Questions on Clinical Manifestations of Vitamin B12 Deficiency Anemia:

Correct Answer is B

Explanation

Family history of pernicious anemia indicates a genetic predisposition, but it may not be the direct cause in this case. The gastrectomy is a more likely cause.

Correct Answer is C

Explanation

Higher energy levels are not a typical symptom of vitamin B12 deficiency anemia. Fatigue and weakness are more common symptoms of this condition.

Correct Answer is ["B","C","E"]

Explanation

This is a correct answer. Oval-shaped red blood cells (macro-ovalocytes) can be observed in the blood smear of individuals with vitamin B12 deficiency anemia. These abnormally shaped red blood cells are a characteristic finding.

Correct Answer is D

Explanation

Oral supplements may cause gastrointestinal distress. Rationale: This is the correct answer. Oral supplements of vitamin B12 may cause gastrointestinal distress, particularly in individuals with gastrointestinal issues. These supplements can be hard for some individuals to tolerate, leading to discomfort, gas, or other gastrointestinal symptoms. This is a significant consideration when choosing the route of administration for vitamin B12 treatment.

Correct Answer is B

Explanation

"Consume more citrus fruits for their vitamin B12 content." Rationale: This statement is incorrect. Citrus fruits are not a source of vitamin B12. They are known for their vitamin C content, but vitamin B12 is primarily found in animal-based foods.

Correct Answer is C

Explanation

Memory loss. Rationale: Memory loss is not a typical symptom of vitamin B12 deficiency anemia. Symptoms related to the nervous system, such as numbness and tingling, are more common neurological manifestations of the condition.

Correct Answer is D

Explanation

The correct answer is choice D. Neuropsychiatric symptoms such as confusion, irritability, and depression are indeed associated with vitamin B12 deficiency anemia.

Correct Answer is E

Explanation

The correct answer is choice E. The Schilling test measures the absorption of radioactive vitamin B12 in the urine and is specifically designed to differentiate between pernicious anemia (a type of B12 deficiency caused by impaired absorption) and other causes of malabsorption. This test helps identify the underlying cause of vitamin B12 deficiency.

Reticulocyte count measures the percentage of young, immature red blood cells in the blood and is not a specific test for confirming vitamin B12 deficiency anemia. While anemia is present in this case, it does not provide direct information about the underlying cause, which is best confirmed by meas

<p>The correct choice is D. When assessing a patient with suspected vitamin B12 deficiency anemia, it is crucial to examine the skin, mucous membranes, and eyes. Pallor (pale skin) and jaundice (yellowing of the skin and eyes) are common signs of anemia, and these can be detected through the inspect

Administering 2000 mcg of cyanocobalamin subcutaneously daily for a week, then monthly for life is not the preferred route for vitamin B12 supplementation in patients with pernicious anemia or severe malabsorption. Intramuscular injection is the preferred route as it ensures better absorption, and s

Foods high in iron and calcium, while important for overall health, are not the primary focus when addressing vitamin B12 deficiency anemia. Iron and calcium-rich foods are more relevant to iron-deficiency anemia and bone health, respectively. The primary focus for vitamin B12 deficiency anemia shou

Monitoring for signs of infection is a relevant action in the self-care plan for preventing recurrence of vitamin B12 deficiency anemia. Infections can lead to anemia by affecting the production of red blood cells. By monitoring for signs of infection and promptly seeking medical treatment if any si

Folate supplementation is not the primary treatment for vitamin B12 deficiency anemia. While folate (or folic acid) is essential for red blood cell production, it does not address the specific deficiency of vitamin B12. Vitamin B12 and folate are related but distinct nutrients, and vitamin B12 suppl

Measuring bone density is not a priority assessment for monitoring the effectiveness of treatment for vitamin B12 deficiency anemia. Bone density assessment is typically used to evaluate bone health and the risk of osteoporosis, which is not a primary concern in the context of vitamin B12 deficiency
