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. Correct Answer-B
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) Blood pressure regulation becomes irregular.
D) The patient experiences tachycardia and a bounding pulse. Correct
Answer-A
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

A) Increased urine output
B) Decreased heart rate
C) Hyperactive bowel sounds
D) Cool, clammy skin Correct Answer-D
4. The nurse is caring for a patient who is exhibiting signs and
symptoms of hypovolemic
shock following injuries suffered in a motor vehicle accident. The nurse

the physician will promptly order the administration of a crystalloid IV

skin is warm
and dry. What does the ICU nurse recognize that that patient is probably
experiencing?
, A) Anaphylactic shock
B) Neurogenic shock
C) Septic shock
D) Hypovolemic shock Correct Answer-B
7. The intensive care nurse caring for a patient in shock is planning
assessments and
interventions related to the patients nutritional needs. What physiologic
process
contributes to these increased nutritional needs?
A) The use of albumin as an energy source by the body because of the
need for
increased adenosine triphosphate (ATP)
B) The loss of fluids due to decreased skin integrity and decreased
stomach acids due
to increased parasympathetic activity
C) The release of catecholamines that creates an increase in metabolic
rate and caloric
requirements
D) The increase in GI peristalsis during shock and the resulting diarrhea
Correct Answer-C
8. The nurse is trAnsferring a patient who is in the progressive stage of
shock into ICU from
