Correct Answer: A

Rationale: Potency' is correct because it defines the concentration or strength of active ingredients needed for a therapeutic effect. 'Quality' is about overall standards, not concentration specifically. 'Efficacy' is the ability to produce results, not ingredient level. 'Purity' is absence of contaminants, not concentration. Potency directly relates to dosage and effect strength, a key pharmacology concept distinguishing it from the others.

Correct Answer: C

Rationale: Schedule III' is correct because these drugs (e.g., anabolic steroids) have moderate abuse potential, accepted medical use, and allow phoned prescriptions with up to five refills in six months under DEA rules. 'Schedule I' has no use. 'Schedule II' requires written prescriptions. 'Schedule IV' has lower risk but similar refill rules. Schedule III balances risk and flexibility, per pharmacology scheduling.

Correct Answer: A

Rationale: True' is correct because the DEA tracks controlled substances (Schedules I-V) from manufacture to sale or use under the 1970 Act to prevent diversion. 'False' overlooks this enforcement role. 'Not applicable' pads C/D. The DEA's oversight, distinct from FDA regulation, ensures compliance across the supply chain, per pharmacology law.

Correct Answer: A

Rationale: True' is correct because photocopying prescriptions creates a record to verify authenticity, deterring forgery per security recommendations. 'False' dismisses this effective measure. 'Not applicable' fills C/D. This practice, alongside secure pads, enhances traceability, a practical step in pharmacology settings.
