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: A

Rationale: Isoflurane is not known to cause elevated lipid levels. Common effects of isoflurane include nausea, increased blood flow to the brain, and decreased respiratory function. Elevated lipid levels are not typically associated with the administration of isoflurane, making choice A the correct answer.

Correct Answer: D

Rationale: Lansoprazole is a proton pump inhibitor mainly used to treat conditions related to the stomach, such as gastritis, peptic ulcers, and Zollinger-Ellison syndrome. Thalamus hypertrophy is not a condition that Lansoprazole is indicated for; it is used for gastrointestinal issues and not neurological conditions.

Correct Answer: A

Rationale: Quinidine is classified as a class IA sodium channel blocker. Class IA antiarrhythmics, like quinidine, work by blocking sodium channels and delaying repolarization. Propafenone, mentioned in the original rationale, is actually a class IC antiarrhythmic agent, not a class IA sodium channel blocker.
