Answer to Question 1

B
With higher doses of marijuana, euphoria may be displaced by intense anxiety. Chronic use may cause irreversible brain changes. Euphoria, sedation, and hallucinations can all occur with mari-juana use. Ingesting marijuana causes prolonged effects.

Answer to Question 2

D
Propylthiouracil is used for patients experiencing thyroid storm, and this patient is showing signs of that condition. Levothyroxine is given IV for hypothyroidism. 131I is used in patients over age 30 who have not responded to other therapies. Methimazole is used long term to treat hyperthy-roidism, but PTU is more useful for emergency treatment.
