Fundamentals Midterm Exam | 100 + Actual Study
Questions and Answers + Expert Rationales | 2026
Updated | 100% correct
1. What does the scope of an APRN's prescriptive authority include beyond standard
medications?
A. Only prescription drugs and controlled substances
B. Durable Medical Equipment (DME) and medical services such as PT and OT
C. Only over-the-counter medications
D. Only hospital-administered medications
Correct Answer: B
Expert Rationale: Prescriptive authority extends to Durable Medical Equipment (DME)—such as
oxygen equipment, hospital beds, and mobility aids—as well as essential medical services like
Physical and Occupational Therapy. It is a comprehensive role governed by state laws that
requires deep knowledge of drug mechanisms, safety, and a patient's existing medication profile
to prevent adverse interactions. Prescriptive authority encompasses more than writing a
prescription correctly; it requires adherence to ethical guidelines to ensure patients are
safeguarded from harm.
2. What are the primary advantages of "Full Practice Authority" for a Nurse Practitioner?
A. NPs must practice under physician supervision at all times
B. NPs have autonomy to evaluate, diagnose, order tests, and prescribe medications without
physician oversight
C. NPs can only prescribe non-controlled substances
D. NPs must have a collaborative agreement with a physician
Correct Answer: B
Expert Rationale: Full practice authority allows NPs to operate at the highest level of their
training. This includes the autonomy to evaluate, diagnose, order diagnostic tests, and manage
treatments—including the prescription of controlled substances—without the requirement of
physician supervision or a collaborative agreement . State laws govern the degree of
,collaboration or supervision of a physician, and the State Board of Medicine, Pharmacy, or
Nursing determine the extent of prescriptive authority in each state .
3. How does an APRN ensure patient safety and reduce legal liability through prudent
prescribing?
A. Prescribing medications for family members to save time
B. Confirming a formal provider-patient relationship exists and documenting a comprehensive
history and physical exam
C. Prescribing based solely on patient requests
D. Avoiding all documentation to reduce workload
Correct Answer: B
Expert Rationale: Prudent prescribing is a deliberate process that relies on rigorous
documentation and ethical boundaries, specifically: confirming a formal provider-patient
relationship exists, documenting a comprehensive history and physical exam before prescribing,
recording discussions about risks, side effects, and alternative treatments, outlining a clear plan
for drug titration and monitoring, and strictly avoiding the prescription of medications for
oneself, family members, or friends . Rational drug selection requires a logical approach that
includes the formulation of a diagnosis based on clinical reasoning and the selection and
monitoring of the most appropriate pharmacological treatment.
4. What is the fundamental difference between administering a medication and prescribing
one?
A. They are the same process
B. Administration is a complex decision-making process; prescribing is giving a dose
C. Prescribing is a complex decision-making process involving selecting the correct agent,
determining dosage, and setting duration of therapy
D. There is no difference
Correct Answer: C
Expert Rationale: While administration is the act of giving a dose, prescribing is a complex
decision-making process. It involves selecting the correct agent, determining the precise
dosage, and setting the duration of therapy based on nationally recognized safety standards and
the unique needs of the patient . Rational drug selection requires a logical approach that
,includes the formulation of a diagnosis based on clinical reasoning and the selection and
monitoring of the most appropriate pharmacological treatment .
5. Which of the following is a key component of prudent prescribing practices?
A. Prescribing for self and family members
B. Documentation of a provider-patient relationship and thorough history and physical
C. Avoiding discussion of risk factors with patients
D. Prescribing without monitoring plans
Correct Answer: B
Expert Rationale: Prescription writing requires prudent and deliberate decision-making
processes to maintain patient safety and reduce liability, including: documentation of a
provider-patient relationship for the recipient of the prescribed medications, documentation of
a thorough history and physical examination, documentation of discussions regarding risk
factors, side effects, or therapy options, documentation of drug monitoring or titration plan, and
avoidance of prescribing medications for self, family, or friends .
6. What are the Beers Criteria used for?
A. Identifying drugs that should be used in all older adults
B. Identifying drugs with a high likelihood of causing adverse effects in older adults (65+)
C. Identifying drugs that are safe for use in pediatrics
D. Identifying drugs that are safe for use during pregnancy
Correct Answer: B
Expert Rationale: The Beers Criteria identifies drugs with a high likelihood of causing adverse
effects in older adults. Accordingly, drugs on this list should generally be avoided in adults older
than 65 years except when the benefits are significantly greater than the risks . This is a critical
tool for prescribers managing geriatric patients.
7. What is the definition of pharmacodynamics?
A. The study of drug movement throughout the body
B. The study of how genes affect a person's response to drugs
C. The study of the biochemical and physiologic effects of drugs on the body and the molecular
, mechanisms by which those effects are produced
D. The study of drug-drug interactions
Correct Answer: C
Expert Rationale: Pharmacodynamics is the study of the biochemical and physiologic effects of
drugs on the body and the molecular mechanisms by which those effects are produced . It
focuses on what the drug does to the body, including receptor binding, dose-response
relationships, and mechanisms of action.
8. What is the definition of pharmacokinetics?
A. The study of the biochemical effects of drugs on the body
B. The study of drug movement throughout the body
C. The study of how genes affect a person's response to drugs
D. The study of drug safety profiles
Correct Answer: B
Expert Rationale: Pharmacokinetics is the study of drug movement throughout the body . It
encompasses the processes of absorption, distribution, metabolism, and excretion (ADME).
Most drug metabolism takes place in the liver and is performed by the hepatic microsomal
enzyme system, also known as the P450 system .
9. What is the purpose of pharmacogenomics?
A. To study drug side effects
B. To combine the sciences of genomics and pharmacology to provide individualized, targeted,
safe drug therapies to patients
C. To study drug manufacturing processes
D. To study drug costs
Correct Answer: B
Expert Rationale: Pharmacogenomics is the study of how genes affect a person's response to
drugs. The purpose is to combine the sciences of genomics and pharmacology to provide
individualized, targeted, safe drug therapies to patients . This allows for personalized medicine
based on genetic variability.
