MULTIPLE CHOICE

 

1. What are the four types of shock?

a.	Multiple organ, cardiogenic, renal, and anaphylactic
b.	Cardiogenic, renal, hypovolemic, and septic
c.	Renal, hypervolemic, obstructive shock, and neurogenic
d.	Hypovolemic, cardiogenic, obstructive shock, and vasogenic

 

 

ANS:  D

The four large categories of shock are hypovolemic (low-circulating volume), cardiogenic (low-cardiac output), obstructive (occluded vascular pathway), and vasogenic (massive vasodilation).

2. Although several life-supporting systems of the body are involved in the pathophysiologic characteristics of shock, shock itself results from failure of which system?

a.	Circulatory
b.	Endocrine
c.	Neurologic
d.	Respiratory

 

 

ANS:  A

When the heart fails as a pump, the lack of tissue perfusion follows and deprives all the body’s cells of oxygen and the removal of wastes.

3. A nurse is assessing a patient who is in shock. What should the nurse be aware that one common sign will be, regardless of the cause of the shock?

a.	The skin is cool and dry with cyanotic nail beds.
b.	The skin is cool and moist with cyanotic nail beds.
c.	The nail beds are reddened, and the skin is moist and warm.
d.	The nail beds are reddened, and the skin is dry and warm.

 

 

ANS:  B

Venous blood pools in the extremities of the fingers as a result of the lack of adequate perfusion of tissues, which makes the skin cool and moist from a lack of oxygen and waste exchanges.

4. What should a nurse assessing a patient in the progressive stage of shock expect to find?

a.	Bounding pulse, decreased respirations, and decreased blood pressure
b.	Bounding pulse, shallow respirations, and significantly increased blood pressure
c.	Thready pulse and deep respirations with decreased blood pressure
d.	Thready pulse and irregular respirations with increased blood pressure

 

 

ANS:  C

When the heart fails as a pump, the pulse is weak; the respirations increase in an effort to decrease the carbon dioxide level; and, with less volume being pumped, the blood pressure falls.
