A 20-year-old male patient is admitted with a head injury after a collision while playing football. After noting that the patient has developed clear nasal drainage, which action should the nurse take?
a. Have the patient gently blow the nose.
b. Check the drainage for glucose content.
c. Teach the patient that rhinorrhea is ex-pected after a head injury.
d. Obtain a specimen of the fluid to send for culture and sensitivity.
ANS: B
Clear nasal drainage in a patient with a head injury suggests a dural tear and cerebrospinal fluid (CSF) leakage. If the drainage is CSF, it will test positive for glucose. Fluid leaking from the nose will have normal nasal flora, so culture and sensitivity will not be useful. Blowing the nose is avoided to prevent CSF leakage.
