Rationale: Midazolam is a benzodiazepine commonly used for its sedative, anxiolytic, and amnestic effects. While dizziness can be a side effect of Midazolam, it is not a primary or common effect. Therefore, the correct answer is D, as it deviates from the typical effects associated with Midazolam.

Correct Answer: B

Rationale: Atenolol, a beta-blocker, is not typically associated with tachycardia. Instead, drug toxicity of Atenolol is more commonly linked to bradycardia due to its beta-blocking effects on the heart's electrical conduction system. Symptoms of Atenolol toxicity may include heart failure (CHF), AV block, and a sedative appearance, but not tachycardia.

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.
