Which of the following can be modified about an order without creating multiple rows in the MAR?

Modifying the end date/time of an order is significant because it does not necessitate the creation of multiple rows in the Medication Administration Record (MAR). When the end date or time is adjusted, it simply extends or shortens the duration for which the medication is prescribed, without altering the fundamental parameters of the order itself, such as dosage or drug formulation. This allows for clear and concise documentation within the MAR, as the original order remains intact, just with updated temporal specifications.

In contrast, changes to items such as medication dosage, form, or prescribing physician typically require creating new entries in the MAR. These modifications reflect significant changes to the medication order that necessitate clear tracking of different administration policies, thus leading to multiple rows to maintain clarity and accuracy in medication management and administration records.
