Oxygen therapy
Oxygen therapy ( 22 Questions)
At a flow rate of 4 L/min, oxygen therapy through a nasal cannula can increase the risk of oxygen toxicity, especially if used for prolonged periods. Oxygen toxicity can cause damage to the lungs and other organs.
Carbon dioxide retention is not a common complication at this flow rate. It may occur in patients with severe chronic obstructive pulmonary disease (COPD) at higher oxygen flow rates.
Nasal dryness is a common but relatively minor complication of oxygen therapy via nasal cannula. It can cause discomfort but is not a severe concern.
Fire hazard is not directly related to the use of a nasal cannula but rather to the use of oxygen in the presence of flammable materials or near open flames. It is a concern for all oxygen delivery devices, not specific to nasal cannulas.
Choice A rationale:
At a flow rate of 4 L/min, oxygen therapy through a nasal cannula can increase the risk of oxygen toxicity, especially if used for prolonged periods. Oxygen toxicity can cause damage to the lungs and other organs.
Choice B rationale:
Carbon dioxide retention is not a common complication at this flow rate. It may occur in patients with severe chronic obstructive pulmonary disease (COPD) at higher oxygen flow rates.
Choice C rationale:
Nasal dryness is a common but relatively minor complication of oxygen therapy via nasal cannula. It can cause discomfort but is not a severe concern.
Choice D rationale:
Fire hazard is not directly related to the use of a nasal cannula but rather to the use of oxygen in the presence of flammable materials or near open flames. It is a concern for all oxygen delivery devices, not specific to nasal cannulas.
