PRN: Long-term medical advice when necessary

Doctor's advice is the doctor's instructions for the patient's diet, medication, laboratory tests, etc. based on the patient's condition and treatment needs. Medical orders refer to medical instructions issued by physicians in medical activities. The content of the medical order and the start and stop times should be written by the physician. The contents of medical orders should be accurate and clear. Each medical order should contain only one content and indicate the time of issuance, which should be specific to the minute. It is divided into three categories: long-term medical orders, temporary medical orders and backup medical orders.

Extended information:

Doctor's orders refer to the medical instructions issued by the physician during medical activities. The physician collects a detailed medical history, carefully conducts a physical examination, and conducts necessary imaging and laboratory examinations in a timely manner. Record the first course of illness and write medical records, and issue medical orders after making a preliminary diagnosis. Medical instructions include: nursing routine, level of care, diet type, body position, various examinations and treatments, drug names, dosages and usage. The content of the medical order and the start and stop times should be written by the physician.

The contents of medical orders should be accurate and clear. Each medical order should contain only one content and indicate the time of issuance, which should be specific to the minute. Doctor's orders may not be altered. When cancellation is required, the word "Cancel" should be marked in red ink and signed. Generally, physicians are not allowed to give oral medical orders. When oral medical orders need to be given to rescue critical patients, the nurse should repeat them. After the rescue, the doctor should immediately write down the medical instructions according to the actual situation. Medical orders are divided into long-term medical orders and temporary medical orders. The content of the long-term medical order includes the patient's name, department, hospitalization record number (or medical record number), page number, start date and time, content of the long-term medical order, stop date and time, physician's signature, execution time, and execution nurse's signature.

The contents of the temporary medical order include the time of the medical order, the content of the temporary medical order, the physician's signature, the execution time, the execution nurse's signature, etc.

Other medical terms

CR (Computed Radiography) can be translated as computerized radiography or digital radiography. The digitization of CR replaces film and intensifying screens with an imaging plate (IP plate) that can be read repeatedly. After exposure, a latent image is generated on the IP board. The IP board is placed in the CR scanner, the IP board is scanned with a laser beam, the information is read, and a digital image is generated after analog/digital conversion.

CR MR CT DR DSA X-ray is a type of medical imaging disease diagnosis. MRI is a magnetic resonance imaging examination that can obtain cross-sectional, sagittal and coronal images. Good spatial resolution. CT is an X-ray diagnostic device, a complex X-ray device that can obtain cross-sectional images. Compared with MRI, its characteristic is high density resolution. CR, DR and X-ray diagnosis, like CT, also use X-rays to complete images. The difference is that CR and DR are more advanced in image acquisition than ordinary X-ray machines. CR is an IP board, and DR is more advanced and directly transmits digital information to the imaging workstation through a flat-panel detector. Simply put, there is no significant difference in the scope of their diagnoses.
