If a patient post-CABG has 100 ml of dark blood in their chest tubes after being turned, what should the nurse do?

Monitoring vital signs and observing for further drainage is the appropriate course of action when a patient post-CABG has dark blood in their chest tubes after being turned. Dark blood can indicate venous blood or the possibility of bleeding from the surgical site. By evaluating vital signs, the nurse can detect any hemodynamic instability or signs of worsening condition, such as a drop in blood pressure or an increase in heart rate, which may require more immediate intervention.

Additionally, observing for further drainage helps to assess whether the initial 100 ml is a one-time occurrence or part of a larger trend that could indicate complications, such as a hematoma formation or bleeding. Early identification and monitoring of these signs are critical in post-operative care as they can impact the patient's recovery and overall outcomes.

Ignoring this drainage would not be appropriate as it may mask underlying complications that could be life-threatening. Notifying the surgical team without additional assessment could lead to unnecessary alarm if the drainage is within acceptable limits and not accompanied by other concerning signs. Administering a fluid bolus might be warranted if vital signs indicate hypovolemia or instability, but it is essential first to evaluate the patient's overall condition before proceeding with fluid resuscitation.
