Dr. Smith, I'm calling about Mrs. P., your 65-year-old patient in CCU 10 . Her urine output for the past 2 hours totaled only 40 mL. She arrived from surgery to repair an aortic aneurysm 4 hours ago and remains on mechanical ventilation. In the past 2 hours, her heart rate has increased from 80 to 100 beats per minute and her blood pressure has decreased from 128/82 to 100/70 mm Hg. She is being given an infusion of normal saline at 100 mL per hour. Her right atrial pressure through the subclavian central line is low at 3 mm Hg. Her urine is concentrated. Her BUN and creatinine levels have been stable and in normal range. Her abdominal dressing is dry with no indication of bleeding. My assessment suggests that Mrs. P. is hypovolemic and I would like you to consider increasing her fluids or giving her a fluid challenge. Using the SBAR model for communication, the information the nurse gives about the patient's history and vital signs is: a. Situation b. Background c. Assessment d. Recommendation
