A nurse is educating a client about the etiology of iron-deficiency anemia.
Which statement by the nurse is accurate regarding iron absorption?
"Iron absorption can be impaired by consuming green leafy vegetables.”
"Inadequate iron intake is usually caused by chronic diseases.”
"Iron is primarily obtained from recycling old red blood cells.”
"Excessive iron loss can occur due to pregnancy and lactation.”
The Correct Answer is C
Choice A rationale:
The nurse's statement, "Iron absorption can be impaired by consuming green leafy vegetables," is not accurate.
Green leafy vegetables contain non-heme iron, which is less readily absorbed than heme iron found in animal products.
However, they do not impair iron absorption.
Choice B rationale:
The nurse's statement, "Inadequate iron intake is usually caused by chronic diseases," is not accurate.
Inadequate iron intake is typically caused by dietary factors, such as a lack of iron-rich foods in the diet.
Chronic diseases can lead to anemia, but they do so by affecting the body's utilization of iron, not by causing inadequate intake.
Choice D rationale:
The nurse's statement, "Excessive iron loss can occur due to pregnancy and lactation," is partially accurate.
Pregnancy and lactation can lead to increased iron requirements, but they do not directly cause excessive iron loss.
Iron loss through menstruation is a more common cause of iron deficiency in women.

Correct Answer is ["A","D"]
Explanation
Choice A rationale:
Microcytic anemia is characterized by red blood cells (RBCs) that are smaller than normal.
This can occur in conditions like iron-deficiency anemia and thalassemia, where there is impaired hemoglobin production or insufficient iron for RBC formation.
Choice B rationale:
Normocytic anemia is characterized by RBCs that are of normal size.
This can occur in various conditions, including chronic diseases like chronic kidney disease and some types of anemia of chronic inflammation.
Choice C rationale:
Macrocytic anemia is characterized by RBCs that are larger than normal.
This can be seen in conditions like megaloblastic anemia, which is often caused by vitamin B12 or folate deficiency.
Choice D rationale:
Anisocytosis refers to a condition where RBCs are of unequal sizes.
While it is not a specific type of anemia, anisocytosis can be seen in various types of anemia, including iron-deficiency anemia, as RBCs may vary in size due to different stages of development.
Choice E rationale:
Poikilocytosis refers to a condition where RBCs have abnormal shapes.
Like anisocytosis, poikilocytosis is not a specific type of anemia but can be observed in various anemias, including sickle cell anemia, where RBCs take on a characteristic crescent shape.
Correct Answer is ["A","B"]
Explanation
Choice A rationale:
"My tongue has been inflamed lately." Inflammation of the tongue, a condition known as glossitis, can be a clinical manifestation of iron-deficiency anemia.
When the body lacks sufficient iron, it may not produce enough hemoglobin, which can lead to changes in the appearance and texture of the tongue.
Glossitis can cause the tongue to become red, swollen, and sore.
This symptom is consistent with iron-deficiency anemia.
Choice B rationale:
"I have a craving for ice all the time." Pica, which involves cravings for non-nutritive substances like ice, is a classic symptom of iron-deficiency anemia.
While the exact cause of pica in iron deficiency is not fully understood, it is considered a manifestation of the body's attempt to obtain more iron.
This unusual craving for ice or other non-food items is a significant indicator of iron-deficiency anemia.
Choice C rationale:
"I've been experiencing chest pain." Chest pain is not a typical manifestation of iron-deficiency anemia.
Instead, it may be associated with other cardiovascular or respiratory conditions.
Iron-deficiency anemia primarily affects the blood's oxygen-carrying capacity and may lead to symptoms such as fatigue, pallor, weakness, and shortness of breath, but chest pain is not a direct consequence of this type of anemia.
Choice D rationale:
"I often faint when I stand up." Fainting upon standing up may be indicative of orthostatic hypotension, which can occur in various medical conditions but is not a specific symptom of iron-deficiency anemia.
Iron-deficiency anemia can lead to weakness and dizziness, but fainting when changing positions may suggest other factors, such as blood pressure regulation issues.
