,NU 150 EXAM 1 Pharmacology Galen Questions And Answers
2026/2027 Galen College
Q1. What is pharmacology?
A) The study of drugs and their effects on living organisms
B) The study of human anatomy
C) The preparation of surgical instruments
D) The diagnosis of infectious diseases
Correct Answer: A) The study of drugs and their effects on living organisms
Rationale: Pharmacology examines medications, their actions, effects, uses,
interactions, adverse effects, and the body's response to them.
Q2. Which drug name is standardized and generally remains
consistent regardless of manufacturer?
A) Trade name
B) Generic name
C) Chemical nickname
D) Brand nickname
Correct Answer: B) Generic name
Rationale: The generic name is the standardized nonproprietary name of a
medication, while trade names are assigned by manufacturers.
Q3. What does pharmacokinetics describe?
A) What the drug does to the body
B) What the body does to the drug
C) How nurses document medication errors
D) How drugs are named
Correct Answer: B) What the body does to the drug
Rationale: Pharmacokinetics describes absorption, distribution, metabolism,
and excretion—the processes affecting a drug after it enters the body.
Q4. What does pharmacodynamics describe?
A) The movement of a drug through the body
B) The elimination of a drug through the kidneys
C) The effects of a drug on the body and its mechanism of action
D) The legal classification of a drug
,Correct Answer: C) The effects of a drug on the body and its mechanism of
action
Rationale: Pharmacodynamics focuses on how medications produce effects,
including receptor interactions and physiologic responses.
Q5. Which pharmacokinetic process involves movement of a drug
from the site of administration into systemic circulation?
A) Distribution
B) Absorption
C) Metabolism
D) Excretion
Correct Answer: B) Absorption
Rationale: Absorption is the movement of medication from its
administration site into the bloodstream.
Q6. Which organ is the major site of metabolism for many
medications?
A) Liver
B) Spleen
C) Pancreas
D) Thyroid
Correct Answer: A) Liver
Rationale: The liver contains enzymes that chemically alter many
medications and prepare them for elimination.
Q7. Which organ is primarily responsible for excreting many
medications and their metabolites?
A) Heart
B) Kidneys
C) Lungs
D) Stomach
Correct Answer: B) Kidneys
Rationale: The kidneys eliminate many medications and metabolites
through urine, making renal function important when determining drug
safety and dosing.
Q8. What does a medication's half-life represent?
, A) The amount of medication absorbed
B) The time required for the medication to begin working
C) The time required for the drug concentration to decrease by
approximately 50%
D) The maximum dose that can be given
Correct Answer: C) The time required for the drug concentration to decrease
by approximately 50%
Rationale: Half-life describes the time required for the amount or
concentration of a drug in the body to decline by half.
**Q9. Which patient factor can significantly alter medication response?
A) Age
B) Favorite food
C) Hair color
D) Hand dominance
Correct Answer: A) Age
Rationale: Age can affect absorption, metabolism, distribution, excretion,
and sensitivity to medications, especially in pediatric and older adult
patients.
Q10. Why can renal impairment increase medication toxicity?
A) It may reduce drug excretion and allow medications to accumulate
B) It always increases medication absorption
C) It prevents all drug metabolism
D) It eliminates protein binding
Correct Answer: A) It may reduce drug excretion and allow medications to
accumulate
Rationale: Reduced renal function can slow elimination of drugs or
metabolites, increasing serum concentrations and toxicity risk.
Q11. Which statement best describes an agonist?
A) A drug that blocks receptor activity
B) A drug that activates a receptor to produce a response
C) A drug with no physiologic activity
D) A substance used only as a placebo
Correct Answer: B) A drug that activates a receptor to produce a response
