Mnemonic for cranial nerves:Oh (Olfactory)Oh (Optic)Oh (Oculomotor)To (Trochlear)Touch (Trigeminal)And (Abducens)Feel (Facial)Virgin (Vestibulocochlear)Girls' (Glossopharyngeal)Vaginas (Vagus)And (Accessory)Hymens (Hypoglossal)To remember motor, sensory or both:SomeSayMarilynMonroe,ButMyBrotherSaysBridgetteBardotMovesMen Nerve [Classification] [Major functions] AssessmentI Olfactory Sensory Smell Have patient identify a familiar scent with eyes closed (usually deferred).II Optic Sensory Vision (acuity and field of vision); pupil reactivity to light and accommodation (afferent impulse)Have patient read from a card or newspaper, one eye at a time. Test visual fields by having patient cover one eye, focus on your nose, and identify the number of fingers you’re holding up in each of four visual quadrants.III Oculomotor Motor Eyelid elevation; most EOMs; pupil size and reactivity (efferent impulse)Check pupillary responses by shining a bright light on one pupil; both pupils should constrict. Do the same for the other eye. To check accommodation, move your finger toward the patient’s nose; the pupils should constrict and converge. Check EOMs by having patient look up, down, laterally, and diagonally.IV Trochlear Motor EOM (turns eye downward and laterally)Have patient look down and in.V Trigeminal Both Chewing; facial and mouth sensation; corneal reflex (sensory)Ask patient to hold the mouth open while you try to close it and to move the jaw laterally against your hand. With patient’s eyes closed, touch her face with cotton and have her identify the area touched. In comatose patients, brush the cornea with a wisp of cotton; the patient should blink.VI Abducens Motor EOM (turns eye laterally)Have patient move the eyes from side to side.VII Facial Both Facial expression; taste; corneal reflex (motor); eyelid and lip closureAsk patient to smile, raise eyebrows, and keep eyes and lips closed while you try to open them. Have patient identify salt or sugar placed on the tongue (usually deferred).VIII Acoustic Sensory Hearing; equilibriumTo test hearing, use tuning fork or rub your fingers, place a ticking watch, or whisper near each ear. Equilibrium testing is usually deferred.IX Glossopharyngeal Both Gagging and swallowing (sensory); tasteTouch back of throat with sterile tongue depressor or cotton-tipped applicator. Have patient swallow.X Vagus Both Gagging and swallowing (motor); speech (phonation)Assess gag and swallowing with CN IX. Assess vocal quality.XI Spinal accessory Motor Shoulder movement; head rotationHave patient shrug shoulders and turn head from side to side (not routinely tested).XII HypoglossalMotorTongue movement; speech (articulation)Have patient stick out tongue and move it internally from cheek to cheek. Assess articulation.Reference: http://rn.modernmedicine.com/rnweb/a....jsp?id=120796 AIRBORNE: Single room, use negative airflow pressure, use MASK or Resp Protection device, Put mask on client if he leave room.

Transdermal: patch should not be cut, place on hairless area and rotate sites,. wash skin with soap and water and dry thoroughly before placing patch, remove patch at night so that you don't develop tolerance if pain is unrelieved in 5 mins then call 911, client can take up to two more doses at 5 minute intervals. DIGOXIN (cardiac glcosides)used to increase force of myocardial contraction but decrease heart rate so ventricles have more time to fill. Treats heart failure and atrial fibrillation. Side effects dysrhythmias, monitor potassium b/c hyperkalemia and lead to dig toxicity, monitor dig level to ensure that it is between .05-.08 SIDE EFFECTS_ GI: n/v, anorexia, abdominal pain, fatigue, weakness, diplopia, blurred vision, yellow-green or white halos around objects Ace inhibitors increase risk of hyperkalemia which decreases effects of digoxin, quindine increase risk of dig toxicity if used concurrently.

Monitor carefully: major side effects"What is the role of the thymus gland in MG? The thymus gland, found in the upper chest area beneath the breastbone, is a part of the body's normal immune system. In most adults with MG, the thymus gland is abnormal. Some people with MG develop thymomas or tumors on the thymus gland. Generally thymomas are benign, but they can become malignant (cancerous). The relationship between the thymus gland and MG is not yet fully understood."S/S myasthenia gravis:Drooping of one or both eyelids (ptosis) Blurred or double vision (diplopia) due to weakness of the muscles that control eye movements Unstable or waddling gait Weakness in arms, hands, fingers, legs, and neck Change in facial expression Difficulty in swallowing and shortness of breath Impaired speech (dysarthria) Shortness of breath Source: http://www.4woman.gov/faq/mgravis.htm Meds. for Infections: Everything noted down is from Genny's note on meds for infections.
