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 D
Explanation
Choice A reason: Genetic mutations causing insulin resistance describe type 2 diabetes. Type 1 diabetes results from autoimmune destruction of beta cells, leading to absolute insulin deficiency, not resistance, making this choice incorrect.
Choice B reason: Excessive carbohydrate intake does not cause type 1 diabetes, which is autoimmune. It may exacerbate hyperglycemia in diabetes but is not the primary cause, making this choice incorrect.
Choice C reason: Pancreatic damage from alcohol can cause pancreatitis, not type 1 diabetes. Type 1 is autoimmune, destroying insulin-producing beta cells, unrelated to alcohol-induced damage, making this choice incorrect.
Choice D reason: Type 1 diabetes is caused by autoimmune destruction of pancreatic beta cells, leading to absolute insulin deficiency. Autoantibodies target beta cells, causing hyperglycemia, making this the correct pathophysiological cause.
