Q1 QUESTION 1 OF 90
Bioavailability
RESPONSE
the rate at and the extent to which a nutrient is absorbed and used
RATIONALE
Bioavailability refers to how efficiently a substance enters systemic circulation and becomes
available for physiological action. This encompasses both the speed of absorption and the total
amount absorbed, directly impacting therapeutic efficacy. Therefore, it is defined by the rate and
extent of absorption and utilization.
Q2 QUESTION 2 OF 90
Absorption
RESPONSE
movement of a drug from its site of administration into the bloodstream for distribution to the
tissues
RATIONALE
Absorption describes the pharmacokinetic process by which a drug transitions from its
administration site into systemic circulation. This initial step is critical for the drug to reach target
tissues and exert its therapeutic or adverse effects. Subsequent distribution, metabolism, and
excretion follow this foundational phase.
Q3 QUESTION 3 OF 90
Distribution
RESPONSE
transport of a drug by the bloodstream to its site of action
Page 2
, RATIONALE
Distribution describes how a pharmacologic agent moves throughout the body after
administration. This phase specifically involves the circulation of the drug via the bloodstream to
reach its intended target site for therapeutic effect. It is a key pharmacokinetic process influencing
drug efficacy.
Q4 QUESTION 4 OF 90
Another word for metabolism?
RESPONSE
biotransformation
RATIONALE
Biotransformation is the chemical alteration of a drug within the body, which is synonymous with
drug metabolism. This process, primarily occurring in the liver, converts lipophilic drugs into more
water-soluble metabolites for excretion. It is a fundamental concept in pharmacology and nursing
assessment of drug action.
Q5 QUESTION 5 OF 90
Where does biotransformation occur?
RESPONSE
Mainly occurs in the liver
RATIONALE
Biotransformation, or drug metabolism, primarily involves enzymatic alteration of xenobiotics. The
hepatic microsomal enzyme system, particularly cytochrome P450, is the major site for these
chemical modifications. Therefore, the liver is the principal organ responsible for drug
biotransformation.
Q6 QUESTION 6 OF 90
Biotransformation (metabolism)
Page 3
, RESPONSE
- One or more biochemical reactions involving a parent drug
RATIONALE
Biotransformation refers to the body's process of chemically altering drugs. This typically involves
enzymatic modifications to make the parent drug more water-soluble for excretion. These
reactions are essential for drug clearance and can also activate or inactivate drug metabolites.
Q7 QUESTION 7 OF 90
What does biotransformation produce?
RESPONSE
- metabolite that can be inactive or active
RATIONALE
Biotransformation, or drug metabolism, modifies a drug's chemical structure within the body,
primarily in the liver. This process yields metabolites, which are chemically altered forms of the
original drug that may exhibit reduced, enhanced, or even a novel pharmacological activity
compared to the parent compound.
Q8 QUESTION 8 OF 90
Excretion
RESPONSE
elimination of drugs from the body
RATIONALE
Drug excretion is the final phase of pharmacokinetics, involving the removal of active drugs or their
metabolites from the body. This process is critical for preventing drug accumulation and toxicity,
primarily occurring via the kidneys but also through other routes like bile and sweat.
