I am presuming that this is a NCLEX test question... your priority nursing intervention is 2-3 L/M O2 via NC.
One of the above posters is correct that O2 is a drug, which requires a physicians order to administer. However (in the realm of the NCLEX) if you selected notify the physician (to obtain an order), you would get this question wrong as you are delaying care.
Additionally, you must auscultate the patient to ensure that adequate ventilation is present.
COPD pt's will tend to run on the HTN side of the house due to chronic arteriolar vasoconstriction, along with concurrent pulmonary HTN.
