Correct Answer is B

Explanation

Choice A reason:

Sudden thirst, unrelieved by oral fluid administration, may indicate dehydration, but it is not specific to a recurrence of upper GI bleeding.

Choice B reason:

This is the correct answer. Tachycardia (rapid heart rate), hypotension (low blood pressure), and tachypnea (rapid breathing) are signs of potential recurrence of upper GI bleeding and should be closely monitored.

Choice C reason:

Diaphoresis (excessive sweating) and sudden onset of abdominal pain could be indicative of various conditions, but they are not specific to a recurrence of upper GI bleeding.

Choice D reason:

Tarry, foul-smelling stools (melena) are indicative of upper GI bleeding. However, in this scenario, the bleeding has been controlled, so this is not an expected sign of recurrence.

A. Chronic blood loss B. Intestinal malabsorption syndrome C. Dietary iron restrictions D. Intestinal parasites

Correct Answer is A

Explanation

Choice A reason:

Chronic blood loss is a common complication of ulcerative colitis. Inflammation and ulcers in the colon can lead to ongoing bleeding, resulting in iron deficiency anemia.

Choice B reason:

While intestinal malabsorption can occur in some gastrointestinal disorders, it is not a primary mechanism in ulcerative colitis. In ulcerative colitis, the main factor leading to anemia is chronic blood loss.

Choice C reason:

Dietary iron restrictions may exacerbate anemia in individuals with ulcerative colitis, but the primary cause of anemia in this condition is chronic blood loss.

Choice D reason:

Intestinal parasites are not a common factor in ulcerative colitis and are not a primary cause of anemia in this condition. Chronic blood loss is the main contributing factor.
