The emergency department nurse is assessing a client following a motor vehicle accident. The nurse notes facial deformities with swelling and bleeding and a clear drainage coming from the nares
Which diagnostic test is completed to determine if the clear drainage is cerebrospinal fluid? A) A serum CBC
B) A Nitrazine paper
C) A Dextrostix
D) A glucometer check
C
Feedback:
When clear drainage is observed from the nares of a client, a Dextrostix is used to determine the presence of glucose which is present in cerebrospinal fluid. A serum CBC would provide information on red and white blood cell count. A low red blood cell count is may be found due to hemorrhage that has occurred. Nitrazine paper is under to assess vaginal secretions for the presence of amniotic fluid. A glucometer check will provide information on serum glucose, not the glucose level in the cerebrospinal fluid.
