Which of the following hormones is secreted by the thyroid gland?
Renin
Brain natriuretic peptide (BNP)
Erythropoietin
Calcitonin
The Correct Answer is D
Choice A reason: Renin, from the kidneys, regulates blood pressure via angiotensin, not a thyroid product, unrelated to its metabolic or calcium functions.
Choice B reason: BNP, secreted by the heart, reduces volume overload in heart failure, not a thyroid hormone, distinct from its endocrine role.
Choice C reason: Erythropoietin, from kidneys, stimulates red blood cell production, not produced by the thyroid, which focuses on metabolism and calcium.
Choice D reason: Calcitonin, from thyroid parafollicular cells, lowers blood calcium by inhibiting bone resorption, a key thyroid hormone alongside T3/T4.

Explanation
Choice A reason: Anuria in hemodialysis is expected due to renal failure; it’s not acute unless accompanied by distress, less urgent than chest pain’s potential severity.
Choice B reason: Itching in cirrhosis from bile salts is uncomfortable but not life-threatening, ranking below chest pain, which could indicate critical cardiac or pulmonary issues.
Choice C reason: Pain when walking in PAD (claudication) is chronic and stable, not an immediate threat compared to chest pain, which requires urgent evaluation.
Choice D reason: Chest pain in lupus may signal pericarditis or pleuritis, potentially life-threatening complications, prioritizing assessment for rapid intervention over stable conditions.
