Question 1
,A nurse is teaching a patient about why medications must be
taken as prescribed. Which statement by the patient indicates
understanding of a basic pharmacology principle?
A. “Taking more medication will always make it work faster.”
B. “The amount of medication in my body can affect how well it
works.”
C. “All medications affect everyone in the same way.”
D. “If I miss a dose, I should double the next dose.”
Correct Answer: B
Rationale:
The concentration of a medication in the body influences its
therapeutic effect and potential for toxicity. Taking more
medication does not always improve effectiveness and may
increase adverse effects. Individual responses to medications
vary, and doubling doses without provider direction can be
dangerous.
Question 2
A nurse administers an oral medication. Which process occurs
when the drug moves from the gastrointestinal tract into the
bloodstream?
A. Distribution
,B. Metabolism
C. Absorption
D. Excretion
Correct Answer: C
Rationale:
Absorption is the movement of a drug from its site of
administration into the bloodstream. Distribution occurs after
absorption when the drug moves to tissues. Metabolism refers
to chemical alteration of the drug, and excretion is the removal
of the drug from the body.
Question 3
A patient asks why the healthcare provider reviews allergies
before prescribing a medication. What is the nurse’s best
response?
A. “Allergies help determine the cost of treatment.”
B. “Allergic reactions can cause serious harm and affect
medication selection.”
C. “Allergies only affect injectable medications.”
D. “Allergies determine how quickly medications are absorbed.”
Correct Answer: B
, Rationale:
Medication allergies can result in reactions ranging from mild
rashes to life-threatening anaphylaxis. Identifying allergies helps
prevent adverse events and guides safe medication selection.
Allergies are not limited to injectable medications and do not
primarily affect absorption rates.
Question 4
A nurse evaluates the effectiveness of a newly prescribed
analgesic. Which finding best indicates a therapeutic response?
A. Blood pressure increases significantly.
B. The patient reports decreased pain.
C. The patient develops a rash.
D. Respiratory rate decreases below normal.
Correct Answer: B
Rationale:
A therapeutic response is the intended beneficial effect of a
medication. For an analgesic, decreased pain indicates
effectiveness. A rash suggests an adverse reaction, while
significant blood pressure changes or respiratory depression
may represent unwanted effects.
