NUR 3191 FALL 2016 STUDY GUIDE- EXAM # 1
Routes of medication administration:
1. Enteral (GI) absorbed into systemic circulation through the mucosa of
stomach and small and large intestine
 Oral absorbed from intestinal lumen into the blood system and
transported to the liver.
 ENTERIC COATING ALLOWS ABSORPTION TO OCCUR IN
SI
 Anticholinergic slow GI transit time
 When portions of SI are removed → short bowel syndrome,
reduces absorption
 Bariatric surgery → reduces size of stomach and causes gastric
dumping
 Sublingual and buccal → bypass liver, go directly into bloodstream
 Rectal can be enteral and topical
2. Parenteral →bypass first pass effect of the liver
a. ID → superficial
b. SQ → fatty layer
c. IM → absorbed quicker than subcutaneous because muscles
have greater blood supply
d. IV→ intravenous
3. Topical → bypass liver first pass effect, except for rectal
a. transdermal → used to deliver constant amount of drug, like
nitroglycerin patches
b. Inhaled → goes to lungs
First pass-effect: initial metabolism in liver before systemic circulation
Reduces the bioavailability of the drug to less than 100%
