3. What two factors can affect the distribution of a drug?

Blood perfusion of the target tissue and the characteristics of the drug itself.

The patient's age and gender.

The color of the drug and its taste.

The location of the hospital where the drug is administered.

The distribution of a drug is primarily influenced by factors such as blood perfusion of the target tissue and the specific characteristics of the drug itself. Factors like color, taste, patient demographics, or hospital location do not directly impact the distribution of a drug within the body.

Explanation

Submit

4. What is antagonism?

To encourage

To pursue

To prevent.

To facilitate

Antagonism refers to actively opposing or preventing something, rather than encouraging, pursuing, or facilitating it.

Explanation

Antagonism refers to actively opposing or preventing something, rather than encouraging, pursuing, or facilitating it.

Submit

5. What is the meaning of biotransformation?

The transformation of organic matter into soil nutrients.

A method used for weather forecasting in biological systems.

The process of converting biological waste into energy.

Modification of a drug by living organisms.

Biotransformation specifically refers to the modification of a drug by living organisms, typically in the liver, to help the body metabolize and eliminate the drug.

Explanation

Biotransformation specifically refers to the modification of a drug by living organisms, typically in the liver, to help the body metabolize and eliminate the drug.

Submit

6. How are drugs excreted from the body?

Through sweat

Through breathing

Unchanged or modified.

Through tears

Drugs can be excreted from the body either unchanged or after being modified by metabolic processes.

Explanation

Drugs can be excreted from the body either unchanged or after being modified by metabolic processes.

Submit

7. Where are most drugs metabolized?

In the kidneys

In the lungs

In the liver.

In the stomach

The liver is primarily responsible for metabolizing drugs due to its high concentration of enzymes that break down substances. This process helps in eliminating drugs from the body.

Explanation

The liver is primarily responsible for metabolizing drugs due to its high concentration of enzymes that break down substances. This process helps in eliminating drugs from the body.

Submit

8. Through what two organs are most drugs excreted?

Through the skin or the lungs.

Through the liver or the spleen.

Through the kidneys or the digestive tract.

Through the bladder or the pancreas.

Most drugs are excreted from the body through either the kidneys or the digestive tract. While some drugs may be excreted through other organs like the skin or lungs, the primary routes are through the kidneys or digestive tract.

Explanation

Submit

9. What can biotransformation lead to?

Active drug metabolites that are more potent than the original drug

Unchanged drug molecules that remain in the body

Toxins that can harm the body

Inactive drug metabolites or, in some situations, to drug metabolites that have specific effects on the body.

Biotransformation can lead to various outcomes, including the production of inactive drug metabolites or metabolites with specific effects on the body. The incorrect answers misrepresent the possible results of biotransformation.

Explanation

Submit

10. What is the meaning of pharmacodynamics?

The study of agricultural farming techniques.

The practice of traditional medicine.

A form of physical therapy.

The resulting action of drugs on living beings.

Pharmacodynamics refers to the study of the action of drugs on living organisms, including the resulting effects and mechanisms of action.

Explanation

Pharmacodynamics refers to the study of the action of drugs on living organisms, including the resulting effects and mechanisms of action.

Submit

11. What is the meaning of pharmacokinetics?

The motion of drugs in a body.

The study of drug manufacturing processes.

The study of drug side effects.

The study of drug interactions with food.

Pharmacokinetics specifically relates to how a drug moves through the body, including absorption, distribution, metabolism, and excretion.

Explanation

Pharmacokinetics specifically relates to how a drug moves through the body, including absorption, distribution, metabolism, and excretion.

Submit

12. What are the processes involved in the motion or movement of drugs?

Absorption, distribution, metabolism and excretion. ADME

Activation, transmission, reaction, elimination

Ingestion, assimilation, retention, elimination

Preparation, administration, utilization, elimination

The correct processes involved in the motion or movement of drugs are absorption, distribution, metabolism, and excretion (ADME).

Explanation

The correct processes involved in the motion or movement of drugs are absorption, distribution, metabolism, and excretion (ADME).

Submit

13. What term is used to refer to the difference between a safe and therapeutic dose of a drug and its toxic dose?

Safety margin

Toxicity ratio

Dose differential

Therapeutic index.

The therapeutic index of a drug is a measure of its safety. It is calculated by dividing the dose that produces toxicity by the dose that produces a clinically desired or effective response. A higher therapeutic index indicates that the drug is safer to use.

Explanation

Submit

14. What is the meaning of the term Half-life?

A mathematical term describing the division of an object into two equal parts.

The period it takes for a person to change their lifestyle habits by half.

The length of time needed for a drug to decrease in its active form within the body by half.

The duration of time for a radioactive substance to lose half of its radiation.

The correct definition of Half-life specifically refers to the time it takes for a drug to decrease in its active form by half within the body.

Explanation

The correct definition of Half-life specifically refers to the time it takes for a drug to decrease in its active form by half within the body.

Submit

15. What is meant by drug regimen?

A strict diet plan to avoid medication.

A list of illegal drugs one is addicted to.

The process of manufacturing pharmaceutical drugs.

The proper drug usage to achieve an anticipated outcome.

A drug regimen refers to the prescribed plan and proper use of medication to achieve a specific outcome, focusing on dosage, timing, and duration of treatment.
