Final answer:
The PACU nurse should report the patient's vital signs, surgical drain outputs, condition of the incision site, level of consciousness, allergies, and recent lab results for thorough transfer of care.
Step-by-step explanation:
When the PACU nurse is reporting to the medical-surgical unit nurse, it is important to convey all relevant clinical information to ensure continuity of care. For the client who had an exploratory laparotomy, key facts provided included the status of the intravenous fluids, medication for nausea control, and pain management details. However, additional critical information should include the client’s vital signs, any surgical drain outputs, the state of the surgical incision site, the client's level of consciousness, any allergies the client might have, and the most recent laboratory results. This information would ensure that the medical-surgical unit nurse is fully apprised of the client’s condition and can continue to provide safe and effective care.
