Texas BON Prescriptive Rules
NURS 5334 Quiz 1 Questions (1–50)
Prescribing Basics (4 Questions)

1. According to the Texas BON, which element must be included in a prescription
written by an Advanced Practice Registered Nurse (APRN)?
o A) Patient’s insurance provider
o B) Prescriber’s DEA number for non-controlled substances
o C) Patient’s name and date of birth
o D) Prescriber’s home address
o Answer: C. Patient’s name and date of birth
o Rationale: Texas BON requires prescriptions to include the patient’s name, date
of birth, drug name, strength, administration instructions, quantity, refills,
prescriber’s name, address, telephone number, and NPI number. A DEA number
is only required for controlled substances.
2. In Texas, APRN prescriptive authority is described as:
o A) Highly flexible
o B) Moderately restricted
o C) Unrestricted
o D) Very restricted
o Answer: D. Very restricted
o Rationale: Texas has very restricted prescriptive authority, requiring APRNs to
have a prescriptive authority agreement with a supervising physician.
3. A nurse practitioner writes a prescription for amoxicillin. Which formatting rule
should be followed to prevent medication errors?
o A) Use trailing zeros (e.g., 5.0 mg)
o B) Use leading zeros (e.g., 0.5 mg)
o C) Abbreviate “daily” as “q.d.”
o D) Omit the prescriber’s signature
o Answer: B. Use leading zeros (e.g., 0.5 mg)
o Rationale: Leading zeros prevent misinterpretation (e.g., .5 mg read as 5 mg).
Trailing zeros and abbreviations like “q.d.” are error-prone and should be
avoided.

, 4. Which statement is true regarding Texas BON rules for APRN prescribing of
controlled substances?
o A) APRNs can prescribe Schedule I drugs independently
o B) A DEA number is required for Schedule II–V drugs
o C) Prescriptions for controlled substances do not require a supervising physician
o D) Controlled substances can be prescribed without a patient’s address
o Answer: B. A DEA number is required for Schedule II–V drugs
o Rationale: Texas requires a DEA number for prescribing controlled substances
(Schedules II–V) and a prescriptive authority agreement with a physician.

Pharmacology Principles (5 Questions)

5. What is the definition of pharmacodynamics?
o A) The study of how drugs are absorbed and excreted
o B) The effect of drugs on the body
o C) The influence of genetic factors on drug response
o D) The time required for a drug to decline by 50%
o Answer: B. The effect of drugs on the body
o Rationale: Pharmacodynamics studies how drugs interact with receptors to
produce effects, while pharmacokinetics covers absorption, distribution,
metabolism, and excretion.
6. Which term describes the percentage of a drug dose that survives first-pass
metabolism and reaches the bloodstream?
o A) Half-life
o B) Bioavailability
o C) Therapeutic range
o D) Pharmacogenomics
o Answer: B. Bioavailability
o Rationale: Bioavailability measures the fraction of an administered drug that
reaches systemic circulation, affected by first-pass metabolism in the liver.
7. A drug with a short half-life requires:
o A) Less frequent dosing
o B) More frequent dosing
o C) No dose adjustment
o D) Intravenous administration only
o Answer: B. More frequent dosing
o Rationale: A short half-life means the drug is eliminated quickly, requiring more
frequent dosing to maintain therapeutic levels.
8. What is the role of an antagonist in pharmacodynamics?
o A) Stimulates receptors fully
o B) Binds to receptors without activating them
o C) Partially stimulates receptors
o D) Increases drug metabolism
o Answer: B. Binds to receptors without activating them
o Rationale: Antagonists bind to receptors but lack intrinsic activity, blocking the
action of agonists (e.g., naloxone).
