PHARMACOTHERAPEUTICS FOR ADVANCED PRACTICE NURSE PRESCRIBERS, 5TH
EDITION (WOO & ROBINSON) – 250 EXAM-STYLE QUESTIONS
SECTION 1: ROLE OF THE NURSE PRACTITIONER AS PRESCRIBER & BASIC
PHARMACOLOGY (Questions 1-50)
1. Nurse practitioner prescriptive authority is regulated by:
A) The National Council of State Boards of Nursing
B) The U.S. Drug Enforcement Administration
C) The State Board of Nursing for each state
D) The State Board of Pharmacy
Correct Answer: C
Rationale: Prescriptive authority for nurse practitioners is regulated at the state level by
each state's Board of Nursing. State laws determine the scope of practice,
requirements for prescriptive authority, and whether independent prescribing is
permitted .
2. The benefits to the patient of having an Advanced Practice Registered Nurse
(APRN) prescriber include:
A) Nurses know more about pharmacology than other prescribers because they take it
both in their basic nursing program and in their APRN program
B) Nurses care for the patient from a holistic approach and include the patient in
decision making regarding their care
C) APRNs are less likely to prescribe narcotics and other controlled substances
D) APRNs are able to prescribe independently in all states
, Page 2 of 79
Correct Answer: B
Rationale: APRNs are known for their holistic approach to patient care, which includes
considering the whole patient—physical, psychological, social, and environmental
factors—and involving patients in shared decision-making about their treatment .
3. Clinical judgment in prescribing includes:
A) Factoring in the cost to the patient of the medication prescribed
B) Always prescribing the newest medication available for the disease process
C) Handing out drug samples to poor patients
D) Prescribing all generic medications to cut costs
Correct Answer: A
Rationale: Clinical judgment in prescribing involves considering multiple factors
including the cost to the patient, patient preferences, formulary restrictions, and
evidence-based guidelines. Cost is an important consideration that affects medication
adherence .
4. Criteria for choosing an effective drug for a disorder include:
A) Asking the patient what drug they think would work best for them
B) Consulting nationally recognized guidelines for disease management
C) Prescribing medications that are available as samples before writing a prescription
D) Following U.S. Drug Enforcement Administration guidelines for prescribing
Correct Answer: B
Rationale: Evidence-based practice requires consulting nationally recognized
guidelines for disease management when selecting pharmacotherapy. These guidelines
synthesize the best available evidence to guide prescribing decisions .
5. A patient's nutritional intake and laboratory results reflect hypoalbuminemia.
This is critical to prescribing because:
A) Distribution of drugs to target tissue may be affected
B) The solubility of the drug will not match the site of absorption
C) There will be less free drug available to generate an effect
D) Drugs bound to albumin are readily excreted by the kidneys
Correct Answer: A
, Page 3 of 79
Rationale: Hypoalbuminemia reduces the protein-binding capacity of plasma, leading
to increased free drug concentrations. This can significantly affect drug distribution and
increase the risk of toxicity, especially for highly protein-bound drugs .
6. Drugs that have a significant first-pass effect:
A) Must be given by the enteral (oral) route only
B) Bypass the hepatic circulation
C) Are rapidly metabolized by the liver and may have little if any desired action
D) Are converted by the liver to more active and fat-soluble forms
Correct Answer: C
Rationale: Drugs with significant first-pass effect are extensively metabolized by the
liver before reaching systemic circulation. This may result in reduced bioavailability and
diminished therapeutic effect, often requiring higher oral doses or alternative routes of
administration .
7. The route of excretion of a volatile drug will likely be the:
A) Kidneys
B) Lungs
C) Bile and feces
D) Skin
Correct Answer: B
Rationale: Volatile drugs (such as inhalation anesthetics) are primarily excreted
through the lungs via exhalation. This route of elimination is important for drugs with
high vapor pressure .
8. Medroxyprogesterone (Depo Provera) is prescribed intramuscularly (IM) to create
a storage reservoir of the drug. Storage reservoirs:
A) Assure that the drug will reach its intended target tissue
B) Are the reason for giving loading doses
C) Increase the length of time a drug is available and active
D) Are most common in collagen tissues
Correct Answer: C
, Page 4 of 79
Rationale: Storage reservoirs (depots) in tissues such as fat, muscle, and bone prolong
the duration of drug action by slowly releasing the drug into the circulation. This allows
for less frequent dosing and sustained therapeutic effects .
9. The NP chooses to give cephalexin every 8 hours based on knowledge of the
drug's:
A) Propensity to go to the target receptor
B) Biological half-life
C) Pharmacodynamics
D) Safety and side effects
Correct Answer: B
Rationale: The dosing interval is primarily determined by the drug's biological half-life—
the time required for the drug concentration to decrease by 50%. Drugs with shorter
half-lives require more frequent dosing to maintain therapeutic levels .
10. Azithromycin dosing requires that the first day's dosage be twice those of the
other 4 days of the prescription. This is considered a loading dose. A loading dose:
A) Rapidly achieves drug levels in the therapeutic range
B) Requires four to five half-lives to attain
C) Is influenced by renal function
D) Is directly related to the drug circulating to the target tissues
Correct Answer: A
Rationale: A loading dose is an initial higher dose given to rapidly achieve therapeutic
drug levels in the body. This is particularly important for drugs with long half-lives,
allowing therapeutic effects to be achieved more quickly than would occur with
maintenance dosing alone .
11. The point in time on the drug concentration curve that indicates the first sign of
a therapeutic effect is the:
A) Minimum adverse effect level
B) Peak of action
C) Onset of action
D) Duration of action
Correct Answer: C
