When moving to another state, what is the nurse responsible for becoming familiar with?

- B. Local provider's Drug Enforcement Agency (DEA) number for prescribing controlled substances
- C. The agency monitoring controlled substances in the new state
- D. Board of Nursing regulations of controlled substances in the new state
Correct Answer: A
Rationale: The nurse needs to learn local policies and procedures for controlled substance administration because they can vary with some local governments more rigorous than others. Nurses do not memorize a provider's DEA numbers. The DEA is a federal agency that monitors controlled substances in all states. State boards of nursing do not regulate controlled substances but may regulate how controlled substances are administered by nurses.
