Hyperthyroidism can be treated by the following EXCEPT:

Correct Answer: A

Rationale: Carbimazole (choice A) and Propylthiouracil (choice D) treat hyperthyroidism by inhibiting thyroid hormone synthesis, Propranolol (choice C) manages symptoms. Carbamazepine (choice B), an anticonvulsant, is unrelated, making it the exception. This clarifies antithyroid therapy.

Correct Answer: B

Rationale: Aripiprazole is an antipsychotic medication that is commonly used to treat symptoms of Tourette syndrome, which includes tics like head jerking, blinking, and grimacing. Fluoxetine, clonazepam, naltrexone, and imipramine are not typically used for treating tics associated with Tourette syndrome.

Correct Answer: B

Rationale: The symptoms described in the scenario, such as elevated mood, rapid speech, muscle twitching, and dilated pupils, are consistent with the effects of marijuana use. Increased heart rate is a common physiological response to smoking marijuana due to the drug's impact on the cardiovascular system. Additionally, euphoria and uncontrollable laughter are typical psychological effects of marijuana use, further supporting the choice of increased heart rate as the correct answer.

Correct Answer: B

Rationale: These drugs can increase heart rate (tachycardia) through various mechanisms.

Correct Answer: D

Rationale: Hydromorphone is more potent than morphine because it requires a lower dose (smaller ED50) to produce the same analgesic effect.
