What signs of pregnancy are most often noticed by women?
- missed period
- breast tenderness
- fatigue
What are the probable signs of pregnancy?

What are 4 suggestions to help women deal with nausea?
No remedy has been found for this troublesome discomfort but some common tips that may help a woman deal with NV are:
- Eat small amounts of food every 2–3 hours.
- Avoid large meals that over distend the stomach.
– Avoid drinking fluid with meals or over distending the stomach with large amounts of fluid in between meals. - Clear fluids such as apple juice, water, clear tea, ginger ale, and peppermint tea may be easier on the stomach. In general taking herbal teas are not contraindicated; however, there is some evidence to suggest that red raspberry leaf herbal tea may cause uterine contractions.
- Avoid greasy and fatty foods.
- Try not to skip meals or let the stomach become empty.
- Eat dry, starchy snacks, such as arrowroot cookies or melba toast, first thing in the morning or when nausea occurs.
- Avoid getting over tired.
- Sleep in a well-ventilated room and get lots of fresh air.
- Avoid cooking smells that cause nausea.
- Eat what appeals to you.
- Have someone else do the cooking!
- Salty and tart foods may relieve nausea.

- first trimester: week 1 to week 13
- second trimester: week 14 to week - 26
- third trimester: week 27 - week 40
Which weeks of pregnancy is developing embryo most vulnerable to teratogens?
- the first 8 weeks of pregnancy
- rapid cell division, organ system development, and rapid growth occurs in the first 12 weeks of pregnancy
What weeks are considered antenatal care? What are the routine antenatal tests?
- the first trimester: 1-13 weeks
- routine blood tests: CBC, blood type, antibodies and Rh, rubella titer, hepB, STI testing
- ultrasound in the first trimester
- Integrated prenatal screen IPS
- serum integrated prenatal screen SIPS
- nuchal translucency NT
- chorionic villi sampling CVS
- non-invasive prenatal testing NIPT: screens for trisomy 21, 18, 13 —> free for women who are considered high risk
What are 4 factors do you think influence a woman’s decision making in relation to antenatal screening?
- There are many factors that influence which, if any, screening tests a woman decides to pursue during her pregnancy.
- Her age, culture, religious beliefs, past experiences, family history, as well as the availability of tests would all play a role in her decision making.
- It can be very confusing when women have to balance the risk of having a child with a congenital anomaly with the risk of invasive prenatal testing such as amniocentesis.
- There is also a chance of false positives, or uncertain results which may lead to further testing.
- For some women antenatal screening may provide reassurance and for others it may increase their stress.
What is the definition of GTPAL?
- Gravida: total number of pregnancies
- Term: number of pregnancies that carried term
- Preterm: the number of pregnancies that are carried from the age of viability (20 weeks) to before term (<37 completed weeks)
- Abortions: any pregnancy loss prior to the age of viability. This includes spontaneous and therapeutic abortions
- Living: the number of living children at the time of history taking
What is GTPAL for woman pregnant for first time?
- G1 T0 P0 A0 L0
What is the GTPAL for A woman is pregnant for the third time. Her first child was born preterm and died, and her second pregnancy ended at 12 weeks?
- G3 T0 P1 A1 L0
What routine testing is done during the second trimester?
- prenatal visits with care provider once every 4-6weeks
- detailed ultrasound between 18-20 weeks gestation
- screened for gestational diabetes between 24-28 weeks gestation
What routine testing is done during the third trimester?
- prenatal visits every 4-6 weeks until 30 weeks
- prenatal visits every 2-3 weeks between 30-36 weeks
- screen for group B strep (GBS) between 35-37 weeks
- ultrasound ordered if concern about fetal growth and well-being
What are 4 assessment are done during each prenatal visit?
- maternal vital signs: BP may decrease, HR may increase
- urine for presence of ketones/glucose (gestational diabetes) or protein (gestational hypertension)
- weight gain: 2-2.5kg during first trimester, 0.5-1kg per week during second and third trimester
- SFH: symphysis fundal height measurement (after 20 weeks gestation): measurement corresponds to week’s gestation
- overall assessment of women’s adaptation to pregnancy
What are the maternal and fetal risks with being underweight or overweight when pregnancy begins?
- severely underweight women: have preterm labour and birth LBW infants, giving birth to IUGR
- obesity women with hypertension or diabetes: likely develop gestational hypertension, preeclampsia, diabetes during pregnancy, increased risk of c-section
What is Leopold’s maneuver? When would it be performed?
- used to determine the position, presentation, and engagement of the fetus in utero.
- usually performed after 36 weeks by your healthcare provider to determine your baby’s position and estimate their birth weight.
What is the definition of maternal fetal attachment? What 3 factors influence maternal-fetal attachment?
- relate to the emotional tie or relationship that develops throughout pregnancy
- other factors: previous pregnancies, previous losses, use of assisted reproductive technologies, and pregnancy complications, women’s mental health
What does untreated antenatal depression affect (3)?
- increase risk of post-partum depression
- negatively on the couple’s relationship,
- attachment to the infant, and
- may also affect birth outcomes
Which week of pregnancy does the primitive fetal heart starts to beat?
- around 3 weeks of pregnancy
- developmentally complete by the end of the embryonic stage at approximately 8 weeks.
What is the normal heart rate range for full term baby?
- from 110 to 160 beats a minute
- younger fetus has a heart rate that is higher than the more mature fetus.
- This is due to the maturing autonomic nervous system (ANS), which initially is sympathetically driven and causes a higher fetal heart rate
- slower heart rate during fetal sleep
- increased heart rate with fetal movement
Around which weeks is fetal movement felt by mom? What is flutter in abdomen recognized as?
- around 15 to 20 weeks of pregnancy
- flutter senstation is “quickening”
What happens when fetus experience oxygen deprivation?
- it decreases its movements to reduce oxygen demands
- shunts blood supply to the vital organs (heart and brain)
How is the fetal movement count/test assess?
- fetal movement test requires her to lie down on her side for an hour and count the kicks or movements felt.
-Women who do not perceive six movements in an interval of two hours require further antenatal testing and should contact their caregivers or hospital as soon as possible
What shape is a uterus?
- uterus is a pear shaped organ
- amazingly expands from approximately 3” long, 2” wide
- 1” in its non-pregnant state,
- to 500–1000 times its original size to hold a full-term fetus
What is the uterus composed of (4)? Which portion/part does the placenta and fetus develop in?
- upper portion: the fundus
- the body: where the placenta and fetus grow during normal pregnancy
- lower portion: narrower
- the cervix
What is the top of the uterus is called?
- top of the body of the uterus is called the fundus.
- The fundus is the landmark used for measuring uterine and fetal growth in pregnancy once the uterus becomes an abdominal organ around 12–16 weeks
- also the area of the uterus that is palpated when assessing labour contractions and checking the uterus after delivery
What shape is the cervix (part of uterus)?
- cylindrical in shape and
- has an outer and inner opening or os
- outer os: faces the vagina
- internal os: opens into the body of uterus
- in labour, the cervix thins shorten (effacement) and dilates: the outer and inner os becomes one
Where is the isthmus?
- between the body of uterus and cervix
- this dividing area is significant in labour: elongating and thinning out to allow passage of fetus
- in labour: the isthmus is referred as the lower uterine segment
What are the 3 layers that uterus can be divided into?
- inner layer or endometrium
- middle layer or myometrium
- outer layer of the uterus
Why does woman lying on her back cause supine hypotension?
- When a woman is lying on her back the weight of the growing uterus exerts pressure on the inferior vena cava which results in a 25-30% decrease in cardiac output which causes significant hypotension
- Supine hypotension may also result in nausea, dizziness, pallor, diaphoresis and more importantly, can decrease blood supply to the fetus
