An older adult patient asks the nurse why so many of her friends are developing cancers. The nurse responds best when answering
 
  a. Cancer cells generally develop as a result of prolonged exposure to external agents.
  b. The longer we live the more exposure we have to environmental toxins.
  c. Aberrant growth seems to be the risk factor in the older adult that is not well understood.
  d. As we age, our cells are less able to re-gulate replication appropriately.

Question 2

A patient is brought to the emergency department after falling while shoveling snow. The pa-tient's core temperature is 92?0F (33.3?0C). What rewarming measures does the nurse prepare to initiate?
 
  a. Warm blankets
  b. Warm heating lamps
  c. Peritoneal dialysis
  d. Warmed intravenous (IV) solutions

Answer to Question 1

D
The aging cell has a tendency toward aberration or abnormalcy as it replicates. Aberrant cell growth is related to failure of growth control mechanisms, which leads to less cell regulation during replication. Cancer occurs more commonly in replicating than in nonreplicating cell groups, which suggests that changes in internal cellular control mechanisms give rise to cancer.

Answer to Question 2

D
A core temperature this low requires active internal rewarming. Warmed IV solutions are appro-priate. Blankets and a heating lamp are appropriate for mild hypothermia. Peritoneal dialysis is reserved for severe cases with cardiac instability.
