Template Quiz Published on August 30, 2020 by ehudspeth Thoracic Wall, Pleura & Lungs Your friend tells you that they are worried because their physician diagnosed them with a supernumerary rib located at L1. They ask you what symptoms they should be expecting from this condition. What do you tell them? The rib will compress the lumbosacral plexus and most likely result in sciatica The rib will compress the internal pudendal artery and lead to ischemia Not to worry, an extra rib at L1 is usually asymptomatic The rib will compress the subclavian artery, resulting in ischemia The rib will compress the spinal nerve T12 Which of the following correctly describes the flow of blood from the aorta to the right anterior intercostal arteries? Aorta → Right subclavian artery → Right internal thoracic artery → Anterior intercostal arteries Aorta → Brachiocephalic trunk → Right Subclavian artery → Right superior thoracic artery → Anterior intercostal arteries Aorta → Right subclavian artery → Right superior thoracic artery → Anterior intercostal arteries Aorta → Brachiocephalic trunk → Right costocervical trunk → Right internal thoracic artery → Anterior intercostal arteries Aorta → Brachiocephalic trunk → Right Subclavian artery → Right internal thoracic artery → Anterior intercostal arteries Your friend from class seems to be experiencing some medical school syndrome and tells you that they have diagnosed themself with pleural mesothelioma. In order to put their mind at ease, you remind them that mesothelioma is a fairly rare cancer and that they would probably had to have been exposed to which of the following carcinogens? Asbestos Tobacco Chlordane Arsenic Tell them that they may be entitled to financial compensation Tube thoracostomy is the insertion of a tube (chest tube) into the pleural cavity to drain air, blood, bile, pus, or other fluids. The tube is usually inserted in the fourth or fifth intercostal space in the mid-to-anterior axillary line. Which of the following layers of pleura must the chest tube penetrate in order to perform this procedure? Mediastinal parietal pleura Diaphragmatic parietal pleura Costal parietal pleura Visceral pleura C & D A patient comes into your clinic complaining of dyspnea (difficulty breathing). You want to do some medical imaging to help your diagnosis so you decide to take an x-ray. You ask the patient to take a deep breath and then acquire the following image. What is the diagnosis? The patient has fluid in the right lung preventing them from breathing correctly The patient has damaged their right phrenic nerve, leading to partial paralysis of the diaphragm The patient has inflammation of the liver causing the right lung to be compressed The patient has a pneumothorax (collapsed lung) No diagnosis, the patient is completely normal.

What do you tell them? The rib will compress the lumbosacral plexus and most likely result in sciatica The rib will compress the internal pudendal artery and lead to ischemia Not to worry, an extra rib at L1 is usually asymptomatic The rib will compress the subclavian artery, resulting in ischemia The rib will compress the spinal nerve T12 Thoracentesis is a procedure in which a needle is inserted into the pleural space between the lungs and the chest wall. This procedure is done to remove excess fluid from the pleural space to help you breathe easier. Which of the following describes the most appropriate location of needle insertion when performing this procedure at the midclavicular line? The lower portion of the 6th intercostal space The upper portion of the 6th intercostal space The lower portion of the 7th intercostal space The upper portion of the 7th intercostal space The lower portion of the 8th intercostal space Which of the following correctly describes the flow of blood from the aorta to the right anterior intercostal arteries? Aorta → Right subclavian artery → Right internal thoracic artery → Anterior intercostal arteries Aorta → Brachiocephalic trunk → Right Subclavian artery → Right superior thoracic artery → Anterior intercostal arteries Aorta → Right subclavian artery → Right superior thoracic artery → Anterior intercostal arteries Aorta → Brachiocephalic trunk → Right costocervical trunk → Right internal thoracic artery → Anterior intercostal arteries Aorta → Brachiocephalic trunk → Right Subclavian artery → Right internal thoracic artery → Anterior intercostal arteries Which of the following nodes would have to be present for a patient to be diagnosed with hilar lymphadenopathy? Tracheal Tracheobronchial Bronchopulmonary Pulmonary Brachiomediastinal Which of the following could have caused the abnormality in the image below? Splenomegaly Paralysis of the left phrenic nerve Paralysis of the right phrenic nerve Paralysis of both phrenic nerves Pericardial effusion Which of the following is an example of a parasympathetic function of the pulmonary plexus? Increasing airflow Decreasing blood flow to lungs Coughing when there is an irritation Sensing stretch to prevent overfilling of lungs Increased oral secretions Which of the following rib abnormalities would be the most problematic? Absence of the 12th Absence of the 11th Cervical Rib Lumbar Rib None of the above would cause any problem When attempting to do a thoracentesis in the 8th intercostal space, where will you anesthetize? Only the 8th intercostal space The 8th and the 9th intercostal space Only the 9th intercostal space The phrenic nerve/diaphragm interaction All 12 intercostal spaces The first rib is atypical in that it can be described as the broad and sharpest of the 12 ribs. It also is noted to have grooves for both which of the following? First Intercostal Nerve & First Intercostal Artery First Subcostal Muscles & First Innermost Intercostal Muscles Subclavian Vein & Subclavian Artery Manubrium & Costoclavicular Cartilage Intercostal Vasculature & Collateral Vasculature Donald has bacterial bronchitis. This has caused an excess of non-serous fluid to build up in his lungs causing him tightness in his chest and a persistent productive cough. Which of the following categories can bronchitis be classified as? Hemothorax Hydrothorax Pyothorax Chylothorax Pneumothorax After running a marathon, Mary was in tripod position heavily breathing. Which of the following is ensuring that she is not rupturing a lung by overfilling it? Vagus Nerve Cough Reflex Chemoreception Hering Breuer Reflex Nociception Which of the following would cause hilar lymphadenopathy? Breast cancer Tuberculosis Punctured lung Hemothorax Pneumothorax Which of the following is a cause of clubbed nails? COPD Leprosy Cystic fibrosis Kidney failure Type II diabetes Time is Up!
