Question 1
A nurse is teaching a patient who is starting a new medication.
The patient asks why the dose must be taken exactly as
,prescribed. Which explanation best reflects a basic principle of
pharmacology?
A. Medication doses are chosen to maintain a balance between
therapeutic effects and harmful effects
B. Higher doses always produce faster healing without
increasing risk
C. All medications have identical effects when given at the same
dose
D. Medication effects depend only on the color and form of the
tablet
Correct Answer: A
Rationale:
A medication dose is selected to achieve therapeutic benefits
while minimizing adverse effects. Pharmacology recognizes that
every medication has a therapeutic range where desired effects
occur and toxicity risk increases outside that range. Higher
doses do not always improve outcomes and may cause harm.
Question 2
A nurse reviews a medication order and identifies the name,
dose, route, and frequency. Which principle of safe medication
administration is the nurse applying?
A. Pharmacokinetic adaptation
,B. Medication rights and safety checks
C. Placebo response evaluation
D. Drug tolerance prevention
Correct Answer: B
Rationale:
Verifying medication information and applying medication
administration safety principles helps prevent errors. Nurses
use structured checks, including patient identification and
medication verification, to promote safe therapy.
Question 3
A patient asks why one medication works well for them but
causes a side effect in another person. Which concept best
explains this difference?
A. Individual variation in drug response
B. Universal drug action
C. Complete drug elimination
D. Fixed therapeutic response
Correct Answer: A
Rationale:
Patients may respond differently to medications because of
factors such as age, genetics, health conditions, metabolism,
, and interactions with other medications. Individual variation is
a major consideration in pharmacology.
Question 4
A nurse administers a medication and monitors the patient’s
response over several hours. Which nursing action
demonstrates evaluation of therapeutic effectiveness?
A. Checking whether the medication produces the intended
clinical outcome
B. Recording only the medication name in the chart
C. Assuming the medication works because it was prescribed
D. Avoiding patient assessment after administration
Correct Answer: A
Rationale:
Evaluating medication effectiveness requires assessing whether
the desired therapeutic outcome occurs. Nurses monitor
patient responses to determine if treatment goals are achieved.
Question 5
A medication is described as having a high therapeutic index.
What does this indicate?
A. The medication has a relatively wide margin between
effective and toxic doses
