ANSWERS GUARANTEED PASS 2026
• Adbsorption. Answer: Movement of a drug from the outside of the
body into the bloodstream
• Adverse Drug Reaction (ADR) Answer: Same as Adverse Effect
• Adverse Effect Answer: A drug effect that is more severe than
expected and has the potential to damage tissue or cause serious health
problems.
It may also be called a toxic effect or toxicity and usually requires
intervention by the prescriber
• Agonist Answer: An extrinsic drug that activates the receptor site of a
cell and mimics the actions of naturally occurring body substances
(intrinsic drugs)
• Allergic Response Answer: Type of adverse effect in which the
presence of the drug stimulates the release of histamine and other body
chemicals that cause inflammatory reactions.
The response may be as mild as a rash or as severe and life threatening
as anaphylaxis
,• Antagonist Answer: An extrinsic drug that blocks the receptor site of a
cell, preventing the naturally occuring body substance from binding to
the receptor
• Bioavailability Answer: The percentage of a drug dose that actually
reaches the blood
• Black Box Warning Answer: A notice that a drug may produce serious
or even life-threatening effect in some people in addition to its beneficial
effects
• Brand Name Answer: A manufacturer-owned name of generic drug;
Also called "trade name" or "proprietary name"
• Contraindication Answer: A personal or health-related reason for not
administering a specific drug to a patient or a group of patients
• Cytotoxic Answer: Drug action that is intended to kill a cell or an
organism
• Distribution Answer: (Drug Distribution)
The extent that a drug absorbed into the bloodstream spreads into the
three body water compartments
,• Drug Answer: Any small molecule that changes any body function by
working at the chemical and cell levels
• Drug Therapy Answer: The planned use of a drug to prevent or
improve a health problem
• Duration of Action Answer: The length of time a drug is present in the
blood at or above the level needed to prodice an effect or response
• Elimination Answer: The removal of drugs from the body
accomplished by certain body systems
• Enteral Route Answer: Movememnt of drugs from the outside of the
body to the inside using the gastrointestinal tract
• First-Pass Loss Answer: Rapid inactivation or elimination of oral drugs
as a result of liver metabolism
• Generic Name Answer: National and international public drug name
created by the United States Adopted Names (USAN) Council to
indicate the usual use or chemical composition of a drug
• USAN Answer: United States Adopted Names
• Half-Life Answer: Time span needed for one half of a drug dose to be
eliminated
, • High-Alert Drug Answer: A drug that has an increased risk for causing
patient harm if it us used in error
• Intended Action Answer: Desired Effect (main effect) of a drug on a
specific body cells or tissues;
Same as Therapeutic Response
• Loading Dose Answer: The first dose of a drug that is larger than all
subsequent doses of the same drug;
Used when it takes more drug to reach steady state than it does to
maintain it
• Mechanism of Action Answer: Exactly how, at the cellular level, a
drug to reach steady state than it does to maintain it
• Medication Answer: Any small molecule that changes any body
function by working at the chemical and cell levels (same as a drug)
• Metabolism Answer: (Drug Metabolism)
Chemical reaction in the body that changes the chemical shape and
content of a drug, preparing the drug for inactivation and elimination
• Minimum Effective Concentration (MEC) Answer: The smallest
amount of drug necessary in the blood or target tissue to result in a
measurable intended action
