defined as the number of times that a woman has been pregnant.
Gravidity/ Gravida
has not given birth previously (regardless of outcome).
Nulliparous woman (nulli)
first pregnancy
primigravida
has given birth once
Primiparous woman
had been pregnant more than once
Multigravida
given birth more than once
Multiparous woman (multip)
woman who has already delivered five or more infants who have achieved a gestational age of 24 weeks or more, and such women are traditionally considered to be at higher risk than the average in subsequent pregnancies.
Grand multipara
has been pregnant five times or more
grand multigravida
has delivered seven or more infants beyond 24 weeks’ gestation.
great grand multipara
defined as the number of times that she has given birth to a fetus with a gestational age of 24 weeks or more, regardless of whether the child was born alive or was stillborn.
parity
most commonly used method for determining the Estimated date of delivery,as it is the most accurate
Naegel’s Rule
Add 12 for first three months:
Jan: 1+12=13
Feb: 2+12=14
March: 3+12= 15
-3 +7 +1
-31 (most commont number of months)
period of time between conception and birth. During this time, the baby grows and develops inside the mother’s womb.
common term used during pregnancy to describe how far along the pregnancy is. It is measured in weeks, from the first day of the woman’s last menstrual cycle to the current date.
A normal pregnancy can range from 38 to 42 weeks.
Infants born before 37 weeks are considered premature.
Infants born after 42 weeks are considered postmature.
Gestational Age
add Months then divide 7
if answer has point x 7
measure of the size of the uterus used to assess fetal growth and development during pregnancy. It is measured from the top of the mother’s uterus to the top of the mother’s pubic symphysis.
fundal height or mcdonald’s rule
through LMP
• using McDonald’s Rule
fundal height in cm x 2/7 = AOG in months
fundal height in cm x 8/7 = AOG in weeks
estimating fetal length (2nd trimester)
A full term newborn’s length ranges from 18-22 inches, 19 to 21 inches or 48 -52 cm. an accepted average length is 50 centimeters.
Haase’s Rule
From 1to 5 lunar months, square the month of pregnancy (to square a number is to multiply it by itself)
(months of pregnancy) = fetal length
Problem 1. how long is a 4 month old fetus?
Solution 4 x 4 = 16 cm
From 6-10 lunar months, multiply the month by 5.
(month of pregnancy) x 5 = fetal length
Problem 1. how long is 7 month old fetus?
Solution: 7x 5 = 35 cm
calculates the estimated age of gestation (aog) of a fetus depending on the the height of the fundus.
It does not use a numerical height value to compute gestational age, but landmarks.
Bartholomew’s rule
12wks.- palpated above the symphysis pubis.
• 16 wks.- the fundus reaches midway bet. the symphysis pubis and the umbilicus.
• 20-22 wks.- the fundus is located approximately at the umbilicus.
• 24wks.- 2 fingers above the umbilicus
32 wks.- midway bet. umbilicus and xiphoid process.
36wks. - the fundus reaches its highest level at the xiphoid process.
40 wks. - the fetal head descend into the pelvic cavity. Descent of the fetal head is called lightening
used to estimate the weight of the fetus in grams. To determine this, a standard formula is used.
Johnson’s rule
Formula: fundic height in cm - n x k
k is constant, it is always 155
n is 12 if the fetus is not yet engaged. Above the level of the ischial spine - not yet engaged
It is 11 if the fetus engaged. (37 weeks) Below the level of the Ischial spine - engaged
Example:
A fundic height of 28 cm, and the fetus is not engaged.
28cm-12x155=16x155= 2480 grams
