The respiratory therapist is evaluating a patient in the intensive care unit who shows signs of tissue hypoxia. Laboratory results reveal the following: HgB 14.8 grams, CaO2 19.6 vol.%, PaO2 102 mm Hg, a-v difference 9.8 vol.%, PvO2 24 mm Hg. Based on these results, which of the following types of hypoxia does this patient have?

A) Hypoxic hypoxia B) Anemic hypoxia C) Circulatory hypoxia D) Histotoxic hypoxia A) Hypoxic hypoxia B) Anemic hypoxia C) Circulatory hypoxia D) Histotoxic hypoxia

A patient has been exposed to smoke during a house fire. An ABG result shows a normal PaO2. How should the patient's PaO2 value be interpreted?

A) The PaO2 is being falsely elevated by the carbon monoxide. B) The PaO2 is being falsely decreased by the carbon monoxide. C) The PaO2 is accurate. D) The PaO2 is a false measurement because the presence of carbon monoxide makes the analyzer unable to determine the PaO2. A) The PaO2 is being falsely elevated by the carbon monoxide. B) The PaO2 is being falsely decreased by the carbon monoxide. C) The PaO2 is accurate. D) The PaO2 is a false measurement because the presence of carbon monoxide makes the analyzer unable to determine the PaO2.
