1. What is levothyroxine's pharmacologic classification?

A. Thyroid Preparations
B. Metabolic Inhibitors
C. Analgesic
D. Loop Diuretic

Correct answer: A

Rationale: Levothyroxine is classified as a thyroid preparation because it is a synthetic form of the thyroid hormone thyroxine. It is primarily used to treat hypothyroidism by supplementing or replacing the natural thyroid hormones in the body, helping to regulate metabolism and energy levels. Choice B, Metabolic Inhibitors, is incorrect because levothyroxine does not inhibit metabolism but rather helps regulate it. Choice C, Analgesic, is incorrect as levothyroxine is not used for pain relief but for thyroid hormone replacement therapy. Choice D, Loop Diuretic, is also incorrect as loop diuretics are medications that act on the kidneys to increase urine production and are not related to thyroid hormone replacement therapy.
