Question 1: Pharmacokinetics - The process in which
medications move through the body
CORRECT ANSWER: The process in which
medications move through the body
Question 2: What are the 4 phases of pharmacokinetics? -
absorption, distribution, metabolism, excretion
CORRECT ANSWER: absorption, distribution,
metabolism, excretion
Question 3: Absorption - happens with drug movement
from the GI tract into the bloodstream. Most meds are taken by mouth.
CORRECT ANSWER: happens with drug movement
from the GI tract into the bloodstream. Most meds are taken by mouth.

Question 4: Oral absorption - Takes awhile to get
absorbed because it has to go through the GI system, Usually takes 2-4 hours, •Enteric coated, aspirin - hard on stomach, can not crush pill, •Extended release, absorbed in the small intestine
CORRECT ANSWER: Takes awhile to get absorbed
because it has to go through the GI system, Usually takes 2-4 hours, •Enteric coated, aspirin - hard on stomach, can not crush pill, •Extended release, absorbed in the small intestine
Question 5: IM absorption - Absorbed 1-2 hours
CORRECT ANSW ER: Absorbed 1-2 hours
Question 6: IV absorption - Absorbed 30-60 minutes
CORRECT ANSWER: Absorbed 30-60 minutes
Question 7: dissolution - Dissolution happens when a po
medication breaks down into particles, disintegrates, and dissolves to combine with liquid so absorption from the

GI tract into the bloodstream occurs. Liquid medications are absorbed faster than solids. Food can interfere with the absorption of drugs.
CORRECT ANSWER: Dissolution happens when a po
medication breaks down into particles, disintegrates, and dissolves to combine with liquid so absorption from the GI tract into the bloodstream occurs. Liquid medications are absorbed faster than solids. Food can interfere with the absorption of drugs.
Question 8: Drugs that resist dissolution - Parenteral
medications (SL, eyedrops, inhalants, transdermal) do not pass through the GI tract. Enteric coated medications are designed to resist disintegration until the pill reaches the small intestine. EC and sustained release meds should not be crushed.
CORRECT ANSWER: Parenteral medications (SL,
eyedrops, inhalants, transdermal) do not pass through the GI tract. Enteric coated medications are designed to resist disintegration until the pill reaches the small intestine. EC and sustained release meds should not be crushed.

Question 9: Factors that affect absorption - •Lack of
muscle and increased fat changes medicine absorption, •Food consumption - will change medicine potency (delayed), •Stress - Exercise, medicine goes to muscle, •pH - Medicine is made for acidic environments, •Antacid changes absorption, •Taken alone so it doesn't change the action
CORRECT ANSWER: •Lack of muscle and increased
fat changes medicine absorption, •Food consumption - will change medicine potency (delayed), •Stress - Exercise, medicine goes to muscle, •pH - Medicine is made for acidic environments, •Antacid changes absorption, •Taken alone so it doesn't change the action
Question 10: Excipients - Fillers and other substances that
make up tablets as a pill is not 100% drug. Sometimes an excipient enhances the absorption of a drug such as with PCN, which is not well absorbed from the GI tract.Adding Na to PCN, which makes it penicillin sodium, will increase the absorption of PCN
CORRECT ANSWER: Fillers and other substances that
make up tablets as a pill is not 100% drug. Sometimes an
