When caring for a client with impairment to cranial nerve II, the nurse should verbally explain nursing interventions in detail.
What are the cranial nerves?
- The cranial nerves are formed of 12 paired nerves which are present at the back of human brain.
- Cranial nerves function is to send electrical signals between the brain, face, neck and torso.
- These help a person to see, taste, detect smell, hear and feel sensations around them.
- They also help in movements like facial expressions, eye blinking and movement of tongue.
- These 12 cranial nerves are named as follows based on their function: CN I (olfactory), CN II (optic), CN III (oculomotor), CN IV (trochlear), CN V (trigeminal), CN VI (abducent), CN VII (facial), CN VIII (vestibulocochlear), CN IX (glossopharyngeal), CN X (vagus), CN XI (accessory) and CN XII (hypoglossal).
- Damage to 2nd cranial nerves results in optic disorders i.e. there is complete or partial vision loss in the affected eye.
- Therefore, the patient must be verbally explained the nursing interventions as he cannot see.
