Unjustified retention or prevention of the movement of another person without proper consent can constitute | false imprisonment. |
Disclosure of confidential information, such as inappropriately discussing a patient’s problem with a third party, may be construed as | invasion of privacy |
designed to protect health practitioners when they give aid to people in emergency situations. | Good Samaritan laws |
person’s agreement to allow something to happen, such as surgery, based on a full disclosure of risks, benefits, alternatives, and consequences of refusal. | Informed consent |
Nurses are legally responsible for carrying out the orders of the physician in charge of a patient unless | a reasonable person would anticipate the order to lead to injury. |
used by health care agencies to document the occurrence of anything out of the ordinary that results in, or has the potential to result in, harm to a patient, employee, or visitor | incident report (also called a variance or occurrence report) |
The nurse responsible for a potential or actual harmful incident or who witnesses an injury is the one who completes the | incident form |
disclosure of confidential information, such as inappropriately discussing a patient’s problem with a third party, may be construed as | invasion of privacy and may subject the nurse to liability. |
