A teenager living in a group home arrives at the emergency department combative and uncooperative. His legal guardians report that he has a history of overdosing with suicidal intent but has been doing well for almost 1 year. Two hours earlier he learned that his only living relative with whom he was very close (his maternal grandfather) had died in a car accident. About an hour after he received the news he was found crying in his bed with the following empty bottles lying around him: vodka, phenytoin, and aspirin.
What do these three substances have in common?
A.They all can cause profound hypoglycemia
B.They all can damage the kidneys
C.They all depress respiratory drive
D.They all readily saturate the enzymes that process them
E.They are all treated initially with activated charcoal

after done, u can try this one:
2. After a fire at a local family restaurant, several people are brought to the emergency department. A family reunion was taking place in one of the enclosed rooms, and even though the fire did not get into that room, several people were trapped there until the fire rescue squad was able to release them. Upon arrival these patients are lethargic, and a few of them complain of severe headaches and nausea. The patients are examined and blood is drawn for assessing carboxyhemoglobin levels.
Which of the following patients in the group should be the first candidate for hyperbaric oxygen therapy?
A.A 12-year-old girl who has a carboxyhemoglobin level of 25%, but has no external burns
B.A 30-year-old woman who is pregnant and has a carboxyhemoglobin level of 15%, but has no external burns
C.A 31-year-old man who is asymptomatic and has a carboxyhemoglobin level of 30%, but has no external burns
D.A 45-year-old man who is intubated with severe burns over 90% of his body
E.An 85-year-old woman with altered mental status who had a carboxyhemoglobin level of 10%, but has no external burns
