Menorrhagia - excessive bleeding during menstruation, lasts more than 7 days, can be caused by
endocrine, coagulation, or systemic disorders. Symptomatic relief is accomplished w/ NSAIDs,
progestins, & hormonal contraceptives w/ combinations of progesterone & estrogen. D&C is done for
symptomatic relief. Endometrial ablation (detachment of lining of uterus) by photodynamic therapy or
uterine balloon therapy is a potential nonsurgical alternative. Photodynamic therapy used: light
sensitive substance applied to endometrial tissue, laser probe inserted through cervix, the laser light
causes sloughing of endometrium. Uterine balloon therapy used: balloon into uterus, balloon filled w/
isotonic saline solution, & heating solution to 87° for 8 minutes.
Endometriosis - tissue similar to lining of endometrium is found outside of the uterus. Cause: retrograde

use contraceptives.
Childhood vaccination schedule
Types of immunity

Urinary
Renal failure - Acute: sudden, rapid ↓ in renal fc, reversible w/ early tx, 4 phases (onset-reduced blood
flow), oliguric (<urinary volume occurs w/ in 48 hrs), diuretic (↑ water excretion, waste & electrolyte
secretions impaired: BUN, Cr, P, K-↑ in blood). Risk: hypovolemia/dehydration. Output <500 mL/day,
retention (K, Cr). N recovery 3-12 months or longer. ↑ GFR, decline BUN. (S/S - urinary change
(1.010-1.025) & osmolality, fluid volume excess (edema, HTN, CHF), metabolic acidosis-hydrogen ions
build up, bicarb used up-cause lethargy & stupor. Na+ may not be conserved by the kidneys. K+ excess ↑
putting heart at risk. Anemia (hematopoietic fc ↓, altered WBC levels-infection, Ca & deficit. Neurologic

fistula to prevent infection, palpate for thrill, listen for bruit, ✓ color of skin, clean skin w/ soap & water,
avoid puncturing same site, & after dialysis don’t administer injection for 2-4 hrs. AV graft: plastic graft,
lasts less, 14 days can use, clogged easily, 3-5 years, bleeding issue. Client teaching: avoid lifting heavy

Macular degeneration, glaucoma, cataract - Macular degeneration: is damage to the macula and usually

d/t leaky BV around macula. 1st symptom - blurred vision/distorted vision. S/S: color vision disturbance,
difficulty reading, if the macula is irreparably damaged bulls eye area is absent (loss of central image),
peripheral vision is usually okay, clients can’t see by looking at images directly, turn head to side. Dx:
angio of eye. Med Mgt: laser (in early stages), magnifying glasses, & high intensity reading lamps. Nsg
Mgt: assist w/ ADL’s, assist w/ coping, & when walking turn head side to side. Glaucoma: 2nd MC
cause of blindness, d/t imbalance b/n production and drainage of aqueous fluid, when drainage is
obstructed = rising IOP (N: 10-21 mmHG), OAG: MC, CAG: LC, normal tension – IOP N but optic
nerve damage and loss of vision still occur, congenital, >40 y.o, family hx., DM, & high in AA, & 2ndary
(steroids, eye infections trauma). OAG: slow onset, degeneration & obstruction at trabecular network, &
increase IOP. CAG: sudden/acute onset, at narrowed junction where iris meets cornea, & attacks where
iris thicken w/ mydriatic drugs or pupil dilation in dark room. S/S: eye discomfort, blurry vision, halos,
decreased peripheral vision, feeling prescription glasses need to be changed. If closed angle: rock hard
eyes, pain, loss of vision,emergency, red conjunctiva, & corneal becomes cloudy. Med Mgt: mitotics

can be controlled. are cloudy opacity of lenses. Causes: congenital/familial tendency, trauma, aging
process, increase incidence in DM, UV rays/Rx, & steroids. S/S (earliest): halo sign around lights,
difficulty in reading, change in color vision, increase glaring, & distortion of objects. S/S (late): client can
only read the largest letter on the Snellen chart. White/gray spot visible behind pupil. Dx: slit lamp and
tonometry (pressure in eye). Sx: removal of cataract and done in an outpatient under LA. After sx: A eye glasses (eyes w/o lens cause client to see objects ⅓ larger than N, must use 1 eye to avoid seeing
distorted image, common to see coating applied to 1 side of eye glasses so only operated eye w/ corrective
lens is used), B - intraocular lens (MC & best). C - contact lenses (removed at night, cleaned, reinserted
daily, peripheral vision is not lost & objects appear abt actual size. Cx after cataract sx - infection,
hemorrhage, retinal detachment, & clouding of lens. Nsg. Mgt (teach) - avoid coughing, sneezing, heavy

Otitis media - acute inflammation of the middle ear, usually unilaterally, serous-collection of pathogen
free fluid being tympanic membrane, purulent from spread of microorganisms from eustachian tube to
middle ear, fluid or pus increases pain, diminished hearing, pressure in middle ear, tympanic membrane
look red. Med mgt: tympanectomy, myringotomy (incisional opening of tympanic membrane),
