Oxygen Therapy Practice Exam

In the context of oxygen therapy, complications can arise from its use, but increased pulmonary blood pressure is not typically recognized as a direct complication associated with oxygen therapy. Oxygen toxicity, dehydration of mucous membranes, and the risk of fire hazard are well-established concerns.

Oxygen toxicity occurs due to the harmful effects of excessive oxygen concentration, potentially leading to lung damage and other systemic effects. Dehydration of mucous membranes can result from high concentrations of oxygen, especially when delivered through devices that dry out the airways. The risk of fire hazard is a critical safety issue, as oxygen supports combustion and increases the risk of fire in environments where flammable materials are present.

In contrast, increased pulmonary blood pressure is more commonly associated with conditions like pulmonary hypertension, rather than a direct consequence of oxygen therapy. Thus, this condition does not align with the known complications of oxygen therapy and stands out as an exception.
