NUR 210/ NUR210 (Latest 2024/ 2025) Principles
of Pharmacology Exam | Questions and Verified
Answers| Grade A| Galen
1. Which organ is primarily responsible for metabolizing most medications?
A) Kidney
B) Liver
C) Stomach
D) Pancreas
B) Liver
The liver contains enzymes that chemically alter drugs through metabolism,
making them easier to excrete.
2. What is the therapeutic effect of a medication?
A) The side effects produced by the drug
B) The intended beneficial outcome of the drug
C) The toxic reaction caused by overdose
D) The interaction between two drugs
B) The intended beneficial outcome of the drug
The therapeutic effect is the desired clinical outcome for which the medication is
prescribed.
3. A drug with a narrow therapeutic index requires:
A) No monitoring after administration
, B) Careful monitoring of blood levels
C) A high dose to be effective
D) Less frequent dosing
B) Careful monitoring of blood levels
Narrow therapeutic index drugs have a small margin between therapeutic and
toxic doses, so monitoring is essential.
4. Which route of administration provides the fastest onset of action?
A) Oral
B) Subcutaneous
C) Intravenous
D) Intramuscular
C) Intravenous
IV administration delivers medication directly into the bloodstream for
immediate effect.
5. What does "half-life" of a drug refer to?
A) The time it takes for half of the drug dose to be eliminated from the
body
B) The time for the drug to reach peak plasma concentration
C) The duration of the drug’s therapeutic effect
D) The time required for the drug to be absorbed
A) The time it takes for half of the drug dose to be eliminated from the body
Half-life helps determine dosing intervals and duration of drug action.
6. Which of the following is an example of a Schedule II controlled substance?
A) Acetaminophen
, B) Morphine
C) Diazepam
D) Ibuprofen
B) Morphine
Morphine is a Schedule II drug due to its high potential for abuse but accepted
medical use.
7. What is the primary purpose of a drug’s “black box warning”?
A) To indicate the drug is safe for all patients
B) To highlight serious or life-threatening risks
C) To warn about mild side effects
D) To identify over-the-counter drugs
B) To highlight serious or life-threatening risks
Black box warnings alert clinicians to potentially severe adverse effects.
8. Which phase of pharmacokinetics involves the movement of a drug from
the bloodstream into the tissues?
A) Absorption
B) Distribution
C) Metabolism
D) Excretion
B) Distribution
Distribution describes how the drug spreads to various tissues after absorption.
9. A patient is prescribed a medication that is highly protein-bound. What
implication does this have?
A) The drug will be excreted rapidly
, B) There is less free active drug available
C) It will not cross the blood-brain barrier
D) It has no clinical significance
B) There is less free active drug available
Only unbound drug molecules are pharmacologically active and can cross
membranes.
10.Which drug interaction increases the effect of warfarin, increasing bleeding
risk?
A) Vitamin K
B) Aspirin
C) Rifampin
D) Phenobarbital
B) Aspirin
Aspirin inhibits platelet function and potentiates warfarin’s anticoagulant
effect, increasing bleeding risk.
11.What is the antidote for acetaminophen toxicity?
A) Naloxone
B) Activated charcoal
C) N-acetylcysteine
D) Flumazenil
C) N-acetylcysteine
N-acetylcysteine replenishes glutathione stores to detoxify acetaminophen
metabolites.
