Fertility awareness methods (FAMs)
o Rely on avoidance of intercourse during fertile periods
o FAMs combine charting menstrual cycle with abstinence or other
contraceptive methods
o Natural family planning (period abstinence)
o Calendar rhythm method
o Woman monitors fertile window
o Most fertile 5 days before ovulation until 1 day post-ovulation, so intercourse
is avoided or barrier protection is used cycle days 8-19 (for a regular length
cycle)
o Natural family planning (NFP), standard days method, cycle beads or
software program
o Calendar rhythm method (CRM) is based on premise that ovulation occurs at
day 14 of cycle (plus or minus 2 days)
o Billings method – spinnbarkeit (cervical mucous)
o Advantages
 Natural, noninvasive and inexpensive
o Disadvantages
 Requires extensive initial counseling
 Does not protect against STIs
o Effectiveness
 Couples must practice abstinence
 Low reliability
Barrier methods
o Spermicides
 Chemical barrier, causes the vaginal flora to be more acidic, which is
not favorable for sperm survival
o Condoms, male & female (STI protection)
 Prevent spread of most STIs
 Use only water soluble lubricants with latex condoms
o Diaphragm
 Must be fitted by a provider
 Use with spermicide to increase effectiveness
 Insert up to 6 hr prior to intercourse and leave in place for at least 6
hr after intercourse (no longer than 24 hours at a time)
o Cervical cap
 Insert up to 6 hr prior to intercourse and leave in place for at least 6
hr after intercourse (no longer than 48 hours at a time)

Genetics terms (Genotype, Phenotype, Karyotype, etc.)
o Genotype
 The genotype of a person is her or his genetic makeup. It can also
refer to the alleles that a person has for a specific gene
o Phenotype
 Phenotype is how a person looks (on the outside and inside the body)
due to his or her genes and the environment (for example, having a
certain eye color, being a specific blood type, or being a certain
height). Phenotype also can refer to how a person’s body functions,
for example, whether he or she has a certain disease.
o Karyotype
 A karyotype is an individual’s complete set of chromosomes. The term
also refers to a laboratory-produced image of a person’s
chromosomes isolated from an individual cell and arranged in
numerical order. A karyotype may be used to look for abnormalities in
chromosome number or structure.

39 weeks 0 days and 40 weeks 6 days
 Late term: Pregnancy that has reached between
41 weeks 0 days and 41 weeks 6 days
 Postterm: Pregnancy that has reached 42 weeks
0 days and beyond gestation
 Viability: Capacity to live outside the uterus; about 22 to 25 weeks
gestation are on the threshold of viability


Nagele’s Rule
o Determine first day of last menstrual period (LMP), subtract 3 months, add 7 days
(plus 1 year if needed)
o Most women give birth from 7 days before to 7 days after EDB
Maternal Serum Alpha- fetoprotein- what does it test for? When is it tested?
o Multiple-marker or triple-screen blood test (alpha fetal protein)
o Follow up visit
o Fetal Assessment
o What is an Alpha-fetoprotein (AFP) Test? An AFP test is a test that is mainly used to
measure the level of alpha-fetoprotein (AFP) in the blood of a pregnant person. The
test checks the baby's risk for having certain genetic problems and birth defects. An AFP
test is usually done between 15 and 20 weeks of pregnancy
Common discomforts of pregnancy and interventions
o Nausea and vomiting- eat crackers or dry toast before rising in the morning; avoid
having an empty stomach, avoid spicy, greasy or gas- forming foods. Drink fluids
between meals
o Breast tenderness- wear a supportive bra
o Urinary frequency- empty the bladder frequently, decrease fluid intake before bed,
perform kegel exercises
o UTIs- wipe front to back, avoid bubble baths, wear cotton underwear, avoid tightfitting pants, consume plenty of water, urinate before and after intercourse, void
once you feel the urge, notify the provider if the urine is foul-smelling, bloody or
cloudy
o Fatigue- engage in frequent rest periods
o Heartburn- eat, small frequent meals, do not lie down immediately after eating
o Constipation- drink plenty of fluids, eat a high fiber diet, exercise regularly
o Hemorrhoids- a warm sitz bath, witch hazel pads, and application of topical
ointments
o Backaches- exercise regularly, perform pelvic tilt exercises, use proper body
mechanics, use the side-lying position
o Shortness of breath- maintain good posture, sleep with extra pillows, contact the
provider is manifestations worsen
o Leg cramps- Extend the affected leg with the knee straight and dorsiflex the foot.
Heat and massage may help
o Varicose veins and lower extremity edema- rest with legs and hips elevated, avoid
constricting clothing, wear supportive hose, avoid sitting and standing for long time
periods, not sit with the legs crossed. Sleep in the left lateral position, and exercise
moderately with frequent walking
o Gingivitis, nasal stuffiness, epistaxis- gently brush the teeth, follow good dental
hygiene, use a humidifier, use normal saline nose drops or spray
o Braxton Hicks contractions- position change and walking should relieve the pain. If
contractions increase in intensity and frequency with regularity, the client should
notify the provider (Braxton Hicks contractions are a tightening in your abdomen
that comes and goes. They are contractions of your uterus in preparation for giving
birth. They tone the muscles in your uterus and may also help prepare the cervix for
birth.)
o Supine hypotension- Lie in a side- lying position or semi- sitting position with the
knees slightly flexed

o Monitor placed beneath woman's clothing
o Provide woman with privacy
o Results
 Shows at least two accelerations of FHR with fetal movements of 15
beats/min, lasting 15 seconds or more, over 20 minutes = reactive NST
 15x15 rule over 20 min
 In preterm fetuses (prior to 32 weeks), rate is 10 beats above baseline for 10
seconds in a 20 minute window
 10x10 rule over 20 min
 If reactive criteria are not met, than it is nonreactive
 For example, the accelerations do not meet the requirements (15 x 15 or 10
x 10)
 If data cannot be interpreted, or there was inadequate fetal activity,
than it is unsatisfactory
