When testing cranial nerve I in an elderly client who has had a head trauma, in which sequence would the nurse perform the procedure?
1) hold vial with aromatic odor under the open nostril and instruct client to inspire
2) assess nose for patency by occluding one nasal wing at a time and asking client to sniff inward with the unoccluded nostril
3) have client close eyes and occlude one nostril
4) inspect the mucous membranes of the nares with an otoscope and speculum
5) 5. have client identify aromatic odors as presented
