Step-by-step explanation:
EHR systems support nurses in making beneficial healthcare decisions. EHR stands for Electronic Health Record, which is a digital version of a patient's medical history, including diagnoses, medications, and lab results. The EHR system provides nurses with access to this information in real-time, allowing them to make informed decisions about patient care. For example, if a nurse needs to check a patient's allergies before administering medication, they can quickly look it up in the EHR system.
