Quiz: What will the nurse identify as symptoms of hypovolemic shock in a patient?
Note: Credit will be given only if all correct choices and no incorrect choices are selected.
Standard Text: Select all that apply.
1. Temperature of 97.6°F (36.4°C)
2. Restlessness
3. Decrease in blood pressure of 20 mm Hg when the patient sits up
4. Capillary refill time greater than 3 seconds
5. Sinus bradycardia of 55 beats per minute

, Ans: Correct Answer: 2,3,4
Rationale 1: Fever will increase oxygen demands but is unrelated to hypovolemic shock
unless prolonged fever has caused severe dehydration, reducing the circulating blood
volume. Hypovolemic shock reduces temperatures by peripheral shunting of blood away
from the extremities and reducing the core metabolic rate.
Rationale 2: Due to decreased blood flow to the brain and peripheral areas when blood is
shunted to maintain the vital organs, cerebral hypoxia occurs, leading to a change in
mental status.
Rationale 3: Orthostatic hypotension is a manifestation of hypovolemic shock.
Rationale 4: Due to decreased blood flow to the brain and peripheral areas when blood is
shunted to maintain the vital organs, capillary refill time will be reduced.
Rationale 5: Bradycardia is not present. The compensatory response is to increase the
heart rate to circulate the blood faster to make up for the fluids that are not present in
hypovolemic shock.
Quiz: Which laboratory finding should cause the nurse to suspect that a patient is
developing hypovolemic shock?
1. Serum sodium of 130 mEq/L (130 mmol/L)
2. Metabolic acidosis validated by arterial blood gases
3. Serum lactate of 3 mmol/L
4. SvO2 greater than 80%

, Ans: Correct Answer: 2
Rationale 1: The sodium level in hypovolemic shock is elevated above the normal values of
135 to 145 mEq/L, not reduced.
Rationale 2: Metabolic acidosis is present due to an accumulation of carbonic acid, leaving
a bicarbonate deficit from decreased tissue perfusion.
Rationale 3: Serum lactate is greater than 4 mmol/L as a result of tissue ischemia, hypoxia,
and breakdown from decreased blood flow with hypovolemic shock.
Rationale 4: SvO2 (mixed venous oxygen saturation) would be less than 60% due to
decreased circulating blood volume or decrease in cells to carry the oxygen. Therefore, O2
is carried less efficiently and decreased, not increased.
Quiz: The nurse recognizes that which patient would be most likely to develop
hypovolemic shock? A patient with:
1. Decreased cardiac output
2. Severe constipation, causing watery diarrhea
3. Ascites
4. Syndrome of inappropriate ADH (SIADH)
