The nurse is providing education to the female client taking methotrexate for Rheumatoid Arthritis. What would the nurse tell this client to avoid while taking methotrexate?

Choice A rationale Aerobic exercise, when tolerated, is generally encouraged for clients with rheumatoid arthritis (RA) to maintain joint mobility, muscle strength, and overall cardiovascular health. There is no contraindication for aerobic exercise specifically related to the pharmacokinetics or adverse effects of methotrexate, provided the client's RA is not acutely flaring. Choice B rationale Methotrexate is metabolized in the liver and carries a significant risk of hepatotoxicity, especially with prolonged use. Concomitant alcohol consumption markedly increases this risk of liver damage (cirrhosis or fibrosis) due to the synergistic hepatotoxic effect of the two substances, therefore alcohol should be completely avoided by clients taking this medication. Choice C rationale Methotrexate is classified as a powerful teratogen, meaning it can cause severe and profound birth defects, including skeletal, cardiac, and cranial abnormalities, in an exposed fetus. It can also cause spontaneous abortion. Therefore, pregnancy must be strictly avoided by female clients taking methotrexate, and reliable contraception is mandatory. Choice D rationale While smoking is generally discouraged for all clients, particularly those with inflammatory conditions like RA, due to its negative effects on joint health and overall cardiovascular risk, there is no direct, specific drug-drug or drug-lifestyle interaction between nicotine/smoking and methotrexate that is considered a major contraindication in the same vein as pregnancy or alcohol use. Choice E rationale Both alcohol consumption and pregnancy are absolute contraindications for a client taking methotrexate. Alcohol significantly increases the risk of severe hepatotoxicity (liver damage), and methotrexate is a known, potent teratogen that causes severe birth defects and is contraindicated during pregnancy. Clients must be strictly advised to avoid both while on this therapy.
