The nurse is assessing a patient's nostrils for patency. How should the nurse best perform this assessment?

A. Insert a nasal tube into each nostril to ensure no blockage is present: Inserting a nasal tube is an invasive procedure that is not necessary for assessing nostril patency. This method can cause discomfort and does not provide a simple or effective assessment of airflow through the nostrils. B. Refer patient to a nasal specialist to ensure there is not any blockage in the nasal cavity: Referral to a specialist is unnecessary for a basic assessment of nostril patency. The nurse can perform a simple, non-invasive test before considering a referral for further evaluation. C. Press each nostril shut and have the patient sniff to ensure air passage through each nostril: This method effectively assesses nostril patency. By occluding one nostril at a time, the nurse can evaluate airflow and determine if there is any blockage or obstruction in the nasal passages. It is a quick and straightforward assessment technique. D. Have the patient blow their nose into a tissue forcefully: Asking the patient to blow their nose can provide information about mucus presence or drainage but does not specifically assess nostril patency. This action may also cause discomfort and is not the best initial assessment for airflow through the nostrils.
