BIOL 351 Module 1: Problem Set Practice Questions and
Answers | Latest Update | Graded A+
1. If a patient requires immediate relief from a severe allergic reaction, which
factor related to the onset of action should be considered when choosing a
medication?
The method of drug administration.
The cost of the medication.
The number of doses required per day.
The speed at which the medication takes effect after administration.
2. What is the second step in the absorption process of a drug administered
enterally?
The drug is excreted through the kidneys.
The drug is broken down in the stomach.
The drug passes through the intestinal wall into the bloodstream.
The drug is metabolized by the liver.
3. What is the definition of drug distribution in pharmacology?
The movement of drugs from the circulation to body tissues.
The metabolism of drugs in the liver.
The movement of drugs from tissues to the bloodstream.
4. What is the definition of metabolism in the context of pharmacology?
The absorption of drugs into the bloodstream.
The elimination of drugs from the body.
, The process by which the body chemically alters drugs.
The distribution of drugs throughout the body.
5. Describe the relationship between drug administration and the process of
dissolution in pharmacology.
Drug administration is solely about the injection of drugs into the
bloodstream.
Dissolution occurs only after the drug has been absorbed into the
bloodstream.
Drug administration does not involve any chemical processes.
Drug administration involves delivering a dosage form that must
dissolve before the drug can be absorbed into the body.
6. What is a noncompetitive antagonist in pharmacology?
A noncompetitive antagonist enhances the effect of an agonist by
binding to the same site on the receptor.
A noncompetitive antagonist is a substance that reduces the effect
of an agonist by binding to a different site on the receptor.
A noncompetitive antagonist is a substance that increases the
metabolism of a drug.
A noncompetitive antagonist is a type of agonist that activates
receptors.
7. What is the designation for the safest drug category during pregnancy
according to the FDA?
Category B
Category A
, Category C
Category D
8. Pharmacokinetics is the study of how medications:
Enter the body, reach their site of action, are metabolized, and exit
the body
Are manufactured and distributed to pharmaceutical companies
Are derived from plants
Are used for certain disease processes
9. In a clinical scenario, if a patient is administered a drug that acts as an agonist
for a specific receptor, what would you expect to observe?
An increase in the physiological response associated with that
receptor.
No change in the physiological response associated with that
receptor.
An adverse reaction unrelated to the receptor's function.
A decrease in the physiological response associated with that
receptor.
10. Describe how a noncompetitive antagonist affects the action of an agonist at
a receptor.
A noncompetitive antagonist binds to a different site on the
receptor, preventing the agonist from eliciting its full effect,
regardless of the agonist concentration.
A noncompetitive antagonist binds to the same site as the agonist,
blocking its action.
, A noncompetitive antagonist enhances the binding of the agonist to
the receptor.
A noncompetitive antagonist has no effect on the receptor's activity.
11. What is the primary form of drug administration represented by a tablet?
Topical administration
Oral administration
Intravenous administration
Inhalation administration
12. Drug distribution is defined as
Transfer of drug from systemic circulation to kidney
Transfer of drug from site of absorption to systemic circulation
All the above
Transfer of drug from systemic circulation to tissues
13. What is the definition of an agonist in pharmacology?
An agonist is a substance that blocks a receptor's activity.
An agonist is a substance that enhances the metabolism of drugs.
An agonist is a type of drug that has no effect on receptors.
An agonist is a substance that activates a receptor to produce a
biological response.
14. Following are some drug release patterns of different types of tablets of the
same drug. Find out the one that has delayed release feature.
