filled with blood and right before the contraction of the ventricle
....so it's the end-diastolic volume).

A 20-year-old man presents with upper gastrointestinal bleeding.
His health history indicates binge drinking on weekends. The
nurse inquires about the patients alcohol use and learns that the
patient frequently vomits violently after drinking. Which of the
following underlying causes should the nurse suspect for this
patients bleeding?
Mallory-Weiss tears
Dieulafoys lesions
Peptic ulcer disease
Stress-related erosive syndrome Correct Answers Mallory-
Weiss tears
Mallory-Weiss tears account for 8% to 15% of acute upper GIB.
These lacerations occur in the distal esophagus, at the
gastroesophageal junction, and in the cardia of the stomach.
Bleeding from Mallory-Weiss tears occurs when the tear
involves the underlying venous or arterial bed. Mallory-Weiss
tears are strongly associated with heavy alcohol use or recent
binge drinking and a prior history of forceful vomiting or
retching, or violent coughing. Patients with portal hypertension
have an increased risk for bleeding from Mallory-Weiss tears.
