Rationale: The most appropriate oxygen delivery device for a patient with chronic respiratory failure secondary to severe restrictive lung disease requiring continuous supplemental oxygen is a non-rebreather mask. A non-rebreather mask is designed to deliver high-flow oxygen and is typically used for short-term medical treatment in emergency situations or for critically ill patients. It is ideal for providing the highest concentration of oxygen available for inhalation, making it suitable for patients with severe hypoxemia.

Specifically, the presence of intraerythrocytic ring forms and trophozoites on blood smear examination points towards Plasmodium falciparum as the most likely causative agent. Plasmodium falciparum is the most deadly of the Plasmodium species that cause malaria and is responsible for the majority of severe malaria cases worldwide. It is transmitted through the bite of infected Anopheles mosquitoes. Treatment for Plasmodium falciparum infection usually involves antimalarial medications such as artemisinin-based combination therapies.

Edema is characterized by the accumulation of excess fluid in the body's tissues, leading to swelling.

It is crucial to identify and address the underlying cause of edema promptly to prevent complications and provide appropriate treatment for the patient.
