1. Jenny Myers. Tutorial. Diabetes.
We will give this a quick run-through and I’ll attempt to
answer any questions.
There is no option list to
make you behave in a model fashion – best technique is to decide the correct
answer before looking at the option list.
Scenario
1. A woman is 8 weeks pregnant and a carrier of CF. Her husband is
Caucasian. What is the risk of the child having CF?
Scenario
2. A healthy woman attends for pre-pregnancy counselling. Her brother has CF.
Her husband is Caucasian and has a negative CF screen. What is the risk of them
having a child with CF?
Scenario
3. A healthy woman is a carrier of CF. She attends for pre-pregnancy
counselling. Her husband has CF. What is the risk of them having a child with
CF?
Scenario
4. A healthy woman attends for pre-pregnancy counselling. Her sister has
had a child with CF. What is her risk of being a carrier?
Scenario
5. A woman attends for pre-pregnancy counselling. Her mother has CF.
What is the risk that she is a carrier?
Scenario
6 . A woman attends for pre-pregnancy counselling. Her mother has CF.
The partner’s risk of being a carrier is 1 in X. What is the risk that
she will have a child with CF?
Scenario
7. A healthy Caucasian woman is 10 weeks pregnant. Her husband is a carrier
of CF. Which test would you arrange?
Scenario
8. A woman attends for pre-pregnancy counselling. She has read about
diagnosing CF using cffDNA from maternal blood. Is it possible to test for CF
in this way?
Scenario

affected child?
Scenario
10. A woman and her husband are carriers of CF. What can they do to reduce
the risk of having an affected child?
Scenario
11. A woman and her husband are carriers of CF. Can CVS exclude an affected
pregnancy?
Scenario
12. A woman has CF, her husband is a carrier. What is their risk of an
affected child?
Scenario
13. A woman with CF delivers a baby at term. She has been advised not to
breastfeed because her breast milk will be protein-deficient due to
malabsorption. Is this advice correct?
Scenario
14. A woman with CF delivers a baby at term. She has been advised not to
breastfeed because her breast milk will contain abnormally low levels of
sodium. Is this advice correct?
