Legal analysis: 1. Medical orders are issued by doctors. When nurses implement medical orders, they should follow the principles of timeliness, accuracy, seriousness and completeness, and strictly implement the verification system.

2. Medical orders must be signed by a licensed physician before they are valid. Under normal circumstances, doctors are not allowed to issue oral medical orders. When oral medical orders need to be issued to rescue critical patients, the executing nurse must repeat them again. Only after both parties confirm that they are correct can they be executed, and the ampoule should be retained for reconfirmation. After the rescue, the doctor should make up the actual medical instructions within 6 hours.

Legal basis: Article 502 of the "People's Republic of China and Civil Code" A contract established in accordance with the law shall take effect from the time of its establishment, unless otherwise provided by law or otherwise agreed by the parties.

In accordance with the provisions of laws and administrative regulations, if the contract should be approved and other procedures should be followed, the provisions shall be followed. If the failure to go through approval and other procedures affects the effectiveness of the contract, it will not affect the effectiveness of the contract's obligations such as reporting for approval and the effectiveness of related clauses. If the party that should go through the application approval and other procedures fails to perform its obligations, the other party may request that it bear liability for violating such obligations.

In accordance with the provisions of laws and administrative regulations, if the modification, transfer, termination, etc. of a contract require approval and other procedures, the provisions of the preceding paragraph shall apply.
