Bind to muscarinic receptors within parasympathetic nervous system
relaxes urinary sphincter, contracts detrussor muscle of bladder, increase bladder tone
Rx: non-obstructive Urinary Retention; neurogenic bladder= nerves arent stimulating bladder
se: vasodilation/hypotension, abdominal cramp (cholinergic action; caution bronchoconstriction
Nsg: will cause voiding within 30-90 minutes
monitor BP, P, R and I&O
monitor for excess cholinergic effects- salivation, sweating, flusing, n/v/d
Take 1 hr ac or 2 hr pc; dose titered to reach effectiveness (altered to get the side effects needed)
oxybutynin (Ditropan, Ditropan XL
MUSCARINIC ANTAGONISTS/PARASYMPATHOLYTIC/ MUSCARINIC BLOCKERS/ ANTICHOLINERGIC/ ANTISPASMOTIC

Rx: urge incontinence, overactive bladder, post-op transurethral procedures, nocturia
se: anticholinergics, esp dry mouth, constipation, dry eyes, dyspepsia
NSG: void before taking med to minimize urinary retention
epotein alfa / Erythropoietin
HRMSYOPOIRYIV=Build blood
stimulate production of RBCs, but need iron, folic acid, Vit B12 to work (lack of any will cause anemia)
Low oxygen and anemia stimulate erythropoietin release normally from kidney--> bone marrow
use to increase HCT of anemia secondary to CRF; HCT increases in 2-4 weeks
Administered IV or SC; Do not shake vial
se: may increase BP
Nsg: monitor HCT and BP; check clotting in AV fistula "feel the trill
No intrinisic factor=B12, shots for life

ferrus sulfate/ Feosol
HEMATOPOIETIC
