Final answer:
An indication of hemorrhage in a postpartum patient is the saturation of one perineal pad within an hour after birth, whereas an elevated pulse rate could be a compensatory response but is not as specific.
Step-by-step explanation:
The assessment finding that could indicate hemorrhage in the postpartum patient is b. Saturation of one perineal pad in the hour after birth. This sign may represent a significant blood loss, which requires immediate medical evaluation and intervention. In contrast, a firm fundus at the midline (a) is a normal finding and indicative that the uterus is contracting properly to reduce bleeding. An elevated blood pressure (c) can indicate other issues but is not a direct sign of hemorrhage. However, an elevated pulse rate (d) could be a compensatory mechanism for blood loss; in isolation, without considering other symptoms, it is not as specific as perineal pad saturation for diagnosing hemorrhage.
