How to calculate the weight of an infant from grams into lbs or visa versa.
• 454 grams in 1 pound
Stages of prenatal development.
• Conception
• Zygotic (30 hours)
o Zygote is the fertilized egg
• Embryonic
o 2 weeks after conception
o Embryo has 3 layers of cells
▪ Endoderm (digestive, liver, pancreas)
▪ Mesoderm (skeleton, muscles, heart, and blood vessels)
▪ Ecoderm (skin, nervous system, and sensory organs)
• Fetal
o 8 weeks after conceptions
o Fetus
o Most rapid growth
Critical periods define and when can happen.
• Definition: finite window of opportunity for cells to develop into a tissue/organ
• Most occur in the 1st trimester
• Spontaneous abortion (miscarriages less than 20 weeks)
Which nutrients (vitamins and minerals) are needed during pregnancy and reasons for increase? Be able to
alulate for a food lael hat is eig et for DRI’s if gie the aout eeded for a pregat or latatig
mother.
• To build new cells
o Protein (Increase by 50%)
o Essetial fatty aids; DHA provided y oega 3’s
o Zinc (can cause birth defects)
o Folate and Vitamin B-12
▪ DNA systhesis
▪ Prevent RBC formation-causing folate related anemia
▪ Prevent neural tube deficiencies (spina Bifida, Anencephaly)
o Iron (Increased RBC and fetal iron stores)
• Bone and tooth development
o Calcium and Vitamin D
Optimal wt gains during pregnancy and if given information how to calculate and assess if the pregnant
women is gaining the proper weight.
• 1st trimester is up to 5lbs.
• Underweight 28-40libs
• Normal 25-35 lbs
• Overweight 15-25 lbs
• Obese 11-30 lbs

How to calculate the weight of an infant from grams into lbs or visa versa: 454 grams in 1 pound. Zygotic (30 hours: zygote is the fertilized egg, embryonic, 2 weeks after conception, embryo has 3 layers of cells, endoderm (digestive, liver, pancreas, mesoderm (skeleton, muscles, heart, and blood vessels, ecoderm (skin, nervous system, and sensory organs) Fetal: 8 weeks after conceptions, fetus, most rapid growth. Critical periods define and when can happen: definition: finite window of opportunity for cells to develop into a tissue/organ, most occur in the 1st trimester. Iron (increased rbc and fetal iron stores: bone and tooth development, calcium and vitamin d. Know factors that can affect the rate of aging: heredity. Know how to calculate the number of calories in an alcoholic beverage if given the grams of alcohol: 7kcal/ gram (see in class activity)
