leucine
lysine
methionine
phenylalanine
threonine
tryptophan
tyrosine
valine

24
Q

Why is taurine especially important for infants

A

-cell membrane protector
-conjugates bile acids
*if infant has a deficiency, vision, hearing and fat absorption is affected

25
26
What happens to an infant if they have an essential fatty acid deficiency
-increased metabolic rate -neurocognitive development is delayed -failure to grow -hair loss -dry flaky skin -thrombocytopenia -impaired wound healing
27
What are the 2 essential polyunsaturated fatty acids(PUFA)
linoleic acid(omega-6 fatty acid) -> arachidonic acid linolenic acid(omega-3 fatty acid) -> docosohexaenoic acid
28
How long does the WHO and American Academy of Pediatrics recommend exclusive breast feeding
they recommend exclusive feeding for the first 6 months of life *recommend through 12 months if appropriate for parent/child
29
What is the healthy people goal 2030 for exclusive breastfeeding
that 42.4% will breast feed exclusively for the first 6 months of the infants life
30
What are the benefits of breast feeding for the infant
-optimal nutrition source -improved parent-child binding -decreased risk of infant infections -decreased risk of SIDS, diabetes, leukemia, obesity, hyperlipidemia, eczema, celiac disease, IBD -POSSIBLE enhanced performance on cognitive development
31
What are the benefits of breast feeding for the parent
-improved bonding -decreased postpartum bleeding -decreased menstrual blood loss -increased spacing between children -earlier return to pre-pregnancy weight -decreased risk of breast and ovarian cancer -decreased risk of RA -decrease risk of osteoporosis -no money spent on formula
32
What are the contraindications to breast feeding
1. HIV infection(can be passed thru breast milk) 2. infant galactosemia 3. parental untreated TB 4. parental human T cell lymphotropic virus 1 or 2 infection 5. presence of a herpes simplex lesion on the breast 6. parental use of contraindicated medications
33
Why is cow milk not for infants under the age of 1 year?
too much protein and not enough iron
34
Why should evaporated milk be avoided
Not made for general nutrition
35
Why might goat milk be better than cow milk for children
the fat is digested more easily than cow milk however must be fortified with folate, iron and vit D
36
What are the 4 types of infant formulas
premature newborn infant/toddler specific health conditions
37
What are the 3 base types of infant formula
milk-based soy protein casein hydrolysate
38
What are the formulations available
concentrated liquid powder ready-to-feed
39
Why is the sterility of the formula important
the infants immune system isn't fully developed and the stomach acid isn't as strong so can't destroy any contaminants
40
What type of formula should preemies and immunocompromised infants receive
only receive ready to feed or liquid *mfg to be sterile
41
Are powdered formulations guaranteed to be sterile
no, they are not guaranteed or required to be sterile and should undergo sterile prep before feeding
42
How can formulas be made to be more concentrated
-vary the amount of water added *ONLY CONCENTRATE WITH MEDICAL ADVICE
43
What are modular macronutrient components
protein, carbohydrates, fat and combinations of the above that can be added to either human milk or infant formula to fortify formula *only do under medical advice/supervisions
44
Why is supplementation needed for preterm infants
preterm milk can not supply nutritional needs of premature infants all supplementation products are liquid and sterile *supplementation products are mixed into 60-100ml of human milk and varies by product
45
What infants are therapeutic formulas used for
infants with health conditions requiring dietary adjustments and must be used with medical supervision
46
What are some indications for therapeutic infant formulas
allergy/sensitivity to cow milk or soy protein biliary atresia celiac disease cystic fibrosis various causes of diarrhea gastroesophageal reflux hepatitis lactose intolerance prematurity refractory seizure disorder renal insufficiency
47
What are the number of feedings an infant requires

it can produce severe dehydration within 24 hours this can include fluid and electrolyte imbalances, shock and even death
50
When should you call a medical provider in regards to diarrhea and vomitting
-potential formula-related cause if incorrect dilution of concentrated product or incorrect addition of modular product -severe diarrhea or vomiting -mild symptoms lasting 72 hours -any signs or symptoms associated with dehydration -bloody stool -projectile vomiting -green, bilious vomiting
51
What are the steps that should be taken to prepare equipment for feeding
1. wash hands before handling feeding materials and preparing formula 2. using tongs place all equipment into a deep pan and cover with COLD water 3. bring to a rolling boil and continue boiling for 1-2 minutes 4. Remove equipment from pan using tongs and place on clean towel *Can sterilize in dishwater with a heated drying cycle
52
How do you sterilize tap water
bring to a rolling boil for 1-2 minutes and then allow to cool to room temp for 30 minutes
53
On what part of the body do you test the temperature of the formula before feeding the baby
test on the inside of your wrist
54
How long can you store breast milk for in the fridge and the freezer
store for up to 96 hours in the glass or plastic airtight container in the fridge keep frozen for up to 6 months
55
How do you thaw breast milk
thaw rapidly by holding container under lukewarm water place in lukewarm water bath **use thawed milk within 24 hours or thawing ***NEVER refreeze
56
What are the beyond use dating for each type of formula
1. liquid concentrate can be refrigerated for up to 48 hours 2. ready-to-use formula can be refrigerated for up to 48 hours 3. Unused, reconstituted liquid can be refrigerated for up to 24 hours 4. Unused powder can be stored at room temperature up to 1 month
