| Nursing responsibilities for IV sites | assess  site whenever in room, document at least every 8 hours, site CDI (clean,  dry, intact), sterile technique, changine tubing and solution,  awareness of complications, awareness of fluid types, 5 rights | 
| Complications of IV therapy | Pain and irritation, infiltration and exravasion, occlusion, loss of patency, phlebitis, fluid overload | 
| Infliltration | seepage of IV fluids into tissue when IV cath penetrates vein | 
| Extravasion and Infiltration Assessment | swelling, pain, cool to touch, decreased flow, wet dressing, no back flow. | 
| Causes of Infiltration and Extravasion | catheter permeates vein, poor taping of site, over manipulation | 
| Intervention for Infiltration and Extravasion | Remove IV, cool compress | 
| Occlusion causes | kinked tubing, patient lying on tubing, infusion too slow | 
| Occlusion assessment | IV stops dripping | 
| Occlusion intervention | milk IV, aspirate, irrigate (if no resistance OK, if resistance may be clot> | 
| Occlusion Prevention | don't let IV run dry, flush periodically with 1-5 cc of NSS and before and after any intermittent IV therapy. | 
| Phlebitis Causes | bacterial, chemical, mechanical | 
| Phelebitis Intervention | remove IV, cool compress | 
| Phlebitis Assessment | erythemia, pain or burning, warmth, edema, cordlike vein. | 
| Phlebitis possible causes: | IV left in too long, irritating fluids, clot at tip of cannula, cath too large for vein | 
| Crystalloids | clear fluids, dextrose or saline, can be Iso, Hypo or Hyper tonic | 
| Colloids | cloudy, yellowish, used to raise osmotic pressure, Dextran is clearish | 
| Isotonic IV | same tonicity as body 0.9% NSS | 
| Reasons to give an Isotonic IV | Hypotension (increases BP), Hypovolemia | 
| Complications of Isotonic IV | fluid overload | 
| Examples of Isotonic Solutions | 0,9% NSS, D5W(isotonic in bottle, hypotonic in body), Lactated Ringers | 
| Reasons to give a Hypotonic IV | Will cause fluid to shift from intravascular to intracellular space. | 
| Indications for Hypotonic IV | dehydration | 
| Hypotonic Solutions | .45% sodium chloride, 5%dextrose water (becomes hypotonic in body) | 
| Complications of hypotonic solution | May cause edema | 
| Reasons to give a hypertonic IV | low bp, slight edema but not w/CHF, pulls fluid from intracellular space to intravascular space | 
| Hypertonic IV Solution | Not as strong as Albumin, 10% Dextrose in Water D10W, 5% normal saline, D5 Ringers Lactate | 
| Complications of Hypertonic IV | more fluid in bloodstream can cause circulatory overload. | 
| PCA stands for: | Patient Controlled Analgesia | 
| 3 settings of PCA | drug dosage, lockout period, basal rate | 
| Central Venous Therapy Indications | inadequate  vascular access, complex treatment regimes, hyperosmolar infustions ie  parenteral nutrition, irritating or vesicant druges, (ie. dopamine  cancause necrosis) rapid absorption, long term therapy. | 
| Contraindications for Central venous therapy | altered  skin integrity, anomalies of central vasculature, cancer in area,  coagulopathies, fractured clavicle, septicemia, radiation to insertion  site | 
| Common insertion pathways for Central Venous Therapy | subclavian, jugular, femoral vein, cephalic vein(is peripheral but the line runs to central area) | 
| Risks and Complications of Central Venous Therapy | Air embolism, pneumothorax, sepsis,chest pain, confusion, hypotension, dyspnea, pallor, tachycardia, tachypnea, unresponsiveness | 
| Components of Intravenous Nutritional Support | amino acids, carbohydrates, electrolytes, minerals, vitamins, lipids, other (ie insulin) | 
| Lipids in Intravenous Nutritional Support | lipids are administered via Piggy back.  (white, thin liquid) | 
| Cautions for IV nutritional support | not  refrigerated, observe for spoilage (fat on top, discoloration),  expiration dateNo filter. , must be infused on IV pump, glucose  monitored, gradual weaning. Daily weights, | 
| Complications for IV nutritional support | hypoglycemia, hyperglycemia, dehydration, infection | 
| Reasons to give IV Nutritional Support | bowel  surgery, chronic weight loss, bowel rest, coma, excess nitrogen loss,  hepatic or renal failure, malnutrition, low serum albumin,  hypermetabolic states |
