What does prognosis mean?

• A. The electrical activity of the heart
• B. The forecast of the likely course and outcome of a disease
• C. The rate of blood flow
• D. The effect of medication on pain

Answer: (B)

Prognosis is the forecast of the likely course and outcome of a disease. It describes what may happen in the future—the chances of recovery, progression, or complications, and the expected duration or end result. This helps clinicians plan treatment and discuss realistic expectations with patients. The other options relate to current measurements or effects—electrical activity of the heart refers to heart rhythm, the rate of blood flow to circulation, and the effect of medication on pain concerns symptom relief rather than future outcomes.
