?
A. Clot formation takes place rapidly.
B. Arterial bleeding is often rapid and profuse.
C. Arterial bleeding is the least difficult type of bleeding to control.

B. hemostatic gauze into the wound
C. ice packs into the wound
D. a commercial tourniquet
B
the key is to stuff hemostatic gauze directly into the bleeding wound, apply a pressure bandage, and take the patient to the regional trauma center
you will not be able to use a tourniquet because the wound is on the buttocks
you would not stuff cold packs directly into the wound or elevate it
Choose:
Your patient was cutting trees on his property with a manual bow saw when it slipped from its track and lacerated his right upper thigh. He is conscious, alert, and oriented with a 6-inch long laceration visible with moderate to severe dark red flowing blood present. His family is applying pressure to the femoral artery without successfully controlling the hemorrhage.
What type of bleeding do you suspect and how should you attempt to control it?
A. Arterial bleeding; direct pressure and pressure points
B. Venous bleeding; direct pressure with bulky trauma dressing
C. Capillary bleeding; tourniquet above the wound
D. Arterial bleeding; tourniquet over the wound
B
Venous bleeding presents as dark red due to the waste products that are contained within the blood from the lungs. It can be life-threatening if it remains uncontrolled. Direct pressure should be attempted first followed by a tourniquet if it is unsuccessful.

Which of the following body cavities is not spacious enough to allow for an internal bleed to progress to the point of causing hypotensive shock?
A. The thorax
B. The proximal leg
C. The skull
D. The abdomen
C
The skull is the only cavity in the body that is encased entirely by immovable bone. In addition, it is (ideally) filled with brain matter, making infiltration by large amounts of fluid impossible. Another way to look at it is by considering that since the other cavities (the incorrect answers) can expand while the skull cannot, the biggest problem with intracranial bleeding is increased intracranial pressure causing disturbances in homeostasis, not the actual amount of blood lost into it.
Choose:
You arrive on the scene of a reported shooting after the police have cleared the scene. A victim’s mental status has been declining at a rapid rate. Police report that he has become pale, confused, and seems to be breathing rapidly. You note an entrance wound on the left abdomen that is oozing a significant quantity of blood.
Which of the following would you also anticipate finding during the primary survey?
A. Shallow respirations
B. Bradycardia
C. Weak or absent peripheral pulses
D. Abdominal distention from internal bleeding
C
Severe blood loss presents with cold and pale skin, rapid breathing, tachycardia/bradycardia, confusion, weakness, cyanosis, loss of consciousness, and diminished peripheral pulses. THE MOST RELIABLE SIGN OF SEVERE BLOOD LOSS IS DIMINISHED OR ABSENT PULSES IN THE ANKLES AND WRISTS. The lack of these pulses implies the patient’s systolic BP is below 80. A carotid pulse is palpable until systolic goes below 60.
