Question 1
,A nurse explains why the prescribed oral dose of a medication is
higher than the intravenous dose of the same medication.
Which explanation by the nurse is most accurate?
A. Oral medications are always less potent than injectable
medications.
B. Some of the orally administered drug is metabolized before
reaching the systemic circulation.
C. Intravenous medications remain in body fat longer than oral
medications.
D. Oral medications are eliminated by the kidneys before
entering the bloodstream.
Correct Answer: B
Rationale:
Many orally administered drugs undergo first-pass metabolism
in the liver before reaching systemic circulation, reducing the
amount of active drug available. This often necessitates a higher
oral dose compared with intravenous administration. Oral
medications are not inherently less potent (A). Intravenous
drugs are not retained longer in fat solely because of the route
(C). Oral drugs are absorbed into the bloodstream before renal
elimination occurs (D).
Question 2
,A patient asks why two medications with different brand names
contain the same active ingredient. Which response by the
nurse is most appropriate?
A. "Brand names identify different manufacturers, while the
active ingredient may be the same."
B. "Brand-name medications contain stronger doses than
generic medications."
C. "Generic medications are used only in hospitals."
D. "Only brand-name medications are approved for patient
use."
Correct Answer: A
Rationale:
A medication may be marketed under different brand names
while containing the same generic (nonproprietary) drug.
Generic medications contain the same active ingredient and
meet standards for quality, safety, and effectiveness. Generic
drugs are used in many healthcare settings, and brand-name
products are not inherently stronger or more effective.
Question 3
, Before administering a medication, a nurse verifies the patient's
identity using two approved identifiers. What is the primary
purpose of this action?
A. To reduce medication costs
B. To prevent medication administration errors
C. To improve medication absorption
D. To shorten documentation time
Correct Answer: B
Rationale:
Verifying patient identity with two approved identifiers is a
fundamental medication safety practice that helps ensure the
correct patient receives the correct medication. This process is
unrelated to medication cost, absorption, or documentation
efficiency.
Question 4
A patient is prescribed a medication with a narrow therapeutic
range. Which nursing action is the highest priority?
A. Encourage increased fluid intake regardless of diagnosis.
B. Administer the medication without monitoring.
C. Monitor for therapeutic response and signs of toxicity.
