Final answer:
The notation method that records only deviations from standard norms in medical record keeping is Charting by exception (CBE). It streamlines nursing documentation by recording only significant observations that fall outside of predefined norms.
Step-by-step explanation:
The medical record keeping method that requires notation only when the process deviates from norms is D) Charting by exception (CBE).
Charting by exception (CBE) is a streamlined documentation system that assumes certain standards of nursing practice and only requires nurses to document deviations from these norms or preset criteria. This method aims to reduce the amount of time that nurses spend on documentation and focuses on aberrations, which can indicate the occurrence of an event or the need for a change in the patient's care plan. It is important to note that SOAP notes involve the documentation of subjective and objective information, assessment, and plans, while Problem-oriented medical record (POMR) focuses on identifying and tracking a patient's problems over time. Narrative notes, on the other hand, provide a detailed chronological account of the patient's experience and care.
