What is the best description of Addison's disease?
It is caused by the overproduction of parathyroid hormone by the parathyroid gland.
It is caused by a lack of insulin production by the pancreas.
It is caused by the lack of cortisol and aldosterone production by the adrenal gland.
It is caused by the overproduction of growth hormone by the pituitary gland.
The Correct Answer is C
Choice A reason: Overproduction of parathyroid hormone causes hyperparathyroidism, leading to hypercalcemia and bone issues. Addison’s disease involves adrenal insufficiency, reducing cortisol and aldosterone, not parathyroid dysfunction, making this choice incorrect as it describes a different endocrine disorder unrelated to adrenal function.
Choice B reason: Lack of insulin production by the pancreas describes type 1 diabetes, not Addison’s disease. Addison’s disease affects the adrenal glands, causing deficiencies in cortisol and aldosterone, leading to metabolic and electrolyte imbalances, making this choice incorrect for the described condition.
Choice C reason: Addison’s disease is adrenal insufficiency, characterized by inadequate cortisol and aldosterone production due to adrenal gland damage (e.g., autoimmune). This leads to symptoms like fatigue, hypotension, and hyperkalemia, accurately describing the pathophysiology and making this the correct choice.
Choice D reason: Overproduction of growth hormone causes acromegaly or gigantism, not Addison’s disease. Addison’s involves adrenal hormone deficiency, not pituitary overactivity. Growth hormone excess affects growth and metabolism, not adrenal function, making this choice incorrect for Addison’s disease.

Correct Answer is D
Explanation
Choice A reason: Lack of appetite is not typical in type 1 diabetes, where increased appetite (polyphagia) occurs due to glucose deprivation in cells. Weight loss is more characteristic, making this choice incorrect.
Choice B reason: Oliguria (low urine output) is not a feature of type 1 diabetes, which causes polyuria due to osmotic diuresis from hyperglycemia. This makes the choice incorrect for type 1 diabetes.
Choice C reason: Night sweats are not a primary manifestation of type 1 diabetes. They may occur in hypoglycemia but are not a hallmark symptom, unlike weight loss, making this choice incorrect.
Choice D reason: Weight loss in type 1 diabetes results from insulin deficiency, preventing glucose uptake, leading to fat and muscle breakdown for energy. This is a classic symptom, making this the correct choice.
Correct Answer is C
Explanation
Choice A reason: Loss of the thirst mechanism causes dehydration and hypernatremia, not hyponatremia, as water loss concentrates sodium. Hyponatremia requires excess water or sodium loss, making this choice incorrect for causing low sodium levels.
Choice B reason: Excessive aldosterone secretion causes sodium retention and hypernatremia, as it promotes sodium reabsorption in the kidneys. Hyponatremia involves sodium loss or dilution, not retention, making this choice incorrect for causing hyponatremia.
Choice C reason: Excessive sweating causes loss of sodium-containing fluids, leading to hyponatremia if water is replaced without electrolytes. This depletes serum sodium, disrupting electrolyte balance, making this the correct cause of hyponatremia in this context.
Choice D reason: Prolonged rapid, deep respirations cause respiratory alkalosis, not directly affecting sodium levels. Hyponatremia requires sodium loss or water excess, not respiratory changes, making this choice incorrect for causing low sodium levels.
