  1. 1What is the process of physiologic change in the newborn infant, that begins in utero in preperation for the change from intrauterine placental support to extrauterine self-maintenance.
    1. ATransition
    2. BTranslation
    3. CAdaptation
    4. DRecruitment
  2. 2Label the below fetal circulationImage for question 2
    1. ADuctus Arteriosus
    2. BUmbilical arteries
    3. CUmbilical vein
    4. DLiver
    5. EDuctus Venosus
    6. FForamen Ovale
  3. 3The Ductus Venosus is located in the [blank_start]liver[blank_end]. It connects the umbilical vein to the left [blank_start]hepatic vein[blank_end] or [blank_start]inferior vena cava[blank_end].

    At birth, the sphincter close to the umbilical vein [blank_start]constricts[blank_end] and the ductus venosus [blank_start]closes[blank_end]. This becomes the [blank_start]ligamentum venosum[blank_end].
    1. Aliver
    2. Bheart
    3. Clarge intestime
    4. Dhepatic vein
    5. Eumbilical arteries
    6. Finferior vena cava
    7. Gconstricts
    8. Hdilates
    9. Icloses
    10. Jopens
    11. Kligamentum venosum
  4. 4Blood continues to travel up the inferior vena cava, and enters the [blank_start]right atrium[blank_end] of the heart.
    Some blood goes to the [blank_start]right ventricle[blank_end], then to the pulmonary arteries. Only a small amount goes to the maturing lungs. The rest of blood is shunted away from lungs by the [blank_start]ductous ateriosus[blank_end] back to the aorta.
    Most of the blood in the right atrium passes to the [blank_start]left atrium[blank_end] through the [blank_start]foramen ovale[blank_end]. From the left atrium it flows to the left ventricle, and is then pumped to the [blank_start]aorta[blank_end].

    1. Aright atrium
    2. Bright ventricle
    3. Cductous arteriosus
    4. Dleft atrium
    5. Eforamen ovale
    6. Faorta
  5. 5The Foramen Ovale is a small opening in the septum of the heart and completely bypasses the non-functioning lungs.
    1. ATrue
    2. BFalse
  6. 6Eventually the ductus arteriosus becomes the [blank_start]ligamentum arteriosum[blank_end], and the foramen ovale becomes the [blank_start]fossa ovalis[blank_end].
    1. Aligamentum arteriosum
    2. Bligamentum vanosum
    3. Cligamentum teres
    4. Dfossa ovalis
  7. 7Factors that will initiate the first breath and lung expansion of the neonate are:
    1) [blank_start]Compression[blank_end] of the chest wall during vaginal delivery AND [blank_start]recoil[blank_end] of the chest wall immediately after birth;
    2) [blank_start]Chemoreceptor[blank_end] stimulation by the decrease in O2 and increase in CO2 in blood;
    3) [blank_start]Sensory stimuli on the skin[blank_end] (touch, pressure and low environmental temperature);
    4) Stimulation of the senses [blank_start]by light and noise[blank_end].
    1. ACompression
    2. Brecoil
    3. CChemoreceptor
    4. DSensory stimuli on the skin
    5. Eby light and noise
  8. 8Which of the below are ways in which a neonate can lose heat?
    1. Aevaporation
    2. Bconvection
    3. Cconduction
    4. Dradiation
  9. 9At the time of birth blood effects the [blank_start]opening[blank_end] of the alveoli and clears [blank_start]lung fluid[blank_end] from the alveoli.

    During fetal life, the alveoli are filled with lung fluid. They are small and not expanded.

    At birth, capillaries fully fill with [blank_start]blood[blank_end] for the first time, expanding so they become [blank_start]erect[blank_end] and actively [blank_start]open[blank_end] the alveoli. This process is called [blank_start]recruitment[blank_end].

    Lung fluid is not [blank_start]absorbed[blank_end] into ‘lung tissue’ which is an area for active gaseous exchange. The only way to clear lung fluid is through the intricate circulation established within the lung tissue immediately after birth.

    The higher [blank_start]colloidal osmotic pressure[blank_end] of the blood in the capillaries surrounding each alveolus [blank_start]draws[blank_end] the fluid from the lung.
    1. Aopening
    2. Blung fluid
    3. Cblood
    4. Derect
    5. Eopen
    6. Frecruitment
    7. Gabsorbed
    8. Hcolloidal osmotic pressure
    9. Idraws
  10. 10Signs of normal transition are:
    1. AIt is normal to lose heat through evaporation and conduction of not prevented
    2. BIt is normal for peripheral circulation to be delayed, giving ‘blue’ hands and feet
    3. CBreathing adequate by 90 seconds
    4. DHeart rate of 120 – 150bpm
    5. EMay be born blue, but rapidly becomes pink
    6. FCries or gasps within seconds
