Final answer:
PAs can prescribe CV non-opioids for a variable day supply depending on state laws; for the exact limit, state regulations or supervising physician should be consulted.
Step-by-step explanation:
The ability of a Physician Assistant (PA) to prescribe medication, including controlled substances, varies based on the state's laws where the PA practices. Generally, a PA may prescribe Schedule V (CV non-opioids) medications, which are considered to have a lower potential for abuse, up to a certain day supply unless otherwise indicated by law or determined by the specific patient's medical needs. The exact day supply a PA can prescribe could be subject to change and is not universally standardized, therefore, it's essential to consult the specific state's regulations or the supervising physician's guidelines.
