Question

question 9 of 10
the goal for oxygen therapy in copd is to support tissue oxygenation, decrease the work of the cardiopulmonary system, and maintain the resting partial arterial pressure of oxygen (pao2) of at least ____ mm hg and an arterial oxygen saturation (sao2) of at least _%.
o 56 mm hg: 86%
o 54 mm hg: 84%
o 60 mm hg: 90%
o 58 mm hg: 88%

Explanation:

In oxygen therapy for COPD, the goal is to maintain a resting PaO₂ of at least 60 mm Hg and an SaO₂ of at least 90%. This is based on clinical guidelines for managing oxygenation in COPD patients to support tissue oxygenation and reduce cardiopulmonary workload.

Answer:

C. 60 mm Hg; 90% (assuming the option with 60 mm Hg and 90% is labeled as C, if the original options had labels, adjust the label as per the original. Here, since the options are presented as radio buttons, the correct one is the option with 60 mm Hg and 90%.)
