[pragya sharda]

When trying to explain to a patient diagnosed with a benign bone tumor, the nurse should emphasize the fact that benign tumors primarily
 
  A)
  grow rapidly and can spread to the surrounding tissue.
  B)
  cause growth of other tumors as they spread their cancer cells into the bloodstream.
  C)
  tend to grow very slowly without destroying the supporting tissue.
  D)
  occur as a result of tumors in other areas of the body metastasizing into the bone.

Question 2

Following exposure to poison oak while camping, a 20-year-old male is experiencing pruritus as a consequence of his immune response to irritants in the plant. What physiological process best accounts for his complaint?
 
  A)
  His body is communicating a low-level pain response as a protective measure.
  B)
  Free nerve endings are initiating an itch-specific signal to the somatosensory cortex.
  C)
  Local irritation of Langerhans cells is sending signals by way of myelinated type C nerve fibers.
  D)
  Ruffini corpuscles are transmitting the message of pruritus to the cerebral cortex.

Answer to Question 1

Ans:
C

Feedback:

Benign tumors, such as osteochondromas, tend to grow rather slowly and usually do not destroy the supporting or surrounding tissue or spread to other parts of the body (metastasize). Malignant tumors tend to grow rapidly, destroy supporting or surrounding tissue, or spread to other parts of the body through the bloodstream or lymphatics.

Answer to Question 2

Ans:
B

Feedback:

It is generally agreed that itch is a sensation that originates in free nerve endings in the skin, is carried by small myelinated type C nerve fibers to the dorsal horn of the spinal cord, and is then transmitted to the somatosensory cortex via the spinothalamic tract. Itching is no longer considered to be a low-level pain response. Ruffini corpuscles and Langerhans cells are not noted to play a role in pruritus.
