A protein-containing fluid that has high molecular weight and does NOT readily diffuse across a cellular membrane is know as a:
a. Hypotonic solution
b. Crystalloid solution
c. Lactated solution
d. Colloid
d
Rationale: a. Hypotonic solutions readily cross a cellular membrane and do not expand volume because of low molecular weight.
b. Crystalloid solutions do not contain proteins and do not remain in the vasculature long.
c. A lactate solution contains a buffer.
