Which of the following describes a standing order in a healthcare setting?

A standing order in a healthcare setting refers to a set of pre-established instructions that allow healthcare professionals to administer specific treatments or medications without requiring a new physician's order each time. These orders are typically designed to be followed in routine situations, thus streamlining care for patients.

The option that accurately describes a standing order is "Regular diet." This indicates a general guideline for patient care that can be applied to multiple patients under similar circumstances. The standing order for a regular diet allows healthcare staff to initiate this dietary plan without needing to consult a physician each time, supporting efficiency in patient management and nutritional care.

In contrast, the other options involve more specific interventions that are typically not standardized for all patients. For instance, "Tylenol 500 mg PO q4-6h for H/A" specifies treatment for a headache, which is not applicable to all patients universally, making it a specific medication directive rather than a standing order. "IV fluids as needed" implies a decision based on individual patient assessment and condition rather than a predetermined order. Lastly, "Antibiotic until infection resolves" involves a dynamic treatment plan that requires continuous evaluation and is not a general protocol that can be universally applied to all patients.
