Quiz 3

1.

Which of the following best describes the role of a pharmacological drug?

A. Provides nutrients to support growth B. Alters physiological processes to prevent, treat, or diagnose disease C. Only treats existing illnesses D. Any chemical substance found in nature

Please select an answer

Tip: Drugs act on the body to influence function or health; prevention, treatment, and diagnosis are all included.

2.

A drug derived from plant tissues is an example of:

A. Synthetic drug B. Mineral-based drug C. Natural product D. Recombinant protein

Please select an answer

Tip: Many drugs (e.g., morphine, digoxin) are directly extracted from plants and classified as natural products.

3.

Pharmacokinetics is concerned with:

A. The mechanism of action of drugs at the cellular level B. The movement and transformation of drugs within the body C. Testing whether a drug is toxic in animals D. The cost-effectiveness of drug therapy

Please select an answer

Tip: Pharmacokinetics tracks what the body does to the drug—ADME (Absorption, Distribution, Metabolism, Excretion).

4.

Which sequence accurately represents the pharmacokinetic process?

A. Absorption → Distribution → Metabolism → Excretion B. Distribution → Absorption → Metabolism → Excretion C. Metabolism → Absorption → Distribution → Excretion D. Excretion → Metabolism → Absorption → Distribution

Please select an answer

Tip: Drugs are absorbed, distributed to tissues, metabolized (often in the liver), and then excreted.

5.

Therapeutic pharmacology primarily focuses on:

A. Preventing the onset of disease B. Relieving symptoms and restoring normal physiological function C. Evaluating genetic variation in drug response D. Investigating natural drug sources

Please select an answer

Tip: The main goal is to treat illness and improve health, not to prevent it.

6.

Preventative pharmacology is best exemplified by:

A. Vaccines administered before exposure to a disease B. Analgesics given for existing pain C. Antibiotics used only after an infection occurs D. Sedatives for anesthesia

Please select an answer

Tip: Preventative drugs reduce disease incidence before it manifests.

7.

Pharmacogenetics helps explain why:

A. All animals respond the same way to a drug B. Some individuals have unusual responses or side effects C. Drugs are metabolized the same in every tissue D. Generic names replace brand names

Please select an answer

Tip: Genetic differences influence metabolism, efficacy, and risk of adverse effects.

8.

In laboratory animal studies, ethical administration of drugs requires:

A. Following protocols that minimize pain, distress, and unnecessary use B. Administering maximum doses to ensure observable effect C. Avoiding regulated guidelines to save time D. Using only synthetic drugs to control variables

Please select an answer

Tip: Ethics in animal pharmacology centers on minimizing harm and complying with legal standards (3Rs: Replacement, Reduction, Refinement).

9.

Morphine is classified as a:

A. Plant-derived alkaloid B. Mineral-based drug C. Microbial metabolite D. Synthetic peptide

Please select an answer

Tip: Morphine is an alkaloid extracted from the opium poppy (Papaver somniferum).

10.

The primary purpose of standardized drug nomenclature is:

A. To ensure that each drug is universally identifiable and unambiguous B. To obscure the chemical structure from the public C. To promote the use of brand names in clinical practice D. To classify drugs solely by their source

Please select an answer

Tip: Generic or standardized names prevent confusion between brand names or countries.
