Exam Questions With Verified Correct Answers And
Explanations| Nightingale College | Graded A+
Question 1
The primary goal of pharmacology is to study:
A. How drugs interact with living organisms
B. How diseases are diagnosed only
C. How surgical procedures are performed
D. How medical devices are manufactured
Correct Answer: A. How drugs interact with living organisms
Explanation:
Pharmacology is the study of medications, including their actions, effects,
mechanisms, therapeutic uses, adverse effects, and interactions within the
body.
Question 2
Pharmacokinetics refers to:
A. What the body does to the drug
B. What the drug does to the body
C. The psychological effects of medication
D. The cost of medications
Correct Answer: A. What the body does to the drug
Explanation:
Pharmacokinetics describes drug movement through the body, including
absorption, distribution, metabolism, and excretion (ADME).
Question 3
1
,Pharmacodynamics refers to:
A. What the drug does to the body
B. How the kidney removes medication
C. How drugs are absorbed
D. How drugs are stored
Correct Answer: A. What the drug does to the body
Explanation:
Pharmacodynamics involves drug effects, mechanisms of action, receptor
interactions, and dose-response relationships.
Question 4
The process by which a drug enters the bloodstream is called:
A. Absorption
B. Distribution
C. Metabolism
D. Excretion
Correct Answer: A. Absorption
Explanation:
Absorption is the movement of medication from its administration site into
systemic circulation.
Question 5
The primary organ responsible for drug metabolism is:
A. Liver
B. Heart
C. Skin
D. Spleen
2
,Correct Answer: A. Liver
Explanation:
The liver contains enzymes, especially cytochrome P450 enzymes, that
metabolize many medications.
Question 6
The primary organ responsible for drug excretion is:
A. Kidney
B. Lung
C. Pancreas
D. Thyroid gland
Correct Answer: A. Kidney
Explanation:
The kidneys remove many drugs and their metabolites through urine
formation.
Question 7
A drug’s half-life refers to:
A. The time required for drug concentration to decrease by half
B. The time needed for absorption to begin
C. The maximum drug dose allowed
D. The time needed for drug administration
Correct Answer: A. The time required for drug concentration to decrease
by half
Explanation:
Half-life helps determine dosing intervals and how long a medication remains
active in the body.
3
, Question 8
A medication that produces a response by binding to a receptor is called:
A. Agonist
B. Antagonist
C. Inhibitor only
D. Catalyst
Correct Answer: A. Agonist
Explanation:
An agonist activates receptors to produce a physiological response.
Question 9
A medication that blocks receptor activation is called:
A. Antagonist
B. Agonist
C. Enzyme activator
D. Metabolite
Correct Answer: A. Antagonist
Explanation:
Antagonists bind to receptors but prevent activation, blocking the effects of
agonists.
Question 10
The nurse should identify an adverse drug reaction as:
A. An unintended harmful response to a medication
B. The expected therapeutic effect
C. A normal nutritional response
D. A placebo effect
