The nurse understands that the client is responding favorably to a prescription for colchicine when there is a decrease in which sign/symptom?

Appeared in: NORCET 5 Prelims - Sept 2023 (Shift-2)

Explanation

Colchicine is an anti-inflammatory agent specifically used to treat acute gouty arthritis.
The primary pathology in an acute gout attack is severe inflammation within a joint, caused by the body's reaction to urate crystals.
Colchicine works by inhibiting the migration of inflammatory cells (leukocytes) into the joint, thereby interrupting the inflammatory cascade.
Therefore, a favorable response and the intended therapeutic effect of the drug is a noticeable decrease in joint inflammation, which includes reduced pain, swelling, redness, and tenderness.

Option A: Headaches are a potential adverse effect or side effect of colchicine, not a sign of a favorable therapeutic response.
Option C: Colchicine's mechanism of action does not involve the regulation of glucose metabolism. Its effects are specific to the inflammatory pathway in gout.
Option D: Colchicine has no direct effect on lipid metabolism or serum triglyceride levels. Its therapeutic action is confined to inflammation.

Clinical Relevance

Nursing practice connection: Use the key finding related to Therapeutic Effect of Colchicine to guide bedside assessment, documentation, and the next nursing action.
A key nursing responsibility is to assess for both the therapeutic effects (decreased joint inflammation) and adverse effects of colchicine.
The onset of gastrointestinal symptoms (nausea, vomiting, diarrhea) is a critical sign of colchicine toxicity and requires immediate reporting, as the medication may need to be stopped.
Patient education should emphasize taking the medication exactly as prescribed for an acute attack and reporting any GI distress immediately.

How to Approach the Question

First, identify the drug mentioned in the stem: Colchicine.
Recall or determine the primary indication for this drug. Colchicine is a classic medication for acute gout.
Think about the primary signs and symptoms of the condition it treats. Acute gout causes severe joint inflammation.
Connect the drug's action to the condition's symptoms. An effective anti-gout medication for an acute attack should reduce the inflammation.
Evaluate the options based on this connection. A decrease in 'joint inflammation' directly reflects the drug's intended therapeutic effect.
Rule out other options by considering if they are side effects (like headaches) or unrelated physiological parameters (like glucose or triglycerides).
