25
2 natural methods of contraception
Basal body temperature Cervical mucus charting
26
Barrier methods of contraception
Condoms, Diaphragm/Cap, IUD
27
Mod of action of an IUD
Small plastic device that is placed in the uterus to prevent fertilisation of the egg. The copper or hormone stops sperm moving through the uterus towards the egg.
28
Copper IUD
99 percent effective in preventing pregnancy. No hormonal side effects
29
Mirena IUD
99.5 percent effective in preventing pregnancy. Uses progestogen. Women will have lighter periods
30
Best time to insert an IUD
During or just after a menstrual period, 6 weeks after your baby is born, immediately after an abortion
31
Risks of IUD
1% chance of infection after first being inserted. Small risk of damage or perforation of the womb (roughly 1 in 1000). Rare chance of pregnancy with an IUD in place. Ectopic pregnancy. Copper IUD may cause more bleeding and cramping during periods. Can also cause an allergic reaction in some people. Mirena may initially cause irregular, light bleeding for more days than usual. Roughly 5% chance of IUD coming out itself.
32
Hormonal methods of contraception
Combined oral contraceptive pill Progesterone only pill Depo provera ECP
33
Combined oral contraceptive pill action
Preventing an egg being produced (ovulation) thickening the cervical mucus (which stops sperm getting through) altering the lining of the uterus so that if an egg does get fertilised it is less likely to implant and grow.
34
2 types of combined oral contraceptive pill
Monophasic - contains equal doses of oestrogen and progestogen Triphasic - contains differing levels of oestrogen and progestogen, which mimics a normal menstrual cycle.
35
Progesterone only pill action
Thickens mucus layer in cervix to stop sperm from entering uterus and fallopian tubes. Is effective 48 hours after taking. Some can also prevent ovulation.
36
Reason why women would take progesterone only pill
Can't tolerate oestrogen, have a history of blood clots, suffer from migraines, other medical conditions, breastfeeding
37
Important client education if taking progesterone only pill
Must be taken within 3 hours instead of 12 hours (combined pill is 12)
38
ECP action
Delays release of an egg from your ovary until sperm are no longer active, changes the lining of your uterus so a fertilised egg cannot implant and develop.
39
Success rate of ECP
95% of expected pregnancies when taken within 24 hours of sex, 85% if taken within 25-48 hours 58% if taken within 49-72 hours
40
Depo provera action
Contains progesterone - prevents pregnancy by stopping the ovaries releasing an egg each month. There are also changes to the lining of the womb (endometrium). Administered every 12 weeks
41
Why is a folic acid pill more beneficial than gaining it from leafy greens?
It is more readily absorbed and used in the body (bio-available) and stable than naturally occurring food folate
42
3 positive signs of pregnancy
foetal heartbeat, foetal movements, visualisation via ultrasound
43
Signs and symptoms of pregnancy
Amenorrhea, nausea/vomiting, breast changes, fatigue, urinary frequency
44

45

46
Lack of Vitamin D in pregnancy can cause
Rickets and bone development issues in baby
47
Role of Iodine in pregnancy
Helps the body grow and develop, especially the brain
48
Recommended Iodine dose while pregnant
Take 150mcg iodine-only tablet every day while pregnant and breastfeeding
49

Alcohol, Tobacco, NSAIDs, Rubella
50
What is a teratogen?
An agent that causes an abnormality following fetal exposure during pregnancy
51
Common discomforts in 1st trimester of pregnancy
Morning sickness, bleeding gums, urinary frequency, nasal stuffiness and epistaxis
52
Common discomforts in 2nd trimester of pregnancy

53
Common discomforts in 3rd trimester of pregnancy
Oedema, shortness of breath, varicose veins/phlebitis, backache
54
Multigravida
Woman who is pregnant for at least the second time
55
Signs of labour
Contractions, tablespoon of blood or brown sticky mucus, water breaks
56
First stage of labour
Contractions, mucus, water breaks, cervix dilates to 10cm
57
Second stage of labour
The neck of the womb is fully open and the baby is born. Can take 1-2 hours to push out first baby
58
Third stage of labour
More contractions as the whenua/placenta comes away from the wall of your uterus and out your vagina
59
Points to consider when assisting with emergency delivery
APGAR score, warm baby after birth, clamp umbilical cord, check placenta has been expelled, assess for excessive bleeding and perineal tear, massage uterus if no tear visible, encourage breast feeding
60
APGAR
Appearance, pulse, grimace, activity, respirations. Performed 1 min and 5 min after birth. Should score 10
61
Newborn screening tests
Weight, congenital dislocation of hips, guthrie's test (48hr), hearing test (1 month)
62
Neonatal jaundice
Liver is not mature enough to remove bilirubin from the blood
63
How is neonatal jaundice treated
Phototherapy
64
