Exam 3 review Flashcards
(207 cards)
What are the four types of heat loss?
- Radiation
- Conduction
- Convection
- Evaporation
What is radiation heat loss?
Heat loss due to heat transfer to cooler surfaces and objects not directly in contact with the body. Think heat lamp
What is conduction heat loss?
Loss of heat to a cooler surface directly from skin contact.
Baby on moms chest warms; baby on cold table or bed
What is convection heat loss?
Loss of heat from the warm body to the air (think wind/ac)
What is evaporation heat loss?
Loss of heat when water on the skin is converted to a vapor.
Think wet baby
What are the 3 physiologic adaptations of fetal circulation?
- Foramen ovale
- Ductus arteriosus
- Ductus venosus
What is the #1 nursing priority in regards to the infant immediately after birth?
WARM, dry, stimulate; suction airway
A premature infant is classified as an infant born before ___ weeks.
37 weeks
How is circulation assessed in a newborn?
pulse ox/palpate femoral artery
where is the pulse ox placed?
Right upper extremity; palm of hand
What is a complication of supplying oxygen to premature infants?
retinopathy and prematurity of lungs
The umbilical vein carries ______ blood to the baby in utero.
Oxygenated
The umbilical arteries carry _____ blood to the placenta in utero.
Deoxygenated
SGA (small for gestational age) is
An infant that is less than 10% of the birth weight.
Maternal risk factors for SGA (8)
- malnutrition
- HTN
- smoking
- substance abuse
- DM
- cardiac/renal abnormalities
- young maternal age
- hx of small babies
SGA infant complications (4)
- Congenital aspiration syndrome (meconium)
- Hypoxia
- Hypoglycemia
- Polycythemia (too many RBCs increased rx for clots)
LGA (Large for gestational age) is
A baby born above 90th percentile
Maternal Rx factors for LGA (3)
- DM
- Obesity
- hx of big babies
LGA infant complications (6)
- birth trauma from vag: clavicle fracture depressed skull fracture cephalohematoma - fetal distress - hypoglycemia - hypocalcemia - prolonged labor - hyperbillirubemia
IUGR (intrauterine growth restriction) is
Advanced gestation with limited fetal growth.
Maternal Rx factors for IUGR (7)
- multiples
- smoking
- old
- poor nutrition
- substance abuse
- poor prenatal care
- HTN
IUGR infant complications (8)
- meconium aspiration
- hypoxia
- hypoglycemia
- increased rx for infection
- cerebral palsy
- still born
- poor temp control
- motor/neuro disabilities
Contraindications for breastfeeding (4)
- HIV/aids
- illicit drug/alcohol use
- TB
- Galactosemia
How does an infant receive IgG (given)
Passive immunity; passed through fetus via placenta; received last four weeks of pregnancy; premes dont get this and are at increased rx of infection
