100% Verified Nursing Study Guide
Q1. In pharmacology, which principle explains how drugs move from
administration site into the bloodstream?
A. Distribution
B. Absorption
C. Metabolism
D. Excretion
Absorption is the process of drug entry into systemic circulation.
Q2. Which drug administration route bypasses the gastrointestinal tract and
provides rapid systemic effects?
A. Oral
B. Intravenous
C. Rectal
D. Sublingual
IV administration delivers drugs directly into circulation.
,Q3. Which pharmacokinetic phase describes how drugs are transported throughout
body tissues and fluids?
A. Absorption
B. Distribution
C. Metabolism
D. Excretion
Distribution moves drugs to target tissues.
Q4. Which organ is primarily responsible for drug metabolism and
biotransformation in the body?
A. Kidney
B. Liver
C. Lungs
D. Skin
The liver metabolizes most drugs via enzymes.
Q5. Which pharmacokinetic process eliminates drugs from the body, mainly
through urine and feces?
A. Absorption
, B. Distribution
C. Metabolism
D. Excretion
Excretion removes drugs via kidneys and other routes.
Q6. Which drug administration route provides the slowest onset but longest
duration of action?
A. IV
B. IM
C. Oral
D. Sublingual
Oral drugs act slowly but last longer.
Q7. Which term describes the maximum effect a drug can produce regardless of
dose?
A. Potency
B. Efficacy
C. Half-life
D. Bioavailability
, Efficacy is the drug’s maximal therapeutic effect.
Q8. Which pharmacologic principle explains the time required for plasma drug
concentration to reduce by half?
A. Bioavailability
B. Half-life
C. Potency
D. Efficacy
Half-life determines dosing intervals.
Q9. Which drug administration route is most affected by first-pass metabolism in
the liver?
A. IV
B. Oral
C. Sublingual
D. Rectal
Oral drugs undergo first-pass metabolism before systemic circulation.
Q10. Which receptor type responds to acetylcholine in the parasympathetic
nervous system?
