- 3-4 times a week --> rapid fluid shift
- client must have fistula
- Complications: Disequilibrium, hypotension peritoneal dialysis - uses the peritoneal membrane as the filter instead of a machine --> Dialysate is infused into the peritoneal cavity, dwells for 6 hours, fluid is drained taking the toxins away with it --> drainage should be clear - turn side to side if decreased fluid return phototherapy - a therapy that involves repeated exposure to bright light --> helps breakdown bilirubin so it can be excreted in the feces --> Monitor the level and distance from the light if overhead therapy is being used pace makers - that's placed in the chest or abdomen to help control abnormal heart rhythms. This device uses electrical pulses to prompt the heart to beat at a normal rate Contractility - strength of contraction of heart muscle stroke volume - The amount of blood ejected from the heart in one contraction. cardiac output - The volume of blood ejected from the left side of the heart in one minute. Post-op care - 1. Assessment (ABCs, bleeding risk?, Infection?, Vitals?)
- Pain management
- Wound care/Dressing changes
- Mobility (Early ambulation)
- Respiratory care
- Nutrition (Diet: High protein, Zinc, Iron, Vit. A,B,C,E,K)
- Client advocacy ( Education, Emotional support)
- Discharge planning Peripheral IV access - --> Allows for administration of medication, fluids and blood product IV --> Short term --> Changed every 72-96 hours or hospital policy Central IV access - --> Larger volume of fluid to be given
--> may draw blood specimens --> PICC, Nontunneled central venous cath., Tunneled Central Venous cath. TPN (total parenteral nutrition) - Highly concentrated, hypertonic lots of minerals less water Calories, fluids & nutrients Central venous access device required you have to have a central line not a peripheral line it would burn the tissue* also you will use a filter --> check blood glucose every 4-6 hours, daily weight --> Dont turn off suddenly Immunization schedule - Birth: Hep B 2 mos: Hep B, ROTAVIUS, DTaP, Hib, Pneumococcal, Poliovirus 4 mos: Rotavirus, DTaP, Hib, Pneum, Poliovirus 6 mos: Hep B, DTaP, Hib, Pneum, Poliovirus 12 mos: MMR, VAR, Hep A, Influenza, Hib 11-12 YEARS: Tdap, Meningococcal, HPV high risk behaviors - behaviors that expose a person to an unnecessarily high degree of physical or psychological jeopardy Ginkgo biloba - memory enhancement bleeding risk Ginseng - Mental performance bleeding risk Saw palmetto - Benign prostatic hyperplasia (BPH) bleeding risk St. John's Wort - Depression, Insomnia HTN, decrease effect of anticoagulants, Interacts w/antidepressants, steroids' and digoxin Licorice extract - Ulcers, Bronchitis Normal adult vital signs - Temperature: 96.8-99.1 oral BP: 120/80 Pulse rate: 60-100 BPM RR: 12-18 resp/min
Pulse: 60-100 bpm Normal pediatric vital signs - Head to toe assessment - A complete assessment of the patient, one that includes all systems Low fowlers - 15-30 degrees Semi fowlers - 30-45 degrees Fowlers - 45-60 degrees High-fowlers - 60-90 degrees Othrostatic hypotension - Dizziness due to sudden changes in posture (usually found in elderly), cause by slow nervous system response. When you suddenly get up from a resting position, your blood pressure drops. supine - lying on the back --> lookout for skin breakdown Prone - lying face down --> allows for full extension of the hip/knee joints Right lateral recumbent position - lying on the patient's right side; left knee may be drawn upward (also called right lateral decubitus position and right Sims position when knee is drawn upward) --> promote gastric emptying Left lateral recumbent - Recovery position, patient ends up on their left side, with their left arm folded under their head --> promotes an increase of blood flow to the placenta Trendelenburg position - A position in which the patient's feet and legs are higher than the head --> promotion of venous return( more blood back to the heart), postural drainage Reverse Trendelenburg - -entire bed is tilted with the foot of the bed lower than the head -position promotes gastric emptying and prevents esophageal reflux Sims - body position in which a person is lying on his left side with the upper knee flexed and raised toward the chest traction positioning - uses a pulling force to realign a bone
stages of pressure ulcers - ●Stage I - persistent redness; skin is intact with visible, non blanchable redness over a localized area, typically over bony prominence; changes in skin temperature, tissue consistency and sensation (pain, itching) ●Stage II - involves the dermis with partial thickness loss which presents as shallow open ulcer that can be shiny or dry; can also present as a blister that is intact or open/ruptured; wound bed is red pink color without slough or bruising ●Stage III - full thickness tissue loss with subcutaneous fat possibly visible; bone, tendon or muscle are not exposed or directly palpable ●Stage IV - full thickness tissue loss with bone, tendon, or muscle visible NG tube insertion - 1. check order, gather equipment, introduce yourself, identify Pt., provide privacy, explain procedure, hand hygiene, gloves.
- solicit help & consider restraints prn
- position child in fowler's position
- (nasogastric)determine length of tube measure from the tip of the nose to the tragus of the ear to the xiphoid process & mark appropreately 5.(orogastric)determine length of tube measure from the mouth to the tragus of the ear to the xiphoid process & mark appropreately
- apply lubricant to the tip of the tube
- for orogastric tube insert tube into mouth with neck hyperextended & advance it toward the back of the throat, continue until mark is reached
- nasogastric tube insert tube into nose with neck hyperextended & advance straight, if resistance is met increase pressure slightly or rotate tube, continue until mark is reached
- use a syringe to aspirate a small amount of gastric content, test the PH of the contents using using the litmus paper ( a PH of 3 or less indicates gastric contents)
- secure the tube with tape or other product to hold the tube in place NG tube placement - xray to confirm proper placement, monitor NG output (color and amt), monitor nasal skin around tube, monitor tubing for kinks & "plugs", continue to assess BS's and abdominal girth, pain, **aspirate contents & irrigate the tube w/ 30 mL of NS q 4 hrs or as ordered by hcp Enemas - The injection of liquid into the rectum through the anus for cleansing or stimulating bowel movement.
