A goiter is characterized by which of the following?

Fever of 103 degrees

An enlarged thyroid

Fibrotic tissue in the arterioles

Deposits of glycosaminoglycans in the skin

Answer and Explanation

The Correct Answer is B

Choice A reason: Fever of 103°F may occur in thyroid storm, not goiter, which is simply thyroid enlargement without systemic hypermetabolism or infection necessarily.

Choice B reason: Goiter is defined by thyroid gland enlargement, often from iodine deficiency or hyperplasia, palpable as a neck mass, the core characteristic here.

Choice C reason: Fibrotic tissue in arterioles relates to vascular diseases, not goiter, which involves thyroid tissue growth, not arterial structural changes.

Choice D reason: Glycosaminoglycan deposits occur in myxedema (hypothyroidism), not goiter, which is enlargement alone, not skin or connective tissue alteration.

Correct Answer is A

Explanation

Choice A reason: Hypothyroidism slows metabolism due to low thyroid hormone, reducing calorie burning and causing weight gain from fat accumulation and fluid retention in tissues.

Choice B reason: Diaphoresis (sweating) occurs in hyperthyroidism from excess metabolism raising body heat. Hypothyroidism causes dry skin and cold intolerance, not sweating.

Choice C reason: Exophthalmos, bulging eyes, results from Graves’ disease in hyperthyroidism due to orbital inflammation. Hypothyroidism doesn’t affect eye protrusion, making this unlikely.

Choice D reason: Palpitations stem from hyperthyroidism’s increased heart rate via excess thyroid hormone. Hypothyroidism slows heart rate, leading to bradycardia, not palpitations.

A. Chest pain while at rest B. A complete occlusion of the coronary artery C. Chest pain upon exertion that resolves with rest D. A partial occlusion of the coronary artery

Correct Answer is A

Explanation

Choice A reason: NSTEMI causes chest pain at rest due to reduced blood flow from partial occlusion, unlike stable angina, reflecting demand-supply mismatch without full blockage.

Choice B reason: Complete occlusion causes ST-elevation MI (STEMI), not NSTEMI, which involves partial blockage, leading to subendocardial ischemia without full transmural infarction.

Choice C reason: Chest pain on exertion resolving with rest describes stable angina, not NSTEMI, which occurs unpredictably, often at rest, due to unstable plaque rupture.

Choice D reason: NSTEMI results from partial coronary occlusion, causing ischemia without ST elevation, detectable by troponin rise, distinguishing it from STEMI’s complete blockage.
