How would you respond if he asks you for help?
A) "Administer 2 liters per minute by nasal cannula to all patients with suspected pulmonary embolism." B) "Administer supplemental oxygen to the patient of sufficient amount to maintain the pulse oximeter reading at or greater than 94%." C) "Since a pulmonary embolism is a vascular problem rather than lung problem, administer oxygen to maintain a pulse oximeter reading of greater than 95%."
