Nurses must carefully maintain patient medical records to avoid legal issues. Records should be kept securely under nurse custody, without separating individual sheets. Confidential patient information must be protected and records not made accessible to unauthorized people. Records should include identifying patient information and any alterations or copies must be clearly indicated, following facility policies. Proper documentation principles like date, time, legibility, and accuracy should be followed. Computerized records also require maintaining confidentiality, not disclosing passwords, and not deleting information without authorization.
