Q

What system cannot occur during fetal life, it is inhibited to prevent fluid and debris to fill in?

A

Respiratory system. There is no air to breathe in the amniotic fluid. Inhibition of this system prevents filling of fluid and debris (meconium) into the lungs.

Q

Impairment of this organ leads to oligohydramnios?

A

During 4-6 months of pregnancy, fetal kidneys begin to excrete fetal urine which is 70-80% of amniotic fluid. Impairment of fetal kidneys lead to reduced fetal urine > reduced amniotic fluid > oligohydramnios

Q

Normally, how many minutes will the neonate start to breathe?a.) Within one hourb.) Within 30 secondsc.) Within one minuted.) Within one second

A

C.) Within one minute. Loss of placental support so respiratory system starts to function. Neonate starts to breathe. Begins to breathe within seconds. Normal RR within 1 min after birth. Breathing is initiated by sudden exposure to outside world.When the newborn progressively becomes hypoxic, hypercapnic, and acidotic, these provide stimulus to respiratory center and usually causes breathing within an additional minute after birth.

Q

A

c.) has no sufficient fats and protein stores during first 3 daysNeonatal Nutrition:Blood glucose concentration frequently falls the first day =30 to 40 mg/dl of plasma (less than half the normal value)• Has stored fats and proteins for metabolism until mother’smilk can be provided 2 to 3 days later• Special problems: adequate fluid supply to the neonatebecause the infant’s rate of body fluid turnover averagesseven times that of an adult, and the mother’s milk supplyrequires several days to develop.• Physiologic weight loss = decrease of 5 -10 % (as much as20%) within the first 2 to 3 days of life due to fluid loss• After birth liver and muscle glycogen is sufficient only for afew hours

Q

Macrosomal babies common cause?

A

Macrosomal babies (large babies) born to Type II DMmothers▪ The high levels of insulin are believed to stimulate fetalgrowth and contribute to increased birth weight▪ Increased supply of glucose and other nutrients to thefetus may also contribute to increased fetal growth▪ Associated with organomegaly▪ When blood supply is cut off, glucose levels drop, ifinsulin is still high, causing hypoglycemia,▪ Neonates can be at risk for respiratory distress syndromeo In the mother with uncontrolled type I diabetes (caused bylack of insulin secretion), fetal growth may be stuntedbecause of metabolic deficits in the mother and growth andtissue maturation of the neonate are often impaired.

Q

TRUE OR FALSE. During 6th month of pregnancy, diploid state of organism is restored and genetic sex determination occurs.

A

Sex Determination - process of genetic inheritance that sets the gender of anindividual at the moment of fertilization. Remember that at fertilization, there are 2 important genetic events that occur. It is when the male and female nuclei unites:1.) Diploid state of organism is restored and2.) Genetic sex of organism can now be identified. (Male: XY Female:XX)
