The patient requests information on alternative treatments for her arthritis. The nurse provides the patient with information on which of the following supplements?

A. Nausea and vomiting: Nausea and vomiting can occur with epoetin alfa, but it's not the most common side effect.

B. Orthostatic hypotension: This is not a common side effect of epoetin alfa. Orthostatic hypotension is a decrease in blood pressure upon standing.

C. Hypertension: Epoetin alfa stimulates the production of red blood cells. When the red blood cell count increases too quickly, it can lead to increased blood pressure, which is the most common adverse effect.

D. Dizziness: Dizziness can occur with epoetin alfa, but it's less common than hypertension.

A. Fish oil: While fish oil has some evidence for reducing inflammation, the evidence for its effectiveness in treating arthritis is mixed.

B. DHEA: DHEA is a hormone and there is not enough evidence to support its use for arthritis.

C. Garlic and soy: While garlic and soy have some general health benefits, there is no strong evidence they are effective for treating arthritis.

D. Chondroitin and glucosamine: These supplements are the most studied option for arthritis and some studies have shown they may provide modest pain relief, although the evidence is not conclusive.
