Question

RBC counting is low in anemia and?
A) Typhoid
B) Leukemia
C) Influenza
D) Myxoedema

Answer 1

Hint: Erythropoiesis is the name given to the production of RBCs (erythrocytes), and is dependent on many complex factors. The major function of RBCs is the transport of delivery of oxygen. A decrease in RBC mass and oxygen-carrying capacity is known as anemia.

Complete step-by-step answer:
In leukemia the number of White blood cells ( granulocytes) increases but the number of RBCs decreases. But otherwise, leukemia is caused by the human T-cell lymphotropic virus. Its symptoms include bleeding, nosebleed, red spots on the skin, and swollen lymph nodes. It is transmitted through transfusion of infected blood, sexually transmitted by mosquitoes.
Typhoid is caused by salmonella typhi. Its symptoms include fever, headache, abdominal pain, anorexia, and malaise. It is transmitted through ingestion of food or water contaminated by feces of an infected human or animal. It can be cured by ceftriaxone, trimethoprim-sulfamethoxazole, or ampicillin.
Myxoedema is caused due to long-standing hypothyroidism that is not diagnosed and is usually precipitated by a systemic illness. It mostly causes chronic autoimmune thyroiditis. Its symptoms include feeling cold, low body temperature, swelling of the body, especially face, tongue, and lower legs, and difficulty in breathing.
Influenza is a viral disease that can be deadly, especially in high-risk groups. It attacks the nose, lungs, and throat. Persons with low immunity or weaker immune system are at high risk. Its symptoms include fever, chills, muscle aches, cough, congestion, runny nose, headaches, and fatigue.

Therefore the correct answer is option B, leukemia.

Note: Hemoglobin is the molecule in the RBCs that is responsible for binding the oxygen that red cells carry. Therefore, the measurement of Hb provides an accurate, reproducible means of detecting anemia. The bone marrow reveals red cell precursors that are megaloblastic, that is, large with fine, sparse nuclear chromatin.
