When monitoring a client's abdominal incision, the practical nurse (PN) observes a large amount of sanguineous drainage on the dressing. Which client data collection should the PN complete first?

A. Blood pressure: A large amount of sanguineous drainage may indicate active bleeding. Assessing blood pressure first helps determine if the client is becoming hemodynamically unstable, as hypotension can signal significant blood loss requiring immediate intervention. B. Temperature: Monitoring temperature is important for detecting infection, but it is not the immediate concern when active bleeding is suspected. Infection develops over time, whereas hemorrhage poses an immediate risk to life. C. Pain scale: Assessing pain is part of routine postoperative care, but it does not provide critical information about potential blood loss or circulatory compromise, which must be addressed first. D. Bowel sounds: Checking bowel sounds evaluates gastrointestinal recovery, which is not a priority when there is evidence of possible hemorrhage. Assessing vital signs, especially blood pressure, takes precedence in identifying acute complications.
