Final answer:
In pernicious anemia, Vitamin B12 absorption is compromised hence its level should be carefully monitored. This condition can result from several factors including certain diseases, surgical procedures, and dietary habits. Sufficient B12 is critical for the production of normal red blood cells.
Step-by-step explanation:
When caring for a client with pernicious anemia, a nurse should closely monitor the patient's Vitamin B12 level. Pernicious anemia is caused by the body's inability to effectively absorb Vitamin B12 which is essential for the production of red blood cells. Therefore, the effectiveness of a treatment for this type of anemia can be evaluated by monitoring the increase in the patient's Vitamin B12 level.
Poor absorption of Vitamin B12 can result from various conditions such as Crohn's disease, surgical removal of a section of the stomach or intestines, intestinal parasites, and AIDS. It might also occur in those following a vegetarian or vegan diet due to the lack of meat or a viable alternate source for vitamin B12. Lack of sufficient Vitamin B12 can lead to production of megaloblastic red blood cells, which are larger and fewer than normal, leading to megaloblastic anemia.
