Colloid.
C)
Lactated solution.
D)
Hypotonic solution.

Question 12
Which of the following statements regarding colloid statements is TRUE?
A)
Colloids exert osmotic pressures that draw fluids into the vascular space for volume replacement.
B)
Colloids readily diffuse into the extravascular space for fluid replacement.
C)
Colloids do not contain proteins or sugars; therefore, they do not make suitable solutions for volume replacement.
D)
Colloids are inexpensive, have and long shelf-life, and are widely used among most EMS communities.
colloids exert osmotic pressure that draw fluids into the vascular space for volume replacement
