A) "It has been shown that oxygen given to a patient with an acceptable pulse oximetry reading can be harmful."
B) "That may have been an oversight, given that chest pain is caused by a lack of oxygen-rich blood delivery through the coronary arteries."
C) "Since extra oxygen slows the respiratory rate, it also causes the body to retain CO2, which is not beneficial for heart patients."
D) "If the patient also had a history of COPD, oxygen was most likely withheld since it would be contraindicated."
