During change-of-shift report on a medical unit, a client admitted with aspiration pneumonia and respiratory distress has become increasingly agitated. Which action should the nurse take first?

Choice A reason: Notifying the provider is important but not the first action. Agitation in aspiration pneumonia may stem from hypoxemia, a life-threatening issue. The ABCDE approach prioritizes assessing breathing (oxygen saturation) to identify and correct hypoxemia before escalating to the provider, ensuring immediate intervention for a potentially reversible cause. Choice B reason: Administering a PRN sedative may reduce agitation but risks masking underlying causes like hypoxemia, common in aspiration pneumonia. Sedatives can depress respiration, worsening hypoxia. The ABCDE approach prioritizes assessing oxygen status first to address life-threatening causes of agitation, making sedation a secondary consideration after evaluation. Choice C reason: Agitation in aspiration pneumonia often results from hypoxemia due to alveolar inflammation and impaired gas exchange. Using pulse oximetry to check oxygen saturation is the first action in the ABCDE approach, as it assesses breathing and identifies hypoxia, a life-threatening condition requiring immediate oxygen therapy or ventilatory support to stabilize the client. Choice D reason: Offering reassurance and reorientation addresses agitation’s psychological aspects but does not treat underlying physiological causes like hypoxemia. In aspiration pneumonia, agitation is likely due to low oxygen levels, which must be assessed first via pulse oximetry. The ABCDE approach prioritizes breathing over non-physiological interventions in acute respiratory distress.
