Manif: low urine output, decreased BP / Pulse
Orthostatic Hypotension, thirst
^ Blood Osmolarity
-Hemodialysis - -Pharmokenetic excretion adversely affected
Monitor for digtoxicity / hyperkalemia / dillusional hyponatremia
3 requirements: access to blood, semipermeable membrane, dialysate
More Effective/ Shorter time
#1 Complication - Disequilibrium Syndrome causing ICP
Admin Anticonvulsants (Dilantin)
-Peritoneal Dialysis - -Monitor Albumin
#1 Complication - Peritonitis leads to septic shock
Ridge Board Like Abdomen
Cloudy Excretion - Infection
Interventions: heparinization required
weigh before / after, acquire baselines
^ protein intake - excreted at dialysis
Teaching: know signs for peritonitis, cloudy excretion, monitor
glucose for hyperglycemia
-Dialysis Air Embolism - -clamp catheter

Teaching: store unopened insulin vials in refrigerator or room temp
for 28 days
Draw regular insulin into syringe first when mixing insulins
Exercise decreases blood sugar levels
Sick Days: keep taking insulin
monitor glucose more frequently
watch for signs of hyperglycemia
**If in doubt if hyper / hypo glycemic, treat for hypoglycemia
