Frоm scenаriо #7. Fоr questions 7-10: Scenаrio: A postmenopаusal woman, is admitted to the critical care unit after emergency surgery for treatment of a perforated bowel. Intraoperatively, she had an estimated blood loss of 400 mL, and she received 2500 mL of crystalloid solution. An arterial line, subclavian triple-lumen catheter, and indwelling urinary catheter are placed while in the surgical unit. Upon admission to the critical care unit, the client is intubated and sedated. She is placed on mechanical ventilation with the following settings: assist/control mode at 12 breaths per minute; Her initial postoperative vital signs and laboratory findings are: Heart rate 140 beats/min. Blood pressure 88/49 mm Hg Mean arterial pressure 62 mm Hg Respiratory rate 12 breaths/min. Right atrial pressure (central venous pressure) 4 mm Hg Temperature 39.2° C (102.6° F) Peak inspiratory pressure (PIP) 27 cm H2O Lactate 1.1 mEq/L The physician orders a 500-mL infusion of normal saline (NS) 0.9%, repeat of serum lactate level, and replacement of the triple-lumen catheter with a catheter that measures central venous oxygen saturation (ScvO2). The nurse administers the fluids and assists with the placement of the ScvO2 catheter. After these interventions, the nurse reassesses vital signs and hemodynamic values, which are noted below: Heart rate 118 beats/min Blood pressure 96/52 mm Hg Mean arterial pressure 66 mm Hg Right atrial pressure (central venous pressure) 8 mm Hg Cardiac index (CI) 2.8 L/min/m2 ScvO2 59% Lactate 3.6 mEq/L For this client what is the most likely cause of a decreased ScvO2 value?
