Which of the following can advanced practice nurses (APNs) do?

Advanced Practice Nurses (APNs) have specific legal capabilities that include prescribing and, in some instances, dispensing medication. The correct statement is that APNs can utilize the collaborating physician's DEA number when prescribing controlled substances. This practice allows APNs to prescribe medications under the supervision of a physician, thereby ensuring proper regulation and compliance with both state and federal laws.

Utilizing the collaborating physician's DEA number is particularly important when APNs work within a team and can facilitate patient access to necessary medications without needing separate DEA registration for every APN, streamlining patient care.

The other statements do not accurately reflect the capabilities of APNs within Ohio's legal framework. While APNs are allowed to dispense samples, this does not encompass all possible medications and often carries restrictions. Additionally, APNs are authorized to e-prescribe, thus making statement B incorrect as it suggests a limitation that does not exist.
