exam 1 study guide Flashcards
what is sexual assault
- does not have to include penetration
- sexual act that is forced or coerced without concent
- rape and sexual assaukr are not sexually motivated acts
- MOTIVATED BY AGE, RAGE, AGGRESSION AND THE MOTIVATION TO DOMINATE ANOTHER HUMAN BEING*
- more likely to report to the police if the assailant is a stranger than a partner -
Pre-embryonic development process
- fertilization takes place in the fallopian tube
- union of eggs and ovum forms a zygote ( 46 chromosomes)
- cleaves division continues to form a MORULA (mass of 16 cells)
INNER CELL = blastocyst = EMBRYO AND AMNION
OUTTER CELL = trophoblast = PLACENTA AND CHORION
CHORION: outter most covwr of the embryo (amnion fluid)
what is the pre-embryonic/ embryonic/ fetal stages
- pre embryonic: fertilization through 2nd week
- embryonic: end of 2nd week through 8th week
- fetal stage: end of 8th until birth
MOST CRITICAL TIME: embryonic stage bc during this is when basic structures of major body organs and main external features beguns ti form
how long is the gestation period
- 280 days
- 10 lunar months
- 9 calendar months
NORMAL WEEKS: 37 - 42 weeks
what is the naegle’s rule
last mentrual period + 7 days - 3 months PLUS 1 year = Estimated Due Date
birth defects
- neural tube defects: 6 weeks
- cleft lip: 5-6 weeks
HEART DEVELOPS: 3-8 weeks
functions of the placenta
PLACENTA TAKES OVER THE FUNCTIONS OF LUNGS, KIDNEYS DURING FETAL LIFE ( as a result, large volumes of oxygens are not need by the fetal )
- metabolic function of respiration, nutrition, excretion, storage of nutrients
- makes hormones to contril the physiologic of the mother
- INDUCES THE MOTHER TO BRING MORE FOOD INTO THE PLACENTA
- removing waste products from the fetus
- protection of the fetys from immune attack from the mother
fucntion of Human chorionic gonadotropin ( hCG )
- produced by the placenta during pregnancy
- preserves the corpeus luteum and it’s progesterone prodcution so that the ENDOMETRIAL lining of the uterus is maintained
function of the human placental lactogen ( hPL ) or human chorionic somatomammotropin ( hCS )
- fetal and maternal metabolism
- participates the development of maternal breast for lactatin
- DECREASES MATERNAL INSULIN SENSITIVITY to INCREASE its availability for fetal nutrition
function of the estrogen (estriol)
- stimulates myometrial contractility
- INCREASES THE STASIS OF BILE SALT ( cholestasis of pregnancy ) = pruitis and icterus
- causes blood flow to mouth (blood vessel procreation) = gums more friable and increasea risk of gingivitis
function of progesterone ( progestin )
- smooth muscle relaxation
- causes relaxation of the stomach content. as a result, it causes DECREASE IN MOTILITY AND INCREASE IN ABSORPTION OF MINERALS, NUTRIENTS AND DRUGS = CONSTIPATION
- maintains endometrium
- decreases contractility of the uterus
- stimulates maternal metabolism and breast development
- provides nourishment for early conception
fucntion of the relaxin hormone
- acts with progesterone to maintain pregnancy
- causes relaxation of the PELVIC LIGAMENTS
- softens the CERVIX in preparation for birth
function of the umbilical cord ( A-V-A )
- formed from the amnion
- originates from a connecting stalk
- at WEEK 5, stalk is compressed and forms the narrow part of the umbilical cord*
VEINS: oxygen blood to the fetus
ARTERY: deoxygenated to the placenta
function of the Amniotic Fluid ( 700 - 1000mL )
- too low: oligohydramnios
- too high: hydramnion
- BARRIER TO INFECTION
- maintains constant body temperature
- permits symmetric growth and development
- cushion from trauma
- allows umbilical cord to be free of compression
- promotes fetal movemnt to enhance musculoskeletal development
- INITIALLY DERIVES FROM THE DIFFUSION FROM MATERNAL BLOOD
- large part of this fluid is urine so that can be used to judge the fetal renal function
- fluids from the respiratory and GI tract of the fetus can also enter the amniotic cavity
- the fetus swallows fluid and fluid flows in and out of fetal lungs
BY 11th week: fluid urine into the fluid increasing its volume
Fetal circulation process ( placenta-baby-placenta )
1) the umbilical VEIN carries OXYGENATED blood from placenta to the liver through DUCTUS VENOSUS
2) liver then carries it to the INFERIOR VENA CAVA TO THE RIGHT ATRIUM
3) some of the blood is shunted through the FORAMEN OVALE to the left side of the heart TO THE BRAIN AND UPPER EXTREMITIES
4) rest of the blood travels doen the right ventricle through pulmonary artery
5) small portion of the blood travels to the nonfucntionimg lungs whiles remaining is shunted through the ductus arterious into the AORTA to supply to the rest of the body
3 shunts during fetal life
- DUCTUS VENOSUS: connects umbilical cord to the inferior vena cava
- DUCTUS ARTERIOUSUS: connects main pulmonary ARTERY TO AORTA
- FORAMEN OVALE: anatomic opening between the right left atrium
OXYGENATED BLOOD IS SENT TO VITAL BODY AREAS (heart and brain) whiles first shunting it from less important ones (lungs, liver)
pulse rate and blood pressure changes in pregnancy
- pulse rate increases to 10-15 bpm
- 1st trimester: blood pressure at pre pregnancy levels
- 2nd trimester: DECREASES 5-10 mm Hg
- 3rd semester: returns to pre pregnancy levels
MOST WOMEN ENTER PREGNANCY WITH INSUFFICIENT IRON STORES SO THEY NEED EXTRA DEMANDS
blood volume during pregnancy
INCREASES 1500 mL
- 40-50% abobe pre preg
- RBC: increases to transport the additional oxygen required during pregnancy
- hemoglobin/hematocrit = DECREASES
- WBC: INCREASES in 2nd to 3rd trimesyer

what is reyes syndrome ( aspirin )
acute illness causinf infliteation of fat in the liver
- HYPERAMMONE
- ENCEPHALOPATHY
- INCREASED INTRACRANIAL PRESSURE ( ICP )
- damaged haptic mitochondria disrupt the urea cycle with changes AMMONIA to UREA for excretion

treatment of reyes syndrome
- supportive care
- assisted ventilation if comma
- assesment of ICP
- glasgow coma scale = score of 7,8 or less = coma
- IV GLUCOSE FOR HYPOGLYCEMIA
LABS: blood chemistries, electrolytes, pH, PT
- most important role is parent education. NO ASA (aspirin)
- if they must be on ASA for medical reasons, educate them about reyes syndrome -
