Which manifestations would the nurse expect for a client with a history of malignant hyperthermia (MH)? Select all that apply.

Muscle rigidity is a hallmark sign of malignant hyperthermia. It commonly affects the muscles of the jaw and upper chest. Malignant hyperthermia can lead to rapid and shallow breathing, resulting in tachypnea. Malignant hyperthermia is characterized by a significant increase in body temperature, often exceeding 38.8°C (101.8°F). Malignant hyperthermia can cause irregular heart rhythms or dysrhythmias, including tachycardia or arrhythmias. The manifestations of hypertension and skin mottling are not typically associated with malignant hyperthermia. Hypertension (high blood pressure) is more commonly seen in conditions such as hypertensive emergencies or certain cardiovascular disorders. Skin mottling, which refers to irregular or patchy skin coloration, is not a specific manifestation of malignant hyperthermia.
