Pre-rotation Test: Emergency Body Imaging

Explanation
The correct answer is Adequate CT pulmonary angiography for interpretation, Saddle pulmonary embolus is present, Pleural effusion is absent. This is because dyspnea can be a symptom of pulmonary embolism, and CT pulmonary angiography is a suitable imaging technique to diagnose and interpret the presence of a saddle pulmonary embolus. Additionally, the absence of pleural effusion suggests that there is no fluid accumulation in the pleural space, which may be relevant to the patient's condition.

Explanation
The presence of IV contrast only suggests that the study was performed using intravenous contrast, indicating that the patient may have undergone a CT scan or another imaging procedure. The presence of small bowel obstruction suggests that there is a blockage in the small intestine, which can cause abdominal pain and distension. The statement "This is likely a high-grade obstruction" indicates that the obstruction is severe.

Explanation
The presence of free air suggests that there may be a perforation in the gastrointestinal tract, allowing air to escape into the abdomen. This can be a sign of a serious injury or condition, such as a perforated ulcer or a ruptured bowel. The mention of a stab wound to the left flank further supports the possibility of internal organ damage, which could result in a perforation. The statement about the left hemidiaphragm being injured is also relevant, as the diaphragm separates the abdomen from the chest and can be affected by a stab wound in this area.
