,Question 1
A nurse is participating in a clinical research study evaluating a
new medication. Which statement best describes the primary
purpose of obtaining informed consent from study participants?
A. To guarantee that participants will benefit from the
investigational drug
B. To ensure participants understand the study, its potential
risks, benefits, and alternatives before voluntarily agreeing
C. To protect researchers from legal liability if adverse events
occur
D. To allow investigators to withhold information that could
influence participation
Correct Answer: B
Rationale:
Informed consent ensures participants receive understandable
information regarding the purpose of the study, expected
procedures, potential risks, possible benefits, alternatives, and
the voluntary nature of participation before enrollment. It does
not guarantee benefit (A), eliminate investigator responsibility
(C), or permit withholding relevant information (D).
Question 2
,A patient asks why medications must undergo extensive testing
before becoming available to the public. Which response by the
nurse is most appropriate?
A. "Testing mainly determines whether the drug is less
expensive than existing therapies."
B. "Testing helps evaluate the medication's safety, effectiveness,
appropriate dosing, and potential adverse effects."
C. "Testing guarantees the medication will never cause serious
adverse reactions."
D. "Testing is only required for injectable medications."
Correct Answer: B
Rationale:
Drug development evaluates safety, efficacy, dosing,
pharmacokinetics, adverse effects, and appropriate patient
populations before approval. Clinical testing cannot eliminate all
risks (C), is not performed to compare cost (A), and applies to
medications regardless of dosage form (D).
Question 3
A nurse is reviewing a medication order for an older adult with
impaired kidney function. Which pharmacokinetic process is
most likely to require dosage adjustment?
A. Drug color
, B. Drug elimination
C. Drug packaging
D. Drug taste
Correct Answer: B
Rationale:
Renal impairment commonly decreases drug elimination,
increasing the risk for drug accumulation and toxicity. Dosage
reductions or extended dosing intervals may be necessary. Drug
color (A), packaging (C), and taste (D) do not influence
pharmacokinetics.
Question 4
A patient asks why two people taking the same medication may
experience different responses. Which explanation by the nurse
is most accurate?
A. Every individual responds identically to medications.
B. Individual responses may differ because of age, genetics,
organ function, disease states, and interactions with other
medications.
C. Drug effects depend only on body weight.
D. Medications work the same regardless of concurrent
illnesses.
