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.

Chronic necrotizing aspergillosis has a slowly progressive process that, unlike invasive aspergillosis, does not spread to other organ systems or the blood vessels. It most often affects middle-aged and elderly individuals, spreading to surrounding tissue in the lungs. The disease often does not respond to conventionally successful treatments, and requires individualized therapies in order to keep it from becoming life-threatening.

However, without proper precautions, an individual may contract the disease repeatedly. In fact, most people develop trichomoniasis again within three months of their last treatment.

People who have myopia, or nearsightedness, are not able to see objects at a distance but only up close. It occurs when the cornea is either curved too steeply, the eye is too long, or both. This condition is progressive and worsens with time. More than 100 million people in the United States are nearsighted, but only 20% of those are born with the condition. Diet, eye exercise, drug therapy, and corrective lenses can all help manage nearsightedness.
