What are the three phases of the menstrual cycle?
Menstrual phase, proliferation phase, and secretory phase
What is the menstrual phase of the menstrual cycle?

- ovum is not fertilized
- average length 4-6 days
- flow 25-60mL
- absent during pregnancy
What is the proliferation phase of the menstrual cycle?
- Days 6-14
- Endometrium thickness increases
- Stimulated by estrogen increase
- Anterior pituitary hormones released
- Stimulates cells producing estrogen
- Initiates ovarian cycle
- Maintained by increased estrogen production
What is the secretory phase of the menstrual cycle?
- Days 15-28
- Follows ovulation
- Influenced by estrogen and progesterone
- Prepares endometrium for gestation
What are all the anatomical sites an ectopic pregnancy can occur in?
- 95% Fallopian tubes
- Abdominal cavity
What are the stages of labor?
- Stage 1 - Dilation; begins with onset of contractions, ends with complete dilation of the cervix
- Stage 2 - Expulsion; begins with complete dilation of the cervix, ends with delivery of infant

What is the ductus arteriosus?
- From the right ventricle, blood enters pulmonary trunk
- Blood shunted from pulmonary trunk into aortic arch through ductus arteriosus
- Closes soon after birth, becomes ligamentum arteriosum in about 3 months

What are the expected changes to mom's cardiovascular system during pregnancy?
- Total % of body water rises
- Blood volume increases 25-40% by 32nd week
- Increased HR
- Supine Hypotensive Syndrome
- EKG changes can included murmurs that go away after pregnancy
What are the expected changes to mom's respiratory system during pregnancy?
- Estrogen causes nasal mucosa edema
- Tidal volume decreases
- VR increases
When does pregnancy become obvious from visibly looking at mom's body?
When does fundal height reach the umbilicus?
When does fundal height reach the xyphoid process?
Full term; when sitting, looks like a shelf
