Correct answer: D. Pyrimethamine + Sulfadoxime
- A. Atovaquone + Proguanil
- B. Artemisinin
- C. Quinine + Tetracycline
- D. Pyrimethamine + Sulfadoxime
Explanation
Pyrimethamine with sulfadoxine was classically administered as a single-dose treatment for malaria, although it does not provide radical cure of P. vivax because dormant liver hypnozoites require primaquine. The other regimens listed require multiple doses or are not suitable single-dose therapy.
