Description

Which of the arterial blood gases indicates a compensated respiratory acidosis? pH 7.36, PaCO2 55, HCO3 30 Metabolic acidosis is evident on an arterial blood gas sample when both pH & bicarbonate ion are lower than normal. True Diarrhea & other lower intestinal fluid losses will contribute to metabolic acidosis A patient with respiratory acidosis can correct for the disorder by hyperventilating true Neutral pH for the human body is 7.4 Vomiting of stomach contents or continuous nasogastric suctioning may predispose to development of Metabolic acid deficit Buffer systems, exhaling carbon dioxide an expression by the kidneys are all ways to eliminate H+ from the body The normal ratio of bicarbonate to carbonic acid in blood is 10:1 false A person who chronically hypoventilate will have a higher than normal concentrations of bicarbonate in the blood true Loss of upper GI contents(vomiting) may lead to metabolic acidosis, whereas loss of the lower GI contents(diarrhea) may lead to metabolic acid deficit false The body compensate for metabolic alkalosis by hypoventilation A student is nervous for a big exam and is breathing rapidly. Which of the following might occur? respiratory alkalosis A 57 year old male with COPD, home oxygen dependence, and daily chronic sputum production is created with several types of metered dose inhaler. No other medications. He is in his usual state. Which of the following is the most likely acid base disorder to be present? chronic respiratory acidosis Classify the following arterial blood gas semicolon pH = 7.19 PaCO2 = 49, mm Hg, HCO3 = 24 mEq/L respiratory acidosis Two important renal buffers are NH3 & HPO4 The kidneys are able to convert co2 and water to bicarbonate and hydrogen ions true For a person with the following blood gas measurements, what would be a compensatory response: pH = 7.2, PaCO2 = 40 mm Hg, HCO3 = 18 mEq/L hyperventilation The finding of ketones in the urine suggests that a person may have which of the following acid-base disorders? Metabolic acidosis The enzyme that catalyzes the conversion of carbonic acid into co2 + h2o and vice versa is carbonic an...
