The nurse is caring for a patient in the operating suite who is experiencing hypercarbia, tachypnea, tachycardia, premature ventricular contractions, and muscle rigidity. Which condition does the nurse suspect the patient is experiencing?

A) Malignant hyperthermia
B) Fluid imbalance
C) Hemorrhage
D) Hypoxia

A life-threatening, rare complication of anesthesia is malignant hyperthermia. Malignant hyperthermia causes hypercarbia, tachycardia, tachypnea, premature ventricular contractions, unstable blood pressure, cyanosis, skin mottling, and muscular rigidity. It often occurs during anesthesia induction. Hypoxia would manifest with decreased oxygen saturation as one of its signs and symptoms. Fluid imbalance would be assessed with intake and output and can manifest with tachycardia and blood pressure fluctuations but does not have muscle rigidity. Hemorrhage can manifest with tachycardia and decreased blood pressure, along with a thready pulse. Usually some sign or symptom of blood loss is noted (e.g., drains, incision, orifice, and abdomen).
