New Full Exam Questions and Answers ( Included ) 100% Correct
- Pharmacokinetics
Answer: study of how medications enter the body, reach their site of action,
metabolize, and exit the body.Use when timing medication administration, selecting the route of administration, considering pt's risk for alterations in medication action, & evaluating pt's response.
- transport system
Answer: carriers that can move drugs from one side of the cell membrane to the
other side. These are all selective.
- Ions
Answer: these are defined as molecules that have a net electrical charge either
positive or negative that are unable to cross membranes; therefore they must become nonionized to cross from one side to the other.
- Absorption
Answer: this is defined as the movement of a drug from its site of administration into the systemic circulation. The rate will determine how soon effects will begin.
- Distribution
Answer: this is defined as the movement of drugs from the systemic circulation to the site of drug action. This happens in three ways, blood flow to tissues, the ability of a drug to exit the vascular system, and to a lesser extent, the ability of a drug to enter cells.

- Prodrug
Answer: this is a compound that is pharmacologically inactive as administered and then undergoes conversion to its active form through metabolism.
- enterohepatic recirculation
Answer: this is a repeating cycle in which a drug is trans- ported from the liver into the duodenum (through the bile duct) and then back to the liver (through the portal blood)
- minimum effective concentration
Answer: this is defined as the plasma drug level less than which therapeutic effects will not occur.
- maximal efficacy
Answer: this is defined as the largest effect that a drug can produce. This is indicated by the height of the dose-response curve.
- Potency
Answer: this refers to the amount of a drug we must give to elicit an effect. The more of this, allows for smaller doses, but does not mean that smaller doses has better maximal efficacy.
- single occupancy theory
Answer: The intensity of the body's response to the drug is directly related to the number of receptors occupied by the drug.The maximum response occurs when all of the receptors have drug molecules attached.
