NUR 230 Exam 1
What is the first breath of life characterized by? ---------CORRECT
ANSWER-----------------A gasp that generates an increase in
transpulmonary pressure and results in diaphragmatic descent.
What role does surfactant play in newborn lungs? ---------CORRECT
ANSWER-----------------Surfactant reduces surface tension, preventing
alveolar collapse and loss of lung volume.
How does the amount of surfactant relate to the risk of respiratory
distress in premature infants? ---------CORRECT ANSWER-----------------
More premature infants have less surfactant, increasing the risk of
respiratory distress.
,What happens to the fluid in the lungs during birth? ---------CORRECT
ANSWER-----------------Fluid is removed and replaced with air; passage
through the birth canal helps eliminate two-thirds of the fluid.
What is the normal respiratory rate for newborns? ---------CORRECT
ANSWER-----------------30-60 breaths per minute, with short periods of
apnea lasting less than 5-10 seconds.
What are signs of respiratory distress in newborns? ---------CORRECT
ANSWER-----------------Central cyanosis, tachypnea, expiratory grunting,
sternal retracting, and nasal flaring.
What is the significance of clamping the umbilical cord after birth? ------
---CORRECT ANSWER-----------------It eliminates the placenta as a
reservoir for blood, initiating cardiovascular changes.
What causes the closure of the foramen ovale in newborns? ---------
CORRECT ANSWER-----------------Increased pulmonary blood flow and
pressure in the left atrium after the onset of respirations.
,What happens to the ductus arteriosus after birth? ---------CORRECT
ANSWER-----------------It closes within 10 to 15 hours after birth due to
increased pressure in the aorta.
What is a neutral thermal environment (NTE) for newborns? ---------
CORRECT ANSWER-----------------An environment where body
temperature is maintained without increased metabolic rate or oxygen
use.
What is cold stress in newborns? ---------CORRECT ANSWER-----------------
Excessive heat loss requiring compensation through non-shivering
thermogenesis, which can lead to various health issues.
What are some characteristics that predispose newborns to heat loss? -
--------CORRECT ANSWER-----------------Thin skin, increased skin
permeability, lack of shivering ability, limited metabolic substrate
stores, and large surface area-to-body mass ratio.
What is bilirubin and why do newborns have high levels? ---------
CORRECT ANSWER-----------------Bilirubin is a byproduct of RBC
breakdown; newborns have higher levels due to a higher turnover of
RBCs.
, What is jaundice in newborns? ---------CORRECT ANSWER-----------------A
condition characterized by yellowing of the skin, sclera, and mucous
membranes, typically mild and self-limiting.
What is the treatment for severe jaundice in newborns? ---------
CORRECT ANSWER-----------------Phototherapy, which involves exposing
the baby to UV light to break down bilirubin.
What is meconium? ---------CORRECT ANSWER-----------------The first
stool of a newborn, composed of amniotic fluid, shed mucosal cells, and
intestinal secretions.
What does transitional stool look like in newborns? ---------CORRECT
ANSWER-----------------It has a yellow mustard seedy appearance and
varies based on whether the baby is breast-fed or formula-fed.
How does early feeding affect bilirubin levels in newborns? ---------
CORRECT ANSWER-----------------Babies fed sooner after birth will have
lower levels of bilirubin more quickly.
