triggers for migraines and cluster headaches
alcohol, allergies, intense odors, bright lights, fatigue, anxiety, hormone fluctuations
migraine expected findings
photophobia and phonophobia, n,v, stress, anxiety, unilateral pain, alteration in ADLs for 4-72 hr
migraine prodromal phase
awareness of findings for hours before onset
aura phase - migraine
numbness, tingling of mouth, lips, hands, face; acute confusion; visual disturbances
second migraine stage
severe, incapacitating, throbbing headache that intensifies over several hours and comes with n, v, drowsiness, vertigo
third migraine stage
4-72 hrs. headache is dull
the older client can experience an aura without
pain. this is called a visual migraine
status migrainous
longer than 72 hours.
migrainous infarction
neurological manifestations persist for 7 days, neuroimaging can indicate ischemic infarct
abortive therapy
to alleviate pain during aura or soon after start of headache. NSAIDS, tylenol, OTC anti-inflammatory agents for migraine, antiemetics. for severe you can give triptan preparations, ergotamine, isometheptene
triptan preparations
produce a vasoconstrictive effect

foods that can trigger migraines
tyramine foods - pickles, caffiene, beer, wine, aged cheese, artificial sweeteners, MSG
medicines that can induce migraines
estrogen, nitroglycerin, nifedipine
which food should a nurse suggest a migraine patient should avoid
salted cashews bc nuts contain tyramine
a patient with a history of migraines and a new prescription for zolmitriptan indicates understanding with which statement
“i should expect facial flushing when i take this medication”
what are expected findings in someone with cluster headaches?
altered sleep-wake cycle, headache 1-8 times daily, nasal congestion and drainage
which instruction is pertinent for someone who was just diagnosed with migraines
apply a cool cloth to the face during a headache
which question should be asked to identify the aura type of migraine headaches
do you have the same manifestations each time the headache occurs
age related macular degeneration
central loss of vision that affects the macula of the eye. there is no cure and this is a common cause of vision loss in older adults
dry macular degeneration
most common and is caused by a gradual blockage in retinal capillary arteries which results in the macula becoming ischemic and necrotic due to lack of retinal cells
wet macular degeneration
less common than dry. caused by new growth of blood vessels that have thin walls that leaks blood and fluid. can occur at any age
risk factors of dry macular degeneration
smoking, hypertension, female, short body stature, family history, diet lacking carotene and vitamin e

when should you start getting annual eye exams
after 40
cataracts
an opacity in the lens of an eye that impairs vision. decreased visual acuity, blurred vision, diplopia
eye meds
anticholinergic agents - atropine 1%. prevents pupil constriction for prolonged periods of time and relaxes muscles in the eyes. used to dilate the eyes preop for visualization of internal structures. fast onset, long duration. effects can last 7-12 days
activities that can increase IOP
bending over, sneezing, blowing nose, coughing, straining, head hyperflexion, restrictive clothing, sex.
glaucoma
disturbance of the functional or structural integrity of the optic nerve. decreased fluid drainage or increased secretion that can increase IOP and cause atrophic changes of the optic nerve and visual defects
frequent cause of blindness.
serotonin agonist that can be given for migraines
sumatriptan (imitrex)
expected range for IOP
10-21 mmhg
primary open angle glaucoma
more common form. open angle between iris and sclera. aqueous humor outflow is decreased due to blockages in the eye’s drainage system causing a gradual rise in IOP
primary close angle glaucoma
IOP rises suddenly. the angle between the iris and sclera suddenly close causing a corresponding increase in IOP. sudden onset and requires immediate treatment
secondary glaucoma
can result from trauma, eye surgery, tumors of the eye, uveitis, irisitis, neurovascular disorders, degenerative disease or central retinal vein occlusion
findings for primary open angle glaucoma
headache, mild eye pain, loss of peripheral, decreased accommodation, halos around lights, elevated IOP (22-32 mmhg)
findings in primary angle closure glaucoma
rapid onset elevated IOP (30 mmhg or higher) decreased or blurred visions, colored halos around light, pupils nonreactive to light, severe pain and nausea, photophopbia
tonometry
measures IOP
gonioscopy
used to determine the drainage angle of the anterior chamber of the eyes
if multiple eye drops are prescribed
wait 5-10 min between drops to keep them from diluting each other

carbachol, echothiophate, pilocarpine - miotic meds that constrict the pupil and allows for improved circulations and outflow of the aqueous humor. can cause blurred vision
pilocarpine good second-line drug for POAG
adrenergic agonists
apraclonidine, brimonidine, tartrate, dipivefrin hcl. reduces IOP by limiting production of aqueous humor and dilates the pupils to improve the flow to the sight of absorption
beta blockers (opthalmic)
timolol. first line drug therapy for glaucoma, and decrease IOP by reducing aqueous humor production.
can be absorbed systematically and cause bronchoconstriction and hypoglycemia. caution in those with asthma, COPD, and DM
carbonic anhydrase inhibitors
acetazolamide, dorzolamide, brinzolamide - decrease IOP by reducing aqueous humor production. THIS IS A SULFA BASED DRUG
prostaglandin analogs
bimatoprost, latanoprost. increase outflow fot eh uveosclera by dilating blood vessels in the trabecular mesh where aqueous humor is collected and then drains the humor at a more rapid rate
check for corneal abrasions and dont instill if cornea not intact. can cause iris to darken with long term use
systemic osmotics
mannitol and oral glycerin. mannitol used in emergency for POAG to quickly decrease IOP
glaucoma surgery
laser trabeculetomy, iridotomy, or placement of a shunt are procedures used to improve the flow of the aqueous humor by opening the channel out of the anterior chamber of the eye
patient has DM and reports a gradual loss of peripheral vision
POAG
