Hint : 💡Think about the usual exam distance used when holding a penlight or finger in front of a client’s eyes.

Correct Answers:

  • 31 cm


Rationale :

🧠During assessment of extraocular movements, the nurse typically holds an object or finger about 30 to 35 cm (12 in) from the patient’s eyes to observe tracking.

👁️This distance allows the patient to follow the object through the six cardinal fields of gaze without eye strain or loss of focus.

📏Holding the object at approximately 31 cm is close to the standard 30 cm, making it the most accurate option for correct assessment technique.

🩺Using the correct distance ensures more reliable evaluation of cranial nerves III, IV, and VI, which control eye movement.

📌Core Message

Proper assessment of extraocular movements is done with an object held about 30–35 cm from the eyes to accurately assess ocular motility and cranial nerve function.
