Answer to Question 1

A
Feedback:
African sleeping sickness, which is caused by Trypanosoma brucei gambiense, is transmitted by the tsetse fly. After the pathogenic organism has lived and grown in human blood, it eventually invades the central nervous system, leading to acute inflammation resulting in lethargy, prolonged sleep, and even death. G. lamblia causes giardiasis; T. cruzi causes Chagas' disease. A promastigote is a flagellated protozoan that causes leishmaniasis.

Answer to Question 2

A
Feedback:
Fosfomycin would be a good choice for this patient because it has the convenience of a single dose. Methenamine is taken either twice a day or up to four times a day. This drug could interfere with the patient's busy schedule. Nitrofurantoin is also prescribed four times a day and would also be inconvenient for the patient. Norfloxacin is taken every 12 hours and could be inconvenient as well.
