Answer
  • True
  • False

Question 2

Question
In patients with cirrhosis, any upper gastrointestinal bleeding associated with hemodynamic changes should be considered to be variceal in origin until proven otherwise.

Only 50 percent of patients with variceal hemorrhage stop bleeding spontaneously
Answer
  • True
  • False

Question 5

Question
Cuando la presión portal pasa de 10 mmHg se incrementa potencialmente el desarrollo de colaterales.
Answer
  • True
  • False

Question 6

Question
Se define como hipertensión portal un gradiente de presión venosa hepática mayor a 5 mmHg, y el valor de 12 mmHg es un factor de riesgo para predecir hemorragia variceal.
Answer
  • True
  • False

Question 7

Question
a hepatic venous pressure gradient >20 mmHg is associated with a greater risk of continued or recurrent bleeding
Answer
  • True
  • False

Question 8

Question
50 percent of all early rebleeding episodes occur within the first 10 days
Answer
  • True
  • False

Question 9

Question
The risk of bleeding and of death in patients who survive six weeks is similar to that in patients with cirrhosis of equivalent severity who have never bled
Answer
  • True
  • False

Question 10

Question
Acute bleeding from varices is associated with approximately 15 to 20 percent 30-day mortality
Answer
  • True
  • False

Question 11

Question
Platelet counts often drop within the first 48 hours after a bleed and may necessitate platelet transfusions if values below 50,000/mm3
Answer
  • True
  • False

Question 12

Question
Bacterial infections are present in up to 20 percent of patients with cirrhosis who are hospitalized with gastrointestinal bleeding
Answer
  • True
  • False

Question 13

Question
effectiveness of prophylactic antibiotics in patients with cirrhosis hospitalized for bleeding suggest an overall reduction in infectious complications and decreased mortality
Answer
  • True
  • False

Question 14

Question
A systematic review that included eight placebo-controlled trials with a total of 864 patients found the antibiotics were associated with a significant reduction in mortality (RR 0.75, 95% CI 0.55 to 0.95) and bacterial infections (RR 0.40, 95% CI 0.32 to 0.51) including bacteremia, pneumonia, spontaneous bacterial peritonitis, and urinary tract infections
Answer
  • True
  • False

Question 15

Question
patients with cirrhosis who present with upper GI bleeding (from varices or other causes) should be given prophylactic antibiotics, preferably before endoscopy
Answer
  • True
  • False

Question 16

Question
fOR PREVENTION OF INFECTIONS, intravenous ceftriaxone (1 g/day for seven days), which was superior to norfloxacin in a randomized controlled trial [
Answer
  • True
  • False

Question 17

Question
Short-term (maximum seven days) antibiotic prophylaxis should be instituted in any patient with cirrhosis and GI hemorrhage.
Answer
  • True
  • False

Question 18

Question
Among patients with cirrhosis, varices form at a rate of 5 to 15 percent per year, and one-third of patients with varices will develop variceal hemorrhage
Answer
  • True
  • False

Question 19

Question
Treatment with endoscopic variceal ligation decreases the risk of rebleeding to approximately 30 percent, and the risk of death to approximately 25 percent.
Answer
  • True
  • False

Question 20

Question
Endoscopic sclerotherapy is associated with a decrease in the risk of rebleeding to 40 to 50 percent, and a decrease in the risk of death to 30 to 60 percent
Answer
  • True
  • False

Question 21

Question
Pharmacologic therapy should not be delayed pending confirmation that the source of bleeding is indeed from varices
Answer
  • True
  • False

Question 22

Question
pharmacologic therapy typically consists of an octreotide bolus (50 mcg intravenous [IV]) followed by a continuous infusion (50 mcg IV per hour).
Answer
  • True
  • False

Question 23

Question
Terlipressin is administered at an initial dose of 2 mg IV every four hours and can be titrated down to 1 mg IV every four hours once hemorrhage is controlled
Answer
  • True
  • False

Question 24

Question
Pharmacologic therapy is typically continued for three to five days following cessation of bleeding
Answer
  • True
  • False

Question 25

Question
The goal should be to perform an upper endoscopy after fluid resuscitation and within 12 hours of presentation
Answer
  • True
  • False

Question 26

Question
If the bleeding cannot be controlled endoscopically, treatment options include transjugular intrahepatic portosystemic shunt (TIPS) placement or surgical shunting
Answer
  • True
  • False

Question 27

Question
terlipressin is the only agent individually shown to reduce mortality
Answer
  • True
  • False

Question 28

Question
— Vasopressin can achieve initial hemostasis in 60 to 80 percent of patients, but has only marginal effects on early rebleeding episodes and does not improve survival from active variceal hemorrhage [12].
Answer
  • True
  • False

Question 29

Question
terlipressin is released in a slow and sustained manner, permitting its administration via intermittent injections.
Answer
  • True
  • False

Question 30

Question
terlipressin has been associated with hyponatremia,
Answer
  • True
  • False

Question 31

Question
A study comparing the acute hemodynamic effects of terlipressin to octreotide in stable patients with cirrhosis found a sustained effect of terlipressin on portal pressure and blood flow compared with only a transient effect from octreotide
Answer
  • True
  • False

Question 32

Question
Somatostatin inhibits the release of vasodilator hormones such as glucagon [20], indirectly causing splanchnic vasoconstriction and decreased portal inflow.
Answer
  • True
  • False

Question 33

Question
the most consistently delocteotride observed is the decrease in collateral flow (azygos flow)
Answer
  • True
  • False

Question 34

Question
While somatostatin and octreotide help achieve hemostasis and prevent rebleeding, neither has a clearly established benefit on mortality [
Answer
  • True
  • False

Question 35

Question
A systematic review found that combination therapy with somatostatin or octreotide and endoscopic variceal ligation improved the five-day success rate compared with endoscopic variceal ligation alone
Answer
  • True
  • False
