PMHNP Practice Environment Nurse practitioners have a differing scope of practice in every state. Each state has its board of nursing that determines its credentialing process and the extent of practice within the state. This paper compares the practice environment in Arizona and Texas and discusses credentialing issues and the certification process. PMHNP Practice Environment in Arizona The scope of nursing practice varies with different states in the US. Most nurses covet the state of Arizona as it has the most lenient degree of practice policy. First, nurse practitioners in Arizona can practice independently and not necessarily have to practice under or collaborate with a licensed physician like in other states (Kandrack, Barnes & Martsolf, 2019). Nurse practitioners are expected to refer patients who are beyond their competency to another care provider or consult with them. They are also required to only practice what is within their practice and academic qualifications. Second, nurse practitioners are allowed to prescribe and dispense drugs as well as medical devices to their population of focus without supervision. This includes prescribing controlled substances, after obtaining DEA number and a prescribing authority from the Arizona Board of Nursing. However, they are not allowed to prescribe controlled substances for themselves or family members. Buy this excellently written paper or order a fresh one from ace-myhomework.com
