While obtaining a nursing history from a client with inflammatory bowel disease, the nurse recognizes that the client most likely has ulcerative colitis rather than Crohn's disease when the client reports experiencing:

B. Large amounts of IV saline solution: This is the correct initial therapy. HHNK is characterized by severe dehydration due to osmotic diuresis resulting from hyperglycemia. Therefore, the administration of large amounts of IV saline solution is essential to correct dehydration, restore intravascular volume, and improve tissue perfusion.
A. Glucagon is typically administered to treat severe hypoglycemia, not hyperglycemia.
C. Short-acting or regular insulin is administered initially to lower blood glucose levels rapidly. Long-acting insulin formulations may be used later to maintain glycemic control once the acute phase is managed.
D. Oxygen therapy may be indicated if the client is hypoxic, but it is not the initial therapy for HHNK. The priority in HHNK is to correct dehydration and hyperglycemia through fluid resuscitation and insulin therapy, respectively.

D. The initial clinical manifestation associated with an obstruction in the duodenum is crampy abdominal pain, wavelike, and colicky. This discomfort occurs due to the blockage of the small intestine, leading to spasms and pain as the body tries to move contents past the obstruction.
A. Severe abdominal distention and cramping can occur with various gastrointestinal conditions, including an obstruction in the duodenum. However, this manifestation is not specific to duodenal obstruction and can occur with obstructions at other locations in the gastrointestinal tract.
B. Vomiting of fecal material, known as feculent vomiting, is a hallmark sign of a complete obstruction in the lower gastrointestinal tract.
C. Ribbon-like stools are more commonly associated with conditions affecting the lower gastrointestinal tract, such as colorectal cancer or irritable bowel syndrome (IBS).
