Which statement is correct regarding arterial lines?

Incorrect

Blood can be drawn off arterial lines to obtain labs
Arterial lines can be used to give IV medications just like an IV site
Arterial lines can be used to obtain continuous blood pressures, but even when used correctly these blood pressures are not as accurate as manual blood pressures.
Arterial lines can be used as an access point for performing cardiovascular procedures

Rationale

Arterial lines can be used to draw blood work. Arterial lines cannot be used as an access point for performing cardiovascular procedures; this requires a larger catheter and advance monitoring in a surgical environment. Many IV medications can be harmful when given arterially, and the arterial line cannot be used to give IV medications. Taking blood pressure using an arterial line is the most accurate method of obtaining a blood pressure.
