a. intravenous crystalloids.
b. blood product administration.
c. parenteral nutrition (PN).
d. colloid administration.
C
Parenteral nutrition (PN) is a nutritionally adequate solution consisting of glucose, other nutrients, and electrolytes administered through a central venous catheter. This intervention meets nutritional needs when the GI tract is nonfunctional. Fluid and electrolytes may be replaced through infusion of fluids intravenously (IV), meaning directly into veins. Parenteral replacement includes PN, IV fluid and electrolyte therapy (crystalloids), and blood product (colloids) administration. The goal of IV fluid administration is to correct or prevent fluid and electrolyte disturbances.
