A patient is admitted with left lower thoracic rib injuries. The nurse realizes that which of the following could occur in this patient?
1. increase in red blood cell formation
2. injury to the spleen
3. reduction in T cell formation
4. reduction in filtering of foreign matter in the blood
2
Rationale: The spleen sits behind the 9th, 10th, and 11th left ribs and serves three functions: destroy injured or worn out red blood cells, store extra blood for use by the body, and store B cells. With an injury to the left lower thoracic rib area, the patient could have an injury to the spleen. An injury to the spleen will not cause an increase in red blood cell formation. Splenic injuries also do not cause a reduction in T cell formation. Lymph tissue is where the blood is filtered of foreign matter.
