To review:
Whether the following statements are true or false. False statements are to be corrected.
a. Potassium ions are responsible for the repolarization phase of the action potential.
b. Insulin, aldosterone, and epinephrine stimulate the uptake of potassium ions into cells.
c. Hyperkalemia tends to decrease the resting membrane potential and hyperpolarize excitable cells.
d. Hypocalcemia causes neurons to become hyperexcitable, leading to potential tetanic contractions.
e. Chloride ions are generally reabsorbed from the kidneys, along with bicarbonate ions.
Introduction:
The acids, body fluids, electrolytes, and bases playa role in the functioning of the human body. The major electrolytes in the human body are sodium, magnesium, calcium, potassium and chloride ions. The endocrine and the urinary systems of the body help in maintaining their balance in the body.

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. Plasmodium falciparumarrow_forward
