The Prenatal Assessment
Introduction Introduction The objective of this chapter is to enhance understanding of the complexities and challenges involved in providing prenatal nursing care. Each prenatal visit offers an opportunity for the nurse to provide a comforting, supportive environment for the expectant woman and her family members. During these visits, educational needs can can be discussed, reassurance can be provided, and problems or potential problems can be discovered.
Promoting maternal physical, psychological, and spiritual health and facilitating maternal empowerment are key to promoting and enhancing fetal well-being and a positive pregnancy outcome. throughout pregnancy are explored.
Goals that guide nursing careof the prenatal patient
•To recognize deviations from normal• To provide individualized, evidence-based care• To provide culturally appropriate prenatal educationdesigned to meet the patient’s learning style and needs• To empower women to become actively involved in their pregnancy by being informed recipients and shared decision makers.
Despite tremendous improvements in perinatal care, women still die in childbirth and it is not unrealistic for a woman to fear for her own safety. The World Health Report “Make Every Woman and Every Child Count” (World Health Organization 2005) focuses on making pregnancy safer and asserts that reaching this goal centers on providing excellent antenatal care and constructing societies that support pregnant women. Antenatal care must be consistently accessible and responsive while incorporating patient-centered interventions, thereby removing barriers that prevent access to care.
Prenatal Visit timePrenatal Visit time
Prenatal care usually begins in the first trimester of pregnancy, when the patient is seen every 4 weeks until she reaches 28 to 32 weeks’ gestation. At that time, the appointments are changed to visits every 2 weeks and then occur weekly from 36 weeks of gestation until birth.
Although this schedule has to some extent become the “standard of care,” it has not been possible to substantiate the necessity for such frequent visits. Interestingly, the number of total prenatal visits varies tremendously from as few as 3 to 4 visits (less number) for low-risk women in some European countries to 14 or more visits for women with uncomplicated pregnancies in the United States (Partridge & Holman, 2005).
CARE PrinciplesCommunicationThe exchange of information by speaking, writing, or using a common system of signs or behavior or written messageAdvocateOne who argues for a cause; a supporter or defenderOne who pleads in another’s behalf; Advocates for abused children and spousesRespectTo show consideration or thoughtfulness in relation to somebody or somethingEnableTo provide somebody with the resources, authority, or opportunity to do something To make something .
Choosing a Pregnancy Care Choosing a Pregnancy Care ProviderProvider
One of the early decisions the patient (and partner) makes concerns choosing a care provider.
It is recommended that every patient arrange an appointment with a chosen care provider (obstetrician, family practice physician, certified nurse midwife) to discuss the management of pregnancy and childbirth as early as possible within the first trimester.
The woman may seek childbearing care from an obstetrician, a family practice physician, or a certified nurse midwife. Approximately 90% of pregnant women choose anobstetrician as the primary care provider.

Presumptive Signs Of Pregnancy
The subjective signs of pregnancy are the symptoms that the patient experiences and reports. Because these symptoms may be caused by other conditions, they are the least indicative of pregnancy. In combination with other pregnancy symptoms, the following presumptive signs may serve as diagnostic clues:1.Amenorrhea2.Nausea and vomiting (morning sickness)3.Frequent urination4.Breast tenderness5.Perception of fetal movement (quickening)6.Skin changes(striae gravidarum)7.Fatigue
PROBABLE SIGNS OF PREGNANCY
1. Abdominal enlargement 2. Hegar sign (softening of the lower uterine segment) may also
be caused by pelvic congestion.3. Goodell sign may also be caused by infection, hormonal
imbalance or pelvic congestion.4. Chadwick may also be caused by pelvic congestion, infection,
or a hormonal imbalance.5. Braxton–Hicks sign also be associated with uterine
leiomyomas (fibroids) or other tumors.6. Positive pregnancy test may occur from certain medications,
premature menopause, choriocarcinoma 7. Ballottement may be due to uterine tumors or cervical polyps
instead of the presence of a fetus.
The positive indicators of pregnancy are attributable only to the presence of a fetus:
1. Fetal heartbeat2.Visualization of the fetus3. Fetal movements palpated by the examiner
positive signs of pregnancy
Naegele’s Rule is used to calculate the Expected Date of Birth (EDB) – Expected Date of Delivery (EDD) This calculation is based on the first day of the woman’s last normal period. 7 days are added to the LMP and 3 months subtracted and where necessary a year added.
The Pregnancy Classification System
Gravidity: relates to the number of times that a woman has been pregnant, irrespective of the outcome. nulligravida :a woman who has never experienced a pregnancy. primigravida: is a woman pregnant for the first time. A multigravida: pregnant for the third (or more times). Parity: pregnancies carried to a point of viability (500 gat birth or 20 weeks of gestation), regardless of the outcome.For example, “para 1” indicates that one pregnancy reachedthe age of viability. It is important to note that the term parity (or “para”) denotes the number of pregnancies, not the number of fetuses/babies, and does not reflect whether the fetuses/babies were born alive or stillborn.Some facilities use a digital system (i.e., GTPAL) for recording the number of pregnancies and their outcomes.

The Prenatal Physical Examination
The patient should be given adequate private time to preparefor the examination and encouraged to void if needed (a urine specimen may also need to be collected). Before conducting the physical examination, it is essential to properly prepare the environment. The room should be warm, with a cover for the patient and a gown for her to wear. Ensure privacy for the patient, such as a “Do not disturb exam in progress” sign affixed to the closed door.
