ATI Med Surg test questions Shock and Multiple Organ Dysfunction Syndrome
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 patient's
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
D) Hemorrhage occurs as a result of trauma, depriving vital organs of adequate perfusion. - Ans: B
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.
In an acute care setting, the nurse is assessing an unstable patient. When prioritizing
the patient's 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) Blood pressure regulation becomes irregular.
D) The patient experiences tachycardia and a bounding pulse. - Ans: A
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
Hypovolemic shock is characterized by a decrease in intravascular volume. Cardiac
output is decreased, blood pressure decreases, and pulse is fast, but weak.
