Why are erythropoiesis-stimulating agents (ESAs) prescribed for patients with chronic kidney disease?
 
  a. To protect the kidney from further hypoxic damage during anemia episodes
  b. To improve blood cell counts and reduce the need for blood transfusions
  c. To prevent vein thromboembolism during periods of dehydration
  d. To reduce the risk of uric acid precipitation and renal failure

Question 2

Why is it important to avoid killing off normal flora with antibacterial drugs?
 
  a. Normal flora can help provide protection against the development of pathogenic infections.
  b. Normal flora result in opportunistic infections while other bacteria result in pa-thogenic infections.
  c. When normal flora are not present, the immune system is suppressed, increasing the risk for infection.
  d. When normal flora are not present, the immune system is overactive, increasing the risk for autoimmune diseases.

Answer to Question 1

B
ESAs stimulate the bone marrow to produce more red blood cells. The person with chronic kid-ney disease has chronic anemia because the damaged kidney no longer produces natural eryt-hropoietin. The use of ESAs in patients with chronic kidney disease improves red blood cell counts and reduces anemia to such an extent that blood transfusions often are no longer needed.

Answer to Question 2

A
Normal flora are the nonpathogenic bacteria that are always present on skin, mucous membranes, and in the digestive tract. They provide protection by crowding out pathogenic organisms and preventing them from entering the body.
