Answer to Question 1

ANS: A, B, C
Sudden onset of muscular weakness, inability to swallow or speak, and sudden respiratory dis-tress are all symptoms characteristic of myasthenic crisis, whereas the other symptoms are char-acteristic of cholinergic crisis.

Answer to Question 2

ANS: C
The use of dopaminergic drugs, such as levodopa, is contraindicated in patients with nar-row-angle glaucoma, blood dyscrasias, uncontrolled hypertension, who are concurrently using monoamine oxidase inhibitors (MAOIs), or who have hypersensitivity to the drug or its ingredi-ents. Levodopa should also not be used in patients with history of malignant melanoma.
