B.Because carbon monoxide binds the heme groups of hemoglobin, it is easily
removed or replaced by oxygen. As a result, the effects of oxygen deprivation
result in suffocation.
C.Because carbon monoxide binds tightly to the heme groups of hemoglobin, it is
not easily removed or replaced by oxygen. As a result, the effects of oxygen
deprivation result in suffocation.
D.None of the above
Pathophysiology

A.The patient suddenly develops shortness of breath
B.An asthmatic is starting to show signs of tiring
C.A diabetic has developed Kussmaul’s respirations
D.All of the above
Pharmacology
How do sulfa drugs selectively kill bacteria while causing no harm to humans?
A.Folic acid is a vitamin required for the synthesis of a coenzyme needed to make
the amino acid methionine and the purine and pyrimidine nitrogenious bases for
DNA and RNA and folic acid is produced by humans.
B.Sulfa drug binds to the enzyme, no product is formed, folic acid is made and the
biosynthesis of methionine and nitrogenous bases increases.
C.Humans are not harmed because they do not synthesize their own folic acid. It
is obtained in the diet.
D.None of the above
