Mr. J is a 44-year-old man with no previous medical history who presents to the emergency department with a chief complaint of severe abdominal pain, fever, and chills. He is subsequently admitted to the critical care unit after an open exploratory laparotomy where it was found that he had a perforated appendix and diffuse peritonitis. Intraoperatively, he had an estimated blood loss of 350 mL, and he received 1 liter of crystalloid solution in the OR. He arrives at the critical care unit intubated and sedated with a right radial arterial line, a five-lumen pulmonary artery catheter, and an indwelling urinary catheter in place.
CASE SCENARIO QUESTIONS:
1. The charge nurse and CCU nurse receiving the patient from the OR team had just finished getting the patient settled. The CCU nurse performs her admission assessment and documents vital signs and pressure. Before she records his arterial, pulmonary artery pressure, and right atrial pressure readings, what should she do first? Why?
