Pyrimethamine (Daraprim) has been ordered for the patient as prophylactic treatment of malaria. The nurse recognizes the action of this drug prevents relapse of the disease by acting on what?
A) Changing the metabolic pathways for reproduction
B) Disrupting the mitochondria of the plasmodium
C) Blocking the use of folic acid
D) Increasing the acidity of plasmodial food vacuoles
C
Feedback:
Pyrimethamine is used in combination with agents that act more rapidly to suppress malaria; it acts by blockings the use of folic acid in protein synthesis by the plasmodium, eventually leading to inability to reproduce and cell death. Chloroquine changes the metabolic pathways for reproduction of the plasmodium and is toxic to parasites that absorb it. Primaquine disrupts the mitochondria of the plasmodium. Mefloquine increases the acidity of plasmodial food vacuoles causing cell rupture and death.
