Q

What are the types of cells in the lung alveoli and what do they do?

A

Alveolar surface is mostly formed by two types of epithelial cells
Type-I: most of the alveolar surface (∼95%) is covered by type I cells, these are flattened cells, role in producing lung liquid

Type II: produces surfactant; a lipoprotein, forms a barrier between cells and air and would decrease the surface tension

Macrophages: which remove particles and microorganisms coming with the air

Q

How much does the weight of the uterus increase from pre pregnancy to term?

A

During normal pregnancy the weight of the uterus increase 10 to 20 fold from about 44g in the primigravida to 1100 grams at term. It increases with successive pregnancies.

Q

Where is the vasomotor centre located?

A

17
Q

What is epithelium?

A

Epithelium (epi- + thele + -ium) is one of the four basic types of animal tissue. The other three types are connective tissue, muscle tissue and nervous tissue. Epithelial tissues line the cavities and surfaces of blood vessels and organs throughout the body.

18
Q

What’s the pH of blood?

A

around 7.4.

19
Q

What are normal HB values in pregnancy?

A

10.8- 14.6 g/dl

20
Q

What is the normal increase of blood volume in pregnancy?

A

30-50%

21
Q

Which harmful materials enter the lymph vessels?

A

Bacteria
Viruses
Cancer cells
Cell debris

22
Q

Lymphocytes are a type of..

A

Leucocyte (WBC)

23
Q

Which are the four Lymphatic organs?

A

Spleen (blood filter, removes old red blood cells)
Thymus (T Lymphocytes)
Tonsils
Peyer’s patches (In the small intestine)

24
Q

What type of cell is a Macrophage?

A

Phagocytic cell

25
Q

Name three properties of the active immune system

A

Antigen specific—recognizes and acts against particular foreign substances
Systemic—not restricted to the initial infection site
Memory—recognizes and mounts a stronger attack on previously encountered pathogens

26
Q

What are Antigens?

A 
Any substance capable of exciting the immune system and provoking an immune response
Examples of common antigens
Foreign proteins (strongest)
Large carbohydrates
Some lipids
Microorganisms
27
Q

What are Haptens?

A

Incomplete antigens that cause an immune response, makes them attack the bodys own cells- causing ALLERGIES

28
Q

What deceases are screened for through blood tests during booking appointment?

A

Hep B, Syphilis, HIV, Thalassemia, Sickle cell decease (if there is family history)

29
Q

What 4 things does a newborn examination look for?

A

eyes (congenital cataract), heart (cardiac conditions), hips (hip dysplasia), undescended testes.

30
Q

What type of screening scans are offered in pregnancy?

A

Dating scan: this is the first trimester scan. The main goal of this scan is to determine if it is a single or multiple pregnancy and date the pregnancy by measuring the size of the fetus from top to bottom, which is known as crown rump length (CRL). However, at this stage it is possible to start suspecting fetal anomalies by measuring the nuchal translucency (NT): the amount of fluid under the skin behind the neck of the fetus. It is offered between 11 and 14 weeks.
Anomaly scan: This is the second trimester scan, it is offered between 18 and 21 weeks. The main goal of this scan is to screen for the 11 of conditions discussed above (it is not specifically designed for Down’s syndrome)

31
Q

which are the blood tests that are offered when screening for trisomies?

A

Combined serum test (CST): This test combines the measurement of the nuchal fold from the dating scan with the results of maternal serum hormones (bHCG and PAPP-A) to estimate the risk or chances of carrying a baby affected with any of the three trisomies. This test can only be offered between 10 and 14 weeks.

Quadruple test (QT): this test is an alternative to the CST when either, nuchal translucency cannot be obtained at the dating scan, or it is too late in the pregnancy for the CST. However, it only screens for T21 and it also has a lower detection rate. It can be used between 15 and 20 weeks and it measures four maternal serum hormones: alpha fetoprotein (AFP), bHCG, oestriol and inhibin A).

32
Q

what would a urine dipstick showing blood, leucocytes, nitrate and protein indicate?

A

UTI

33
Q

what would a urine dipstick showing protein in combination with high blood pressure indicate?

A

pre-eclampsia

34
Q

what would a urine dipstick showing ketones and glucose indicate?

A

Diabetes

35
Q

What is the greatest cause of maternal death?

A

Suicide
