What manifestation(s) occur when a person has diabetes insipidus? (Select all that apply)

Choice A reason: Compression stockings promote venous return, preventing blood stasis and deep vein thrombosis, a common immobility complication. They support circulation in immobile limbs, making this a correct preventive action.

Choice B reason: Adequate hydration prevents dehydration, maintaining blood fluidity and reducing clot risk. It also supports urinary and bowel function, preventing complications like constipation, making this a correct action for immobility.

Choice C reason: Avoiding high-fiber foods increases constipation risk, a complication of immobility. High-fiber diets promote bowel motility, so this choice is incorrect as it worsens, not prevents, immobility complications.

Choice D reason: Weight-bearing exercise maintains muscle and bone strength, preventing atrophy and osteoporosis in immobility. It also improves circulation, reducing clot risk, making this a correct preventive action.

Choice E reason: Deep breathing exercises prevent atelectasis and pneumonia by promoting lung expansion and mucus clearance in immobile individuals, improving oxygenation and reducing infection risk, making this a correct action.

Choice A reason: Melena is dark, tarry stool due to upper gastrointestinal bleeding, not greasy or foul-smelling from malabsorption. It results from digested blood, not fat malabsorption, making this choice incorrect for the described diarrhea.

Choice B reason: Small-volume diarrhea is typically due to inflammation, like in inflammatory bowel disease, not malabsorption. It lacks the greasy, foul-smelling quality of fat malabsorption, making this choice incorrect for malabsorption-related diarrhea.

Choice C reason: Steatorrhea is greasy, foul-smelling diarrhea caused by fat malabsorption, common in disorders like celiac disease or pancreatic insufficiency. Undigested fats in stool cause its characteristic appearance and odor, making this the correct choice.

Choice D reason: Osmotic diarrhea results from unabsorbed solutes, like lactose intolerance, causing watery stools, not specifically greasy or foul-smelling. It lacks the fat content of steatorrhea, making this choice incorrect for malabsorption diarrhea.
