FH: Antepartum Nursing: Study Notes
Antepartum Nursing: Study Notes
Overview: Antepartum vs Intrapartum
Antepartum period: from conception (pregnancy confirmation) through delivery.
Intrapartum period: the time of labor and delivery.
Nursing goals in antepartum care:
Build trust with the patient.
If in a clinic setting: frequent visits, lab work, prenatal testing, education.
Signs and Symptoms of Pregnancy
Classification of signs:
Presumptive signs: may suggest pregnancy but are not confirmation.
Examples: missed period or irregular menses, fatigue, nausea/vomiting, breast changes, skin changes.
Probable signs: more suggestive but not definitive; require provider assessment.
Examples: Hegar sign (softening of the uterus), Goodell sign (softening of the cervix).
Cervical color changes observed by the care provider; Chadwick sign (deep violet-blue cervix).
Ballottement (feeling of fetus or movement when cervix is checked).
Abdominal enlargement, cramping, contractions, or a home pregnancy test positive.
Positive signs: definitive confirmation of pregnancy.
Examples: fetal heartbeat detectable, ultrasound visualization of the fetus.
Estimating due date uses the last menstrual period (LMP) and Naegele’s rule:
Naegele’s rule (as taught in lecture): subtract 3 months from the LMP, add 7 days, and adjust the year if necessary.
Formula:
Note: spelling in lecture was “Niguel’s rule”; standard term is Naegele’s rule.
Common obstetric terms you’ll encounter:
Nulligravida: never been pregnant.
Primigravida: pregnant for the first time.
Multigravida: has been pregnant two or more times (lecture notes say at least third-time).
Primip (primipara): has given birth once or is about to give birth; gestation around 20 weeks (per lecture).
Multip (multipara): two or more pregnancies of at least 20 weeks gestation.
Gravida/Para definitions:
Gravida: total number of pregnancies.
Para: birth of a fetus of at least 20 weeks gestation (alive or deceased).
TPAL framework (to categorize pregnancy outcomes):
T = Term births (38–42 weeks)
P = Preterm births (<37 weeks)
A = Abortions or miscarriages prior to 20 weeks (elective or spontaneous)
L = Living children
Fetal Development: Stages and Structures
Fetal development timeline (general stages):
Preembryonic stage: fertilization, cell division, genetics; formation of embryo and amniotic sac begins.
Embryonic stage: organ development; membranes form; amniotic fluid forms; yolk sac forms.
Fetal stage: growth and maturation of organs and structures; amniotic fluid expands to protect the fetus.
Amniotic fluid and sac:
Amniotic fluid helps cushion the fetus and the umbilical cord.
By term, amniotic fluid reaches about (approximate)
Placenta and umbilical cord:
Placenta forms and connects mom and baby; delivers nutrients and oxygen; transports waste.
The umbilical cord typically has two arteries and one vein.
Blood does not mix between mother and fetus.
Placenta also produces hormones, supporting pregnancy (e.g., progesterone).
Wharton’s jelly:
Protective substance surrounding the fetal vessels within the umbilical cord.
Hormonal support during pregnancy:
Progestin maintenance may be required in some pregnancies; monitoring of human chorionic gonadotropin (HCG) levels may be used to monitor pregnancy viability.
Placenta as a lifeline for nutrients, oxygen, and hormonal support throughout gestation.
Fetal Development: Visual Progression and Anatomy
Weeks of development progress from early pregnancy to later stages (illustrative images shown in course materials).
Transitions from early to more defined fetal features as weeks advance.
In clinical practice, clinicians frequently compare fetal development findings to gestational age to assess growth and well-being.
Assessments and Monitoring During Prenatal Care
First prenatal visit:
Counseling, screening, and lab work.
History and physical (H&P).
Follow-up visits:
Typically every 4 weeks until 28 weeks, then more frequently toward the end of pregnancy.
Nursing assessments at visits:
Fundal height measurement (in centimeters) from the top of the uterus to the pubic symphysis; should roughly correspond to weeks of gestation.
Maternal weight tracking.
Urine analysis via dipstick: check for glucose (sugar) and protein to screen kidney function and risk for gestational diabetes or hypertension.
Vital signs.
Fetal heart rate: assessed with a Doppler ultrasound for spot checks.
Visualization of fetal growth and development via ultrasound, including potential transvaginal ultrasound early on and external ultrasound later.
Routine laboratory tests (OB panel and beyond):
CBC (complete blood count)
Blood type and Rh with antibody screening
HBsAg (hepatitis B surface antigen) and Rubella immunity
Group B Streptococcus (GBS) screening
Urinalysis (UA)
Glucose tolerance test (GTT)
Other infectious screening: TORCH screen, Pap smear, and vaginal/cervical cultures for syphilis, chlamydia, gonorrhea, and possibly herpes.
TORCH screen (Toxoplasmosis, Others, Rubella, Cytomegalovirus, Herpes) – done via blood tests to assess maternal/fetal infection risk.
A blood-draw worksheet may be used to organize maternal screening results.
Imaging:
Spot checks of fetal heartbeat with Doppler.
Transvaginal ultrasound for growth assessment early in pregnancy.
External ultrasound as pregnancy progresses.
Education and counseling materials:
Offices commonly provide handouts or pamphlets covering nutrition, danger signs, and prenatal care expectations.
First Trimester: Common Symptoms and Hormonal Effects
Common early-pregnancy discomforts (first ~3 months):
Fatigue, breast tenderness, constipation, nasal congestion/epistaxis, gum bleeding.
Cravings and aversions; vaginal discharge due to hormonal changes.
Elevated human chorionic gonadotropin (HCG) levels contributing to nausea and vomiting.
Nutritional and supplementation needs:
Prenatal vitamin recommended; iron supplementation may be added depending on labs; stool softeners may be prescribed to prevent constipation.
Some clinicians may add extra folic acid beyond what’s in the prenatal vitamin to support neural tube development.
Diet and food safety:
Emphasize a healthy diet with fruits, vegetables, fiber, vitamins, and minerals.
Protein-rich sources; limit fish high in mercury; avoid raw or unpasteurized dairy products; avoid processed foods like deli meats and hot dogs due to infection risks (e.g., listeria).
Non-nutritive cravings (pica) may occur (e.g., dirt, clay, laundry starch, ice, coffee grounds, paint chips); advise avoidance.
Weight gain guidance:
Varies with maternal BMI; general ranges provided but personalized recommendations are common in practice.
Second and Third Trimesters: Symptoms, Risks, and Adaptations
Common later-pregnancy discomforts:
Backache, leg cramps, varicose veins, hemorrhoids, increased gas, shortness of breath as uterus enlarges.
Braxton Hicks contractions (practice contractions) and occasional cramping.
Diaphragm elevation leading to breathing changes, heartburn, indigestion.
Edema or swelling may occur.
Ongoing fetal monitoring and growth assessment:
Monitor fetal movement and growth patterns; position of fetus can impact delivery and maternal comfort.
Danger signs (important to educate patients):
Early pregnancy: infection (e.g., UTI), severe vomiting with risk of dehydration, fever, chills, cramps, bleeding; contact office for concerns.
Later pregnancy: gush of amniotic fluid, vaginal bleeding, abdominal or back pain, persistent headaches, visual disturbances, spots before the eyes, excessive swelling, epigastric pain (possible hypertension).
Other warning signs: fever, dysuria, symptoms suggestive of diabetes (fruity breath, dry skin, polydipsia, polyuria), dizziness, not feeling the baby move as much as usual; if dizzy or pale, advise side-lying position and seek evaluation.
Adapting to pregnancy:
Physical and psychological changes covered in course texts (textbook and ATI resources); recommended to review these chapters for deeper understanding.
If time allows, class activities may discuss adaptations in detail.
Nutrition, Lifestyle, and Health Maintenance During Pregnancy
Nutritional foundations:
Continue prenatal vitamins; ensure adequate iron and folic acid intake; fiber and hydration to prevent constipation.
Emphasize a balanced diet with fruits, vegetables, whole grains, and lean proteins.
Avoid foods with high mercury levels; avoid raw milk and unpasteurized dairy products; avoid processed deli meats and hot dogs unless heated until steaming hot.
Lifestyle considerations:
Maintain regular prenatal visits and follow provider guidance for supplements and lifestyle choices.
Be vigilant about danger signs and when to contact the healthcare provider.
Practical Seminal Points for Clinical Practice
The placenta and pregnancy reliance:
Placenta acts as a lifeline, hormone producer, and nutrient/oxygen transfer organ; maternal-fetal blood does not mix.
Umbilical cord anatomy:
Two arteries and one vein; Wharton’s jelly protects these vessels.
Imaging and fetal assessment:
Use of Doppler for fetal heart rate checks; transvaginal ultrasound early in pregnancy; external ultrasound later for growth and anatomy.
Key terminology to memorize for exams and clinical use:
Naegele’s rule for EDC calculation:
TPAL categories and definitions for obstetric history.
Gravida/Para definitions and the common abbreviations (GTPAL when expanded).
Quick Reference: Common Routine Screenings Included in Prenatal Care
OB panel components typically include:
CBC, blood type and Rh with antibodies, hepatitis B surface antigen, rubella immunity, GBS status, urinalysis, and 1-hour glucose tolerance test (or confirm with 2- or 3-hour test if needed).
Infectious disease screening and immunization checks:
Pap smear or Pap test at the initial prenatal visit, plus vaginal/cervical cultures for syphilis, chlamydia, gonorrhea, TORCH screen, rubella testing, and herpes testing as indicated.
Counseling and education:
Provide patient handouts on danger signs, nutrition, and prenatal care expectations; reinforce to contact the office if concerning symptoms arise.
Final Takeaways
Antepartum care combines relationship-building, repeated monitoring, education, and early identification of potential complications.
Understanding gestational age concepts, fetal development stages, and key obstetric terms (G/P/TPAL) is essential.
Regular screening labs and fetal assessments guide care to optimize outcomes for mother and baby.
Nutrition and safe-living practices during pregnancy are critical for fetal development and maternal health.
Awareness of danger signs by trimester ensures timely medical attention and reduces risks.
