A 65-year-old man with essential hypertension well controlled around 140/90 mmHg with hydrochlorothiazide is scheduled for right colectomy for carcinoma. Preoperative EKG and all laboratory values are normal except for a hematocrit of 29% and serum potassium level of 3.2 mEq/L. Central venous pressure (CVP) measured from an internal jugular catheter inserted before induction of anesthesia is 7 mmHg. Ten minutes after induction with thiopental 200 mg followed by enflurane 3% in nitrous oxide and oxygen (50% each), blood pressure decreases suddenly from 110/70 to 80/50 mmHg with heart rate unchanged at 78 bpm. CVP is now 20 mmHg and the EKG demonstrates a midjunctional rhythm. After discontinuing the enflurane, the most appropriate action would be to
