• Infant should be weighed NUDE (diaper off) and in a lying position
-We need to measure exactly to the OUNCE
What is typically included in an infant well child visit?
o Height, weight, head circumference and plotting o Vital signs o Developmental screening o Nutritional assessment o Physical examination o Anticipatory guidance o Immunizations
How to obtain head circumference for an infant?
- Measure the head at its greatest circumference (usually slightly above the eyebrows and pinna of the ears and around the occipital prominence at the back of the skull)
- Repeat measurement for accuracy

How to take heart rate in an infant?
- Apically
- Heard through the stethoscope held to the chest at the apex of the heart (4th intercostal space midclavicular); count the pulse for 1 full minute because of irregularities
Normal heart rate in an infant
80-150 (up to 200 with excitement/fever)
normal respiratory rate in an infant
24-50
How to measure RR in an infant?

what is the most widely used developmental screening tool?
The Denver II test
What is the Denver II test?
4 areas of focus are: Gross Motor, Language, Fine Motor and Personal-Social. (from birth to 6 yrs)
• The examiner should be trained by a master instructor
• In general: Mostly used to screen for developmental delays
• Child is expected to perform every item to the left of the line and items that intersect the line that are in the 75-90th % (shaded box)
• The best source of info about child is the PARENT(S)
what happens to BP, HR, and RR as kids get older?
BP: increases
RR: decreases
HR: decreases
developmental milestones for a 1 month old?
• 1 month: can turn head from side to side, grasp reflex is strong, follows to midline, makes comfort sounds during feeding
developmental milestones for a 2 month old?
• 2 months: when prone can lift head to 45 degrees, hands often open, when supine follows to beyond midline, gurgles, holds placed rattle, smiles spontaneously
developmental milestones for a 4 month old?
• 4 months: raises head and chest with arm support, sits head steady, inspects and plays with hand, reaches and grasps rattle, makes consonant sounds “b” , watches hand, calms when spoken to/picked up/sucking/or looking, self-soothes to sleep
developmental milestones for a 6 month old?
• 6 months: primitive refelxes GONE! no head lag, pulls to sit and sits tripod, holds bottle, reaches and shakes rattle, passes cube, looks for yarn, will turn head to side when hears voice, imitates sounds, babbles, LAUGHS, shows interest in other infants, **foot to mouth when supine
developmental milestones for a 9 month old?
• 9 months: postural reflexes present, ROLLS BOTH WAYS, sits well- no support, raking pincer grasp (touches cheerio w/ finger), bangs two cubes together, understands no, may say “Mama”, “Dada”, waves bye bye
