Question 1
What serosal cavities have been penetrated by the first arrow?
The serosal cavity that has been penetrated by the first arrow is the thoracic cavity, specifically the left side of the pleural cavity. The pleural cavity encloses the lung, and each pleural cavity is lined with pleura, which is “a shiny slippery serous membrane” that “reduces friction as the lung expands and recoils during breathing” (Martini et al., 2018, p.19). The pleural cavity is composed of two layers: the parietal pleura and visceral pleura. According to Charalampidis et al. (2015), “the parietal pleurae are highly sensitive to pain, while the visceral pleura are not, due to the lack of sensory innervation,” so the first arrow that penetrated will more than likely cause the patient excruciating pain.

Include the effect on the Hematocrit and Hemoglobin values. Due to the penetrating trauma and probable blood loss sustained by the pleural cavity, the hematocrit, which is volume of packed red cells in the body, will show that the patient will have less red blood cells circulating within the body, and the hemoglobin, the protein responsible for the red blood cell’s ability to transport oxygen and carbon dioxide, will not be enough due to blood loss (Martini et al., 2018, pp. 531-533).
