Which of the following can induce Raynaud's phenomenon?

beta-blockers
Pyridostigmine
Folate
Iron supplements

The correct answer is: beta-blockers

Raynaud's phenomenon is a condition that causes narrowing of small blood vessels, usually in the hands and feet, causing them to feel cold and numb. Beta-blockers are commonly used to treat high blood pressure and heart disease. However, they can also lead to Raynaud's phenomenon by constricting blood vessels and reducing blood flow. Pyridostigmine is a medication used to treat myasthenia gravis and does not have any known association with Raynaud's phenomenon. Folate is a B vitamin that is essential for the body's functions and has no known effect on this condition. Iron supplements are often used to treat iron-deficiency anemia and do not induce Raynaud's phenomenon. Therefore, A is the only option that can induce this condition.
