The immediate first breath of a newborn primarily triggers which physiological change?
- A Closure of the ductus venosus
- B Increase in systemic vascular resistance
- C Decrease in pulmonary vascular resistance
- D Activation of fetal hemoglobin production
Correct answer: Decrease in pulmonary vascular resistance
When the newborn takes the first breath, lung aeration causes pulmonary vessels to dilate and pulmonary vascular resistance (PVR) falls markedly.
Why is delayed cord clamping often beneficial in a term newborn?
- A It maintains higher pulmonary vascular resistance
- B It slows the transition from fetal to neonatal circulation
- C It adds placental blood volume to the infant
- D It ensures faster closure of the ductus arteriosus
Correct answer: It adds placental blood volume to the infant
Delayed cord clamping allows placental transfusion, increasing neonatal blood volume and improving hemodynamic stability during the transition to neonatal circulation.
Which factor plays a major role in the clearance of fetal lung fluid at birth?
- A Low cortisol levels
- B High pulmonary vascular resistance
- C Sodium-driven reabsorption of lung fluid
- D Persistence of fetal hemoglobin
Correct answer: Sodium-driven reabsorption of lung fluid
After birth, active absorption of lung fluid (via sodium channels) and lung aeration help clear fetal lung fluid, allowing gas exchange to begin.
A newborn who is term is found to have a heart rate of 90 beats/min at 1 minute of life. According to standard neonatal assessment, this is considered:
- A Persistently low circulating cortisol levels
- B High pulmonary vascular resistance
- C Sodium-driven reabsorption of lung fluid
- D Persistence of fetal hemoglobin in blood
Correct answer: Sodium-driven reabsorption of lung fluid
A term newborn should have heart rate >100 bpm by the first minute; heart rate <100 bpm suggests possible inadequate transition, requiring prompt stimulation or resuscitation per neonatal guidelines.
What is the primary mechanism leading to the functional closure of the ductus arteriosus in a healthy term neonate?
- A A normal finding needing no action
- B Bradycardia needing stimulation or resuscitation
- C Tachycardia requiring active cooling
- D A clear sign of hyperthermia
Correct answer: Bradycardia needing stimulation or resuscitation
After birth, increased oxygen and decreased prostaglandins lead to vasoconstriction of the ductus arteriosus and eventual closure (functional closure) of that fetal shunt.
Which of the following assessments should be performed first in the routine newborn examination within minutes after birth?
- A Measuring the newborn's head circumference
- B Checking vital signs (heart rate, breathing, temperature)
- C Performing a heel-stick glucose measurement
- D Giving the newborn a first bath
Correct answer: Checking vital signs (heart rate, breathing, temperature)
Immediately after birth, vital signs (heart rate, respiratory rate, temperature) are critical to assess early physiological adaptation and to identify any need for immediate intervention.
Which statement about thermoregulation in the newborn is correct?
- A Newborns generate heat efficiently by shivering
- B Brown fat metabolism and vasoconstriction drive heat production
- C Newborns do not lose any heat through evaporation
- D Hypothermia is not a concern for term newborns
Correct answer: Brown fat metabolism and vasoconstriction drive heat production
Newborns primarily use non-shivering thermogenesis (via brown fat) and peripheral vasoconstriction to maintain body temperature; shivering is not effective.
During newborn assessment, what does apneic spells for 12 seconds between respiratory efforts at 6 hours of life indicate?
- A Normal periodic breathing
- B Pathologic apnea requiring immediate intervention
- C Indicates surfactant deficiency
- D Sign of congenital heart disease
Correct answer: Normal periodic breathing
Short periodic breathing (brief pauses) is common in healthy newborns as they adjust; true pathologic apnea is longer pauses or associated with bradycardia or cyanosis.
In a newborn with delayed transition, what is a likely contributing factor?
- A Onset of strong labor contractions before delivery
- B Surge in fetal catecholamines during the birth process
- C Retained fetal lung fluid from cesarean birth without labor
- D Excessive surfactant production by the fetal lungs
Correct answer: Retained fetal lung fluid from cesarean birth without labor
Delayed transition and respiratory difficulties may result from retained fetal lung fluid, especially in infants born by cesarean section without labor.
What physiological change is primarily triggered by the immediate first breath of a newborn?
- A Closure of the ductus venosus
- B Increase in systemic vascular resistance
- C Decrease in pulmonary vascular resistance
- D Activation of fetal hemoglobin production
Correct answer: Decrease in pulmonary vascular resistance
When the newborn takes the first breath, lung aeration causes pulmonary vessels to dilate and pulmonary vascular resistance (PVR) falls markedly.
Which structure normally begins to close as left atrial pressure exceeds right atrial pressure after birth?
- A Ductus arteriosus
- B Foramen ovale
- C Ductus venosus
- D Umbilical vein
Correct answer: Foramen ovale
The foramen ovale flap closes when left atrial pressure increases (from increased pulmonary venous return) and right atrial pressure falls, shutting the right-to-left atrial shunt.
What is the significance of a heart rate of 90 beats/min in a term newborn at 1 minute of life?
- A A normal heart rate for a term newborn
- B Bradycardia needing stimulation or resuscitation
- C Tachycardia requiring active cooling measures
- D An expected sign of neonatal hyperthermia
Correct answer: Bradycardia needing stimulation or resuscitation
A heart rate <100 bpm in a term newborn suggests possible inadequate transition, requiring prompt stimulation or resuscitation per neonatal guidelines.
What metabolic change occurs in a newborn immediately after birth?
- A A sharp decrease in circulating catecholamine levels
- B A rapid increase in glucose supplied by the placenta
- C A marked increase in systemic vascular resistance
- D A catecholamine and glucagon surge sustaining glucose and pressure
Correct answer: A catecholamine and glucagon surge sustaining glucose and pressure
Separation from the placenta removes maternal glucose supply, leading to a catecholamine and glucagon surge to support various physiological processes.
How does skin-to-skin contact immediately after birth primarily benefit a newborn?
- A Faster closure of the ductus arteriosus shunt
- B Increased retention of fetal lung fluid
- C Thermoregulation and respiratory adaptation support
- D Delayed onset of spontaneous breathing
Correct answer: Thermoregulation and respiratory adaptation support
Skin-to-skin contact promotes thermoregulation, reduces heat loss, and supports the metabolic and respiratory transition of the newborn.
What mechanism leads to the functional closure of the ductus arteriosus in a healthy term neonate?
- A A fall in arterial oxygen tension after birth
- B A rise in circulating prostaglandin E2 levels
- C Rising arterial oxygen tension with falling prostaglandins
- D Persistence of fetal lung fluid in the alveoli
Correct answer: Rising arterial oxygen tension with falling prostaglandins
Increased oxygen and decreased prostaglandins lead to vasoconstriction of the ductus arteriosus and eventual functional closure.
What is the most accurate initial nursing intervention for a newborn with a temperature of 35.5°C in the delivery room?
- A Reassure that this temperature is acceptable for a newborn
- B Begin immediate active cooling of the newborn
- C Start warming measures: drying, skin-to-skin, and covering
- D Give a full warm bath to raise the body temperature
Correct answer: Start warming measures: drying, skin-to-skin, and covering
A temperature of 35.5°C indicates hypothermia; immediate warming measures like drying, skin-to-skin, and covering are essential for the newborn's stability.
Which newborn reflex helps assess neurologic function in the immediate post-birth period?
- A Rooting reflex
- B Moro reflex
- C Babinski reflex
- D Plantar grasp reflex
Correct answer: Moro reflex
The Moro (startle) reflex is commonly assessed after birth to evaluate neuromuscular function and central nervous system integration.
What transitional risk factor is likely increased in a term newborn born via scheduled cesarean delivery without labor?
- A Early anatomical closure of the foramen ovale
- B Delayed lung-fluid clearance with risk of transient tachypnea
- C Markedly increased fetal surfactant production
- D A reduced overall risk of neonatal hypoglycemia
Correct answer: Delayed lung-fluid clearance with risk of transient tachypnea
Cesarean delivery without labor can lead to delayed lung fluid clearance and an increased risk of transient tachypnea of the newborn.
What assessment should be performed first in the routine newborn examination within minutes after birth?
- A Careful measurement of head circumference
- B Checking vital signs: heart rate, respirations, temperature
- C Performing a heel-stick blood glucose measurement
- D Giving the newborn a first cleansing bath
Correct answer: Checking vital signs: heart rate, respirations, temperature
Vital signs are crucial immediately after birth to assess physiological adaptation and determine the need for prompt intervention.
During the first few hours after birth, what is the most accurate statement about the closure of fetal shunts in a newborn?
- A All fetal shunts close anatomically within five minutes of birth
- B Pulmonary vascular resistance stays higher than systemic resistance
- C Shunt closure is gradual; full circulatory transition takes time
- D Lung fluid remains in the alveoli for several days without clearing
Correct answer: Shunt closure is gradual; full circulatory transition takes time
Anatomical closure of fetal shunts may take hours to days after birth, and full transition may require weeks for complete adaptation of shunt flow reversal and pressure changes.
What is the primary significance of vitamin K administration in a newborn?
- A It promotes neonatal respiratory adaptation
- B It prevents hemorrhagic disease by aiding clotting factors
- C It enhances pulmonary surfactant production
- D It raises and stabilizes neonatal blood pressure
Correct answer: It prevents hemorrhagic disease by aiding clotting factors
Vitamin K administration in newborns helps prevent hemorrhagic disease by aiding in the activation of clotting factors.
A newborn's glucose level measures 30 mg/dL at 2 hours of age and the infant is asymptomatic. What is the most appropriate next step?
- A Begin an immediate intravenous glucose infusion
- B Start early feeding (breast or formula) and recheck glucose
- C Withhold treatment since low newborn levels are normal
- D Administer subcutaneous insulin to the newborn
Correct answer: Start early feeding (breast or formula) and recheck glucose
In an asymptomatic newborn with low glucose, initiation of early feeding and monitoring is the initial recommended approach.
A newborn is noted to have persistent cyanosis beyond the first hour of life despite oxygenation and warming. What possibility must the nurse consider?
- A An expected variation of normal transition
- B Persistent pulmonary hypertension or congenital heart defect
- C Early functional closure of the ductus arteriosus
- D Over-ventilation of the newborn's lungs
Correct answer: Persistent pulmonary hypertension or congenital heart defect
Persistent cyanosis suggests a potential underlying pathology like PPHN or a congenital heart defect rather than a normal transition.
What is the most appropriate action for an exclusively breastfed newborn with 8% weight loss by day 3 but otherwise well?
- A Stop breastfeeding now and switch fully to formula
- B Support lactation and monitor feeding adequacy with frequent feeds
- C Discharge the newborn home without any follow-up
- D Begin intravenous fluids to correct the weight loss
Correct answer: Support lactation and monitor feeding adequacy with frequent feeds
Supportive care with monitoring feeding adequacy and lactation support is recommended unless additional risk factors are present.
During newborn assessment, what does short periodic breathing at 6 hours of life indicate?
- A Normal periodic breathing
- B Pathologic apnea requiring immediate intervention
- C Indicates surfactant deficiency
- D Sign of congenital heart disease
Correct answer: Normal periodic breathing
Short periodic breathing (<10–15 seconds) is common in healthy newborns, indicating normal adjustment to extrauterine life.
