Options: Thermoregulation | Oxygen transport to peripheral tissues | Antibody synthesis | Blood pH stabilization

Correct Option: Oxygen transport to peripheral tissues (Index 1)

💡 Iron forms the essential heme core of hemoglobin, which binds and transports oxygen from lungs to systemic tissues.

Options: Ferrous Sulphate | Iron Fumarate | Ferrous Bisglycinate Chelate | Iron Carbonyl

Correct Option: Ferrous Bisglycinate Chelate (Index 2)

💡 Ferrous Bisglycinate consists of iron bound to two glycine amino acid molecules, maximizing absorption and preventing GI distress.

Options: 15 mg | 36 mg | 667 mcg | 300 mcg

Correct Option: 36 mg (Index 1)

💡 Each tablet delivers 36 mg of elemental iron in a non-irritating amino-acid chelated structure.

Options: Hemoglobin | Transferrin | Ferritin | Albumin

Correct Option: Ferritin (Index 2)

💡 Ferritin stores iron in a safe, water-soluble, non-toxic form, readily accessible when erythropoiesis is required.

Options: Fe(II) Ferrous | Fe(III) Ferric | Metallic Iron | Iron Oxide

Correct Option: Fe(III) Ferric (Index 1)

💡 Iron inside the ferritin shell is kept oxidized in the ferric Fe(III) state.

Options: 20% | 50% | 90% | 200%

Correct Option: 90% (Index 2)

💡 Chelation prevents premature precipitation in gut lumens, boosting oral absorption by up to 90% over inorganic iron salts.

Options: Maintaining iron in soluble reduced Fe(II) form and aiding mucosal transport | Preventing blood coagulation | Increasing urinary excretion | Inhibiting hepatic hepcidin

Correct Option: Maintaining iron in soluble reduced Fe(II) form and aiding mucosal transport (Index 0)

💡 Ascorbic acid acts as a reducing agent, converting insoluble ferric iron to soluble ferrous iron at mucosal membranes.

Options: Normal size | Larger than normal | Smaller than normal with lower hemoglobin saturation | Devoid of membrane lipids

Correct Option: Smaller than normal with lower hemoglobin saturation (Index 2)

💡 Iron deficiency impairs hemoglobin synthesis, resulting in microcytic (small) and hypochromic (pale) erythrocytes.

Options: Altering tablet color | Bypassing GI degradation, preventing constipation, nausea, and epigastric distress | Increasing physical weight | Decreasing production cost

Correct Option: Bypassing GI degradation, preventing constipation, nausea, and epigastric distress (Index 1)

💡 The double glycine covalent chelation shields iron from reacting with stomach acid and intestinal mucosa.

Options: Elemental Iron | Vitamin B6 | Folic Acid | Vitamin C

Correct Option: Folic Acid (Index 2)

💡 Folic Acid is crucial for DNA synthesis and preventing Neural Tube Defects (NTDs) like spina bifida.

Options: True | False

Correct Option: True (Index 0)

💡 True. Tight homeostatic buffer systems maintain systemic arterial pH within 7.35–7.45.

Options: True | False

Correct Option: False (Index 1)

💡 False. Platelets (thrombocytes) and coagulation factors form clots; white blood cells mediate immunity.

Options: True | False

Correct Option: True (Index 0)

💡 True. Multiple clinical trials confirm bisglycinate has superior mucosal transport and fewer adverse events.

Options: True | False

Correct Option: True (Index 0)

💡 True. These reticuloendothelial tissues house main iron storage depots.

Options: True | False

Correct Option: False (Index 1)

💡 False. Neonates have highest baseline hemoglobin (15–21 g/dL), which decreases during early infancy.

Options: True | False

Correct Option: True (Index 0)

💡 True. Vitamin B12 is essential alongside folic acid and iron for erythrocyte maturation.

Options: True | False

Correct Option: True (Index 0)

💡 True. Liver-derived hepcidin controls ferroportin channels on enterocytes and macrophages.

Options: True | False

Correct Option: True (Index 0)

💡 True. Deficiencies in nuclear maturation factors B12 or folate lead to large megaloblastic cells.

Options: True | False

Correct Option: False (Index 1)

💡 False. Plasma makes up ~55%, while cellular elements (RBCs, WBCs, platelets) constitute ~45%.

Options: True | False

Correct Option: True (Index 0)

💡 True. Optimizing hemoglobin levels enhances systemic oxygen delivery and aerobic performance.
