Antacids
-GERD and Pepticulcerdisease
-NursingConsideration
= changesph of stomach / small intestine
Give 1hr before or2hrs after meal
Decreasesdigoxinandantibioticsabsorption
Increase Levodopa
= effectsoccurby alteringpH

Locally acting anti-diarrheal
- Action= absorbsexcesswater,irritants,
bacteria
- Producessoftstool

UTI
-2nd
mostcommon conditiontreatedwith
antibiotics
-Anatomy= kidney,ureter,urinarybladder,
urethra,prostate (male)

JSy
*Ulcerative colitisrelatedtoRA
2 Main UsesofChemotherapy
-tocontrol/cure the disease
-Palliationtocontrol sx
-majors/e = monitorN/V,diarrhea,bone
marrow suppression
-Nx Consideration=VS,s/sx of infection(BM
suppression),bleeding,anemia,
manage pain,manage N/V
BM Suppression
-BM= bloodcell are manufactured
-deccell production,responsible forproviding
immunity(leucocytes),carryingO2(rbc),
bloodclotting(thrombocytes)
Timolol
-adrenergicblocker
-decaqueoushumorwhichdecintraocular
pressure inopenangle glaucoma

instillationcanleadtosystemicabsorption
of meds
NSAIDS
