When a physician or other authorized prescriber conveys a medication order to a licensed pharmacist by verbal means for a patient in a health care facility licensed pursuant to this chapter, or for a client in a facility operated or licensed by the Department of Developmental Services, such order shall be received and immediately committed to writing in the patient’s or client’s chart by the pharmacist. Any order so written may be acted upon by the facility’s nurses and physician assistants with the same authority as if the order were received directly from the prescriber. Any order conveyed in this manner shall be countersigned by the prescriber within twenty-four hours unless otherwise provided by state or federal law or regulations.
