Final answer:
The best option for a patient with malignant hyperthermia is to avoid triggering factors and receive prompt medical treatment with dantrolene sodium if symptoms occur.
Step-by-step explanation:
If a patient is known to have malignant hyperthermia, the best option is to avoid triggering factors that can lead to a hypermetabolic crisis. Malignant hyperthermia is a rare, inherited condition characterized by a severe reaction to certain medications used during anesthesia. The onset of symptoms can include hyperthermia, muscle rigidity, and an increased heart rate. Prompt recognition and treatment with dantrolene sodium, a muscle relaxant, is crucial to prevent complications.
