NUR 120 Essentials II FINAL Study Guide w1-w5 – Fluid & Electrolytes/ ABG’s IV solutions Hypertonic solution  Greater osmolality causes cell shrinking as water is pulled out of the cell into blood.  Administered slowly or can cause intravascular overload. Monitor for overload.  Carefully monitor serum sodium, lung sounds, and BP.  D10 – dextrose in water  Dextrose 5% in 0.45% or half strength NaCl.  D5NS - Dextrose 5% in 0.9% NaCl – used to treat hyponatremia and hypovolemia.  3% sodium – VERY hypertonic  Used in pt w head injury to decrease swelling.  Gatorade Isotonic solution  Same osmolality maintains equilibrium or balance. No shrinking or swelling.  0.9% NaCl.  Lactated ringers.  D5W: Dextrose 5% in water – metabolized quick leaving free water to be absorbed.  Ideal for pt w ECF volume deficit Hypotonic solution  Lower osmolality, cause swelling as water moves into cell.  Provides more water than electrolytes and dilutes the ECF  0.45% or half strength NaCl – replenishes cellular fluid.  Monitor closely for intravascular fluid loss, hypotension, edema, and LOC changes.  Coke
