Question

A 24-year-old male with no significant past medical history is undergoing an elective open reduction and internal fixation of a right clavicle fracture. Induction of general anesthesia is achieved with propofol and succinylcholine, and anesthesia is maintained with sevoflurane. Thirty minutes into the procedure, the anesthesiologist notes a sudden and abrupt rise in the end-tidal carbon dioxide ($ETCO_2$) to $78\text{ mmHg}$. The patient develops generalized muscle rigidity, most notably in the masseter muscles. His core body temperature begins to rise rapidly and is currently $39.5^\circ\text{C}$ ($103.1^\circ\text{F}$). His heart rate is $152\text{/min}$, and blood pressure is $155/95\text{ mmHg}$.

Arrange the following management steps in the most appropriate chronological priority order for this patient's acute perioperative complication.
