The health care providers and nurses caring for a group of clients with cancer have instituted a strict nutritional program with the goal of stimulating the clients' natural killer cells. How do these cells work?
 
  Standard Text: Select all that apply.
  1. They phagocytize cancer cells.
  2. The cells secrete chemical toxins that kill cancer cells.
  3. They help to enhance inflammation.
  4. They protect noncancerous cells from attack by viruses that cause cancer.
  5. They modulate the adaptive immune response.

Question 2

A client who is not immunized against influenza has been exposed to the antigen that causes it. The nurse is aware that peak production of antibodies against this antigen will take about _____ days.
 
  Fill in the blank with the appropriate word.

Answer to Question 1

Correct Answer: 2,3,5
Rationale 1: Natural killer cells are not phagocytic.
Rationale 2: Natural killer cells do secrete toxins that kill cancer cells.
Rationale 3: Natural killer cells secrete chemicals that enhance inflammation.
Rationale 4: Interferons protect cells from viruses.
Rationale 5: Natural killer cells modulate the adaptive immune response.
Global Rationale: Cancer cells or virus-infected cells attract a different type of innate cellular response: natural killer (NK) cells. Found in most lymphoid organs, NK cells are not phagocytic, but they do release toxins that kill cancer cells or virus-infected cells. NK cells also secrete chemicals that enhance inflammation and modulate the adaptive immune response. NK cells do not phagocytize cancer cells or protect noncancerous cells from attack.

Answer to Question 2

Correct Answer: 10
Rationale: In a client who is not immunized and has not been exposed to the antigen before, peak production of antibodies takes about 10 days.
Global Rationale: Circulating through body fluids are antibodies, also known as immunoglobulins (Ig), which physically interact with antigens to neutralize or mark them for destruction by other cells of the immune response. The activation of complement, with subsequent inflammation and enhanced phagocytosis, is a major defense mechanism resulting from the formation of antigenantibody complexes. Peak production of antibodies occurs about 10 days after an initial antigen challenge such as an immunization.
