Correct answer: Measures to prevent drug dispensing errors: In order to prevent and reduce drug dispensing errors, it is necessary to implement preventive measures in all links and implement quality control in the whole process of drug dispensing. Environmental facilities: (1) Dispensing area and dispensing area are relatively separated to avoid external noise disturbing pharmacists. (2) The lighting is bright, and the illumination in the mixing room is not less than 20001x.. (3) Intelligent dispensing equipment and information technology are effective measures to reduce dispensing errors. Placement and storage of drugs: (1) The placement of drugs should help to reduce dispensing errors and improve dispensing efficiency, and can be placed and stored in the form of location codes according to the frequency of use, route of administration or pharmacological action. (2) Only trained and authorized personnel can replenish drugs on the drug rack, so as to ensure strict correspondence with the labels on the drug rack (marked with generic names, trade names and specifications of drugs). (3) Drugs of the same variety and different specifications should be placed separately. (4) Drugs with similar packaging or similar pronunciation should be placed separately. High-warning drugs should be placed centrally, and marked warning labels should be attached for pharmacists to pay attention to when dispensing (see "Recommended Labels for High-warning Drugs and LASA Drugs" published on the website of Hospital Pharmacy Committee of Chinese Pharmaceutical Association). Strengthen prescription review and deployment, drug dispensing verification and drug description. Other measures: (1) Formulate standard deployment operation procedures, which will help the staff to implement them in their work. (2) When the types, dosage forms, specifications and packaging of drugs change, let the staff know in time. (3) It is necessary to maintain the appropriate work intensity of pharmacists, appropriately increase deployment personnel during peak hours, and reduce deployment errors caused by fatigue. Pharmacists should also pay attention to medication errors in the process of non-drug dispensing, such as doctors' prescription errors, nurses' medication errors and patients' medication errors. We should prevent and reduce medication errors through consultation, training, medication guidance and information technology.
