A nurse is caring for a patient with rheumatoid arthritis. The patient is prescribed hydroxychloroquine to slow the progression of the disease. Which of the following laboratory results should the nurse monitor for this patient?

Choice A is incorrect: Caffeine can worsen sleep disturbances, a common symptom of fibromyalgia.
Choice B is incorrect: While duloxetine is a medication used to manage fibromyalgia symptoms, taking it at a specific time for increased energy is not directly related to understanding the disease itself.
Choice C is incorrect: Fibromyalgia is a chronic condition with no cure. Chemotherapy is not indicated for its treatment.

Choice D is correct: Low-impact aerobics like walking, swimming, or yoga are recommended non-pharmacological interventions for fibromyalgia. They can improve cardiovascular health, flexibility, and pain management.
Additional notes:
Other non-pharmacological management strategies for fibromyalgia include stress management techniques, cognitive behavioral therapy, and adequate sleep hygiene.
Early and comprehensive management of fibromyalgia can significantly improve quality of life.

Choice A rationale:
Lymph nodes are small, bean-shaped structures that play a crucial role in the immune system. They filter lymph fluid, which carries white blood cells and other immune cells throughout the body.
When the body is fighting an infection or other immune challenge, lymph nodes often swell and become tender. This is because they are actively working to filter out pathogens and activate immune cells.
Palpation of the lymph nodes can provide valuable information about the patient's immune function. The nurse can assess for enlargement, tenderness, and mobility of the lymph nodes.
Lymph node assessment is a non-invasive, painless procedure that can be performed quickly and easily.
Choice B rationale:
Auscultation of the apical heart rate is important for assessing cardiovascular function, but it does not directly assess immune function.
While heart rate can be indirectly affected by certain immune conditions (e.g., fever), it is not a primary indicator of immune system activity.
Choice C rationale:
Palpation of the liver can provide information about liver size and consistency, but it does not directly assess immune function.
The liver plays a role in immune function by producing proteins that help fight infection, but its size and consistency do not necessarily reflect its immune activity.
Choice D rationale:
Percussion of the abdomen can be used to assess the size and location of abdominal organs, but it does not directly assess immune function.
While certain immune conditions may involve abdominal organs (e.g., splenomegaly), percussion is not a primary method for assessing immune function.
