A critically ill child has hyperthermia. The parents ask the nurse to give an antipyretic such as acetaminophen (Tylenol). The nurse should explain that antipyretics:
a. May cause malignant hyperthermia.
b. May cause febrile seizures.
c. Are of no value in treating hyperthermia.
d. Are of limited value in treating hyperthermia.
ANS: C
Unlike with fever, antipyretics are of no value in hyperthermia because the set point is already normal. Cooling measures are used instead. Malignant hyperthermia is a genetic myopathy that is triggered by anesthetic agents. Antipyretic agents do not have this effect. Antipyretics do not cause seizures and are of no value in hyperthermia.
