Which change in the anesthetized client alerts the nurse to the possibility of malignant hyperthermia?
A. Widened pulse pressure
B. Increased output of dilute urine
C. Increased end tidal carbon dioxide level
D. Ascending flaccid paralysis of skeletal muscles
C
The carbon dioxide level of expired (exhaled) air is an indication of acid-base balance. With ma-lignant hyperthermia, the metabolism of skeletal muscles is greatly increased, generating extreme heat and causing an oxygen debt. This condition leads to lactic acidosis and increased production of carbon dioxide. A rise in the end tidal carbon dioxide level is the most sensitive indicator of the presence of malignant hyperthermia. A rise in body temperature is a late sign.
