35-Year-Old Female with Chest Trauma
Barbara Joley was in a major car accident. When EMS managed to free her from the wreckage, she was cyanotic and apneic (not breathing). Her heart was still beating, but her pulse was fast and thready. The emergency medical technician reported that when Barbara was found, her head was cocked at a peculiar angle and it looked like she had a fracture at the level of the C2 vertebra. The following questions refer to these observations.
2. NCLEX-STYLE Barbara’s cyanosis can best be explained by which of the following?
a. Trauma has caused bleeding under the skin, and the accumulated blood is turning black and blue.
b. Her lungs must be damaged, and as a result, the right side of her heart is sending blood to the body instead of the lungs.
c. The level of CO2 in her blood has increased because her breathing has stopped.
d. The level of O2 in her blood has decreased because her breathing has stopped.
Barbara is artificially ventilated and survives transport to the hospital. The admission notes include the following observations.
•Right thorax compressed; ribs 7 to 9 fractured
•Right lung pneumothorax; trachea deviation (shift) to the left
Relative to these notes:
