22 Tex. Admin. Code § 225.15
BON § 217.11(1) of this title (relating to Standards of Nursing Practice) requires RNs to know and conform to all laws and regulations affecting their area of practice. The RN authorizing an unlicensed person to perform tasks in independent living environments should be aware that, in addition to this chapter, various laws and regulations may apply including, but not limited to, laws and regulations governing home and community support service agencies and Medicare and Medicaid regulations. In situations where a RN's practice is governed by multiple laws and regulations that impose different requirements, the RN must comply with them all and if inconsistent, the most restrictive requirement(s) governs. For example, if one regulation requires a RN to make a supervisory visit every 14 days and another leaves it to the RN's professional judgment, the RN would have to visit at least every 14 days or more frequently, if that is what the RN's professional judgment indicated.
