A patient tells the nurse that he's happy that his wife did not catch the same cold from which he has recently recovered. The nurse realizes that what most likely occurred in his wife?
 
  1. Helper T cells had a memory of a previous exposure to the same virus that caused the patient's illness.
  2. Suppressor T cells killed the virus.
  3. The virus was eliminated via phagocytosis by neutrophils.
  4. Cytokines were released.

Question 2

A patient sustains fractures to the ribs, both femurs, and one humerus. When planning care for this patient's immunologic status, what should the nurse include?
 
  1. Monitor complete blood count daily.
  2. Limit food rich in iron.
  3. Perform passive range of motion to unaffected extremities.
  4. Keep on bed rest.

Answer to Question 1

Correct Answer: 1

Helper T cells stimulate B cells to make antibodies to specific antigens. These cells then have a memory of exposure, which will lead to a quick response if another exposure occurs. In this scenario, the wife must have had a previous exposure to the same virus that caused the patient's cold, and because of this memory, the body immediately responded by eliminating the cold virus. Suppressor T cells stop the immune process and would not kill virus cells. Phagocytosis of the virus by neutrophils is an antibody-mediated response. This scenario describes a cell-mediated immune response. Cytokines are chemical messengers produced by cells to either increase the flow of white blood cells to a body area or coat an antigen to encourage phagocytosis.

Answer to Question 2

Correct Answer: 1

Bone marrow is soft organic tissue found in the hollow cavity of the long bones, particularly the femur and humerus, as well as the flat bones of the pelvis, ribs, and sternum. Bone marrow produces and stores hematopoietic stem cells, from which all cellular components of the blood are derived. Because the patient has fractured ribs, femurs, and one humerus, the nurse should monitor the patient's complete blood count daily. Food rich in iron should not be limited. Performing passive range of motion to the unaffected extremities or keeping the patient on bed rest will not improve the patient's immunologic status
