单项选择题

Broken Bones: Do not move the patient. Send for ambulance at once. Treat for shock if necessary.
Bleeding: A little bleeding does not harm. It washes the dirt from the wound. But if the bleeding continues, try to stop it by placing a clean cloth (the inside of a folded handkerchief, for example) firmly over the wound until the bleeding stops or until help arrives.
If the wound is a small one and made by something clean, wash it carefully with soap and water. Then bend it firmly but not too tightly. A large wound, or a dirty one, should be treated by a doctor.
Poison: A person who has swallowed poison should be taken to a hospital at once. With some poisons and sleeping pills, for example, it is a good thing to make a patient sick by pushing your finger down to his throat. But if he swallowed some kind of acid, anything that burns, it would be a bad thing to make him sick. The poison would burn his throat as it came up. It is therefore, the best to take the patient to hospital at once. But try to find out what the patient has taken so that you can tell the doctor.

The word "sick" in the passage means feeling______.

A. unhappy to say what one knows
B. sad to eat something bad
C. unpleasant to throw up what is in the stomach
D. difficult to do something important
