Which of the following statements are correct with regards to sulfamethoxazole/trimethoprim?
a. it is a potent hepatic enzyme inducer resulting in reduced drug concentrations.
b. it has excellent bioavailability, thus can transition from intravenous to oral formulations in a 1: 1 fashion.
c. it is active against many gram-positive pathogens, including staphylococci, gram-negative pathogens, and opportunistic pathogens.
d. this drug should be used with caution in a patient with g6pd deficiency.
e. a negative coombs test with sulfamethoxazole/trimethoprim indicates hemolytic anemia

The following statements are correct with regards to sulfamethoxazole/trimethoprim

B.) It has excellent bioavailability, thus can transition from intravenous to oral formulations in a 1:1 fashion.

C.) It is active against many Gram-positive pathogens, including Staphylococci, Gram-negative pathogens, and opportunistic pathogens.

D.) This drug should be used with caution in a patient with G6PD deficiency.

Explanation:

sulfamethoxazole/trimethoprim is an antibiotic used for the treatment of many bacterial infections. It consists of one part trimethoprim to five parts sulfamethoxazole and therefore is also called co-trimoxazole.

A positive Coombs test with sulfamethoxazole/trimethoprim indicates hemolytic anemia therefore should be discontinued. It is a potent hepatic enzyme inhibitor ( not inducer).

answer; i believe that the correct answer is ; males are hemizygous for the x chromosome;

white blood cells or wbc s are mainly 2 types-

1.agranulocytes

2.granulocytes

the monocytes or macrophages of agranulocytes , dendritic cells which are accessory leucocytes, and b cells which is one type of lymphocytes   identify the antigens present on the pathogen's surface. these three cells are called antigen presenting cells(apc) which are phagocytes and destroy the antigens by secreting antitoxins. besides this leukocyte is always plays vital role in the immunity of the body.
