A 42-year-old patient who is admitted to the emergency room following blunt trauma to the face has clear fluid draining from the right nostril. The nurse assesses this fluid for:
A) Sodium
B) Protein
C) Calcium
D) Glucose
Ans: D
Feedback: Clear fluid draining from either nostril suggests a fracture of the cribriform plate with leakage of cerebrospinal fluid. Because cerebrospinal fluid contains glucose, it can readily be differentiated from nasal mucous by means of a dipstick (Dextrostix). Sodium, protein, and calcium cannot be assessed by Dextrostix.
