Which behavior causes the nurse to report a positive Romberg test?
The patient cannot touch his nose with eyes closed.
The patient sways from side to side.
The patient complains of dizziness.
The patient cannot keep his eyes closed.
The Correct Answer is B
A. Inability to touch the nose with eyes closed is part of the finger-to-nose test, not the Romberg test.
B. A positive Romberg test is indicated when the patient sways or loses balance while standing with feet together and eyes closed. This suggests a problem with proprioception or the vestibular system.
C. Dizziness may occur during the test but does not constitute a positive result unless accompanied by swaying or imbalance.
D. The patient being unable to keep eyes closed is not a criterion for a positive Romberg test. The test evaluates balance, not voluntary eye closure.
