Which of the following patients has an absolute neutrophil count that is critically low and that the standard of care would recommend they be placed on neutropenic precautions?
 
  A)
  A patient on long-term steroids for rheumatoid arthritis with WBC of 7000
  B)
  A 37-year-old patient with leukemia being treated with chemotherapy with ANC of 400
  C)
  A 65-year-old prostate cancer patient receiving radiation therapy with neutrophil count of 2000
  D)
  A 75-year-old renal failure patient receiving Epogen for anemia with hemoglobin level of 9.7.

Question 2

A 44-year-old male hospital client with a diagnosis of end-stage acquired immunodeficiency syndrome (AIDS) has been placed on neutropenic precautions that limit his interaction with visitors, staff, and other clients.
 
  What is the underlying rationale for these precautions?
  A)
  His antibody-mediated immunity is compromised by his low production of neutrophils.
  B)
  Neutropenia limits the ability of his CD4 helper cells to present antigens.
  C)
  Insufficient levels of neutrophils make him particularly susceptible to infections.
  D)
  Cyclic neutropenia limits his body's ability to fight various infections.

Answer to Question 1

Ans:
B

Feedback:

Neutrophils constitute the majority of blood leukocytes and play a critical role in host defense mechanisms against infections. The ANC is supposed to be 1000/ L, and if the ANC is less than 500 cells/mm3, the person is generally put on neutropenic precautions in the hospital to protect him or her from the environment. A patient on long-term steroids for rheumatoid arthritis with WBC of 7000 has a normal WBC count; a prostate cancer patient receiving radiation therapy with neutrophil count of 2000 has a normal neutrophil count; a renal failure patient receiving Epogen for anemia with hemoglobin level of 9.7 is associated with RBCs and not neutrophils.

Answer to Question 2

Ans:
C

Feedback:

A decrease in the number of neutrophils places an individual at risk for infection. Neutrophils are not directly involved in the antibody-mediated immune process, and his neutropenia is infection related, not cyclic.
