Match the following endocrine disorders to the most relevant diagnostic test:
Cushing's Syndrome
Addison's Disease
Graves Disease
Diabetes Insipidus
Hashimoto's Thyroiditis
The Correct Answer is {"A":{"answers":"B"},"B":{"answers":"A"},"C":{"answers":"C"},"D":{"answers":"D"},"E":{"answers":"F"}}
Cushing’s Syndrome → Dexamethasone Suppression Test
- Cushing’s Syndrome results from excess cortisol. The dexamethasone suppression test evaluates whether cortisol production is appropriately suppressed by exogenous steroids.
Addison’s Disease → ACTH Stimulation Test
- Addison’s Disease involves adrenal insufficiency. The ACTH stimulation test checks if the adrenal glands can produce cortisol when stimulated.
Graves’ Disease → TSH Receptor Antibody Test
- Graves’ Disease is an autoimmune hyperthyroid condition where autoantibodies stimulate the thyroid. The TSH receptor antibody test detects these autoantibodies.
Diabetes Insipidus → Water Deprivation Test
- Diabetes Insipidus causes excessive urination due to ADH deficiency or resistance. The water deprivation test assesses the kidneys' ability to concentrate urine in response to dehydration.
Hashimoto’s Thyroiditis → Antithyroid Antibody Test
- Hashimoto’s Thyroiditis is an autoimmune hypothyroid disorder characterized by elevated antithyroid antibodies.

Correct Answer is D
Explanation
(A) Sodium: Thiazide diuretics can lower sodium, but hyponatremia does not directly affect digoxin toxicity.
(B) Magnesium: Magnesium is important for cardiac function but not as directly linked to digoxin toxicity as potassium.
(C) Calcium: Thiazides can cause hypercalcemia, but calcium does not significantly affect digoxin toxicity.
(D) Potassium: Thiazide diuretics (e.g., hydrochlorothiazide) cause potassium loss, which increases the risk of digoxin toxicity. Hypokalemia sensitizes the heart to digoxin’s effects, leading to arrhythmias.
Correct Answer is A
Explanation
(A) Include foods rich in potassium in the diet: Torsemide is a loop diuretic, which increases potassium excretion and may cause hypokalemia, requiring potassium supplementation.
(B) Increase calcium-rich foods: Torsemide primarily affects potassium, not calcium.
(C) Restrict fluid intake to 500 mL/day: Fluid restrictions may be necessary in severe heart failure, but 500 mL/day is too restrictive unless specifically indicated.
(D) Restrict foods rich in potassium in the diet: Torsemide causes potassium loss, not retention, so restricting potassium would worsen hypokalemia.
