What manifestation is an indication of increased intracranial pressure?
Hyperthermia
Confusion
Hypotension
Angina
The Correct Answer is B
Choice A reason: Hyperthermia is not a primary sign of increased intracranial pressure. It may occur in brain injury due to hypothalamic dysfunction, but increased intracranial pressure directly causes neurological symptoms like confusion due to brain compression, making this incorrect.
Choice B reason: Confusion is a hallmark of increased intracranial pressure, as elevated pressure compresses brain tissue, impairing neuronal function and cognition. This disrupts normal brain signaling, leading to altered mental status, making this the correct manifestation.
Choice C reason: Hypotension is not typical; increased intracranial pressure often causes hypertension (Cushing’s reflex) to maintain cerebral perfusion. Low blood pressure does not align with the body’s compensatory response to brain compression, making this choice incorrect.
Choice D reason: Angina, chest pain from cardiac ischemia, is unrelated to increased intracranial pressure. Intracranial pressure affects brain function, causing neurological symptoms like confusion, not cardiac pain, making this choice incorrect for this condition.

Correct Answer is A
Explanation
Choice A reason: Addison’s disease causes adrenal insufficiency, reducing aldosterone, leading to sodium loss and decreased blood volume, causing hypotension. This is a hallmark symptom due to impaired vascular tone, making this the correct choice.
Choice B reason: Hyperglycemia is not typical in Addison’s disease. Cortisol deficiency may cause hypoglycemia due to reduced gluconeogenesis, not elevated glucose, making this choice incorrect for Addison’s manifestations.
Choice C reason: Weight gain is not associated with Addison’s disease, which causes weight loss due to reduced cortisol, leading to decreased appetite and metabolism. This makes the choice incorrect.
Choice D reason: Hypernatremia does not occur in Addison’s disease. Aldosterone deficiency causes sodium loss, leading to hyponatremia, not elevated sodium, making this choice incorrect for Addison’s disease.
Correct Answer is C
Explanation
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.
