Rasmussen College, Mankato - NUR 2571 PN2 EXAM 3

Rasmussen College, Mankato - NUR 2571 PN2 EXAM 3 EXAM 3 MODULES 7, 8 and 9. A & P of face and ear bones – look at sheet she gave us with cranial nerves Cranial Nerve 1: Olfactory (smell) Cranial Nerve II: Optic (Vision) – Vision test. Cranial Nerve III: Oculomotor (pupil size, eyelid elevation)- having both pupils constrict with light, move finger to see if both eyes can follow. Cranial Nerve IV: Trochlear (EOM-turn eyes downward and laterally) have patient look down and in Cranial Nerve V: Trigeminal (chewing, facial and mouth sensation) Having patient identify where you touch with a cotton ball, open mouth and shut. Cranial Nerve VI: Abducens (EOM- eyes turn laterally) side to side Cranial Nerve VII: Facial (expression, taste, lip closure) Smile, raise eyebrow, identify salt or sugar Cranial Nerve VIII: Acoustic (hearing): turn fork, whisper test, equilibrium Cranial Never IX: Gloddopharyngeal (gagging, swallowing, taste) gagging quality and vocal quality Cranial Nerve X: Vagus (gagging, swallowing, speech) Check vocal and gagging. Cranial Nerve XI: Spinal accessory (shoulder movement and head rotation) shrug shoulder, and move head side to side. Cranial Nerve XII: Hypoglossal (tongue movement and speech) stick out tongue! Cranial Nerves IX and V control dysphagia Cranial Nerve that is responsible for vision: Cranial Nerve II Eye Vocab:  Hyperopia: farsightedness, can see far but not close up  Myopia: Nearsightedness, close object can be seen but object far are blurry  Astigmatism: irregular shape of the cornea, makes vision blurry.  Presbyopia: condition with age, diminished ability to focus on near objects.  Amblyopia: lazy eye- can result in permanent loss of vision  Ptosis: drooping of the eye Cranial Nerve that is responsible for vision: Cranial Nerve II Glaucoma: is high pressure from obstruction in the eyes- 2nd leading blindness  Group of diseases related to the amount of intraocular pressure in the eye occurring as a result of neurodegenerative processes.  NO CURE. Damage is irreversible but progression can be controlled with eye drops, oral meds, laser procedures or surgery.  Hypertension of the eye. The channels that drain the fluid within the eye become blocked, increasing the pressure. This eventually causes damage to the retina. o There are 2 main types: open angle (occurs over time) and closed angle (sudden onset).  Open-angle glaucoma -due to an increase in IOP and the channels that drain fluid become blocked. Pressure backs into the vitreous humor, which causes retinal damage.  Closed-angle glaucoma - due to a similar increase in IOP, but it's sudden. o Signs/Symptoms of Glaucoma Open angle - gradual loss of vision with few symptoms, wide angle between cornea and iris. Closed angle - sudden onset, HA, blurry vision, pain in the eye and is the narrow angle between iris and cornea! Report pain in the eye! o Meds (Rx) for Glaucoma:  Beta blockers - [reduce aqueous inflow], and prostaglandins- [increases aqueous humor outflow]  Timolol (timoptic) – for open angle o Meds (Rx) for open & closed glaucoma  The same meds are used for both (prostaglandins and beta blockers) but meds are temporary in closed-angle glaucoma until surgery can be done.  Latanoprost (xalatan) – gold standard rx. o Surgery
