1. Which of the following routes of administration has the fastest
absorption rate?
A. Oral
B. Subcutaneous
C. Intramuscular
D. Intravenous
CORRECT ANSWER: D. Intravenous
Rationale: Intravenous administration delivers the drug directly
into the bloodstream, bypassing absorption barriers and providing
immediate therapeutic effect. Oral administration requires GI
absorption, while subcutaneous and intramuscular routes require
,absorption through capillary walls before entering systemic
circulation.
2. The nurse knows that the primary organ responsible for drug
metabolism is the:
A. Kidney
B. Lungs
C. Liver
D. Pancreas
CORRECT ANSWER: C. Liver
Rationale: The liver contains the cytochrome P450 enzyme
system, which metabolizes most drugs through Phase I (oxidation,
reduction, hydrolysis) and Phase II (conjugation) reactions. This
biotransformation converts lipid-soluble drugs into more water-
soluble metabolites for renal excretion.
3. Which of the following best describes a drug's half-life?
A. The time it takes for the drug to reach peak effect
B. The time it takes for the drug to be fully absorbed
,C. The time it takes for the plasma concentration to decrease by 50%
D. The time it takes for the drug to be completely excreted
CORRECT ANSWER: C. The time it takes for the plasma
concentration to decrease by 50%
Rationale: Half-life (t½) is the time required for the plasma
concentration of a drug to be reduced by 50%. It is a crucial
pharmacokinetic parameter used to determine dosing intervals and
the time required to reach steady-state concentration.
Approximately 4-5 half-lives are needed to reach steady state and
to eliminate 95% of a drug from the body.
4. The nurse understands that pharmacotherapeutics is defined as:
A. The study of how drugs are absorbed, distributed, metabolized,
and excreted
B. The use of drugs to prevent, treat, and diagnose disease
C. The study of the toxic effects of drugs
D. The process of drug development and approval
CORRECT ANSWER: B. The use of drugs to prevent, treat, and
diagnose disease
, Rationale: Pharmacotherapeutics is the branch of pharmacology
that focuses on the clinical application of drugs for the prevention,
treatment, and diagnosis of disease. It encompasses drug selection,
dosing, monitoring, and patient education. Pharmacokinetics (A)
refers to ADME, while toxicology (C) is the study of adverse
effects.
5. 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. Metabolism
Rationale: Metabolism (biotransformation) is the enzymatic
conversion of a drug into metabolites, primarily occurring in the
liver. This process converts lipid-soluble drugs into water-soluble
compounds to facilitate renal excretion. The primary metabolic
pathways are Phase I (cytochrome P450) and Phase II
(conjugation) reactions.
