Answer to Question 1

Ans:
C

Feedback:

ENG is an examination that records eye movements in response to vestibular, visual, cervical (vertigo triggered by somatosensory input from head and neck movements), rotational, and positional stimulation. With ENG, the velocity, frequency, and amplitude of spontaneous or induced nystagmus and the changes in these measurements brought by a loss of fixation, with the eyes open or closed, can be quantified. The Romberg test, rotational tests, and caloric stimulation do not allow for these data.

Answer to Question 2

Ans:
C

Feedback:

There are multiple potential causes of amblyopia, including cataracts. A deficit of rods or cones, a neural pathway disorder, and chronic conjunctivitis are not noted to be common precursors.
