Modifies provisions relating to the administration of controlled substances by nurses

HB 831 expands prescribing authority for certain nurses regarding controlled substances. It allows advanced practice registered nurses (APRNs) with specific certification to prescribe Schedule III-V controlled substances and limited Schedule II (hydrocodone) medications for hospice patients, but only under written agreements with physicians and with a 120-hour supply limit without refills. Certified nurse anesthetists (CNAs) may administer controlled substances during anesthesia care without needing special prescribing certification, but cannot prescribe them. The bill prohibits self-prescribing or prescribing for family members and requires detailed written collaborative practice agreements between APRNs and physicians.
