Correct Answer is A

Explanation

Choice A rationale
Jaundice, a common symptom of cholecystitis, is a yellow discoloration of the skin and whites of the eyes (sclera) caused by an excess of bilirubin in the blood. The sclera is often the first place where jaundice is noticeable because the high amount of elastin in the sclera binds to bilirubin, causing a yellowish discoloration.
Choice B rationale
While nail beds can sometimes show signs of certain health issues, they are not typically used to monitor for the presence of jaundice. Jaundice primarily causes yellowing of the skin and the whites of the eyes.
Choice C rationale
The periumbilical area (around the belly button) is not typically used to monitor for the presence of jaundice. Jaundice primarily causes yellowing of the skin and the whites of the eyes.
Choice D rationale

The webbed areas of the fingers are not typically used to monitor for the presence of jaundice. Jaundice primarily causes yellowing of the skin and the whites of the eyes.

A. Intestinal obstruction. B. Fluid and electrolyte imbalance. C. Malabsorption of fat. D. Folate deficiency.

Correct Answer is B

Explanation

Choice A rationale
While intestinal obstruction can occur after any abdominal surgery, it is not the most common complication following ileostomy creation.
Choice B rationale
Fluid and electrolyte imbalance is a common complication following ileostomy surgery. This is due to the fact that the ileum, which is now rerouted to an external opening in the abdominal wall, is responsible for absorbing a significant amount of fluid and electrolytes. When it is diverted, these substances can be lost, leading to imbalances.
Choice C rationale
Malabsorption of fat is not typically a primary concern following ileostomy surgery. While malabsorption can occur in diseases affecting the ileum, it is not a direct result of the surgery itself.
Choice D rationale
Folate deficiency is not a common complication following ileostomy surgery. The terminal ileum, which is typically used to create the ileostomy, is primarily responsible for the absorption of vitamin B12, not folate.
