Concept explainers
a.
To compare: The concentration of H+ ions in the CSF as well as the blood plasma.
Introduction: Cerebrospinal fluid is a derivative of blood plasma and has great similarity with the blood plasma. The CSF and the blood plasma are formed continuously, but the major difference between the two fluids lies in the protein and electrolyte concentration.
b.
To determine: The concentration of Na+ ions in the CSF as well as the blood plasma
Introduction: Sodium ions are important cations that are present in the plasma as well as the CSF. The role of the sodium ions is to transport nutrients as well as waste material across the blood.
c.
To determine: The concentration of K+ ions in the CSF as well as the blood plasma
Introduction: Potassium ions are important cations that are present in the plasma as well as the CSF. The role of the potassium ions is to regulate fluid balance muscle contraction and nerve signals.

She recently returned from a trip to sub-Saharan Africa, where she did not take malaria prophylaxis. On examination, she is febrile (39.8°C/103.6°F) and hypotensive. Laboratory studies reveal hemoglobin of 8.0 g/dL, platelet count of 50,000/μL, and evidence of hemoglobinuria. A peripheral blood smear shows ring forms and banana-shaped gametocytes. Which of the following Plasmodium species is most likely responsible for her severe symptoms? A. Plasmodium vivax B. Plasmodium ovale C. Plasmodium malariae D.
