A client with rheumatoid arthritis (RA) is prescribed methotrexate, a disease-modifying antirheumatic drug (DMARD). What should the nurse include in the teaching plan for this client?

The client should be advised to avoid drinking alcohol while taking methotrexate, as this can increase the risk of hepatotoxicity and liver damage. Methotrexate is metabolized by the liver and can cause elevated liver enzymes and inflammation. The client should also have regular liver function tests while taking this medication.

Incorrect options:

A) "You should take this medication with food or milk to prevent stomach upset." - This is not a correct statement, as methotrexate should be taken on an empty stomach, at least one hour before or two hours after meals, to enhance absorption and effectiveness.

C) "You should monitor your blood pressure regularly while taking this medication." - This is not a relevant statement, as methotrexate does not affect blood pressure. However, the client should monitor their blood counts regularly while taking this medication, as methotrexate can cause bone marrow suppression and anemia.

D) "You should take this medication every day for optimal results." - This is not a correct statement, as methotrexate is usually taken once a week for RA. Taking it more frequently can increase the risk of adverse effects and toxicity.

Cyanosis of the lips and nail beds is a sign of hypoxemia, which indicates inadequate oxygenation of the blood. This is a potential complication of COPD, as the disease causes airflow obstruction and impaired gas exchange. Cyanosis requires immediate intervention to improve oxygen delivery and prevent tissue damage.

Incorrect options:

A) Barrel-shaped chest - This is a common finding in clients with COPD, as the disease causes hyperinflation of the lungs and increased anteroposterior diameter of the chest. It is not a sign of a complication, but rather a chronic adaptation to the disease.

B) Clubbing of the fingers - This is a possible finding in clients with COPD, as the disease causes chronic hypoxia and stimulation of vascular endothelial growth factor, leading to thickening and widening of the distal phalanges. It is not a sign of a complication, but rather a long-term effect of the disease.

D) Wheezes on auscultation - This is an expected finding in clients with COPD, as the disease causes narrowing of the airways and increased airway resistance. It is not a sign of a complication, but rather a characteristic manifestation of the disease.
