Magazine Chapter 8: Problem 50
What happens if folic acid is given to treat anemias without determining the underlying cause of the anemia? 1\. Erythropoiesis is inhibited. 2\. Excessive levels of folic acid may accumulate, causing toxicity. 3\. The symptoms of pernicious anemia may be masked, delaying treatment. 4\. Intrinsic factor is destroyed.
Short Answer
Expert verified
Option 3: The symptoms of pernicious anemia may be masked, delaying treatment.
Step by step solution
01
Identify the Correct Option
Begin by examining the list of potential outcomes given in the options. Consider their possible implications on health if folic acid is administered without diagnosing the specific type of anemia.
02
Understand the Role of Folic Acid
Folic acid is crucial for DNA synthesis and repair, particularly in fast-dividing cells like those in the bone marrow for producing red blood cells. Thus, it plays a key role in the process of erythropoiesis, rather than inhibiting it. This rules out Option 1.
03
Evaluate Toxicity of Folic Acid
Next, consider Option 2. While excessive levels of vitamins can sometimes lead to toxicity, folic acid is water-soluble, making toxicity unlikely unless consumed in extremely high doses. Therefore, Option 2 can be ruled out in typical clinical settings.
04
Consider Pernicious Anemia
Pernicious anemia is a type of vitamin B12 deficiency anemia, often caused by an inability to absorb the vitamin due to intrinsic factor deficiency. Administrating folic acid can correct the blood abnormalities caused by vitamin B12 deficiency but will not address the neurological damage. This can mask symptoms of pernicious anemia, therefore making Option 3 very likely.
05
Review the Role of Intrinsic Factor
Intrinsic factor, a protein produced by the stomach, is necessary for the absorption of vitamin B12. Administering folic acid does not impact the destruction or production of intrinsic factor, making Option 4 incorrect.
06
Select the Most Plausible Outcome
The analysis shows that administering folic acid without determining the specific cause of anemia can mask the symptoms of pernicious anemia, delaying correct diagnosis and treatment.

Key Concepts
These are the key concepts you need to understand to accurately answer the question.
Anemia Treatment
Anemia is a condition where a person has fewer red blood cells than normal or the quality of these cells is impaired.
Symptoms include fatigue, weakness, and pale skin. Treatment for anemia varies depending on the type and cause but often involves supplements, dietary changes, and sometimes medication.
- Iron-deficiency anemia: Usually treated with iron supplements and increased dietary iron.
- Vitamin-deficient anemia: May require folic acid or vitamin B12 supplements, particularly if a poor diet or absorption issues are the cause.
- Chronic disease anemia: Often involves treating the underlying disease impacting red blood cell production.
Folic Acid
Folic acid is a type of B vitamin crucial for making DNA and other genetic material. It is particularly important for women who are pregnant, as it helps prevent neural tube defects in the developing fetus.
In the body, folic acid aids in the creation of new red blood cells, essential for preventing types of anemia related to folate deficiency. However, it is essential not to administer folic acid blindly to treat anemia without knowing the underlying cause.
This is because while folic acid can correct certain effects of anemia, it does not resolve issues like vitamin B12 deficiency and can mask its symptoms, leading to a delay in proper treatment.
Pernicious Anemia
Pernicious anemia is a specific type of anemia resulting from vitamin B12 deficiency.
This occurs when the body cannot absorb vitamin B12 due to a lack of intrinsic factor, a protein produced by the stomach.
Although folic acid can help produce red blood cells, it does not address the neurological symptoms of B12 deficiency, such as numbness or balance issues.
Hence, if folic acid is administered without proper diagnosis, pernicious anemia might go undetected, potentially leading to complications due to untreated vitamin B12 deficiency.
Nursing Diagnosis
In nursing, a diagnosis is a critical step that involves identifying the nature of a patient's condition through assessment and analysis.
For anemia, a nursing diagnosis might involve:
- Assessing symptoms: This includes signs of fatigue, paleness, and weakness.
- Investigating causes: Gathering patient history and possible dietary deficiencies should be considered.
- Evaluating lab results: Important for identifying low levels of red blood cells or specific vitamin deficiencies.
Clinical Practice
Clinical practice involves applying medical and nursing knowledge to diagnose, treat, and care for patients effectively.
In the case of anemia, clinical practices help healthcare professionals ensure that each step taken is based on sound scientific evidence and individual patient needs.
This includes:
- Assessing symptoms and history to guide appropriate testing.
- Ensuring proper laboratory investigations are conducted to determine the cause of anemia.
- Formulating a treatment plan based on diagnosis, which might involve lifestyle changes, supplements, or other therapies.
