1. The nurse knows that the study of how drugs move through the
body is called:
A. Pharmacodynamics
B. Pharmacokinetics
C. Pharmacogenomics
D. Pharmacotherapeutics
CORRECT ANSWER: B
,Rationale: Pharmacokinetics involves the absorption, distribution,
metabolism, and excretion (ADME) of drugs. Pharmacodynamics,
on the other hand, is the study of how drugs affect the body at
receptor sites.
2. The process by which a drug is broken down into inactive forms is
known as:
A. Absorption
B. Distribution
C. Metabolism
D. Excretion
CORRECT ANSWER: C
Rationale: Metabolism is the biotransformation of a drug into
metabolites, often occurring in the liver. This process converts lipid-
soluble drugs into water-soluble forms for easier excretion by the
kidneys.
3. The primary site of drug excretion is the:
A. Liver
B. Lungs
,C. Kidneys
D. Skin
CORRECT ANSWER: C
Rationale: Most drugs are excreted through the kidneys via urine.
The liver also plays a role in drug elimination through bile, but the
kidneys are the primary route of excretion for most medications.
4. The nurse recognizes that the half-life of a drug refers to:
A. The total duration of drug effect
B. The time required for 50% of the drug to be eliminated
C. The onset of drug action
D. The peak plasma concentration
CORRECT ANSWER: B
Rationale: Half-life measures how long it takes for half of a drug
dose to be eliminated from the body. This determines dosing
intervals and time to reach steady state.
5. Which of the following routes has the fastest absorption rate?
, A. Oral
B. Subcutaneous
C. Intravenous
D. Intramuscular
CORRECT ANSWER: C
Rationale: Intravenous administration delivers the drug directly into
the bloodstream, providing immediate absorption and 100%
bioavailability. No absorption phase is required.
6. Bioavailability is defined as:
A. The time to reach peak plasma concentration
B. The fraction of an administered dose that reaches systemic
circulation unchanged
C. The total amount of drug excreted in urine
D. The degree of protein binding
CORRECT ANSWER: B
Rationale: Bioavailability is the percentage or fraction of the
administered drug that successfully reaches the systemic circulation.
IV administration provides 100% bioavailability.
