What age range will you see the most developmental growth than any other?
The first year.
Infants 1-12 months.
What Erikson theory of development is at the infant stage?
Trust vs Mistrust
Are needs met quickly and consistently?
Development is head to toe and center to the outside, what are the terms explaining this?
Cephalocaudal: head to toe… they learn to lift their head up before arm movement.
Proximodistal: center to periphery… they learn gross motor skills before fine motor skills.
How much weight do babies gain each week in the first 6 months?
5-7 ounces/wk
By what age does the baby’s weight double? Triple?
Double by 6 months, triples by 1 year.
What is the normal growth in length per month for the first 6 months? The second 6 months?
1-6 months = 1 inch/month

When does the anterior fontanel close?
12-18 months.
What is the typical behavior at 2 months?
Head bobs erect temporarily, grasps rattle (briefly) if placed in hand, social smile/coo; regards face, vision is 20/200, responds to loud voices.
Nutritional and anticipatory guidance for 2 months:
Breastfeed or formula (low iron NOT ok), no water/juice.

They are eating well, nice weight gain, no stranger anxiety yet.
What is the normal behavior of a 4 month old?
- Plays with hands
- Reaches for and regards objects
- Mouths objects
- Good head control
- Raises body on hands when prone
- Rolls prone to supine
- laughs
- initiates social contact
Typical nutrition at 4 months:
- Breastfeeding/formula
- may initiate solids (4-6 months, not B4), rice cereal. From denver children’s = start with meats (iron).
Play for 4 month olds:
Talking to baby.
Age appropriate toys, limit swim/bouncy time, should not be only source of entertainment.
Anticipatory guidance for 4 months:
- Car seats
- Falls (rolling and no fear)
- Choking - tp roll tube as guide
- Baby proofing - mobile in next cpl of months.
Growth rate starts to decline at this age:
6 months. Should have doubled weight by now.
Begin oral care w/damp washcloth: teething
- Possible anemia due to iron stores depleted.
Normal behavior for 6 month olds:
No head lag
Rolls supine to prone
Sits with support
Transfers objects
Stranger anxiety begins
Separation anxiety
Imitates
Starts object permanence
6 month nutrition:
Fortified cereal, slowly introduce veggies then fruits.
Introduce new food every 5-7 days.
No bottle in crib (choking, ear infections, dental caries, bonding).
May begin introduction of cup
Limit juice to 2-4 oz / day
New guidelines are to introduce eggs and peanut butter earlier to reduce allergy risk.
NO:
Cows milk
Honey
Citrus
Anticipatory guidance for 6 months:
Poison control center: 800-222-1222
Put dangerous items up high, preferably locked.
Childproofing:
falls - rolling and scooting
burns (they can be “grabby”)
pool/tub
Can use PABA-free sunscreen now.
Anemia is often checked at this month’s check up:
9 months.
Should have teeth by now.
Can begin discipline… set limits, 45 second time-out, but using redirection is best. Might be able to say “no.”
What is the typical behavior of a 9 month old?
Can sit alone
Crawls and creeps
Bears weight on legs when supported
Pincer grasp
Object permanence
Peek a boo
Stranger and separation anxiety
1-2 vocalizations
Nutritional considerations at 9 months:
- 3-4 meals / day, introduce table foods
- Finger foods - chopped, soft: begin self-feed
- Encourage use of cup and weaning from bottle
What do we need to know about sleep at the 9th month?
- Needs decrease (growth slows=req. less sleep)
- 2-3 naps
- May begin bedtime rituals
- May awaken during the night (2ndary to object permanence: remembers caretakers when awake).
Anticipatory guidance for 9 month olds:
- Risk for ingestion - Poison Control Center # available
- Keep dangerous items up high/locked up.
- Childproofing: falls, burns, pool/tub
- NO: honey, citrus, peanuts, popcorn, whole grapes.
We may see cyanosis, pallor, chest deformities, difficult respiratory effort, clubbing, lack of pulses in legs, and visible venous pulsations in children with this condition:
Heart disease.
FTT (failure to thrive) from working to breath, not eating.
May hear murmurs, additional sounds, or thrills
At birth the foramen ovale (between R and L atria) and the ductus arteriosus (between the aorta and pulmonary artery) normally close due to increased pressure int he L atrium>R atrium, the presence of increased O2 concentration in the blood, and decreased prostaglandins.
Always evaluate the PATIENT
not the monitor
For leads:
“White is right, smoke over fire.”
Most common risks of cardiac catheterization:
- Hemorrhage from site
- Loss of pulse in catheterized extremity
- Dysrhythmias
- Thrombus
Pre-op Care
- Diaper rash can cancel procedure if going through femoral
- Allergies? Iodine?
- Asses pedal pulses and make with an “x”
- O2 sats
- Discuss pain control
- Conscious sedation or even general anesthesia
- NPO for 4-8 hours (may need IV [sickle cell])
Post-op Care
Where can they bleed? Throw a clot?
- Watch: bleeding, lack of pulses, arrythmias
- Distal pulses may be weaker at first, color and warmth of limb
- VS, including BP (Q 15 min)
- Dressing free from urine/feces
- If bleeding, apply direct pressure, call provider, reinforce, get help.
- Keep leg STRAIGHT and still 4-8 hours (pre-op teaching should stress this)
- Pain control
- Hydrate, DAT (diet as tolerated)
- Watch blood sugars
This acyanotic heart defect has a hole between the atria (may be at site of foramen ovale):
Atrial Septal Defect (ASD)
Lt to Rt shunt bc pressure is greater on Lt.
Oxygenated blood from Lt atria shunts into Rt to be recycled again through pulmonary system, thus increased pulmonary flow w/no cyanosis.
Rt side enlarges bc increased flow
S and S of ASD:
Asymptomatic to CHF (unusual)
Murmur
Risk for emboli later if not repaired.
Treatment for ASD:
Surgical repair with patch, open heart or cath.
Lifelong monitoring for arrhythmias.
This acyanotic heart defect is from a hole between ventricles:
Ventricular Septal Defect (VSD)
Lt to Rt shunt due to greater pressure of Lt side, oxygenated blood from Lt recycled through pulmonary system (like ASD), Rt side enlargement like ASD.
This condition is often associated with other defects.
S and S of VSD:
- CHF common (many congenital defects have CHF as a complication)
- Murmur
Treatment of VSD:
- 20-60% may close spontaneously. The time they wait to see if this happens depends on their threat to life.
- Surgical repair with patch or sutures, open or cath.
This heart defect is due to the failure of the fetal ductus to close after birth:
Patent Ductus Arteriosus (PDA).
[In utero it’s held open by low O2 and prostaglandins from the placenta. At birth, the O2 goes up (lung use), prostaglandins decline and hole closes.]
In PDA blood shunts from aorta (higher pressure) to pulmonary artery, recycling through lungs.
- Lt side hypertrophy possibly Rt-sided as well.
S and S of PDA:
Treatment?
- Murmur
- CHF common
Tx:
Medical management with indomethacin.
Indomethacin is a prostaglandin inhibitor. Works 75% of the time.
Surgical repair is open heart or cath.
Patent Ductus Arteriosus
What is the normal range of an infant’s heart rate?
130-140 bpm
What is the Moro reflex and what does it indicate?
Whole body response to noise…
Indication of healthy, intact nervous system.
Meaning of ecchymotic?
An ecchymosis is a subcutaneous spot of bleeding (from extravasation of blood) with diameter larger than 1-centimetre (0.39 in). It is similar to (and sometimes indistinguishable from) a hematoma, commonly called a bruise, though the terms are not interchangeable in careful usage.[1] Specifically, bruises are caused by trauma whereas ecchymoses, which are the same as the spots of purpura except larger, are not necessarily caused by trauma,[2] often being caused by pathophysiologic cell function.
How can you tell the difference between scalp edema (acaput succedaneum) and a cephalhematoma?
With caput succedaneum the swelling crosses a suture line .
What are the five areas tested for the Apgar?
Heart rate, respiratory effort, muscle tone, reflex irritability, and color.
What can lead to hypoglycemia in a newborn?
Being born from a diabetic mother, The pancreas of a fetus of a diabetic mother responds to the mother’s hyperglycemia by secreting large amounts of insulin; this leads to hypoglycemia after birth.
Why are babies born to diabetic mothers larger?
The mothers extra glucose stimulates the baby to store extra tissue and fat in response. It is important that the mother keeps up with her exogenous insulin.
A fetal scalp pH of less than 7.2 indicates what?
Fetal hypoxia, emergency situation.
