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.

People who have myopia, or nearsightedness, are not able to see objects at a distance but only up close. It occurs when the cornea is either curved too steeply, the eye is too long, or both. This condition is progressive and worsens with time. More than 100 million people in the United States are nearsighted, but only 20% of those are born with the condition. Diet, eye exercise, drug therapy, and corrective lenses can all help manage nearsightedness.
