The nurse is caring for a patient with a pulmonary artery catheter.Assessment findings include a blood pressure of 85/40 mm Hg,heart rate of 125 beats/min,respiratory rate 35 breaths/min,and arterial oxygen saturation (SpO₂)of 90% on a 50% Venturi mask.Hemodynamic values include a cardiac output (CO)of 1.0 L/min,central venous pressure (CVP)of 1 mm Hg,and a pulmonary artery occlusion pressure (PAOP)of 3 mm Hg.The nurse questions which of the following physician's orders? A) Titrate supplemental oxygen to achieve a SpO₂ $\geq$94%. B) Infuse 500 mL 0.9% normal saline over 1 hour. C) Obtain arterial blood gas and serum electrolytes. D) Administer furosemide (Lasix) 20 mg intravenously.

A central venous pressure of 1 mm Hg,pulmonary artery occlusion pressure of 3 mm Hg along with a blood pressure of 85/40 mm Hg and heart rate of 125 are indicative of a low volume state.Infusion of 500 mL of 0.9% normal saline will increase circulating fluid volume.Administration of furosemide (Lasix)is contraindicated and could further reduce circulating fluid volume.Titrating supplemental oxygen and obtaining serum blood gas and electrolyte samples,although not a priority,are appropriate interventions.
