Study Notes

Uterus Changes

Length increases from 6.5 to 32 cm
Depth increases from 2.5 to 22 cm
Weight increases significantly, ranging from 50 to 1000 g
Volume expands from 2 mL to over 1000 mL
Wall thickness increases from 1 to 2 cm during the beginning of pregnancy
Width expands from 4 to 24 cm

Cervical Changes

Increased vascularity and fluid between cells
Endocervix glands produce thick mucus (operculum) that blocks the cervical canal, preventing bacterial entry into the uterus

Vaginal Changes

Walls soften and become more elastic
pH shifts from 7 to 4 or 5, creating an acidic environment, which inhibits bacterial growth, however, may favor yeast infections like Candida albicans

Ovarian Cycle Changes

Ovulation stops during pregnancy
Corpus Luteum produces progesterone until the placenta takes over, sustaining hormones during the placenta's formation
Corpus Albicans is the remnant or scar left after the corpus luteum regresses

Breast Changes

Size increases due to glandular and fatty tissue growth
Areola diameter increases
Vascularity increases, making the areola darker due to increased blood flow
Estrogen causes growth and development of breast tissue
Montgomery Tubercles: Small bumps on the areola that secrete a lubricating substance
Colostrum, a thin, yellowish fluid, is produced by the breasts during pregnancy

Integumentary System Changes

Striae Gravidarum (stretch marks) occur as a result of skin stretching
Linea Nigra, a dark line, develops from the pubic bone to the umbilicus
Melasma ("Mask of Pregnancy"), brownish pigmentation on the face, is caused by increased estrogen levels
Telangiectasia (Spider Angiomas) are tiny, branched blood vessels appearing on the skin
Palmar Erythema is redness of the palms of the hands

Respiratory System Changes

Increased Oxygen Consumption to meet fetal needs
Increased Tidal Volume and Respiratory Rate to compensate for the increased oxygen demand
Dyspnea may occur in later pregnancy stages due to the uterus pressing on the diaphragm
Increased Sensitivity to Temperature Changes

Cardiovascular System Changes

Increased Blood Volume to provide adequate blood flow to the placenta and fetus
Increased Cardiac Output to accommodate the increased blood volume
Heart Rate increases slightly
Blood Pressure may decrease in the first trimester but usually returns to normal by the second trimester
Supine Hypotension Syndrome: Compression of the inferior vena cava restricts blood flow from the lower extremities, potentially leading to dizziness or fainting while lying flat
Increased Risk of Varicose Veins and Hemorrhoids due to the pressure of the uterus on the veins in the legs and rectum

Gastrointestinal System Changes

Slower Peristalsis can lead to constipation
Nausea and Vomiting are common in the first trimester
Heartburn may occur as the uterus presses on the stomach
Increased Appetite due to the increased metabolic demands of pregnancy
Hemorrhoids can occur due to the pressure of the uterus on the veins in the rectum

Urinary System Changes

Increased Frequency of Urination due to the pressure of the uterus on the bladder
Increased Urinary Tract Infections (UTIs) due to changes in the urinary system

Skeletal System Changes

Ligament Relaxation to prepare the pelvic bones for childbirth
Increased Lumbar Lordosis, a curvature of the lower spine
Carpal Tunnel Syndrome due to swelling in the hands and wrists
Relaxin, a hormone produced by the ovary, relaxes pelvic joints and ligaments

Diagnosis of Pregnancy

Presumptive Signs

Amenorrhea (absence of menstruation)
Frequent urination
Melasma ("Mask of Pregnancy")
Breast changes
Fatigue
Striae gravidarum (stretch marks)
Nausea and vomiting
Linea nigra (dark line on abdomen)
Quickening (fetal movement)

Probable Signs

Laboratory Tests: Serum and urine tests positive for hCG (human chorionic gonadotropin)
Evidence of a gestational sac on ultrasound
Ballottement: Rebound of the fetus when the examiner taps the uterus
Chadwick’s Sign: Bluish discoloration of the cervix and vagina due to increased blood flow
Hegar’s Sign: Softening of the lower uterine segment
Goodell’s Sign: Softening of the cervix
Braxton Hicks Contractions: False labor contractions

Positive Signs

Fetal Outline on Ultrasound
Demonstration of Fetal Heartbeat Separate From Mother's
Fetal Movement Felt by Examiner

Common Discomforts in Pregnancy and Nursing Interventions

Breast Tenderness: Supportive bra, warm clothing, and avoiding cold drafts
Constipation: Increased dietary fiber, water intake, and regular bowel movements
Nausea and Vomiting: Small frequent meals, dry crackers before rising, and avoiding greasy foods
Fatigue: Encourage rest and sleep
Leg Cramps: Stretching and leg elevation
Varicose Veins: Rest with legs elevated, support stockings, and exercise
Hemorrhoids: Knee-chest position and cold compress
Frequent Urination: Avoid restricting fluids and monitor for UTI signs
Shortness of Breath: Elevate head while sleeping and limit activities
Backache: Pelvic rocking exercises and proper posture
Edema: Rest with legs elevated, avoid tight clothing, and reduce contributing factors
Headache: Rest, cold compress, and prescribed analgesics
Braxton Hicks Contractions: Changing positions, drinking water, and taking warm baths

Lightening

The sensation of the baby "dropping" into the pelvis, usually occurring a few weeks before labor
Reduces pressure on the diaphragm, but increases pressure on the bladder.
