Which abbreviation indicates that a medication should be given immediately?

The abbreviation that indicates a medication should be given immediately is "STAT." This term is derived from the Latin word "statim," meaning "immediately." It is commonly used in medical settings to signify urgency, prompting healthcare providers to prioritize the administration of the medication as soon as possible, typically in emergency situations or when a patient’s condition requires prompt action.

In contrast, other options are used in different contexts. "VO" stands for "verbal order," which refers to a medication order given verbally by a physician, and does not indicate urgency. "PRN," meaning "as needed," designates medications that are administered only when necessary, not necessarily immediately. "BID" signifies that a medication should be taken twice a day, which indicates a scheduled timing rather than immediate administration. Recognizing these distinctions is critical for proper medication management and patient care.
