Which of the following drugs most likely caused the patient's death?

Correct Answer: D

Rationale: The patient's signs and symptoms, such as mydriasis, tonic-clonic seizure, shallow respiration, and cardiovascular collapse leading to death, are consistent with LSD intoxication. LSD is known to cause agitation, altered mental status, and severe physiological effects, making it the most likely cause of the patient's death.

Correct Answer: A

Rationale: The patient reported heavy drowsiness as a side effect of the current medication. Amitriptyline is known to cause sedation and drowsiness, making it the most likely drug to have been prescribed in this case.

Correct Answer: A

Rationale: DES, a synthetic estrogen, causes deep vein thrombosis (choice A), feminization of male offspring (choice B), and miscarriages (choice C) in pregnancy, linked to historical congenital anomalies (e.g., vaginal adenocarcinoma). Virilization of female offspring (choice D) isn't reported; DES mimics estrogen, not androgens. This exception highlights its teratogenic risks, banning its use in pregnancy.

Correct Answer: B

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

Correct Answer: D

Rationale: All of these are corticosteroids commonly used for allergic rhinitis due to their anti-inflammatory effects.
