ou want to find the balance, A. First, list the other variables in the equation A=Pert and specify their given values. P=\$400.00 r=11%=0.11 t=2 years Now plug these values into the equation and solve for A. A = Pert = 400e0.112 Plug in P=400, r=0.11, and t=2 = 400e0.22 ≈ 498.43069223 ≈ \$498.43 Round to the nearest cent To the nearest cent, the balance is \$498.43.

Question:

Serving as a resident in emergency medicine a patient is admitted with an aortic aneurysm that appears to impact on the left vagus nerve. Discuss the course of the left vagus nerves in the thorax, and mention how perturbation of this nerve might be manifested in clinical symptoms.

The left vagus nerve enters the superior aperture of the thoracic cavity with the left common carotid artery. Within the superior mediastinum the nerve crosses lateral to the arch of the aorta near the level of the ligamentum arteriosum. The left recurrent laryngeal nerve branches at this level and circles the aorta immediately posterior to the ligamentum arteriosum. It then ascends along a groove between the trachea and the esophagus. Cardiac branches leave the vagus to contribute to the superficial and deep cardiac plexuses and pulmonary plexuses. Inferior to the arch of the aorta, the left vagus courses inferiorly and posteriorly and passes posterior to the root of the lung. Upon reaching the esophagus the vagus nerve ramifies and contributes to the esophageal plexus of nerve fibers. Near the diaphragm the majority of fibers from the left vagus nerve converge to form the anterior vagal trunk. This trunk passes through the esophageal hiatus to enter the abdomen.
