Which of the following is a common sequale of electric injury?
a. Cardiac damage, such as myocardial confusion or infarction, may be present.
b. More likely, the conduction system may be deranged.
c. Household current at 110 V either does no damage or induces ventricular fibrillation.
d. If there are no electrocardiographic rhythm abnormalities present upon initial emergency department evaluation, the likelihood that they will appear later is minuscule.
e. Even with high voltage injuries, a normal cardiac rhythm on admission generally means that subsequent dysrhythmia is unlikely.
f. Cataracts are a well-recognized sequela of high – voltage electric burn.
g. The electrical resistance of the skin depends upon the moisture, cleanliness and thickness.
h. The average resistance of the skin is 40000ohms.
