Pharmacology and the Nursing Process in LPN Practice
Question 1
A student nurse asks the instructor to define "pharmacology." Which response by the instructor is
most accurate?
A. The study of the legal aspects of medication administration
B. The study of drugs and their interactions with living organisms ✓
C. The study of the chemical composition of medications only
D. The study of disease processes and their treatment
Correct Answer: B
Rationale:
Pharmacology is broadly defined as the scientific study of drugs, including their origin, chemistry,
physiologic effects, and interactions with living organisms. This definition encompasses both how the
body affects a drug (pharmacokinetics) and how a drug affects the body (pharmacodynamics).
Why the other options are incorrect:
● A: Legal aspects of administration fall under nursing law and the Nurse Practice Act, not the core
definition of pharmacology.
● C: Chemical composition is only one narrow component (pharmaceutics), not the full scope of the
discipline.
● D: This describes pathology/medicine broadly, not pharmacology specifically, which focuses on drug
action rather than disease study alone.
Question 2
Which of the following best describes the LPN/LVN's role within the nursing process when
administering medications?
A. The LPN independently establishes the nursing diagnosis without RN input
B. The LPN collects data, contributes to planning, implements prescribed therapy, and reports
findings to the RN ✓
C. The LPN is restricted to assessment activities only
D. The LPN may revise the plan of care without consulting the supervising RN
Correct Answer: B
Rationale:
Under most state Nurse Practice Acts, the LPN/LVN functions under the supervision of an RN or
provider and contributes to all steps of the nursing process, particularly data collection,
implementation of the plan of care (including medication administration), and reporting/documenting
findings — but does not independently formulate nursing diagnoses or revise the overall plan of care.
, Why the other options are incorrect:
● A: Formulating the formal nursing diagnosis is generally an RN responsibility; the LPN contributes
data but does not do this independently.
● C: The LPN's role extends well beyond assessment to include implementation and evaluation
activities within their scope.
● D: Care plan revision requires RN oversight; the LPN reports changes but does not unilaterally alter
the plan.
Question 3
A nurse is caring for a patient who tells the nurse, "I feel nauseated and dizzy." This information is an
example of which type of assessment data?
A. Objective data
B. Subjective data ✓
C. Secondary data
D. Diagnostic data
Correct Answer: B
Rationale:
Subjective data consists of information reported by the patient that reflects their own perception of
their condition, such as symptoms like nausea or dizziness. These findings cannot be directly measured
or observed by the nurse.
Why the other options are incorrect:
● A: Objective data are measurable/observable findings, such as vital signs or lab values, not patient-
reported symptoms.
● C: Secondary data comes from sources other than the patient, such as family members or the
medical record.
● D: Diagnostic data refers to results of tests and procedures, which is a form of objective data, not a
patient statement.
Question 4
Which step of the nursing process involves setting measurable, patient-centered goals related to drug
therapy?
A. Assessment
B. Nursing diagnosis
C. Planning ✓
D. Evaluation
Correct Answer: C
Rationale:
The planning phase involves establishing realistic, measurable goals and expected outcomes based on
the identified nursing diagnoses, which then guide the interventions carried out during
implementation.
Why the other options are incorrect:
● A: Assessment is the data-collection phase that precedes goal-setting; goals are not established here.
