Final Third of Class Flashcards
what is the single most dangerous event in a lifetime for a female
pregnancy
medical uses of contraception (beyond preventing pregnancy)
helps w/ irregular periods reduces dysmenorrhea decrease acne treats PCOS protection from PID, ovarian and endometrial cancer, fibrocystic breast disease, ovarian cysts, fibroadenomas of breast, anemia and STIs
least effective method of contraception
fertility awareness based d/t user error and complications
symptothermal
calendar/mucus/body temp/standard
what causes increase temp during ovulation
usually spike during ovulation d/t increased progesterone
use contraception that day and 3 days after
billings (mucus)
before ovulation - clear, water, stretchy (estrogen dominant)
thick, white and sticky when not fertile (spinnbarkeit)
Standard method: if you have a regular cycle (26-32).. when to avoid sex
days 8-19
calendar rhythm method
record cycles for 6 months
take shortest cycle and subtract 18 days
take longest cycle and subtract 11 days
don’t have sex b/w those days
barrier methods
second least effective
prevent sperm from entering uterine cavity
d/t user error and inconvenience
types of barrier methods
condoms (male and female)
contracetpive sponge
cervical cap
diaphragm
contraceptive sponge
moisten sponge with water
leave in place for 6-8 hours post coital (less than 24 hours)
What to avoid with condoms (3)?
avoid oil based lubricants, monistat, estrogen creams
Also female condom can be inserted 8 hours prior to coitus
diaphragm
requires fitting and referring requires spermicide leave in place for 6-8 hours post coital no more than 24 hours clean with soap and water
cervical cap
requires fitting
requires spermicide
leave in place for 6-8 hours post coital (no more than 48 hours)
spermicide risk
vaginal walls become more susceptible to HIV
hormonal methods
COC
vaginal ring
progestin minipill
patch
what pill do you use while breasfeeding
minipill = progestin only
COC pills
estrogen and progestin
extended use - 4 years
contraindicated with smokers
patch
weekly application for 3 weeks
slight risk of thromboembolism
vaginal ring
nuva ring
inserted for 3 weeks and removed for 7 days
depo-provera
progestin only
injected every 3 months
long-acting reversible (LARC)
intraueterine
nexplanon
IUD
Copper - 10 years - non hormonal
Progesterone - Mirena (5 yrs), Skyla (3 yrs), Liletta (3 yrs), Kyleena (3 years)
nexplanon
sits under skin progestin good for only 3 years prevents ovulation, thickens mucus AE: weight gain, headaches, irregular menses, acne
most effective method of contraception
operative sterilization = vasectomy and tubal ligation
after getting vasectomy, how long does it take to clear remaining sperm?
3 months
15-20 ejaculations
*no effect on sexual function
post coital contraception
sooner taken, the more likely it’ll work (within 12 hours)
unlikely to prevent implantation
AE of post coital contraception
nausea, HA, irregular bleeding
what post coital contraception works by inhibiting or delaying contraception
plan B (w/i 72 hours) - progestin only - interferes with ovulation
ella (w/i 5 days) - progesterone modulator
yutze method - combined progestin-estrogen pill
what post coital contraception prevents fertilization
paraguard (within 5 days) - copper IUD
may affect oocyte and endometrium
pregnancy
implantation in the uterine wall of a fertizlied ovum, most fertilized eggs naturally fail to implant
What are the three things contraception can block to prevent pregnancy
interference with ovulation, fertilization or implantation
abortion
ends an established pregnancy after implantation
miscarriage and therapeutic
hormonal contraception
use estrogen/progestone to prevent ovulation and thicken cerivcal mucus
do LARCs, plan B and Ella disrupt existing pregnancies
no
plan b and ella work by preventing ovulation
t/f: hormonal and copper IUDs work by preventing sperm from reaching and fertilizing an egg
true - copper IUD can prevent implantation of a fertilized egg

unilateral or bilateral occlusion of posterior nares
bone is blocking 1 or 2 nasal passages

fistula b/w trachea and esophagus below normal openings to esophagus and trachea
and upper part of esophagus dead ends

CPAP
type of mechanical ventilation
helps newborns breathe - but newborns are breathing on their own
steady flow of air keeps alveoli from collapsing after each breath
less hazards than ventilators b/c they don’t have enough surfactant
