Louisiana State Police Academy Cadet Practice Exam

In the context of obtaining blood samples for DWI (Driving While Intoxicated) testing with a search warrant, the correct answer highlights that a Licensed Practical Nurse (LPN) is permitted to perform this task under the appropriate legal circumstances. LPNs are trained to perform various medical procedures, including venipuncture, which is the process of drawing blood from a patient.

When such procedures are performed with a search warrant, it indicates that law enforcement has followed legal protocols to ensure that the individual's rights are respected while gathering evidence. The involvement of an LPN in this process underscores the roles that trained medical professionals can play in supporting law enforcement activities while adhering to medical standards and laws.

The other professions listed may not have the same legal status or training to perform blood draws in this specific context, or they might have limitations based on state laws regarding their scope of practice when it comes to invasive procedures necessitated by legal actions.
