Nse 22 nursing practice ii: acute and chronic care. Iv therapy and iv medication administration: discuss the purpose of intravenous therapy; Purpose of iv therapy: to replace or correct fluid and electrolytes, maintain or restore fluid balance (dehydration/shock, route for medication administration, to transfuse blood or blood components, to provide nutritional support (tpn, lipids) Larger molecules that can not diffuse through capillary walls: stays in vascular system, blood and blood products, 5% albumin, fresh frozen plasma (ffp, synthetic colloids, dextran, pentaspan, voluven. Crystalloids: small molecules that diffuse through capillary walls, depending on solute concentration, fluids may be: isotonic, hypotonic, hypertonic, explain the uses of the different types of iv solutions and discuss the rationale for use; Description: osmolarity is lower than serum osmolarity, fluid shifts into the cells and interstitial space. Examples: 0. 45% saline (0. 45%s) (154) from the vasculature, hydrates cells but reduces fluid in circulatory system, used with caution can cause an increase in intracranial pressure (icp)
