Unit 13 - Repro Flashcards
two main sexual/repro hormones in females
estrogen & progesterone
T/F: female hormones affect every system of the body
T
Estrogen is mostly secreted by ____
ovaries
progesterone is secreted by ______
corpus luteum (sack that contains egg expelled from ovary)
at the end of the menstruation cycle, the negative feedback loop shuts off ______
secretion
What hormone:female: ova maturation, estrogen productionmale: sperm production
FSH
What hormone:female: triggers ovulation & dev corpus luteum = progesteronemale: testosterone
LH
What hormone:dev. sec. characteristics, regulates ovarian & menstrual cycles
Estrogen/Progesterone
estrogen ____ LDL
decreases
estrogen ____ HDL
increases
estrogen _____ strength & length of bones
increases
T/F: estrogen prevents cardiac disease & osteoporosis
T
What is estrogen combined with to counteract adverse effects
progestins
Therapeutic effect of estrogen
Treatment of hot flashes & night sweats, relieve painful intercourse, prevent osteoporosis, treat prostate and some breast cancers
contraindications/interactions of estrogen
- hx of breast/cervical/endometrial/prostate cancer- hx of blood clots (estrogen increases clotting)- lipid disorders (estrogen raises HDLs & triglycerides)***pregnancy category X
adverse effects of estrogen
- HA- N, V*- libido (sex drive) changes- weight gain- dose dependent (higher dose = more significant effects)
nursing considerations/pt. teaching for estrogen
BLACK BOX WARNING: when used alone, risk for endometrial cancer in postmenopausal women- CV disorders- thromboembolism disorder- repo cancers- monitor for allergies to soy- discourage use of plant estrogens with conjugated astrogens- no pregnancy/breast feeding- report s/s resp. distress- mo. breast exams- report sudden onset of HA, chest pain- can not use tampons while on vaginal cream: will make med less ineffective- monitor for relief of menopausal symptoms
what hormone promotes breast development
progesterone
decreased levels of progesterone causes ____
menses
what hormone maintains endometrium in early pregnancy
progesterone
2 problems progesterone treats
- dysfunctional uterine bleeding2. endometrial cancer
progesterone ____ midcycle LH surge = ____
inhibits = prevents ovulation
progesterone ____ thick cervical mucus
encourages
difference between progesterone & estrogen
estrogen encourages endometrial growthprogesterone limits/stabilizes endometrial growth
why is medroxyprogesterone usually only given 5-10 days
because that is the time a women is usually menstruating
therapeutic effects of medroxyprogesterone
Prevents endometrial proliferation and decreases dysfunctional bleeding, prevents ovulation, treatment for endometrial cancers
contraindications/interactions of medroxyprogesterone
- clotting disorders- pregnancy- hepatic impairment- breast, uterine, vaginal cancer- depression
adverse effects of medroxyprogesterone
BLACK BOX: if combined with estrogen = increase risk for stroke, DVTs, MI, PE, or breast cancer*- injectable form decreases bone mineral density (osteoporosis)- breast tenderness- breakthrough bleeding
nursing considerations/pt. teaching for medroxyprogesterone
- decreased effects c rifampin barbiturates- used for decreasing vaginal bleeding, method of BC- discourage smoking- possible breakthrough bleeding- monitor bone density, may increase bone loss- no pregnancy- s/s of fab 4- encourage self-breast exams- mid-cycle spotting can occur- s/s DVT- infertility can last up to 18 mo.- black box: check for lumps, breast cancer- monitor wt for fluid retention, BP, pulse, labs- report sudden severe HA, V, dizziness, fainting, numbness in arms, chest pain
Therapeutic effects of Estradiol/Norethindrone
Prevent conception, treat acne, treat endometriosis, regulate bleeding, decrease pain with menstruation
contraindications/interactions of Estradiol/Norethindrone
- absolute contraindication: current breast cancer, cirrhosis of liver, major surgery with immobility, migraines, decreased cardiac function, valvular HD, hypertension, smokers, hx of stroke, lupus, hx or risk of DVTs
adverse effects of Estradiol/Norethindrone
- vision changes- N- weight gaine- breast tenderness- breakthrough bleedings- increased BP
nursing considerations/pt. teaching for Estradiol/Norethindrone
BLACK BOX: smoking significantly increases risk of cardiovascular side effects, especially in pt’s over 35- adverse effects of mimics of pregnancy: N, V, breast tenderness- no pregnancy! no breast feeding!*- take as prescribed- report fab 4: PE, stroke, MI, DVT- report abnormal vaginal bleeding- monitor VS (BP)- s/s CV issues, abdominal pain- anovulation or amenorrhea may occur up 6 mo. after stopping med- use barrier method of birth control within 1st wk of taking- report if 2 periods are missed- patch? only use 1 at a time- monitor wt. gain for fluid retention- breast feeding? use alternate birth control
how emergency contraception works
prevents ovulation, does not affect already released egg (abortion), huge dose of estrogen
what hormone matures male reproduction system
testosterone
what hormone causes sec. sex characteristics for males
testosterone
