boards.
Unit 1: Introduction to Pharmacology & Drug
Therapy
Question 1
The nurse is reviewing the properties of an ideal
drug. Which property is considered the most
important asset a drug can possess?
A) Chemical stability
B) Low cost
C) Effectiveness
D) Reversibility
Answer: C
Rationale: Effectiveness is the most
important property a drug can possess. If a
drug does not do what it is intended to do,
, there is no justification for administering it,
regardless of how safe, cheap, or stable it
might be.
Question 2
A drug that is highly selective is expected to produce
which clinical benefit?
A) A rapid onset of action
B) Minimal drug-drug interactions
C) Fewer side effects
D) An prolonged therapeutic window
Answer: C
Rationale: A selective drug elicits only the
response for which it is given. Because it
does not interact with unintended receptor
sites, it produces fewer side effects and
adverse reactions.
Question 3
During which stage of new drug development are
clinical trials conducted on healthy volunteers to
assess pharmacokinetics and biological effects?
A) Phase I
B) Phase II
,C) Phase III
D) Phase IV
Answer: A
Rationale: Phase I clinical testing is
conducted on healthy volunteers (or
sometimes patients with the target disease if
the drug is highly toxic) to evaluate drug
metabolism, pharmacokinetics, and safety.
Phase II and III test therapeutic utility and
dosage ranges on actual patients.
Question 4
When analyzing a drug's proprietary or brand name,
the nurse knows that this name is created by which
entity?
A) The United States Adopted Names Council
B) The pharmaceutical marketing company
C) The Food and Drug Administration (FDA)
D) The World Health Organization (WHO)
Answer: B
Rationale: The brand or trade name is the
proprietary name created by the
pharmaceutical company marketing the
drug. The generic name, which is more
, useful for clinical practice, is assigned by the
United States Adopted Names Council.
Unit 2: Basic Principles of Pharmacokinetics
Question 5
A patient is receiving an enteric-coated medication.
The nurse understands that this formulation
prevents the drug from dissolving in which location?
A) The stomach
B) The duodenum
C) The jejunum
D) The colon
Answer: A
Rationale: Enteric-coated preparations are
designed to pass through the stomach intact
and dissolve entirely in the alkaline
environment of the small intestine,
protecting the stomach lining from irritation
and preventing gastric acid from destroying
the drug.
Question 6
Which pharmacokinetic process is most heavily
