Question

An infant with a total blood volume of 800 mL would start showing signs of shock when as little as ______ of blood is lost.

A) 100 mL
B) 200 mL
C) 50 mL
D) 150 mL

Answer 1

D) 150 mL. An infant with a total blood volume of 800 mL would start showing signs of shock when 150 mL of blood is lost.

Step-by-step explanation:

An infant with a total blood volume of 800 mL would start showing signs of shock when as little as 150 mL of blood is lost.

According to the information given, hypovolemic shock is a life-threatening condition that occurs when there is a loss of too much blood. Typically, a patient in circulatory shock will have increased heart rate but decreased blood pressure, decreased urine output, and may appear confused or lose consciousness.

Since the total blood volume of the infant is 800 mL, losing 150 mL of blood would constitute a significant loss and trigger signs of shock.
