- ) The test - simple, safe, precise, validated, accepted by population
- ) The intervention - effective intervention with evidence of better outcomes
- ) Screening programme - RCT evidence + clinically, socially, ethically acceptable

Between which vertebrae is epidural given?
L3/4
The APGAR score is used to assess health of newborns. What does APGAR stand for?
Appearance (skin colour) Pulse Grimace (reflex irritability) Activity (muscle tone) Respiration =>A score of 0-3 is very low score, between 4-6 is moderate low and between 7 - 10 means the baby is in a good state
A 28-year-old woman is admitted to the labour ward at 38+4 weeks gestation. This is her first pregnancy and she tells you that contractions started around 10 hours ago. On examination, her cervix is positioned anteriorly, is soft, and is effaced at around 60-70%. Cervical dilatation is estimated at around 3-4cm and the fetal head is located at the level of the ischial spines. She has had no interventions performed as of yet.
What is her Bishop’s score?
Cervical position - Anterior = +2 Cervical consistency - Soft = +2 Cervical effacement - 60-70% = +2 Cervical dilation - 3-4cm = +2 Fetal station - 0 = +2 Overall = 10 (A Bishop's score of ≥ 8 indicates that the cervix is ripe, or 'favourable' - there is a high chance of spontaneous labour, or response to interventions made to induce labour)
Name one risk and one benefit of using HRT for menopause
risks: breast cancer, VTE, CVS disease, stroke
benefits: relief of Sx, bone mineral density, prevents long term mobidity
When is the first, second and third stage of labour?
- The first stage is from the onset of labour (true contractions) until 10cm cervical dilatation.
- The second stage is from 10cm cervical dilatation to delivery of the baby.
- The third stage is from delivery of the baby to delivery of the placenta.
What are the seven cardinal movements of labour?
- Descent
- Engagement
- Flexion
- Internal Rotation
- Extension
- Restitution and external rotation
- Expulsion
What are the three phases of the first stage of labour?
- Latent phase: From 0 to 3cm dilation of the cervix. This progresses at around 0.5cm per hour. There are irregular contractions.
- Active phase: From 3cm to 7cm dilation of the cervix. This progresses at around 1cm per hour, and there are regular contractions.
- Transition phase: From 7cm to 10cm dilation of the cervix. This progresses at around 1cm per hour, and there are strong and regular contractions.
After giving birth, women require contraception after what day?
Day 21
Adverse effects and one contraindication of injectable contraception (Depo-provera)
Adverse effects
- irregular bleeding
- weight gain
- may potentially increased risk of osteoporosis: should only be used in adolescents if no other method of contraception is suitable
- not quickly reversible and fertility may return after a varying time
Contraindications
- breast cancer: current breast cancer is UKMEC 4, past breast cancer is UKMEC 3
Intrauterine device must be inserted how long after last unprotected sexual intercourse?
- within 5 days of UPSI, or
- within 5 days after the likely ovulation date if a women presents after more than 5 days after last UPSI
Levonorgestrel must be taken how long after last unprotected sexual intercourse?
(asap) within 72 hours after last UPSI
Ulipristal must be taken how long after last unprotected sexual intercourse?
(asap) within 120 hours after last UPSI
The intrauterine device or intrauterine system can be inserted how long after childbirth?
48 hours after childbirth or after 4 weeks
Oestrogen-containing contraceptives should preferably be discontinued 4 weeks before major elective surgery and all surgery to the legs or surgery which involves prolonged immobilisation of a lower limb.
What may be offered as an alternative while the oestrogen-containing contraceptive can be restarted after mobilisation?
Progesterone-only pill
Why should the COCP not be used in the first 21 days postpartum?
risk of VTE
Which form of contraception works by inhibiting ovulation?
COCP
Women need to use effective contraception for how long after their last menstrual period?
- Two years after the last menstrual period in women under 50
- One year after the last menstrual period in women over 50
What are good contraceptive options (UKMEC 1, meaning no restrictions) for women approaching the menopause?
- Barrier methods
- Mirena or copper coil
- Progesterone only pill
- Progesterone implant
- Progesterone depot injection (under 45 years)
Sterilisation
(The combined oral contraceptive pill is UKMEC 2 (advantages generally outweigh the risks) after aged 40, and can be used up to age 50 years if there are no other contraindications)
TIP: It is worth making a note and remembering two key side effects of the progesterone depot injection (e.g. Depo-Provera): weight gain and reduced bone mineral density (osteoporosis). These side effects are unique to the depot and do not occur with other forms of contraception. Reduced bone mineral density makes the depot unsuitable for women over 45 years.
Name some contraindications for the COCP
Examples of UKMEC 3 conditions (disadvantages outweigh advantages):
- more than 35 years old and smoking less than 15 cigarettes/day
- BMI > 35 kg/m^2*
- family history of thromboembolic disease in first degree relatives < 45 years
- controlled hypertension
- immobility e.g. wheel chair use
- carrier of known gene mutations associated with breast cancer (e.g. BRCA1/BRCA2)
- current gallbladder disease
Examples of UKMEC 4 conditions (unacceptable health risk):
- more than 35 years old and smoking more than 15 cigarettes/day
- migraine with aura
- history of thromboembolic disease or thrombogenic mutation
- history of stroke or ischaemic heart disease
- breast feeding < 6 weeks post-partum
- uncontrolled hypertension
- current breast cancer
- major surgery with prolonged immobilisation
The combined oral contraceptive pill (COCP) contains a combination of which hormones?
Oestrogen and progesterone
COCP is licensed up to what age?
50 years
What is ‘withdrawal bleeding’ and ‘breakthrough bleeding’?
- When the pill is stopped the lining of the uterus breaks down and sheds. This leads to a “withdrawal bleed“. This is not classed as a menstrual period as it is not part of the natural menstrual cycle.
- “Breakthrough bleeding” can occur with extended use without a pill-free period.
Name a regime for taking COCP
21 days on and 7 days off
63 days on (three packs) and 7 days off (“tricycling“)
Continuous use without a pill-free period
Side effects and risks of COCP
- Unscheduled bleeding is common in the first three months and should then settle with time
- Breast pain and tenderness
- Mood changes and depression
- Headaches
- Hypertension
- Venous thromboembolism (the risk is much lower for the pill than pregnancy)
- Small increased risk of breast and cervical cancer, returning to normal ten years after stopping
- Small increased risk of myocardial infarction and stroke
COCP reduces risk of which cancers?
Reduced risk of endometrial, ovarian and colon cancer
