Chapter 19: Shock || Questions and 100% Accurate Answers.
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 correct answers 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 correct answers 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. correct answers 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 correct answers 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.

5. What should a nurse expect of a patient's respirations caused by the falling blood pressure and
impaired blood circulation during the refractory stage of shock?
a. Rapid and deep
b. Rapid and shallow
c. Slow and deep
d. Slow and shallow correct answers ANS: D
During the refractory stage of shock, as the body systems are failing, the respirations become
slow, shallow, and irregular. Death is imminent at this stage.

6. A licensed practical/vocational nurse (LPN/LVN) is assisting in developing a nursing care
plan for a patient in shock. Which nursing diagnosis should be included?
a. Increased cardiac output, related to hypertension
b. Increased cardiac output, related to hypotension
c. Decreased cardiac output, related to hypovolemia
d. Decreased cardiac output, related to hypertension correct answers ANS: C
Decreased amount of blood is ejected from the heart because of a decreased volume of fluid in
the intravascular compartment.

7. How does the intraaortic balloon pump (IABP) assist a patient who is in cardiogenic shock to
increase cardiac output?
a. Provides generalized vasoconstriction
b. Inflates during the diastole phase
c. Constricts the vena cava
d. Adds hypertonic fluid to the circulating volume correct answers ANS: B
The IABP inflates during diastole (relaxation) phase and deflates during the systole (constriction)
phase, which improves cardiac output.

8. A nurse is explaining to a family member the pathophysiologic characteristic of vasogenic
shock. What information should the nurse include?
a. The intravascular compartment fills beyond capacity, allowing fluid to leak out, compressing
vital organs.
b. The circulating volume causes excessive constriction of the vessels, causing blood pooling.
