Maternity N144 Test 1 Questions With
Correct Answers
Goals for Respiratory Transitions - CORRECT ANSWER✔✔-Respirations
|| || || || || ||
begin and continue effectively
|| || || || ||
Fluid is cleared from airways; transition made from fluid to gas
|| || || || || || || || || ||
Fetal lung development - CORRECT ANSWER✔✔-Surfactant
|| || || || || ||
(phospholipid) ||
begins 28 weeks, peaks at 35 weeks
|| || || || || ||
Maintains alveolar stability || ||
Secreted in the lining of the alveoli onto the alveolar surface
|| || || || || || || || || || ||
Enables the establishment of functional residual capacity
|| || || || || ||
***************
Instill surfactant into lungs when they are born when they do not
|| || || || || || || || || || || ||
have enough. Amnio tells us how much surfactant.we have.
|| || || || || || || ||
Not really breathing in utero- "practicing"
|| || || || ||
Fetal breathing movements - CORRECT ANSWER✔✔-Essential for
|| || || || || || ||
developing chest wall muscles and the diaphragm
|| || || || || ||
,What Factors Influence Respirations? - CORRECT ANSWER✔✔-
|| || || || || ||
Mechanical
Fetal chest compression and recoil
|| || || ||
Chemical ||
Chemoreceptor stimulation || ||
Decreased PO2 and Increased PCO2
|| || || || ||
Thermal ||
Sudden cooling stimulates sensory receptors
|| || || || ||
Sensory
Handling and drying; tactile stimulation
|| || || || ||
Hormonal ||
Increased norepinephrine & epinephrine stimulate cardiac output,
|| || || || || || ||
surfactant release and promotion of pulmonary fluid clearance
|| || || || || || ||
Expected Findings for Respirations - CORRECT ANSWER✔✔-Nose
|| || || || || || ||
breathers ||
Respirations are shallow and irregular || || || || ||
Chest and abdomen rise simultaneously
|| || || || ||
Short periods of apnea (< 15 seconds)
|| || || || || || ||
Expected respiratory rate 30-60/min
|| || ||
Airway noises may be present
|| || || || ||
, Breathe out of nose because they are breastfeeders; flat wide
|| || || || || || || || || ||
noses.short periods of apnea less than 15 seconds! Listen to baby
|| || || || || || || || || || ||
for a full minute.
|| || ||
Crackles because their lungs are filled with fluid- normal
|| || || || || || || ||
Signs of Respiratory Distress - CORRECT ANSWER✔✔-Persistent nasal
|| || || || || || ||
flaring
|| ||
Retractions ||
Expiratory grunting || ||
Increased use of intercostal muscles
|| || || || ||
Tachypnea > 60 breaths per minute || || || || ||
Cyanosis
Circulatory Transition - CORRECT ANSWER✔✔-Systemic vascular
|| || || || || ||
resistance must increase || || ||
Blood must circulate through the lungs
|| || || || ||
Dilation of the pulmonary artery
|| || || || ||
Pulmonary vascular resistance must decrease
|| || || ||
Fetal shunts must close
|| || || ||
Dependent on a decrease in PVR || || || || ||
