Right Answer A
Explanation It is a typical presentation of Mallory-Weiss syndrome which is characterized by blood in vomiting due to mucosal tears at junction of oesophagus and stomach. Most common precipitating factors are retching, forceful vomiting due to excessive alcohol use, alcohol binge, hiatal hernia and eating disorders. Endoscopy is the first investigation of choice and further management depends on endoscopic findings. However, before endoscopy is done, IV fluids should be administered in any hemodynamic unstable patient.
