portage pathophysiology exam 2 questions
with correct answers
True/False:
Blood tests for tumor markers can make a diagnosis of cancer. Why or why not? -
| | | | | | | | | | | | | | | |
CORRECT ANSWER✔✔-False, only tissue can diagnose. Tumor markers are helpful
| | | | | | | | |
to assess response to therapy or reoccurrence.
| | | | | | |
What is the most important procedure in diagnosing the correct cancer and
| | | | | | | | | | | |
histology? - CORRECT ANSWER✔✔-tissue biopsy | | | |
Explain the TNM system: - CORRECT ANSWER✔✔-T is the size and local spread of
| | | | | | | | | | | | | |
the primary tumor.
| |
N is the involvement of the regional lymph nodes.
| | | | | | | |
M is the extent of the metastatic involvement.
| | | | | | |
1. List two signs or symptoms a patient may present with that might indicate a
| | | | | | | | | | | | | | |
cancer diagnosis: |
2. What are two systemic manifestations of cancer exhibited by cancer patients? -
| | | | | | | | | | | |
|CORRECT ANSWER✔✔-1. S+S: Bleeding; sore that doesn't heal; fluid in the
| | | | | | | | | | |
pleural, pericardial, or peritoneal spaces; chest pain, shortness of breath, cough,
| | | | | | | | | | |
abdominal discomfort or swelling. Other possible answers can include a mass or
| | | | | | | | | | | |
lump, pain (need to be specific), fatigue, fevers, weight loss
| | | | | | | | |
, 2. Systemic: Weight loss, wasting of body fat and muscle tissue, weakness,
| | | | | | | | | | | |
anorexia, and anemia, fatigue, sleep disturbances
| | | | |
1. What are the three possible goals of cancer treatment?
| | | | | | | | |
2. How does radiation kill cancer cells? - CORRECT ANSWER✔✔-1. Curative,
| | | | | | | | | | |
control, palliative |
2. Radiation therapy uses high-energy particles or waves to destroy or damage
| | | | | | | | | | | |
cancer cells. This leads to the creation of free radicals, which damage cell
| | | | | | | | | | | | |
structures. Radiation can interrupt the cell cycle process, kill cells, or damage
| | | | | | | | | | | |
DNA in the cells.
| | |
True/False:
Cell proliferation is the process of increasing cell numbers by mitotic cell division.
| | | | | | | | | | | |
- CORRECT ANSWER✔✔-true
| | |
True/False:
Cell differentiation is the process of increasing cell numbers by mitotic cell
| | | | | | | | | | | |
division. - CORRECT ANSWER✔✔-false | | |
What are two important properties that stem cells possess? - CORRECT
| | | | | | | | | | |
ANSWER✔✔-potency and self-renewal | |
