RNC-NIC Questions with correct answers
Complications of hyperthermia Correct Answer--increased metabolic
demands
-increased oxygen requirements
-apnea
Why might a HYPERthermic infant be hypotensive? Correct Answer-
They are vasodilated in an attempt to dissipate heat
What are three complications of increased insensible water loss? Correct
Answer-HYPERnatremia, dehydration, evaporative heat loss
What circumstances would warrant a baby being on an elemental
formula? Correct Answer-Liver disease, short gut syndrome, dysmotility
(such as gastroschisis), malabsorption, severe protein allergies
Most common causes of metabolic acidosis in NICU population Correct
Answer-Renal tubular acidosis/renal failure, lactic acidosis (tissue
hypoxia, sepsis, neonatal cold stress)
Common causes of metabolic alkalosis Correct Answer-Vomiting,
NG/OG suctioning, sodium bicarb use
How is PIP adjusted in accordance with PaCO2? Correct Answer-
Elevated PaCO2 -> Increase PIP
Low PaCO2 --> Decrease PIP
,What is the general indication for HFOV? Correct Answer-Conventional
ventilator failure
When does FUNCTIONAL closure of the ductus arteriosus occur?
Correct Answer-within the first 12hrs after birth
When does the ANATOMIC closure of the ductus arteriosus occur?
Correct Answer-Can take up to one month after birth
TTN (Transient tachypnea of the newborn) Correct Answer--Respiratory
distress caused by ineffective breathing at birth; delayed clearance of
lung fluid
-Tachypnea, grunting, shallow breathing, nasal flaring, respiratory
acidosis
-May need intubation and ventilation
-Sunburst pattern with perihilar streakiness on x-ray
-Fluid in interlobar tissue
Normal Urine output Correct Answer-1-4 ml/kg/hr
What are three effects of perinatal steroids on neonates? Correct
Answer--Maturation of epithelial skin barrier and renal epithelial
transport system
-Lower incidence of insensible water loss & hypernatremia
,-Lower fluid requirements in first 7 days of life
What mineral aids in bone mineralization? Correct Answer-Phosphorus
Chloride Correct Answer-Normal value 96-111
Inverse correlation with bicarb
too much = acidosis
too little = alkalosis
Potassium Correct Answer-Normal value 3.5-5.5
If abnormal, can cause weakness, arrhythmias, even death
Sodium Correct Answer-Normal 135-145
If abnormal, can cause seizures, venous sinus thrombosis, CNS
hemorrhage
What are some complications of cold stress? Correct Answer-Apnea,
low blood sugar, low blood pressure, seizures
Radiant heat loss (Radiation) Correct Answer--Transfer of heat between
two objects that do not touch each other
#1 mode of heat loss for preemies in after first week of life
-Ex - baby's bed is near a cold, closed window
, Evaporative heat loss Correct Answer-Transfer of heat through water
loss
#1 mode of heat loss in preemies in first week of life
ex - baby on wet blankets
Convection heat loss Correct Answer-Transfer of heat to colder air in
environment
ex- infant in drafty area or cold room
Conductive heat loss Correct Answer-Transfer of heat from a warm
surface to a cold surface
ex- baby placed on cold scale
Cryptorchidism Correct Answer-undescended testes
First Pass Effect Correct Answer-Hepatic bio-transformation may
markedly alter drug availability by directly metabolizing drugs absorbed
from the GI tract before those drugs reach systemic circulation
How is PPHN diagnosed? (gold standard) Correct Answer-
Echocardiogram shows right to left shunting
PROM Correct Answer-Premature rupture of membranes (before onset
of labor)
risk of cord prolapse
