Test #1 - Prenatal Factors Flashcards
What is defined as the premature separation of the placenta from the uterus. typically present with bleeding, uterine contractions, and fetal distress?
Abruption Placentae
What is an abnormal absence of menstruation?
Amenorrhea
What is painful menstruation, typically involving abdominal cramps?
Dysmenorrhead
What is difficult or painful sexual intercourse?
Dyspareunia
What is the failure to conceive following twelve months of unprotected intercourse?
Infertility
What refers to the poor growth of a baby while in the mother’s womb during pregnancy. Specifically, it means the developing baby weighs less than 90% of other babies at the same gestational age?
Intra-uterine growth retardation (IUGR)
What are birth defects of the brain, spine, or spinal cord. They happen in the first month of pregnancy, often before a woman even knows that she is pregnant. The two most common defects are spina bifida and anencephaly. In spina bifida, the fetal spinal column doesn’t close completely?
Neural Tube Defects
What is an agent or factor that causes malformation of an embryo?
Teratogens
What are some forms of birth controls?
Abstinence
Natural:
Sympothermal Method, Interruptus
Barrier Methods:
Condoms, Diaphragms, Cervical Caps
Medical:
Oral contraceptives, Vaginal Rings, Patches, Injectsions, Implants Intrauterine devices
Sterilization:
Bilateral tubal ligation, Vasectomy
When is infertility diagnosed?
After 12 months of unprotected sex
What days of the cycle are women most fertile?
11-21
What are some signs of ovulation to teach someone being assessed for infertility?
Wet Slippery Discharge
Higher basal temp
How does a female get checked for infertility?
Thyroid
Diabetes check
Hormonal SA’s
Ultrasounds
Profilactin
Hysterosalpingography
-Dye is injected and goes to uterus and fallopian tubes and shows any physical abnormalities
What are some factors of Infertility?
Waiting til later in life
Prolonged use of BC
Diet
How do we check male/female for infertility? Who is checked first?
Women checked 1st
Then Male
What are some treatment options for infertility?
Medications
Surgical
- May be useful in correcting obstructions
- Therapeutic Insemination
- Invitro Fertilization
Psychological Factors
- Ineffective coping, distress, self-esteem
Why is Folic Acid needed?
To Make DNA/RNA
What are some risks of being Folic Acid Deficiency?
Neural Tube Defects
Spina Bifida
Anencephaly
Meningocele
What foods can you get folic acid from?
Enriched Cereals
Pasta
Bread
Fresh Green leafy veggies
Red and Organ Meats
fish
Poultry
What are some Teratogens that can effect the baby during pregnancy?
Pesticides/Chemicals- work hazards
Radiation = x-rays, radioactive iodine, spills
Infections= Rubella, Syphilis, HSV 2, Toxoplasmosis, Cytomegalovirus
Altitude- women who live in higher altitudes may have increased risk of SGA babies
Medications- Most likely OTC meds.
These can be just as dangerous as scripts. May take teratogenic medication before realizes she is pregnant.
• Greatest risk for gross abnormalities in 1st trimester due to fetal organs developing
What are the FDA drug classifications?
A-Very few drugs in this category
B - Penicillin’s fall into this category
C -Many drugs fall into this category
D -But benefits in certain situations outweigh the risks to fetus
Ex. Tetracycline, Lithium
X -Accutane= acne medication which causes many CNS, facial, and cardiovascular anomalies
“If the mother takes a drug in the D or X category she should be informed of the risks with the drug and also be informed of her alternatives.
A mother taking drugs in other safer categories may need reassurance.
Teratogenic effects most crucial in first trimester However they can also occur in the 2nd andjrd.
What are some caffeine consideration and what does it do during pregnancy?
Caffeine
Decreases iron absorption, predisposing to anemia
No significant data links consumption to birth defects however, heavy consumption (>300 mg/day) has been linked to lowered birth weight
Caffeine intake of >6oo mg/day linked to IUGR, Spontaneous abortion, Increased incidence of cleft palate, and other anomalies are suspected
Constant motion in newborn can often be assessed
What are some things that cigarette smoke does during pregnancy?
Cigarette smoke = cyanide gas.
Decreases amount of O2 consumed by mother
Dec. maternal appetite = poor nutrition
Increase risk of abortion, abruptio placentae, preterm labor, and intrauterine growth retardation (IUGR).
Avoid secondary smoke.
Increased risk of SIDS
Increased risk of resp. illness and chronic resp. disease to newborn
What does alcohol do during pregnancy?
Ethanol passes freely through the placenta
Incidence- Highest in ages 20-40 and teenagers
Effect on fetus in each trimester- 1st alters embryonic development. 2nd effects cell division and growth (all) 3rd CNS development altered growth retardation
C. FETAL ALCOHOL SYNDROME- Incidence in 1-2 live births/1000
- Mental retardation, microcephaly, hyperactivity
- Decreased weight, length, head circumference, persistent postnatal growth deficiency, head circumference and linear growth most effected
- Epicanthal folds, broad nasal bridge, short upturned beaklike nose, abnormally small lower jaw, thin upper lip
- Heart, septal and valvular defects, eyes, kidneys, skeletal system especially joints
