Question 2

A group of nursing students has entered a futuristic science contest in which they have developed a cure for cancer. Which treatment would most likely be the winning entry?
 
  a. Artificial fibronectin infusion to maintain tight adhesion of cells
  b. Chromosome repair kit to halt rapid division of cancer cells
  c. Synthetic enzyme transfusion to allow rapid cellular migration
  d. Telomerase therapy to maintain chromosomal immortality

Answer to Question 1

ANS: A
Bloodborne metastasis is the most common way for cancer to metastasize. Direct invasion and lymphatic spread are other methods. Bone marrow is not a medium in which cancer spreads, although cancer can occur in the bone marrow.

Answer to Question 2

ANS: A
Cancer cells do not have sufficient fibronectin and so do not maintain tight adhesion with other cells. This is part of the mechanism of metastasis. Chromosome alterations in cancer cells (aneuploidy) consist of having too many, too few, or altered chromosome pairs. This does not necessarily lead to rapid cellular division. Rapid cellular migration is part of metastasis. Immortality is a characteristic of cancer cells due to too much telomerase.
