delivered through the body.
Absorption Ans: It is the movement of a drug from its site of
Guru01 - Stuvia
administration to the bloodstream.
Expert
Metabolism Ans: Biochemically alters a drug to make it
usable in the body.
Excretion Ans: The elimination of a drug and any of its
metabolites.
Empiric therapy Ans: Based on clinical probabilities and
involves administering drugs when a certain pathological
condition is likely based on the client's initial symptoms.
Maintenance therapy Ans: It does not eliminate existing
problems, but it prevents the progression of a disease (such as
hypertension) or condition.
Supplemental therapy Ans: Provides the body with the
necessary substances (like vitamins or hormones) to maintain
normal function.
Prophylactic therapy Ans: Prevents illness or other
undesirable outcomes during planned events such as surgery.
, 2
Acute Therapy Ans: Essential for sustaining life or treating
disease.
Palliative Therapy Ans: Focuses on making clients as
comfortable as possible by relieving symptoms, pain, and
stress from serious illness. The goal is to improve the quality
of life.
Supportive Therapy Ans: Maintains body function integrity
(such as blood transfusion) while the client recovers from
illness or trauma.

trade name Ans: The proprietary name for a medication used
Guru01 - Stuvia
for marketing.
Expert
Generic names Ans: The nonproprietary name of the
medication identifies the drug within a class.
Chemical names Ans: The name describes the molecular
structure of a drug.
Pharmacokinetics Ans: The study of what happens to a drug
once it enters the body.
Bioavailability Ans: Refers to the degree and rate at which a
drug is absorbed into the bloodstream.
first-pass effect Ans: Decreases the drug's bioavailability to
less than 100%.
cytochrome P-450 enzymes Ans: Hepatic metabolism
involves enzymes known as? These enzymes regulate the
reactions that facilitate drug metabolism.
, 3
Half-life Ans: The time required for one-half (50%) of the drug
to be removed from the body.
five Ans: After about ________ half-lives, most drugs are
eliminated from the body.
steady state Ans: It is when the amount of the drug
eliminated and the amount of the drug absorbed are equal,
which is 4-5 half-lives.

onset of action Ans: The time required to elicit a therapeutic
response.
Guru01 - Stuvia
peak effect Ans: The time required to reach its maximum
Expert
therapeutic response.
duration of action Ans: The time at which the drug
concentration is sufficient (without more doses) to elicit a
therapeutic response.
Aging Effects on Absorption Ans: > decreased gastric pH
> slowed gastric emptying
> slowed movement through the entire gastrointestinal (GI)
tract
> decreased blood flow to the GI tract 40-50%
Aging Effects on Distribution Ans: > decreased percentage of
total body water
> increased fat content as lean body mass decreases
