5/24/2023 3

Diagnosis of pregnancy
Pregnancy is mainly diagnosed on the symptoms
reported by the woman and signs elicited by a health
care provider.
Signs and symptoms of pregnancy
These signs and symptoms are divided in to three
classifications; presumptive, probable, and positive.
5/24/2023 4

Possible (presumptive) signs
Breast swelling and tenderness
 Amenorrhea
Morning sickness
Increased frequency of urination/micturation
 Quickening-the first fetal movement felt by the mother.
Constipation and weight gain
Increased skin pigmentation and striae
5/24/2023 5

Probable signs
Uterine enlargement
Positive pregnancy test
Uterine growth
Braxton Hicks contractions- intermittent uterine
contraction during Px.
5/24/2023 6

Positive signs
Visualization of fetus by
•Ultrasound 6 weeks of gestation
•X-ray after 12 weeks of gestation
Fetal heart sounds by
•Ultrasound (at 5th week)
•Fetal stethoscope or fetoscope (20th to 24th weeks
of gestation)
Fetal movements by

Puerpera: a woman who jus gave birth
5/24/2023 12

A. History
Assessing px to determine risk, as well as careful monitoring
of pregnancies with a recognized risk, begins early in the
gestation.
Early and frequent prenatal care allows the care provider to
screen pregnant women and identify pregnancies at risk and
act accordingly.
5/24/2023 13

History
Detailed information concerning past obstetrical
history is crucial because many prior pregnancy
complications tend to recur in subsequent
pregnancies.
5/24/2023 14

Obstetric History
1. Identification-
Name
Age <18yrs and > 35 yrs. – high risk groups
Marital status- unmarried & unsupported – high risk
groups
Address
Religion
Occupation
Date of admission,
Ward, bed number
5/24/2023 15

Obstetric History…cont’d
2. Chief Complaint - Patient may have come for
routine ANC follow-up or
May have a specific complaint e.g. nausea and
vomiting, vaginal bleeding, pushing down pain etc.
5/24/2023 16

3. History of present pregnancy
 Gravidity – all previous pregnancies – term live births,
stillbirths, abortions, ectopic pregnancy or hydatidiform mole.
 Party – Pregnancies that have extended beyond fetal viability
whether the fetus is delivered alive or dead
• Twin/triplet/quadriplet etc delivery is considered as one
parity
• 28 weeks- UK and Ethiopia
• 20 weeks-WHO
 Abortions
 LNMP
5/24/2023 17

Calculate the EDD
• To calculate Expected Date of Deliveery (EDD) –
If we are using European calendar-
Negele’s rule – LNMP – 3 months +7 days
- LNMP + 9 months + 7 days
Ethiopian calendar
LNMP +9 months + 10 days or + (5 if
pagume is 5 or 4 days if pagume is 6) if
Pagume is passed.
5/24/2023 18

Calculate gestational age in completed weeks and days.
 Is calculated as, GA= Date of visit - LNMP
Quickening - 1st time the mother felt fetal movement
Used to date the pregnancy if LNMP is unknown.
• Primigravida – 18 – 20 weeks.
• Multigravida – 16 – 18 weeks.
ANC status should be documented and if not followed the
reason should be sought.
Is the current pregnancy planned, wanted and supported
5/24/2023 19

Case study
W/o Abebech, a 20 years old primigravida mother
come to your clinic for ANC on 13/07/2009 E.c.
Her LNMP was on 04/05/2009 E.c Based on the
given information when will be her expected date of
confinement and gestational age?
5/24/2023 20

Early measurements that correlate well with
gestational age
Measurement Corresponding GA
Date of quickening Primigravida – 18-20 weeks;
Multigravida- 16-18 weeks
Uterine size measurement before 16 weeks during
pelvic exam
Correlates well with the
gestational age
Fundal height felt at umbilicus 20 weeks
First time fetal heart auscultated with fetal
stethoscope
20 weeks
First time fetal heart auscultated with a doppler
device
10 weeks
First day urinary pregnancy test was positive 6 weeks
The above early milestones if present can be used either to confirm the accuracy of
gestational age calculated from LNMP or can be used to estimate gestational age in
mothers with unknown LNMP.
5/24/2023 21

Elaborate the chief complaint
Any complaints during the present pregnancy – eventful
or uneventful ask for danger signs.
Vaginal bleeding
Leakage of liquor
Abdominal pain etc.
Fetal movements decreased or increased? Useful to
assess fetal well-being.
Other negative and positive statement according to the
patients complaints

 Place woman in dorsal recumbent position (supine
with knees flexed) to relax abdominal muscles; with
her arms down.
 Place a small pillow under the head for comfort.
5/24/2023 37

1. Fundal height & Fundal palpation
(1st Leopold Maneuver)
Purpose: determination of Fundal height and what occupies the
fundus.
I. Fundal height measurement
Method: Measure the fundal height in finger breadth or by
centimetre.
Two methods:
a. Finger method:
• Below the umbilicus 1 finger indicates 1 week.
• Above the umbilicus 1 finger indicates 2 weeks.
b. Tape measurement: fundal height measurement in cm from
symphysis pubis to the top of uterine fundus; 1cm = 1wk.
5/24/2023 39

Palpation
Generally fundal height reaches:
12 weeks- fundus slightly above symphysis pubis.
16 weeks- fundus half way between symphysis
pubis and umbilicus.
20 weeks- fundus at umbilicus
36 weeks- fundus at xiphisternum.
5/24/2023 41

Cont’d…
II. Fundal palpation
Purpose: to know what occupies the fundus.
Method: - using two hands, palpate on either side of the
fundus and feel for the fetal part lying in the fundus.
If it is head: firm, hard, and round, that moves
independently of the body (ballottable mass).
If it is breech: soft, irregular, bulky mass
5/24/2023 42

2. Latéral Palpation: (2nd Léopold Maneuver)
•Purpose: to know lie and side of the back
Lie: (the long axis of the fetus in relation to that
of mother) it may be longitudinal, transverse,
and oblique lie.
Back of the fetus: to auscultate FHB, b/s FHB
at 20 weeks well heard on the back.
5/24/2023 45

Cont’d…
Method: One hand is used to steady the uterus on
one side of the abdomen while the other hand
moves slightly on a circular motion from top to the
lower segment of the uterus to feel for the fetal
back and small fetal parts.
Use gentle but deep pressure. Note the regularity;
the regular side is the back.

uterine pole it may be cephalic, breech, or
shoulder Presentation.
5/24/2023 50

4. Paw lick’s Grip: (4th Leopold’s Maneuver)
Purpose:
To determine engagement of presenting part.
To know presentation & descent of fetal head.
• Engagement: when the biparietal diameter of the fetal head
passes through the pelvic brim.
• Method: Using thumb and finger, grasp the lower portion of the
abdomen above symphysis pubis, press in slightly and make gentle
movements from side to side and feel the occiput and sinciput, note
which is lower.
5/24/2023 52

Cont’d…
• The presenting part is engaged if it is not movable.
• It is not yet engaged if it is still movable.
• The head is engaged when the largest the transverse
diameter (bi-parietal diameter) has passed the pelvic brim.
• It can be diagnosed on palpation, when two fifth of the head
or less is felt above the brim.
• The head should be engaged in a primigravida after 36
weeks.
