A hospital patient is complaining of increased shortness of breath. The nurse observes a respiratory rate of 24 on 3 liters per minute (LPM) of oxygen via nasal cannula. Which of the following actions should be done initially?

Conduct a comprehensive respiratory assessment.


•The nurse should first assess the patient's respiratory system to identify abnormalities to report.

•The nurse may increase the oxygen flow rate if the patient is not maintaining an oxygen saturation above 90%, but should notify the physician of the increased oxygen requirements.

•The physician should be notified after the nurse has obtained complete assessment data and attempted all available nursing and pharmacological interventions.

•Administer a bronchodilator if airway obstruction or narrowing is suspected based upon the findings of the respiratory assessment, which would be done first.
