Question
1. When air is allowed into the pleural cavity, either from a stab wound or a blown out alveolus of the lung, the lung will collapse because of:
expansion of the rib cage
paralysis of the muscles of inspiration
the action of the muscles of expiration
the elasticity of the visceral pleura
the elasticity of the lung parenchyma
2. Which of the following arteries is used to characterize an inguinal hernia as direct or indirect?
superficial circumflex iliac
femoral
inferior epigastric
deep external pudendal
obturator
3.
Most of the small intestine receives its blood supply from branches of a single artery. The artery that supplies most of the small bowel is the:
gastroduodenal
celiac
inferior mesenteric
superior mesenteric
middle colic
4.
When removing the spleen, a surgeon must be careful not to cut one of its branches, the:
left renal
superior mesenteric
left gastric

coronary sinus and pulmonary vein
pulmonary and bronchial veins the following
superior vena cava, coronary sinus and hemiazygos vein
