[{'content': 'Which of the following does not stimulate peripheral chemoreceptors? \nSelect and explain. \nA. Hypoxia, B. Hypocapnia, C. Acidosis, D. Low perfusion pressure', 'role': 'user'}, {'content': 'Answer: B \nExplanation: Hypercapnia is a stimulus not hypocapnia.\xa0\xa0\nLow perfusion produces hypoxia and hypercapnia at the level of chemoreceptors; thus\xa0stimulating them.\xa0\xa0\n\nPeripheral arterial chemoreceptors in the carotid and aortic bodies have very high rates of blood flow. These receptors are primarily activated by a reduction in partial pressure of oxygen (PaO2), but they also respond to an increase in the partial pressure of carbon dioxide (PaCO2) and pH.\xa0\nReference: Ganong’s Review of Medical Physiology T W E N T Y - F I F T H\xa0 \xa0E D I T I O N page no 593', 'role': 'assistant'}]
