What should a coughing patient examine their sputum for?

• A. Consistency, color, amount, color change
• B. Smell and texture only
• C. Volume and temperature only
• D. Color and weight only

Answer: (A)

Observing sputum tells you a lot about what’s happening in the airways and how the patient is responding to treatment. The best practice is to note several features: how much sputum is produced (amount), what it looks like (color and consistency), and whether its appearance changes over time (color change). The amount helps you gauge severity and improvement with therapy. Color provides clues about the process—clear or white can fit viral or noninfectious causes, yellow to green often points to bacterial infection, and rust‑colored or pink-tinged sputum can indicate blood or edema and may signal a complication. Consistency shows how thick or thin the mucus is, which affects how easily it can be cleared from the airways. Watching for a change in color over time is key to detecting worsening infection or response to treatment.

Smell and texture alone don’t give the full diagnostic picture, and volume with temperature or color with weight miss important details you’d want to track. Documenting these aspects—amount, color, consistency, and color change—helps guide airway clearance strategies, treatment decisions, and when to escalate care.
