Correct Answer: A

Rationale: Insomnia is a common symptom of levothyroxine overdose due to excessive stimulation of the central nervous system. Levothyroxine is a thyroid hormone replacement medication, and an overdose can lead to hyperthyroidism symptoms, including insomnia. Constipation and drowsiness are not typically associated with levothyroxine overdose. Hypoactive deep-tendon reflexes are more indicative of hypothyroidism rather than an overdose of levothyroxine.

Correct Answer: D

Rationale: The correct answer is D. Methotrexate is not typically used to treat rheumatic fever, which is more commonly managed with antibiotics to eradicate the underlying infection. Methotrexate is commonly used in the treatment of conditions like sarcomas, leukemias, and ectopic pregnancies due to its anti-inflammatory and anti-cancer properties.

Correct Answer: C

Rationale: Nephritis is not commonly treated with Hydrochlorothiazide. Hydrochlorothiazide is primarily used for managing hypertension (HTN) and congestive heart failure (CHF) by reducing blood pressure and fluid retention. It is not a standard treatment for nephritis, which involves inflammation of the kidneys. Hypercalciuria, characterized by excessive calcium excretion in the urine, is not typically treated with Hydrochlorothiazide either.
