Exhibits On day 3, the RN consults with the provider, who places an order for an arterial blood gas and serum lactate level. The ABG results are as follows: pH 7.35, pCO2 30, pO2 74, and HCO3 20. Based upon the results, what would the RN's most appropriate action be?

A. Instruct the client to take slow deep breaths: While slow deep breathing can help with minor respiratory issues, the ABG results indicate serious hypoxemia and metabolic acidosis. Oxygen support is the priority, not just deep breathing exercises. B. Ask the unit secretary to call a Code Blue: The ABG results show concerning findings but not an immediate life-threatening crisis that requires a Code Blue. Oxygen therapy should be the initial intervention to stabilize the patient. C. Reposition the client in low Fowler's position: Although positioning can sometimes help, the primary issue here is hypoxemia. Providing supplemental oxygen should be the first step before considering repositioning for comfort. D. Page the respiratory therapist to set up O2: The ABG shows hypoxemia (pO2 74) and metabolic acidosis (pH 7.35, HCO3 20). The immediate concern is to improve oxygenation, which can be managed by administering supplemental oxygen. Oxygen therapy will address both the low pO2 and help with compensatory acidosis.
