A

Radioactive sources like ribbons/seeds/capsules are placed in the body in or near the tumor

28
Q

Breast cancer risk factors (7)

A
  • Ashkenazi jewish
  • BRCA 1/2 mutation
  • Family history of breast/ovarian cancer

A
  • Hot flashes
  • Vaginal discharge
30
Q

GINA

A
  • Genetic information non-discrimination act of 2008
  • Prohibits discrimination in health coverage/employment based on genetic info
31
Q

Autosomal dominant

A
  • Mutation of a single gene pair
  • Heterozygous
  • 1 copy of mutated gene needed to get disorder
32
Q

Example of autosomal dominant disorders

A
  • Breast/ovarian cancers d/t BRCA gene mutation
  • Huntington’s Disease
  • Neurofibromatosis
33
Q

Autosomal recessive

A
  • Mutation in 2 gene pairs
  • Homozygous
  • Need 2 copies of mutation to get disorder
34
Q

Examples of autosomal recessive disorders

A
  • CF
  • Sickle cell
  • Tay-sach’s disease
35
Q

X-linked recessive

A
  • Mutation of 1 or 2 gene pairs with 1 mutated gene on the x chromosome
36
Q

Examples of x-link recessive disorders

A
  • Hemophilia
  • Duchenne muscular dystrophy
37
Q

X linked dominant

A

Dominant gene is carried on the X chromosome and only 1 allele is needed to get the disorder

38
Q

CF patio in lungs

A

Mucous builds up and clogs airways, trapping bacteria and causing damage

39
Q

GI effects of CF (5)

A
  • GERD
  • Gallstones
  • Pancreatitis
  • Constipation
  • Distal intestinal obstruction syndrome
40
Q

Pancreas pathology for CF

A

Mucous plugs duct and impairing flow of bile and pancreatic enzymes

41
Q

Pancreatic atrophy leads to

A

CF related diabetes

42
Q

Maldigestion

A

Insufficient production of lipase, amylase, protease causes poor absorption of nutrients

43
Q

Malabsorption

A

  • K
45
Q

Electrolyte imbalances in CF

A
  • Hyponatremia
  • Hypochloremia
46
Q

Liver effects in CF

A

Bile thickens in gallbladder and causing obstruction

47
Q

A
  • Meconium ileus
  • Salty sweat
  • Failure to thrive
  • Intestinal obstruction
