or isthmus
Presumptive Signs (subjective)
- fatigue
- breast tenderness/ enlargement
- nausea/vomiting
- amenorrhea
- urinary frequency
- uterine enlargement
- quickening
- hyperpigmentation of skin
Probable Signs (objective)
- Braxton hicks
- positive pregnancy test
- abdominal enlargement
- ballottement ( press the cervix and you can feel the baby go up and down)
- Goodell, Chadwick, Hegar signs
Types of pregnancy test
- stick (yes or no)
- blood (quantitative/ numbered)
3 positive signs of pregnancy

- Auscultation of fetal heart via doppler ( hearing)
- Fetal movement by clinician ( feeling)
T/F
A positive pregnancy test is a positive sign of
pregnancy.
False
Reproductive Adaptations
UTERUS: estrogen causes the uterus to grow, increasing oxytocin receptors and contractions. Hegar sign. 20 weeks fundal height at the umbilicus can determin gestational age until 36 weeks
CERVIX: Goodell sign, mucus plug, Chadwick sign, ripening 4wks before birth
VAGINA: lengthen vagina, secrete leukorrhea, increase vascularity
OVARIES: enlargement until 12-14wk gestation, stop ovulation
BREAST: increase size, nipple size (erect and darker), colostrum production
Lightning (mothers belly drop)
Primate: 1st baby ( 2 weeks before due)
Multip: more than 1 baby. (4 weeks before due)
Orthostatic Hypotension
(mother shouldn’t lay on her back)
The pressure of the uterus on the inferior vena cava.
- light headiness
- dizziness
- getting up too fast
- blurry vision
- fainting
Gastrointestinal System adaptions
- Gums: swollen, friable, hyperemic
- ptyalism: excessive spitting
- dental problems: gingivitis
- constipation, hemorrhoids
- heartburn
- nausea/vomiting (diclegis drug for 1st trimester)
Cardiovascular Adaptations
- increase blood supply ( 50%more prepreg level)
- increased output, venous return, HR
- Increase in number of RBCs; plasma volume > RBC
leading to HEMODILUTION (physiologic anemia) MORE PLASMA THAN RBC (PEPSI & ICE) - Increased clotting factors (hypercoagulable state) due to iron, fibrin, and plasma levels.
When assessing a pregnant woman, which of
the following would the nurse expect to find?

Respiratory Adaptations
- Diaphragmatic breathing
- increase oxygen
Renal/ Urinary adaptations
Increase in glomerular filtration rate; increased
urine flow and volume
Musculoskeletal system Adaptations
- Shifting balance
- waddle gait
- lordosis
- relaxing joints and pubis symphysis
Integumentary Adaptions
- hyperpigmentation
- linea nigra ( line on the belly)
- Striae Gravidarum ( stretch marks)
- varicose veins/ spider veins
- increase nail growth , decline in hair growth
- palmar erythema (red hands)
Endocrine system adaptations
- Thyroid gland: slight enlargement; increased activity;
increase in BMR. Pregnancy induced hyperthyroidism
-Pituitary gland: enlargement; decrease in TSH, GH;
inhibition of FSH and LH; increase in prolactin, MSH;
gradual increase in oxytocin with fetal maturation - Pancreas: insulin resistance due to hPL and other
hormones in second half of pregnancy (see Box 11.2) - Adrenal glands: increase in cortisol and aldosterone
secretion - Prostaglandin secretion
- Placental secretion: hCG, hPL, relaxin, progesterone,
estrogen (see Table 11.3)
T/F
Oxytocin is a hormone secreted by the anterior
pituitary gland.
False
Nutrition while pregnant
- not eating for two (only need 300 more calories) breast feeding moms need 500 calories more)
- vitamins/ folic acid
- dietary considerations, like vegetarian, vegan, gluten-free, pica, lactose intolerance.

o First trimester: 5 lb
o Second and third trimesters: +1 lb/wk
- BMI >25: 15 to 25 lb

Maternal Emotional Respinses
- Ambivalence: mixed feelings
- Introversion: focusing only her own body and baby
