Which physiological response is often associated with surgery-related stress?

  1. Bronchial constriction

  2. Decreased cortisol levels

  3. Peripheral vasodilation

  4. Sodium and water retention

The correct answer is: Sodium and water retention

Surgery-related stress often triggers the physiological response of sodium and water retention. This response is primarily mediated by the increased release of antidiuretic hormone (ADH) and aldosterone, which are hormones that act to retain sodium and water in the body under stressful conditions. This mechanism helps maintain blood pressure and fluid balance during times of increased stress, such as surgery. The other options are not typically associated with surgery-related stress.
