Q

Apgar Score

A

This score is indicative of the need for resuscitation, NOT the degree of asphyxia in a newborn

Each factor is scored 0, 1, or 2 and a lower number indicates need for resuscitation

Q

How is part of the lung fluid pushed out of the infant?

Q

How does a drop in prostaglandins contribute to respiration in the newborn?

Q

Q

What should you do if you get a newborn temp of 97.6 F or lower?

A

Q

Non-shivering Thermogenesis

Shivering that occurs when skin receptors perceive a drop in environmental temperature

The newborn will shiver and double the metabolic rate and increase muscle activity

All of this is done to generate heat

114
Q

How do meconium stool, breast milk stool, and cows milk stool compare?

A

Meconium - extremely dark green or black and it is sticky and adheres to the baby so we need to assure we get it all off

etc…

day 6+ its about 6-8 wet diapers a day

118
Q

What is the immune system like for the fetus and newborn?

A

The immune system is not fully activated until after birth, so the newborn has poor hypothalamic response to pyrogens

119
Q

___ is not a reliable indicator of infection - in the newborn period, ___ is a more reliable indicator of infections

A

fever; hypothermia

120
Q

You rarely see a temperature elevation until a week or two after birth because…

A

there is no pyrogen reaction from hypothalamic response

121
Q

Passive Newborn Immunity

A

Lasts 4 weeks

Passive immunity occurs and is gained during the third trimester and through antibodies in the mothers breast milk

122
Q

Why are preterm infants more susceptible to infection?

A

Antibodies move from the mom to fetus in the last 4 weeks of pregnancy - this is why premes are at higher risk for infection since they lost some of that time or all of it

123

Circumference

Fontanelles

Overriding Sutures

Checks for issues like cephalo hematoma, subgaleal hemorrhage, and caput succedaneum

134
Q

Fontanelles

A

Openings in the skull where the sutures have not closed yet (normal finding) and is the “soft spot”

There is an anterior and posterior one

135
Q

Anterior Fontanelle

A

Diamond shaped opening toward the front of the dorsal side of the skull

136
Q

Posterior Fontanelle

A

Triangle shaped opening toward the back of the skull but it CAN be closed at delivery so you may be unable to palpate

137
Q

Overriding Sutures

A

Craniosyntosis where the skull plates close/overlap and cause pressure for the ever growing brain

The fetal skull is a series of plates that can slip one over and under the other to allow the skull to compress and elongate to get through to pelvis usually

138
Q

Molding

A

Coning of the head that occurs in the head of the newborn at delivery

139
Q

Cephalo/a Hematoma

A

Area of bleeding into the scalp following delivery related to trauma of the scalp

Has more distinct edges than caput succedaneum

140
Q

Subgaleal Hemorrhage

A

Bleeding between the scalp and skull that often occurs from the use of a vacuum extractor (hematoma)

This occurs on a more superficial layer than an epidural hematoma which is below the skull bones while subgaleal is above

distinct edges are here but it is much larger than a cephalo/a hematoma

141
Q

Caput Succedaneum

A

swelling of the scalp itself

tends to cross the suture line (right to left side)

Less defined edges

142
Q

How does Caput and Succedaneum differ from Hematomas in the newborn?

A

Caput Succadaneum - will cross suture lines (go over fontanelle regions)

Hematomas will not cross suture lines since the vessels do not cross over

143
Q

What skin colors could be seen in newborns?

A

Pink

Jaundice

Pallor

Cyanosis

144
Q

Pink Skin Tone

A

normal skin tone in the majority of the average newborn body

145
Q

A

Common AFTER 24 hours, but BEFORE 24 hours is abnormal

146

155
Q

Q

Glabellar Reflex and Habituation

A

Eyes blink upon touching the bridge of the nose but they will habituate to the stimuli over time

162
Q

What is the benefit of habituation in the newborn?

A

It allows the newborn to notice and interpret stimuli, and to tune out things that they do not need to be neurologically bombarded by (that’s why maybe a loud house has a baby that grows used to it while a quiet house has an easily disturbed baby)

163
Q

What may constant and frequent sneezing be indicative of in an infant?

A

While sneezing is normal, this constant and frequent amount may be indicative of withdrawal

It rules out newborn cataracts

176
Q

178
Q

What is interesting about the clear eye discharge of a newborn?

  2. If there is gonorrhea or chlamydia issues then an ointment can be applied
  3. A lot of this discharge is r/t eye prophylaxis
179
Q

Scleral Hemorrhage

A

A common finding in the newborn from the vaginal squeeze

184
Q

Why do we check newborn ear recoil?

A

It is an assessment for gestational age

If it is adequate, there should be recoil if the pinna comes forward because of adequate cartilage formation

185
Q

How should hearing be immediately after birth for the newborn?

A

It should be present, but in the first 24 hours there is often amniotic fluid, cells, vernix that can initially diminish sounds

We do a hearing exam after 24 hours because of this

Should still be able to react to noise

2

231
Q

The First Period of Reactivity

A

About 30 min to an hour (maybe longer), occurs right after birth of baby

Newborn is awake and active

Appears hungry (best time to breastfeed) and has a strong reflex

Natural opportunity to start breastfeeding

Vital signs are elevated at this time

232
Q

The Second Period of Reactivity

A

Period of reactivity lasting 4-6 hours in a normal newborn

The baby “crashes and burns” making breast feeding hard as they are now overwhelmed with new stimuli

1st Period –> 4-6 hours of deep sleep –> 2nd Period where baby is acutely alert, first meconium passes and another great period to begin breast feeding will begin

Newborn will suck root and swallow in this period, pass meconium, and the heart and respiratory rates increase, so the nurse will be alert for apneic periods

Tend to stay in a flexed position and will resist straightening

Hands will remain clenched

234

A

Hearing

Metabolic Screening (43 tests in NYS)

Transdermal Bilirubin/Serum Bilirubin (check for abnormal jaundice)
