Q

define postmenstrual age

A

postmenstrual age- age from 1st day of the last menstrual period
gestational age, chronological and corrected ages are more frequently used

2
Q

define chronological age

A

chronological age- actual age of the born baby

3
Q

define corrected age

A

Corrected age, or adjusted age, is your premature baby’s chronological age minus the number of weeks or months he was born early. e.g. baby born 10 weeks early and now he is 3 month-> 12 completed weeks since being born; out of 12 weeks: 10 weeks of pregnancy and 2 weeks of his age that he would have been born

4
Q

define gestational age

A

gestational age- from 1st day of last menstrual period till the day of birth; used for a period of pregnancy till birth; used to describe the age of premature infant e.g. a child born 10 weeks early-> gestational age of 30 weeks (30 out of 40)

5
Q

list gestational, chronological, corrected and postmenstrual age of a bb that is 10 weeks premature and u see him 3 month after being born

A

baby has 42 weeks postmenstrual, 42 weeks gestational age, 2 weeks corrected age and 12 weeks chronological age

6
Q

how old should an infant be to be considered viable?

A

22 weeks

7
Q

until what age is GA age used for preterm bbs? why

A

usually corrected Ga age is used until baby is 2 years-> this is more reflective of possible issues

8
Q

definitions of different stages of pre-term and pos-term infants

A
  • Preterm:GA<37 weeks at birth
  • Extremely preterm: GA<28 weeks at birth
  • Very preterm:28-31 6/7 weeks at birth
  • Moderately preterm: 32-33 6/7 weeks at birth
  • Late preterm: 34-36 6/7 weeks at birth
  • Term: GA>37 weeks
  • Postterm: 42 to 46 weeks after birth
9
Q

10
Q

what is IUGR?

A

Intrauterine growth restriction

• Failure of the fetus to achieve normal predicted growth in utero

11
Q

what are the causes of IUGR?

A

probably had compromised nutrition while in utero
usually happens early-
before 2 weeks

12
Q

types and causes of IUGR

A

Symmetric IUGR: 20-30% of all cases of IUGR
• Weight, length and head circumference less than 10th %ile.
- Indicative of chronic malnutrition
common causes:
- genetic disorder-> smaller potential of growth
may be due infections during
pregnancy
- early onset

Asymmetric IUGR
• Length and head circumference are appropriate but weight is below the 10th %ile. Better head sparing Indicative of an acute insult in nutrition usually in 3rd trimester
characteristic of acute insult- not enough nutrition or oxygen due to placental insufficiency (preeclampsia)

13
Q

which score is used to assess health at birth?

A

Apgar

14
Q

describe APGAR score

A

Appearance, Pulse, Grimace
Activity, Respiration

  • Neonatal health assessment
  • Scored out of 10 at 1 min, 5mins and 10 mins
  • Provide information on delivery event
  • Risk of perinatal depression
15
Q

when is mid-upper arm assessment is used?

A

Mid-upper arm: more in community and research setting, reflects malnutrition

16
Q

when is upper arm and lower limb assessment used?

A

handicap kids

17

who is used for term infants

19
Q

what are the types of WHO growth curves for brith-24 months babies

A
  1. length for age and weight for age

2. head circumference and weight for length

20
Q

which ages are covered by WHO curves?

A
  1. birth-> 24 months

2. 24 month-> 19 yo

21
Q

what are the types of WHO growth curves for 24 months-> 19yo

A
  1. height for age and weight for age

2. BMI for age

22
Q

is weight or BMI a preferred method of assessment in curves for teens? Why

A

BMI

teens go through growth spurts at different points-> different weight at the same age

23
Q

Specialized growth charts are available for the following conditions:

A
  • Prader-Willi syndrome
  • Cornelia deLange syndrome
  • Turner syndrome
  • Trisomy 21 (Down’s syndrome)
  • Rubinstein-Taybi syndrome
  • Marfan syndrome
  • Achondroplasia
24
Q

Interpreting growth chart

When to be worried?

A

Plateauing: bb is not growing over time-> sign of chronic malnutrition
Falling off 50th %ile: bb is growing over time, but not fast enough-> sign of chronic malnutrition
Sharp decline: losing weight-> acute malnutrition e.g. trauma
Incline in BMI: child is gaining too much weight

25
Q

Common Anthropometric Criteria for Diagnosing Failure to Thrive

A

Body mass index for age less than the 5th percentile
Length for age less than the 5th percentile
Weight deceleration crossing two major percentile lines (most common definition)
Weight for age less than the 5th percentile
Weight less than 75 percent of median weight for age
Weight less than 75 percent of median weight for length
Weight velocity less than the 5th percentile

26
Q

more severe cases of failure to thrive is when

A

more severe cases of failure to thrive is when length and head circumference is also being affected, not just weight

27
Q

Interpreting linear growth chart

congenital growth hormone deficiency

A

no need for nutritional intervention, but there is a need for hormone supplementation when hormones are supplemented, the growth will return to normal
the weight does not fall in the way that height does

28
Q

Interpreting linear growth chart

Constitutional delay of growth and adolescence

A

curve starts to fall from 3rd percentile typically: small at first then rapid growth
no need to intervene

29
Q

Interpreting linear growth chart

familial or genetic short stature:

A

short genetic potential, nothing u can do weight and height follow the same pattern

30
Q

Interpreting linear growth chart

primary nutritional deficiency and severe illness:

A

weight starts to fall below 3rd percentile linear growth curve occurs in delay, later than weight
this signals for chronic malnutrition -> need for intervention

31
Q

What is the first and the last thing to be affected in case of malnutrition on linear growth charts?

A

head crmc is the last thing to be affected in case of malnutrition
weight is the first things affected, the next is linear growth

32
Q

how are weight and height affected when nutritional support is administered

A

weight will improve first, followed by the height

33
Q

stunting- changes after administering nutritional support

A

may take years for height to improve

34
Q

what are good markers of chronic malnutrition

A

height and head circumference

35
Q

what are good markers of acute malnutrition

A

weight

36
Q

__ is the adaptive response to suboptimal nutrition

A

Growth deceleration is the adaptive response to suboptimal nutrition

37
Q

Interpreting linear growth in Stunting or Nutritional Dwarfism:

A

• -2 SD below the height for age curves; not necessarily associated with emaciation; short stature or poor growth may be the sole manifestations of nutritional inadequacy

38
Q

Interpreting linear growth” Short stature

need for nutr intervention?

A
no nutritional intervention
• Familial/genetic
• Growth is parallel to the normal centile usually below the 5th %ile
• Final adult stature is short
- no need for nutritional intervention
39
Q

to decide genetic vs nutritional cause of short stature :

A

1) check literature for child’s condition and expected growth
2) calculate mid parental height

40
Q

What is post-natal fluid adaptation

A

In the wob, baby was surrounded by fluid-> now it is in the environment with no fluid

changes occur:
• Efflux of fluid ICF to ECF
• Excess ECF floods neonatal kidneys

41
Q

Phases during the 1st week of life

dietary intake
urine output
weight

A
Prediuretic phase 
Age: birth - 2 days
dietary intake: few drops
urine output: low proper milk let-down
weight: wt loss due to water loss via skin 
Diuretic phase 
Age: 1-5 days
dietary intake: low
urine output: abrupt increase as kidneys start working more
weight: wt loss
Homeostatic  phase 
Age: after 2-5 days
dietary intake: increase
urine output: decreases, then proportional to intake
weight: start to regain
42
Q

is weight loss normal in newborns?

A

weight loss after birth is normal for both term and preterm

43
Q

First week of live: term vs preterm in terms of acceptable weight loss, regain time and z core

A

Preterm
15% weight loss is acceptable
Regain by 10-14days
loose Not more than -0.8 Z score. If lost more than that-> failure to thrive

Term
7-10% wt loss is acceptable
Regain by 7-10 days

44
Q

when is nutr intervention appropriate in terms of weight regain by bbs

A

if baby hasn’t started to regain weight by day 5

45
Q

First week of life: Who are the babies at risk?

A

these babies are at risk of not being able to regain their birth weight-> have to be monitored more closely

  • C section mothers

Q

Number of diapers as baby grows

A

for the first 6 days, baby should have as many diapers as days old
diaper should get heavier with urine each day, especially after day 3, as the supply of milk increases

57
Q

Breastfeeding assessment questionnaire

A
