Final answer:
Increased blood pressure and decreased urine output would require intervention by the nurse during a second exchange of intermittent PD.
Step-by-step explanation:
A 69 year old client undergoing intermittent peritoneal dialysis (PD) may experience various signs and symptoms that require nursing intervention. In this case, the nurse should intervene if the client has increased blood pressure and decreased urine output. Increased blood pressure may indicate issues with fluid overload, while decreased urine output may suggest that the PD is not adequately removing waste products from the body. On the other hand, improved appetite and decreased abdominal pain are positive outcomes that do not require immediate intervention.
