  1. A medical student is running with sharp scissors to show Dr. Throckmorton that his donor has three kidneys. However, the student inadvertently stabs himself in the left lumbar region of the abdomen (should not have been running with scissors!). Dr. Throckmorton rolls his eyes and proceeds to examine the student. He informs the student that the peritoneal cavity has been punctured but the visceral peritoneum is still intact. The student realizes that the mostly likely organ punctured is the:

  1. Duodenum

  2. Jejunum

  3. Descending Colon

  4. Sigmoid Colon

  5. None of the above

They immediately suspected that the cause was a spasmodic contraction of which of the following parts of the stomach?

  1. Cardiac notch 

  2. Fundus 

  3. Lesser curvature 

  4. Pylorus 

  5. Rugae 

 

  1. Where would one put the probe on a patient when seeking to view the abdominal viscera, such as the pancreas?

  1. Transpyloric plane

  2. Interlumburcular plane 

  3. Right midclavicular line 

  4. Left midclavicular line

  5. Umbilical region

You place the probe in the transverse plane with the orientation marker facing his right side. In which order (anterior to posterior) would you encounter the abdominal viscera in this region? 

  1. Body of the pancreas, left lobe of the liver, splenic vein, superior mesenteric artery, body of the vertebrae

  2. Body of the pancreas, left lobe of the liver, superior mesenteric artery, splenic vein, body of the vertebrae 

  3. left lobe of the liver, Body of the pancreas, splenic vein, superior mesenteric artery, body of the vertebrae

  4. left lobe of the liver, Body of the pancreas, superior mesenteric artery, splenic vein, body of the vertebrae

  5. Body of the pancreas, superior mesenteric artery, left lobe of the liver, splenic vein, body of the vertebrae

  1. Many cases of female stress urinary incontinence, which affects nearly a quarter of all women, can be treated with transvaginal mid-urinary slings. This is not an entirely risk-free procedure, and occasionally patients report diminished superomedial sensation of the thigh and a weakness with adduction of the lower limb. What could have occurred during this procedure that would lead to this outcome? 

  1. Damage to the puborectalis muscle

  2. Damage to the obturator nerve

  3. Damage to the median sacral artery

  4. Damage to the perineal body

  5. Damage to the genitofemoral nerve

  1. Nemo Incognito ate only cookie dough for 3 months and began experiencing pain in his umbilical region which radiated into his right inguinal region. His friends cut him open to perform an emergency appendectomy only to discover that the appendix had long since ruptured (cautionary tale: eat fiber). Infection had most likely spread to which of the following areas?

  1. Hepatorenal recess

  2. Superior recess

  3. Inferior recess

  4. Left colic flexure

  5. Supraduodenal recess

 

  1. Appendicitis is a medical emergency that almost always requires prompt surgery to remove the appendix. Left untreated, an inflamed appendix will eventually burst, or perforate, spilling infectious materials into the abdominal cavity. Which of the following organs are LEAST likely to be affected by the infectious material resulting from a ruptured appendix?

  1. Ileum 

  2. Pancreas 

  3. Jejunum

  4. Stomach 

  5. Liver 

 

  1. The left gonadal vein drains into the _______ and the right gonadal vein drains into the _______.

  1. Left renal vein, right renal vein

  2. Left renal vein, inferior vena cava

  3. Splenic vein, right renal vein

  4. Inferior vena cava, right renal vein

  5. Inferior vena cava, Inferior vena cava
