A client with diabetes receiving peritoneal dialysis experiences chills and abdominal discomfort. The nurse assesses the client's abdomen by pressing one hand firmly into the abdominal wall. The client experiences pain when the nurse quickly withdraws the hand. The client's most recent blood glucose level is 210 mg/dL (11.65 mmol/L). What is the priority action by the nurse?
1. Collect peritoneal fluid for culture and sensitivity
2. Heat the remaining dialysate fluid and increase the dwell time
3. Place the client in high Fowler's position
4. Prepare to administer regular insulin intravenously
