Answer to Question 1

ANS: D
DIC is a life-threatening syndrome. It is caused by a malfunction within platelet aggregation and clotting. The normal clotting mechanisms do not work. It is an over action of clotting and breakdown, which leads to platelet consumption and coagulation factors. This acts as a potent anticoagulant leading to hemorrhage and many other problems.

Answer to Question 2

ANS: C
Malignant hyperthermia (MH) is a hypermetabolic crisis in susceptible people. It is triggered by potent halogenated anesthetic agents and depolarizing skeletal muscle relaxants. Susceptible patients also include those with any type of myopathy or acquired muscle disease, such as ptosis, strabismus, hernia, muscle weakness or hypertrophy, or muscular dystrophy. The incidence of MH is higher in children than in adults. Patients, especially children, with rheumatoid arthritis are particularly susceptible to MH.
