QUESTIONS WITH VERIFIED ANSWERS DETAILED

Introduction to Clinical Pharmacology — Test Bank
SECTION 1: PHARMACOLOGY AND THE NURSING PROCESS (Questions 1–15)
1. Which monitoring plan is most appropriate for a patient receiving a drug with a narrow
therapeutic index?
A. Timing of levels for narrow-therapeutic-index drugs
B. Time required for plasma concentration to decrease by about half during elimination
C. Steady state often takes several half-lives
D. Estimate drug accumulation and time to steady state
Correct Answer: A
Rationale: Monitoring should target the desired response and predictable toxicities. For narrow-
therapeutic-index drugs, the appropriate focus is timing of levels to ensure the drug remains
within the therapeutic range and to prevent toxicity. This connects pharmacology to patient
safety rather than substituting an indication, mechanism, or teaching statement for an actual
monitoring plan.

2. A patient taking a medication with high first-pass metabolism states, "I can ignore this
precaution: do not assume oral and IV doses are equivalent." Which action should the nurse
take?
A. Document the statement and continue with the current dose
B. Provide additional teaching about the difference between oral and IV routes
C. Notify the provider to change the route to IV
D. Ask the patient to repeat back the information
Correct Answer: B
Rationale: The incorrect statement dismisses an important safety point: do not assume oral and
IV doses are equivalent. The other statements appropriately distinguish the drug's clinical role,
patient teaching, and monitoring. The nurse should provide additional teaching to correct this
misunderstanding.
3. The nurse is administering a medication to a patient. Which action demonstrates the
evaluation phase of the nursing process?
A. Asking the patient if they have any allergies
B. Checking the patient's blood pressure 30 minutes after giving an antihypertensive medication
C. Explaining the purpose of the medication to the patient
D. Setting the infusion rate on an IV pump
Correct Answer: B
Rationale: Evaluation involves assessing the patient's response to the medication (therapeutic
effect and adverse effects). Asking allergies is assessment; explaining is implementation; setting
the infusion rate is implementation.
4. A nurse is preparing to administer a medication. Which action is part of the "six rights" of
medication administration?
A. Right room number
B. Right diagnosis

C. Right dose
D. Right physician
Correct Answer: C
Rationale: The six rights of medication administration are: right patient, right drug, right dose,
right route, right time, and right documentation. Some sources include right reason and right
response as additional rights.
5. Before administering a medication, the nurse must verify the patient's identity using:
A. The patient's room number
B. The patient's bed number
C. Two patient identifiers (e.g., name and date of birth)
D. The patient's diagnosis
Correct Answer: C
Rationale: The Joint Commission requires at least two patient identifiers (e.g., name, date of
birth, medical record number) before administering medications, blood products, or performing
procedures. Room and bed numbers are not acceptable identifiers.
6. Which of the following is a responsibility of the LPN/LVN regarding medication
administration?
A. Prescribing medications
B. Independently adjusting medication dosages without an order
C. Administering medications as ordered by the provider
D. Diagnosing conditions that require medication
Correct Answer: C
Rationale: The LPN/LVN is responsible for administering medications as ordered by the provider.
Prescribing, independently adjusting dosages, and diagnosing are outside the scope of practice
for an LPN/LVN.

7. The LPN is collecting data for the initial assessment of a patient upon admission to a long-
term care facility before giving the patient's prescribed drugs. What is the highest priority
action for the LPN during this assessment?
A. Obtain any special equipment that will be needed to give the patient's drug
B. Administer all medications immediately
C. Develop a comprehensive care plan independently
D. Diagnose the patient's condition
Correct Answer: A
Rationale: During the initial assessment, the LPN should gather data including any special
equipment needed for medication administration. Administering medications, developing care
plans, and diagnosing are not the highest priority at this stage or are outside the LPN scope.
8. The study of drug absorption, distribution, metabolism, and excretion is known as:
A. Pharmacotherapeutics
B. Pharmacodynamics
C. Pharmacokinetics
D. Pharmacy
E. Posology
Correct Answer: C
Rationale: Pharmacokinetics is the study of drug absorption, distribution, metabolism, and
excretion. Pharmacodynamics is the study of what the drug does to the body.
9. The medical situation when a particular drug should not be administered is referred to as:
A. Side effect
B. Adverse effect
C. Drug allergy
D. Contraindication
E. Antagonism
