UPDATE 2026
A nurse practitioner practices in a state granting full prescriptive authority. Which
action best reflects this authority?
A. Prescribing only noncontrolled medications under physician supervision
B. Prescribing Schedule II-V medications independently
C. Prescribing only medications listed in institutional protocols
D. Recommending over-the-counter therapies only
B
Rationale: Full prescriptive authority allows providers to prescribe all medications,
including controlled substances, without mandated supervision.
A provider practicing under limited prescriptive authority attempts to prescribe a
Schedule II medication independently. What is the most appropriate analysis?
A. This is appropriate in all states
B. It is acceptable if the patient consents
C. It may violate state law and professional regulations
D. It is appropriate if the medication is not refilled
C
Rationale: Limited prescriptive authority restricts medication classes or requires
supervision. Prescribing outside scope may violate regulatory standards.
,Before prescribing a beta-blocker to a patient with asthma, which prescribing
consideration is most critical?
A. Medication cost
B. Drug absorption rate
C. Comorbid conditions
D. Route of administration
C
Rationale: Asthma is a key comorbidity because beta-blockers may worsen
bronchospasm. Patient-specific factors are essential in safe prescribing.
An elderly patient with low albumin is prescribed a highly protein-bound drug.
What is the likely outcome?
A. Decreased therapeutic effect
B. Increased free drug concentration
C. Reduced half-life
D. Faster renal clearance
B
Rationale: Lower albumin increases free (active) drug levels, increasing risk of toxicity.
A neonate receives a medication primarily cleared renally. Which outcome is
most likely?
A. Rapid drug elimination
B. Drug accumulation
C. No change in half-life
D. Increased metabolism
,B
Rationale: Neonates have immature renal function, leading to slower clearance and
potential accumulation.
A drug with a short half-life is prescribed once daily. What is the likely
consequence?
A. Drug toxicity
B. Subtherapeutic levels before next dose
C. Increased protein binding
D. Prolonged steady-state levels
B
Rationale: Short half-life drugs require more frequent dosing to maintain therapeutic
concentrations.
A patient taking warfarin is prescribed an enzyme inhibitor. What is the expected
pharmacokinetic effect?
A. Reduced drug concentration
B. Increased metabolism
C. Elevated warfarin levels and bleeding risk
D. Decreased half-life
C
Rationale: Enzyme inhibition slows metabolism, increasing drug levels and risk of
adverse effects.
Which scenario best represents a pharmacodynamic drug interaction?
A. Antacid reducing antibiotic absorption
, B. Two CNS depressants increasing sedation
C. Liver enzyme induction decreasing drug levels
D. Renal impairment reducing drug excretion
B
Rationale: Pharmacodynamic interactions occur when drugs have additive or opposing
physiological effects.
A pregnant patient in her first trimester requires treatment. Which principle
should guide therapy?
A. Avoid all medications
B. Use category X drugs cautiously
C. Balance maternal benefit against fetal risk
D. Prescribe only herbal supplements
C
Rationale: Risk-benefit assessment is central, especially in the first trimester when
teratogenic risk is highest.
Which medication is contraindicated during pregnancy?
A. Insulin
B. Penicillin
C. Isotretinoin
D. Cephalexin
C
Rationale: Isotretinoin is teratogenic and classified as pregnancy category X.
