Which of the following is a risk factor for fluid volume deficit (FVD)?

Explanation:
Fever increases insensible fluid losses, making it a risk factor for fluid volume deficit. When body temperature rises, sweating and a faster breathing rate both boost fluid loss. If fluid intake doesn’t keep pace—often worsened by malaise or poor oral intake during illness—the total body water declines, supporting dehydration. Adequate hydration helps prevent FVD, and while regular exercise or high sodium intake can influence fluid balance, they are not as direct or consistent predictors of FVD as fever, which markedly elevates fluid losses.
