(1) Subject to subsections (2) and (3) of this section, a volunteer health practitioner shall adhere to the scope of practice for a similarly licensed practitioner established by the licensing provisions, practice acts, or other laws of this state.

(2) Except as otherwise provided in subsection (3) of this section, this chapter does not authorize a volunteer health practitioner to provide services that are outside the practitioner's scope of practice, even if a similarly licensed practitioner in this state would be permitted to provide the services.

(3) The department may modify or restrict the health or veterinary services that volunteer health practitioners may provide pursuant to this chapter. An order under this subsection may take effect immediately, without prior notice or comment, and is not a rule within the meaning of the administrative procedure act, chapter 34.05 RCW.

(4) A host entity may restrict the health or veterinary services that a volunteer health practitioner may provide pursuant to this chapter.

(5) A volunteer health practitioner does not engage in unauthorized practice unless the practitioner has reason to know of any limitation, modification, or restriction under this section or that a similarly licensed practitioner in this state would not be permitted to provide the services. A volunteer health practitioner has reason to know of a limitation, modification, or restriction or that a similarly licensed practitioner in this state would not be permitted to provide a service if:

(a) The practitioner knows the limitation, modification, or restriction exists or that a similarly licensed practitioner in this state would not be permitted to provide the service; or

(b) From all the facts and circumstances known to the practitioner at the relevant time, a reasonable person would conclude that the limitation, modification, or restriction exists or that a similarly licensed practitioner in this state would not be permitted to provide the service.

(6) In addition to the authority granted by law of this state other than this chapter to regulate the conduct of health practitioners, a licensing board or other disciplinary authority in this state:

(a) May impose administrative sanctions upon a health practitioner licensed in this state for conduct outside of this state in response to an out-of-state emergency;

(b) May impose administrative sanctions upon a practitioner not licensed in this state for conduct in this state in response to an in-state emergency; and

(c) Shall report any administrative sanctions imposed upon a practitioner licensed in another state to the appropriate licensing board or other disciplinary authority in any other state in which the practitioner is known to be licensed.

(7) In determining whether to impose administrative sanctions under subsection (6) of this section, a licensing board or other disciplinary authority shall consider the circumstances in which the conduct took place, including any exigent circumstances, and the practitioner's scope of practice, education, training, experience, and specialized skill.
