1In neonates, the patent blood vessel that shunts blood from the pulmonary artery to the aorta is known as the [blank_start]ductus arteriosus[blank_end]
- Aductus arteriosus
2At what point in gestation do the alveoli develop?
[blank_start]36 weeks[blank_end] gestation- A36 weeks
- B30 weeks
- C34 weeks
3Later in the pregnancy, the amniotic fluid is mostly made up of which fluid produced by the foetus?
Foetal [blank_start]urine[blank_end]- Aurine
4Which organ(s), which allow processing of amniotic fluid when swallowed by the foetus, plays an important role in amniotic fluid recycling?
- AThe kidneys
- BThe liver
- CThe stomach
- DThe pancreas
5Which maternal antibody is passed from mother to baby via the placenta?
- AIgG
- BIgA
- CIgE
- DIgD
6The ductus venosus allows bypassing of which organ by the foetal blood before birth?
The [blank_start]liver[blank_end]- Aliver
7The foramen ovale, which closes after birth, causes a [blank_start]right to left[blank_end] shunting of blood whilst the foetus is still inside the uterus
- Aright to left
- Bleft to right
8No blood whatsoever is transported to the lungs in the growing foetus
- ATrue
- BFalse
9In adults, the remnant of the ductus venosus is called the [blank_start]ligamentum teres[blank_end] of the liver
- Aligamentum teres
10In adults, the remnant of the ductus arteriosus is known as the [blank_start]ligamentum arteriosus[blank_end]
- Aligamentum arteriosus
11Unlike anywhere else in the body, [blank_start]oxygen[blank_end] acts as a vasoconstrictor in the ductus arteriosus thus contributing towards its closure following birth.
[blank_start]A reduction[blank_end] in the level of prostaglandins in the blood also contributes towards ductus arteriosus closure following birth- AA reduction
- BAn increase
- Coxygen
- Dnitrogen
- Ecarbon dioxide
12Oxygen typically acts as a [blank_start]vasodilator[blank_end] in the body's blood vessels
- Avasodilator
- Bvasoconstrictor
13The foramen in the foetal heart allowing right to left shunting of blood via the atria is called the foramen [blank_start]ovale[blank_end]
- Aovale
14Which form of fat is produced in excess by the foetus in the final stages of pregnancy in order to facilitate thermogeneration upon entrance to the world?
- AWhite fat
- BBrown fat
15Fat Types:
[blank_start]White fat[blank_end] = Good for energy storage
[blank_start]Brown fat[blank_end] = Good for quick breakdown and energy release (e.g. thermogeneration)- ABrown fat
- BWhite fat
16The fat pad that typically generates between the scapulae of the foetus in late pregnancy typically consists of which type of fat?
[blank_start]Brown[blank_end] fat- ABrown
- BWhite
17One of the main worries for the baby during late pregnancy/labour/birth is the development of hypoxia. Hypoxia in a foetus would likely lead to ...
- AMetabolic acidosis
- BMetabolic alkalosis
- CRespiratory acidosis
- DRespiratory alkalosis
18Persistence of the foetal circulation (patent foramen ovale/ductus arteriosus/etc) can lead to the pulmonary vessels not opening properly thus causing persistent pulmonary [blank_start]hypertension[blank_end] of the newborn (PPHN)
- Ahypertension
- Bhypotension
19Persistent Pulmonary Hypertension of the Newborn is investigated by measuring the oxygen saturations of the hands and feet.
In a case of PPHN:
The [blank_start]hands[blank_end] will have a near normal O2 saturation
The [blank_start]feet[blank_end] will have an abnormal O2 saturation- Afeet
- Bhands
- Chands
- Dfeet
20Management of PPHN is via multiple processes, one of which is ventilation using oxygen and which other vasodilating molecule?
[blank_start]Nitric oxide[blank_end]- ANitric oxide
21Inotropes such as [blank_start]adrenaline[blank_end] are also given in order to raise the [blank_start]systemic[blank_end] blood pressure above the [blank_start]pulmonary[blank_end] pressure thus allowing the blood to force itself into the pulmonary circulation, hopefully solving the problem.
- Aadrenaline
- Boxytocin
- Coxygen
- Dmagnesium sulphate
- Esystemic
- Fpulmonary
- Gpulmonary
- Hsystemic
22Transient [blank_start]tachypnoea[blank_end] occurs in infants when there is insufficient clearing of fluid from the foetal lungs
- Atachypnoea
23Neonates typically do not shiver in order to produce heat. Preterm neonates are therefore more likely to become hypothermic due to a lower content of [blank_start]brown fat[blank_end]
- Abrown fat
- Bwhite fat
- Cglycogen
24The dark green substance forming the first faeces of a newborn infant is called the [blank_start]meconium[blank_end]
- Ameconium
25When something touches a neonate's mouth, it instinctively opens it's mouth and tries to latch onto it. What is this reflex called?
The [blank_start]rooting[blank_end] reflex- Arooting
26Noramly breastfeeding should involve the neonate's tongue pushing the nipple against the [blank_start]soft[blank_end] palate in order to facilitate lactation
- Asoft
- Bhard
27Foetal blood is [blank_start]more[blank_end] concentrated in haemoglobin than adult blood
- Amore
- Bless
28For which of the following reasons does Foetal Haemoglobin have a higher affinity for oxygen?
- AIt does not interact with 2,3-DPG
- BIt does interact with 2,3-DPG
- CIt does not respond to changes in temperature
- DIt does respond to changes in temperature
- EIt does not respond to changes in CO2 content of the foetal blood
- FIt does respond to changes in CO2 content of the foetal blood
29Foetal haemoglobin is produced in the [blank_start]liver[blank_end]
Adult haemoglobin is produced in the [blank_start]bone marrow[blank_end]- Aliver
- Bbone marrow
30Newborns can typically become anaemic as the foetal haemoglobin is broken down faster than the adult haemoglobin can be produced to replace it
- ATrue
- BFalse
31Haemoglobin breakdown yields which substance?
[blank_start]Bilirubin[blank_end]- ABilirubin
32Accumulation of bilirubin in the foetal circulation causes neonatal [blank_start]jaundice[blank_end]
- Ajaundice
33Foetal jaundice is a case of accumulation of [blank_start]unconjugated[blank_end] bilirubin
- Aunconjugated
- Bconjugated
