Fluid Assessment: Deficit: - BP low - Pulse fast (compensation) - Increased vascular volume - Neck veins not too visible - Mucous membranes dry - Decreased body weight 2. Fluid Assessment: Overload: - Elevated BP - Pulse elevated - Bounding neck veins - Increased vascular volume (edema, pulse bounding) - Mucous membranes normal - Body weight increased 3. Reasons for IV Therapy: - Maintain or restore fluid volume - To replace or correct fluids and electrolytes - Route for medication administration - To transfuse blood or blood components - To provide nutritional support (TPN and lipids) 4. What is IV Therapy? IV therapy is a prescribed therapy based upon the pt's condition and treatment plan 5. Essentials for Nurses in IV Therapy: - Assess/reassess PIV completely based on policy - Follow hospital guidelines and policy to establish and maintain - Understanding of ordered IV fluids in context of pt's condition - Provide pt education as indicated 6. Nursing Concepts for Fluid Management: - Lab findings - Overload/deficit - Fluid restriction - Intake/output - 24-hour fluid balance 7. Common IV Solutions: 1) Isotonic 2) Hypertonic 3) Hypotonic 4) Plasma Expander (Colloids) 8. Isotonic Solutions: - Generally, have a 'normal' osmolarity as serum and other body fluids - STAYS where it is infused - intravascular system - The least irritating to endothelial lining of vein wall 9. Examples of Isotonic Solutions: - Ringers Lactate (RL or LR) - 275 mOsm/L - Normal Saline (NS) - 308 mOsm/L - 5% Dextrose in Water (D5W) - 252 mOsm/L - 5% Albumin - 308 mOsm/L 10. Hypertonic Solutions: - Osmolarity is higher than serum osmolarity - PULLS fluid from interstitial and intracellular compartments - Greatly expand intravascular compartment (watch for circ. overload) - Pull from cellular compartment - May be used cautiously to decrease edema (cerebral, pulmonary, peripheral) - Do NOT give to pts with renal or cardiac impairment - Increased risk of vessel damage 11. Examples of Hypertonic Solutions: - 5% Dextrose in 0.45% Saline (D5/1/2S) - 406 mOsm/L - 5% Dextrose in NS (D5NS) - 560 mOsm/L - 10% Dextrose (D10W) - 3% NS - 1025 mOsm/L - 25% Albumin - 1500 mOsm/L
