A nurse has taken a telephone order which must be countersigned with the original signature of the physician within ______ days of receipt of the order.

The requirement for a physician's signature on a telephone order emphasizes the need for accountability and proper documentation in patient care. In Pennsylvania, the regulation clearly states that a physician must countersign a telephone order within 48 hours of the order being received. This ensures that there is a timely review of the orders to verify accuracy and appropriateness, which is critical for patient safety and continuity of care. The 48-hour timeframe serves to maintain a balance between prompt medical attention and the necessity of physician oversight, allowing for the swift initiation of necessary treatments while ensuring accountability in the medical decision-making process. This standard is in place to prevent any potential delays in care that could arise from unsigned orders.
