Answer to Question 1

D
Variant angina is caused by coronary artery spasm, which reduces the oxygen supply to the heart. Beta blockers are not effective in variant angina but are useful with stable angina. Medications may be given to prevent anginal attacks in both types of angina. Vasodilators are used in variant angina to relieve coronary artery spasm and increase the oxygen supply to the heart.

Answer to Question 2

C
Botulinum antitoxin contains neutralizing antibodies and can minimize further nerve damage, but cannot reverse damage that has already set in. It is not an antidote to the toxin. It does not restore strength in weakened muscles.
