Nelson - Routine DR and Initial Care Flashcards
T/F In resource-poor countries, gentle wiping of the face, nose, and mouth with a soft cloth may be equally effective as a bulb syringe
T
Delayed clamping of the umbilical cord (___sec) has value in reducing the incidence of anaemia in infancy
~30sec
T/F Apgar score was designed to predict neurologic outcome
F
T/F Apgar score is normal in most patients in whom cerebral palsy subsequently develops
T
T/F Incidence of CP is low in infants with AS 0-3 @ 5min but higher in infants with AS 7-10
T
T/F Low AS and umbilical artery blood pH predict neonatal death
T
T/F An AS of 0-3 @ 5min is a better predictor of neonatal death than an umbilical artery pH ≤ 7
T
BSA of a newborn is approximately ___ times that of an adult, and heat loss depends on BSA
3
The estimated rate of heat loss in a newborn is approximately ___ times that of an adult
4
Under the usual DR conditions (20-25C) an infant’s skin temp falls approx ___C/min
0.3
Under the usual DR conditions (20-25C) an infant’s deep body temp falls approx ___C/min
0.1
T/F Falsely Low AS: Mg SO4
T
T/F Falsely Low AS: Precipituous delivery
T
Factos that result in falsely negative AS or normal AS
1) Maternal acidosis 2) High fetal catecholamine levels 3) Some full-term infants
T/F Regardless of the etiology, a low AS identifies an infant needing immediate resuscitation
T
Cumulative heat loss immediately after birth
2-3C or ~200kcal/kg
Mechanism of heat loss after birth: To the cooler surrounding air
Convection
Mechanism of heat loss after birth: To the colder materials touching the infant
Conduction
Mechanism of heat loss after birth: To other nearby cooler objects
Heat radiation
Mechanism of heat loss after birth: From skin and lungs
Evaporation
The optimal method of maintaining temp in the stable newborn
Skin-to-skin contact with the mother
T/F Once temp is stabilised, skin and UC of a healthy infant should be cleansed with
Warm water or a mild nonmedicated soap solution and rinsed with water
To reduce colonisation with S. aureus and other pathogenic bacteria, the UC may be treated daily with bactericidal or antimicrobial agents such as
1) Chlorhexidine 2) Triple dye 3) Bacitracin
T/F One application of triple dye followed by 2x daily alcohol swabbing (until the cord falls off) reduces colonisation, exudates, and foul door of the umbilicus in comparison with dry care (soap and water when soiled
T
T/F Topical ointments should not be applied to preterm infants in NICU because this treatment increased risk of bacterial sepsis
T
Routine or repeated total-body exposure to hexachlorophene may be toxic to which body system
Neurologic
Hand-to-elbow washing for ___mins in the initial wash and ___ sec in the subsequent washes is essential for staff and visitors entering the nursery
2, 15-30
T/F The eyes of ALL infants, including those born by CS, must be protected against gonococcal ophthalmia neonatorum by application of a 1-cm ribbon erythromycin (0.5%) or tetracycline (1.0%) sterile ophthalmic ointments in each conjunctival sac.
T
An acceptable alternative to erythromycin and tetracycline eye ointments is ___ but it leads to a transient chemical conjunctivitis in 10-20% of cases
1% silver nitrate
___ should be given to all infants shortly after birth to prevent HDN
IM injection of 0.5-1mg water-soluble vitamin K1 (phytonadione)
T/F Oral Vitamin K is as effective as parenteral dosage in preventing HDN
F
Hepatitis B immunization before discharge from the nursery is recommended for newborns with weight ___kg IRRESPECTIVE of maternal hepatitis status
