,Question 1
A nurse is caring for a client who is considering enrollment in a
clinical trial for an investigational medication. Which statement
by the nurse best describes the primary purpose of informed
consent?
A. It guarantees the investigational drug will be more effective
than current therapy.
B. It ensures the participant understands the study, its potential
risks and benefits, and voluntarily agrees to participate.
C. It allows researchers to administer the study drug without
further explanation.
D. It prevents the participant from withdrawing from the study
after enrollment.
Correct Answer: B
Rationale:
Informed consent is an ethical and legal process that ensures
potential participants receive understandable information
about the study's purpose, procedures, potential benefits, risks,
alternatives, and their right to refuse or withdraw at any time
without penalty. Option A is incorrect because research studies
do not guarantee effectiveness. Option C is incorrect because
informed consent is an ongoing process, not a one-time
,authorization. Option D is incorrect because participants may
withdraw from most clinical trials at any time.
Question 2
A nurse is reviewing the difference between pharmacokinetics
and pharmacodynamics with a group of nursing students.
Which statement accurately describes pharmacokinetics?
A. It examines how drugs produce therapeutic and adverse
effects at receptor sites.
B. It focuses on how the body absorbs, distributes, metabolizes,
and eliminates medications.
C. It identifies the genetic variations affecting medication
response.
D. It measures patient adherence to prescribed drug therapy.
Correct Answer: B
Rationale:
Pharmacokinetics describes what the body does to a drug
through absorption, distribution, metabolism, and excretion.
Option A describes pharmacodynamics, which explains the
drug's effects on the body. Option C refers to
pharmacogenomics. Option D relates to medication adherence
rather than pharmacokinetics.
Question 3
, A client asks why a newly prescribed medication is referred to
by both a generic name and a brand name. Which response by
the nurse is most accurate?
A. The generic name is assigned after the patent expires.
B. The brand name identifies the active ingredient, while the
generic name identifies the manufacturer.
C. The generic name is the standardized nonproprietary name,
whereas the brand name is chosen by the manufacturer.
D. The generic and brand names represent different chemical
substances.
Correct Answer: C
Rationale:
The generic name is the standardized, nonproprietary name
assigned to the active drug, while the manufacturer selects the
brand (trade) name. Option A is incorrect because the generic
name exists before patent expiration. Option B reverses the
definitions. Option D is incorrect because generic and brand
products contain the same active ingredient, although inactive
ingredients may differ.
