PN1005 Pharmacology Midterm Exam
Questions And Answers Latest 2025
Pharmacokinetics -
correct answer ✅How the body affects the drug
4 stages of pharmacokinetics -
correct answer ✅1. Absorption
2. Distribution
3. Metabolism
4. Excretion
Absorption -
correct answer ✅what happens to a drug from the time it enters
the body until it enters the circulating fluid; intravenous
administration causes the drug to directly enter the circulating
blood, bypassing the many complications of absorption from other
routes.
Distribution -
correct answer ✅The movement of drug to and from the

Controlled Drugs and Substances Act -
correct answer ✅Class 1: heroin
Class 2: hydromorphone
Class 3: Codeine
Biotransformation (metabolism) -
correct answer ✅the process by which drugs are changed into
new, less active chemicals
first pass effect -
correct answer ✅a phenomenon in which drugs given orally are
carried directly to the liver after absorption, where they may be
largely inactivated by liver enzymes before they can enter the
general circulation; oral drugs frequently are given in higher doses
than drugs given by other routes because of this early breakdown
Protein bound drugs -
correct answer ✅Affects the distribution of a drug; when the drug
is bound to protein, it is unable to pass through capillary walls; may
cause drug toxicity. when the patient has a lower-than-expected
protein level, the distribution of the drug is altered.
