7) Your patient is a 23-year-old male cyclist who was impaled in the chest by a small tree branch as

he was riding on a trail. The branch has been removed on your arrival. You note a 1 cm wound in

the third intercostal space in the midclavicular line on the right. There is minimal bleeding. You

note air being sucked into the wound when the patient inhales, but air does not exit the wound on

exhalation. The patient is anxious and has a weak radial pulse of 116 that disappears on inhalation.

The patient's respiratory rate is 28, and breath sounds are absent on the right side. The patient is

sitting against a tree and refuses to lie down. You note jugular venous distention, but no tracheal

deviation. Which types of shock should you suspect in this patient?

A) Respiratory and hypovolemic B) Obstructive and respiratory

C) Hypovolemic and obstructive D) Distributive and respiratory

7)

8) The rapid trauma exam focuses on finding injuries that may cause shock. Components of the rapid

trauma assessment include all of the following EXCEPT:

A) Chest and abdomen for blunt or penetrating trauma.

B) Extremities for fractures.

C) Posterior for minor abrasions or lacerations.

D) Head for serious bleeding.

8)

9) Which of the following represents the correct sequence for controlling hemorrhage from an

extremity?

A) Pressure bandage, splinting, ice, elevation, tourniquet as a last resort

B) Direct pressure, elevation, ice, tourniquet

C) Direct pressure, elevation, pressure point compression

D) Pressure bandage, pressure point compression, elevation, ice

9)

10) Which of the following is NOT a benefit of PASG?

A) Increasing peripheral vascular resistance

B) An autotransfusion of up to 2000 ml of blood from the lower extremities

C) Decreasing the size of the vascular container

D) Minimizing movement of the pelvis and lower extremities

10)

11) Anaphylactic shock is a form of ________ shock.

A) cardiogenic B) hypovolemic C) neurogenic D) distributive

11)

12) Which of the following terms is best described as the loss of blood from the vascular space?

A) Hypovolemia B) Shock C) Hemostasis D) Hemorrhage

12)

13) Which of the following fluids is appropriate for the prehospital management of hypovolemic

shock?

A) 0.2% sodium chloride solution B) 0.45% sodium chloride solution

C) 5% dextrose in water D) Lactated Ringer's

13)

14) Which of the following is the preferred fluid for resuscitation in hemorrhagic shock?

A) Fresh frozen plasma B) Whole blood

C) Normal saline D) Lactated Ringer's

14)

15) In which of the following patients with hemorrhagic shock can you employ aggressive fluid

resuscitation?

A) A 45-year-old woman with a suspected ruptured ectopic pregnancy

B) A 50-year-old male with a stab wound to the right upper quadrant of the abdomen

C) A 26-year-old male with a gunshot wound involving the popliteal artery

D) A 38-year-old male with an open femur fracture and a developing bruise beneath the right

scapula following an assault

15)

16) When cells become hypoxic and the amount of carbon dioxide in them increases, reducing tissue

pH, which of the following occurs to restore homeostasis?

A) The precapillary sphincters open, increasing blood flow to the tissues. The postcapillary

sphincters remain closed so that increased hydrostatic pressure forces lactic acid into the

interstitial fluid, where it is buffered.

B) The sympathetic nervous systems constricts the capillary sphincters to prevent washout of the

accumulated lactic acid.

C) Mast cells release histamine, resulting in dilation of capillary sphincters and an increase in

tissue perfusion.

D) Mast cells release serotonin, resulting in dilation of the capillary sphincters and an increase in

tissue perfusion.

16)

17) Septic shock is a form of which of the following types of shock?

A) Distributive B) Neurogenic C) Hypovolemic D) Obstructive

17)

18) Under normal circumstances, at any given moment, most of the blood is in the ________ system.

A) hemopoetic B) capillary C) arterial D) venous

18)

19) Which of the following is a manifestation of orthostatic hypotension?

A) Your patient's pulse is 80 when she is supine, but 96 when she sits up.

B) Your patient's pulse is 76 when he is supine, but 88 when he sits up.

C) Your patient's blood pressure is 142/90 when she is supine, but 116/88 when she sits up.

D) Your patient's blood pressure is 150/100 when he is supine, but 134/90 when he sits up.
