A patient diagnosed with an 8 cm tumor in the ascending colon asks the nurse how the tumor grew so large without any major symptoms. How should the nurse respond to this patient?
 
  1. The pressure of the growing tumor caused the other tissue to reduce in size so the tumor could take over the space.
  2. The tumor cells bound to the tissue within the colon.
  3. The tumor cells are loosely held together so they can move about freely.
  4. The tumor cells secreted chemicals that stopped the body's normal mechanism to remove foreign tissue.

Question 2

A patient is diagnosed with hyperplasia of lung tissue. The nurse realizes that this patient's first course of treatment will most likely include:
 
  1. identification and removal of the irritant causing the hyperplasia.
  2. antibiotic therapy.
  3. chemotherapy.
  4. radiation therapy.

Answer to Question 1

Correct Answer: 1
The nurse should respond with the explanation about pressure atrophy. The pressure of a growing tumor can cause atrophy and necrosis of adjacent tissues. The malignancy then moves into the vacated space. The response that the tumor cells bound to the tissue within the colon explains how the tumor became established in the colon. The response about tumor cells moving about freely explains metastasis. The response that tumor cells secrete chemicals that stopped the body's normal phagocytic mechanism explains how the tumor was able to continue to grow.

Answer to Question 2

Correct Answer: 1
Hyperplasia is an increase in the number or density of normal cells and occurs in response to stress, increased metabolic demands, or elevated levels of hormones. Although hyperplasia often reverses after the irritating factor is eliminated, it can lead to malignancy under certain conditions. It is not clear if the patient is going to need chemotherapy or radiation therapy in the future. The first course of treatment is to identify and remove the irritant causing the hyperplasia. Antibiotic therapy is not a treatment for hyperplasia. It is not clear whether the patient will need chemotherapy or radiation therapy in the future.
