A patient asks the nurse about free radicals and how they contribute to illness. How should the nurse respond?
1. "Free radicals are cells also known as natural killer cells."
2. "Free radicals are bad substances that clog the liver so it cannot get rid of body toxins."
3. "Free radicals are substances that develop when we don't breathe deeply enough."
4. "Free radicals are produced naturally in cells but can be harmful if their balance in the body is not maintained."

Rationale 1: Free radicals are not the same as natural killer cells.
Rationale 2: Not all free radicals are injurious to the body. The liver is not the only organ affected by free radicals.
Rationale 3: Shallow breathing is not the etiology of free radicals.
Rationale 4: Free radicals are produced in cells either as a by-product of metabolism or deliberately, as in phagocytosis. They have a useful function under controlled conditions but can damage cells if left uncontrolled.
