Several bills working their way through the Florida Legislature would give nurse practitioners the ability to prescribe stronger medications and clarify other duties. A second Senate committee has approved a bill that spells out the ability of highly trained nurses, known as practitioners, toorder controlled substances in the hospital. Senator Denise Grimsley, R-Sebring, is a registered nurse who sponsors the bill. She gave the Senate Finance and Tax committee a brief explanation about prescribing versus ordering. "Prescribe is when a prescription is written and taken to the pharmacy. Order is when it's ordered in the hospital," Grimsley explained.
