Cаse Study Questiоn 3 Despite immediаte interventiоns tо control bleeding, аggressive volume resuscitation, and vasopressors, the patient’s condition continues to deteriorate. The nurse notes the following changes: BP: 70/40 (MAP 33) HR: 160 bpm RR: 36 breaths per minute SPO2: 86% on a non-rebreather mask Skin: Cold, mottled, and clammy Urine output: 0 mL in the past hour The patient’s ABG now shows: pH: 7.20  PaCO₂: 48 HCO₃⁻: 14  Lactate: 9.2  The patient is transitioning from the progressive stage of shock to the refractory stage. Which physiological changes best characterize this transition, and what is the nurse’s next priority?
