Final answer:
The priority assessment for the PACU nurse is to assess the client's airway, breathing, and circulation. The priority diagnosis for the client in the postoperative period depends on the specific surgery and individual condition.
Step-by-step explanation:
The priority assessment for the PACU nurse on the client's admission to the PACU is to assess the client's airway, breathing, and circulation (ABC). This includes assessing the patient's oxygenation, respiratory effort, heart rate, blood pressure, and presence of any bleeding or signs of shock.
A thorough neurological assessment, including the client's level of consciousness, pupil response, and motor function, should also be conducted. The priority diagnosis for this client in the immediate postoperative period would depend on the specific surgery and the individual client's condition.
However, common priority diagnoses include pain, impaired gas exchange, risk for infection, and risk for fluid and electrolyte imbalance. These diagnoses should be based on the assessment findings and individual patient needs.
