The nurse is teaching a class on how red blood cell formation is regulated by the body to a group of clients who have AIDS. The nurse evaluates that learning has occurred when the clients make which statements?

Question

1. "Red blood cell formation is regulated through chemicals called colony-stimulating factors that come from white blood cells."
2. "Red blood cell formation is regulated through messages from the hormone, secretin, which is located in the kidney."
3. "Red blood cell formation is regulated through specific liver enzymes and a process called hemochromatosis."
4. "Red blood cell formation is regulated through messages from the hormone erythropoietin."

Answer 1

4
Rationale 1: Colony-stimulating factors affect white blood cell production.
Rationale 2: Secretin stimulates the pancreas to release a fluid that neutralizes stomach acid and aids in digestion; it has nothing to do with red blood cell formation.
Rationale 3: Hemochromatosis refers to excess iron accumulation in the body, not to red blood cell formation.
Rationale 4: Regulation of hematopoiesis occurs through messages from hormones such as erythropoietin.
Global Rationale: Regulation of hematopoiesis occurs through messages from hormones such as erythropoietin. Colony-stimulating factors affect white blood cell production. Secretin stimulates the pancreas to release a fluid that neutralizes stomach acid and aids in digestion; it has nothing to do with red blood cell formation. Hemochromatosis refers to excess iron accumulation in the body, not to red blood cell formation.
