Question

the nurse is assessing cranial nerves 3, 4, and 6 (oculomotor, trochlear, and abducens). which technique might the nurse use to assess all three in one technique?

Answer 1

To assess the cranial nerves 3,4, and 6 all at once, the nurse should use the test eye movement technique using the penlight.

To test cranial nerves III, IV, and VI (oculomotor, trochlear, and abducens) together.

Test the eye movement with a penlight. Stand 30 cm in front of the patient and ask them to follow the direction of the penlight with their eyes only. At eye level, move the penlight left to right, right to left, top to bottom, top right to bottom left, and top left to bottom right. Also, pay attention to eye movements in all fields. An unexpected finding is an involuntary eye tremor called nystagmus.

Test the pupils on both sides to make sure they are evenly rounded and respond to light and accommodation. Dim the lights in the room before running this test. The pupil should be round and the same size on both sides.
