NBRC Registered Respiratory Therapist - Exam Topics Sample Questions

One of the complications of mechanical ventilation  is pulmonary O2 toxicity. This is characterized by all but which of the following?

Correct Answer:
malnutrition


pulmonary oxygen toxicity is a condition that occurs when high concentrations of oxygen are administered for prolonged periods, typically through mechanical ventilation. in high doses, oxygen can become toxic to the lung tissues, leading to a range of pulmonary complications. the primary and direct effects of oxygen toxicity on the lungs include damage to the alveoli (air sacs in the lungs), leading to conditions such as edema, capillary congestion, and fibrosis.

edema in the context of pulmonary oxygen toxicity refers to the accumulation of fluid in the alveoli, which can impair gas exchange and reduce lung capacity. this fluid accumulation is a direct result of increased permeability of the alveolar-capillary barrier, a condition often exacerbated by prolonged exposure to high levels of oxygen.

capillary congestion is another common feature of pulmonary oxygen toxicity. this condition involves the swelling and engorgement of lung capillaries, which can further impair oxygen and carbon dioxide exchange across the alveolar-capillary membrane. the congestion of these capillaries can also contribute to the leakage of fluid into the alveoli, compounding the problem of edema.

fibrosis, or the thickening and scarring of lung tissue, is a severe and often irreversible consequence of chronic oxygen toxicity. fibrosis results from the prolonged inflammatory response triggered by high levels of oxygen, leading to the deposition of excess connective tissue. this fibrotic tissue can significantly reduce lung elasticity and function, making breathing more difficult and less effective.

contrary to the conditions mentioned above, malnutrition is not directly associated with pulmonary oxygen toxicity. malnutrition generally refers to the inadequate intake or absorption of nutrients and does not directly result from or contribute to the pulmonary effects of oxygen toxicity. while malnutrition can affect overall health and potentially exacerbate the effects of various illnesses, including lung conditions, it is not a characteristic effect of oxygen toxicity in the lungs. therefore, among the options provided, malnutrition is the correct answer as it is not a characteristic of pulmonary oxygen toxicity.
