Study Notes
- The radioactive iodine uptake (RAIU) test differentiates between the causes of hyperthyroidism.
- Autoimmune destruction of the adrenal cortex is the most common cause of primary adrenocortical insufficiency (Addison’s disease) in industrialized nations.
- A patient with Cushing’s syndrome is most likely to have hypokalemia and hypernatremia.
- Hypothyroidism is most commonly caused by iodine deficiency worldwide, but in developed countries, it is most commonly due to atrophy of the thyroid gland.
- Patients with Cushing’s syndrome often present with truncal obesity but have thin extremities due to protein catabolism leading to muscle wasting in the extremities while fat accumulates centrally.
- Aldosterone is primarily responsible for sodium and water retention in the body.
- A key characteristic of hyperthyroidism is exophthalmos and tachycardia.
- An electrolyte imbalance commonly seen in Addison’s disease is hyponatremia and hyperkalemia.
- A major risk factor for developing Cushing’s syndrome is long-term corticosteroid therapy.
- The primary goal of treatment for Cushing’s syndrome is normalizing hormone secretion by addressing the underlying cause.
- A potential complication of untreated hypothyroidism is myxedema coma.
- The ACTH stimulation test is used to confirm the diagnosis of Addison’s disease.
- Providing corticosteroid replacement therapy is crucial for a patient experiencing an Addisonian crisis.
- A common clinical feature of Cushing’s syndrome is moon face and truncal obesity.
- A dietary recommendation appropriate for a patient with hyperthyroidism is a high-calorie, high-protein diet.
- Radioactive iodine therapy for hyperthyroidism works by destroying thyroid tissue to reduce hormone secretion.
- The primary treatment for a patient with myxedema coma is IV levothyroxine and supportive care.
- A symptom expected in a patient with untreated hypothyroidism is fatigue and weight gain.
- Graves’ disease is caused by an autoimmune process leading to excessive thyroid hormone production.
- Administering thyroid hormone replacement therapy is most important for a patient with hypothyroidism.
- Increased secretion of parathyroid hormone is responsible for hyperparathyroidism.
- Pituitary gland dysfunction is the most common cause of secondary hypothyroidism.
- Hyperpigmentation is a distinguishing feature of Addison’s disease that is not typically seen in secondary adrenal insufficiency.
- A common treatment for a patient with hypoparathyroidism is calcium and vitamin D supplementation.
- A symptom that suggests a patient with hyperthyroidism is experiencing thyrotoxic crisis (thyroid storm) is severe tachycardia and hyperthermia.
