**PN1003 - SESSION 3 EXAM QUESTIONS WITH
COMPLETE SOLUTIONS
Intravenous Therapy (IV)
the delivery of medication, nutrition, or fluids through a person's vein
- is used to maintain or restore fluid balance when oral replacement is inadequate or
impossible to maintain or replace electrolytes
total parenteral nutrition (TPN)
nutrient-complete solution given directly into bloodstream when person cannot eat by
mouth
the btwo types of intravenous solutions
crystalloid solutions
colloid solutions
Crytalloid Solutions
are divided into hypertonic solutions and isotonic solutions and hypertonic solutions
hypotonic solutions
contains fewer dissolved substances compared with plasma
re-hydrates clients experiencing fluid deficits; therefore they are administered to clients
experiencing fluid losses in excess of fluid intake such as those who have diarrhea or
are vomiting
isotonic solutions
, contains the same concentration of dissolved substances as os normally found in
plasma
- maintains fluid balancen when clients temporarily cannot eat or drink
hypertonic solution
is more concentrated than body fluids
- draws fluids inside the intravasculat compartment from the more dilute areas in the
cells and interstitial spaces. used to reduce cerebral edema, expand circulatory volume
rapidly, treat low serum sodium
Colloid solutions
used to replace circulating blood volume because suspended molecules in the solution
pull fluid from another compartments in the body.
most common colloid solutions
whole blood and packed cells
Plasma
Liquid part of blood
Coagulopathies
bleeding disorders that involve platelets or clotting factors
Albumin
is a large plasma protein that does not normally love across semipermeable
membranes like those in capilaries.
Platelets
