Nervous System, Cranial Nerves
| Question | Answer |
|---|---|
| When does neural tube development occur | 3 – 4 weeks gestation |
| What eventually becomes the CNS | Neural tube |
| What can failure of the neural tube to close cause | Spina bifida |
| What may detect CNS dysfunction | Neurological check, skull x-ray, EEG, CT, MRI, electromyography, newborn reflexes, decreased LOC in an ill child |
| What is the finger nose test used to determine and how | Coordination – child is asked to extend the arm and then to touch the nose with the index finger with the eyes open and closed |
| If the school age child can’t do this, further follow up is required | Stand on one foot |
| What are the 12 cranial nerves | Olfactory, Optic, Occularmotor, Trochlear, Trigeminal, Abducens, Facial, Accoustic, Glossopharyngeal, Vagus, Spinal Accessory, Hypoglossal |
| What is facial nerve # 1 | Olfactory |
| What is facial nerve # 2 | Optic |
| What is facial nerve # 3 | Oculomotor |
| What is facial nerve # 4 | Trochlear |
| What is facial nerve # 5 | Trigeminal |
| What is facial nerve # 6 | Abducens |
| What is facial nerve # 7 | Facial |
| What is facial nerve # 8 | Acoustic |
| What is facial nerve # 9 | Glossopharyngeal |
| What is facial nerve # 10 | Vagus |
| What is facial nerve # 11 | Spinal Accessory |
| What is facial nerve # 12 | Hypoglossal |
| Which cranial nerve controls smell | #1 – Olfactory |
| Which cranial nerve controls sight | #2 – Optic |
| Which cranial nerve controls dilation of the pupil, single vision, and opens the eye | #3 – Ocularmotor |
| Which cranial nerve controls rotation of the pupil and single vision | #4 – Trochlear |
| Which cranial nerve controls sensations of the face and chewing | #5 – Trigeminal |
| Which cranial nerve controls eye movement and single vision | #6 – Abducens |
| Which cranial nerve controls forehead wrinkling, closing eyes, and facial muscles | #7 – Facial |
| Which cranial nerve controls hearing | #8 – Accoustic |
| Which cranial nerve controls swallowing and tasting | #9 – Glossopharyngeal |
| Which cranial nerve controls voice and visceral nerve function | #10 – Vagus |
| Which cranial nerve controls head rotation and shoulder movement | #11 – Spinal Accessory |
| Which cranial nerve controls the tongue | #12 – Hypoglossal |
| Which are the sensory cranial nerves | 1, 2, 8 |
| Which are the motor nerves | 3, 4, 6, 11, 12 |
| Which nerves are both sensory and motor | 5, 7, 9, 10 |
| A dysfunction in cranial nerve I will likely involve what problem and nursing intervention | Inability to smell, suppressed appetite – Present food attractively |
| A dysfunction in cranial nerve II will likely involve what problem and nursing intervention | Inability to control pupil reflexes – Protect eyes from glaring lights |
| A dysfunction in cranial nerve III will likely involve what problem and nursing intervention | Double vision – Cover eyes |
| A dysfunction in cranial nerve IV will likely involve what problem and nursing intervention | Inability to move eyes – Remain in child’s view when communicating |
| A dysfunction in cranial nerve V will likely involve what problem and nursing intervention | Difficulty chewing – Provide soft foods |
| A dysfunction in cranial nerve VI will likely involve what problem and nursing intervention | Inability to control corneal reflexes – Have ointment or eye patch on hand to protect cornea |
| A dysfunction in cranial nerve VIII will likely involve what problem and nursing intervention | Inability to hear – Maintain body language for communication |
| A dysfunction in cranial nerve VII will likely involve what problem and nursing intervention | Inability to close eye – Protect eyes with moist dressing |
| A dysfunction in cranial nerve IX will likely involve what problem and nursing intervention | Inability to taste or control gag and cough reflexes – Provide visually attractive food and Keep tracheotomy tray and suction at bedside |
| A dysfunction in cranial nerve X will likely involve what problem and nursing intervention | Difficulty in talking or swallowing; visceral malfunction – Provide means of communication, Assess for aspiration, Assess body system function and vital signs |
| A dysfunction in cranial nerve XI will likely involve what problem and nursing intervention | Problems controlling head, turning and shrugging shoulders – Provide position changes and support |
| A dysfunction in cranial nerve XII will likely involve what problem and nursing intervention | Thick speech, problems with tongue movement – Have suction ready, Observe ability to chew and swallow, Provide method of communication |
