Foods, medications, and insects are common causes of ________.
A. septic shock
B. anaphylactic shock
C. psychogenic shock
D. neurogenic shock
B. anaphylactic shock
Distributive shock occurs when:
A. severe bleeding causes tachycardia in order to distribute blood to the organs faster.
B. an injury causes restriction of the heart muscle and impairs its pumping function.
C. widespread dilation of the blood vessels causes blood to pool in the vascular beds.
D. temporary but severe vasodilation causes a decrease in blood supply to the brain.
C. widespread dilation of the blood vessels causes blood to pool in the vascular beds.
To protect vital organs, the body compensates by directing blood flow away from organs that are more tolerant of low flow, such as:
A. the skin.
B. the brain.
C. the heart.
D. the lungs.
A. the skin.
When treating an 80-year-old patient who is in shock, it is important to remember that:
A. changes in gastric motility may delay gastric emptying, which increases the risk for vomiting.
B. compensation from the respiratory system usually manifests with increased tidal volume.
C. medications older patients take for hypertension often cause an unusually fast heart rate.
D. the older patient’s central nervous system usually reacts more briskly to compensate for shock.
A. changes in gastric motility may delay gastric emptying, which increases the risk for vomiting.
A 20-year-old male has a large laceration to his wrist. He is holding a blood-soaked towel over the wound, but it continues to bleed rapidly. You should:
A. administer high-flow supplemental oxygen.
B. apply a tourniquet proximal to the wrist.
C. apply pressure to the brachial artery.
D. wrap the towel with pressure bandages.
B. apply a tourniquet proximal to the wrist.
Your patient is in shock, but the body’s defense mechanisms are currently able to maintain adequate circulation. This is called ___________.
A. compensated shock
B. late shock
C. irreversible shock
D. decompensated shock
A. compensated shock
When should nonlifesaving interventions be performed for your multisystem trauma patient?
A. Immediately after the injuries are discovered
B. En route to the hospital
C. Prior to transport
D. During the primary assessment
B. En route to the hospital
Pulmonary edema and impaired ventilation occur during:
A. neurogenic shock.
B. anaphylactic shock.
C. cardiogenic shock.
D. septic shock.
C. cardiogenic shock.
You suspect your patient is in shock. You note the patient’s skin is pale. This is likely due to ___________.
A. an increased heart rate
B. peripheral vasodilation
C. hypothermia
D. peripheral vasoconstriction
D. peripheral vasoconstriction
