Question 1

The first arrow in the patient penetrated the pleural cavity. This is a serous membrane covering the walls of various organs of the abdominopelvic cavities and the thoracic cavities. They are essential for secreting lubricants which reduce the amount of friction from excessive muscle movement within the body (D’Arienzo et al., 2016).

Question 2

Typically, the autonomic nervous system is paramount in controlling involuntary functions within the body. These automatic actions involve the heartbeat and breathing. Therefore, autonomic dysfunction can adversely affect heart rate and blood pressure (Glynos et al., 2015).  As a result of the arrow injury and attack, the patients' pulse will be rapid and low as a result of shock.

Additionally, the patient's blood pressure will also reduce. However, the patient's body temperature is expected to decrease because the blood will be shunted towards critical organs in the body (Bassi et al., 2015).  The patient's respiratory rate of the patient will increase while at the same time remaining shallow.

Question 3

The trajectory of the first arrow to enter the patient can be described as posterosuperior and falling along the axial plane. However, from a posterior and anterior angle, the organs expected to be affected will be both the posterior and anterior skin (Duan et al., 2015). Additionally, the lungs and the heart are the most crucial organs that will be affected by the arrow. Also, since the second injury is located in the posterior triangle within the neck, contents of the posterior triangle situated within the neck will also be affected by the arrow. Its contents include; supraclavicular lymph nodes, brachial plexus, spinal accessory nerve and occipital lymph node (Duan et al., 2015).

Question 4

The cardiovascular system is composed of different tissues and organs functioning as a unit.  The system has three necessary functions, which include; removal of toxic wastes from the body, transport of oxygen, hormones, and nutrients to different parts of the body (Fritz et al., 2018). However, when Hematocrit levels are on the rise above optimum, the result is blood thickening making it impossible for the heart to perform its duty to pump blood to the rest of the body. This can easily lead to a heart attack.  On the other hand, Hemoglobin can be described as a red protein essential in the transport of oxygen in vertebrates. Blood loss can cause a condition called anemia when not treated appropriately.

Question 5

Neuromuscular Effects of the Second Arrow

Based on the physical examination done on the patient, the second arrow pierced through the posterior cervical triangle. Apart from pain resulting from the piercing of the patient’s muscles, other neuromuscular effects might have also resulted from the injury. First of all, the suprascapular nerve passes through this region and its function is to innervate two rotator curve muscles of the shoulder which include supraspinatus and infraspinatus (D’Arienzo et al., 2016). The supraspinatus performs different functions on the arm such as enabling abduction, flection, and stabilizing of the humerus in the glenoid fossa to prevent dislocation during movement. Therefore, injury to the suprascapular nerve affects the patient’s ability
