The ANA Standards of Practice, also known as the Nursing Process which informs decision-making, has 6 standards of practice. Identify the 6 standards fully and in order (1 point each) and walk through a clinical scenario of how you carried out each step to make a clinical decision for one of your patients (1 point each) using the standards of the nursing process.
