Shock and Multiple Organ Dysfunction Syndrome
Test Questions
,Shock and Multiple Organ Dysfunction Syndrome Test
Questions
1.
A nurse in the ICU is planning the care of a patient who is being treated for shock. Which of the
following statements best describes the pathophysiology of this patients health problem?
A)
Blood is shunted from vital organs to peripheral areas of the body.
B)
Cells lack an adequate blood supply and are deprived of oxygen and nutrients.
C)
Circulating blood volume is decreased with a resulting change in the osmotic pressure gradient.
D)
Hemorrhage occurs as a result of trauma, depriving vital organs of adequate perfusion.
Ans:
B
Feedback:
Shock is a life-threatening condition with a variety of underlying causes. Shock is caused when the cells
have a lack of adequate blood supply and are deprived of oxygen and nutrients. In cases of shock, blood
is shunted from peripheral areas of the body to the vital organs. Hemorrhage and decreased blood
volume are associated with some, but not all, types of shock.
2.
In an acute care setting, the nurse is assessing an unstable patient. When prioritizing the patients care,
the nurse should recognize that the patient is at risk for hypovolemic shock in which of the following
circumstances?
A)
Fluid volume circulating in the blood vessels decreases.
B)
There is an uncontrolled increase in cardiac output.
C)
, Shock and Multiple Organ Dysfunction Syndrome Test
Questions
Blood pressure regulation becomes irregular.
D)
The patient experiences tachycardia and a bounding pulse.
Ans:
A
Feedback:
Hypovolemic shock is characterized by a decrease in intravascular volume. Cardiac output is decreased,
blood pressure decreases, and pulse is fast, but weak.
3.
The emergency nurse is admitting a patient experiencing a GI bleed who is believed to be in the
compensatory stage of shock. What assessment finding would be most consistent with the early stage of
compensation?
A)
Increased urine output
B)
Decreased heart rate
C)
Hyperactive bowel sounds
D)
Cool, clammy skin
Ans:
D
Feedback:
In the compensatory stage of shock, the body shunts blood from the organs, such as the skin and
kidneys, to the brain and heart to ensure adequate blood supply. As a result, the patients skin is cool
and clammy. Also in this compensatory stage, blood vessels vasoconstrict, the heart rate increases,
bowel sounds are hypoactive, and the urine output decreases.
