Which of the following Reticulocyte count is an indicator of severe anemia for an infant?
3%
8%
0.5%
5%
The Correct Answer is B
The reticulocyte count is a measure of young, immature red blood cells. An elevated reticulocyte count indicates the bone marrow's ability to respond to anemia by producing new red blood cells.
For an infant, a reticulocyte count of 8% would be an indicator of severe anemia. An elevated reticulocyte count suggests the body is trying to compensate for the decreased number of mature red blood cells by producing more young ones. This is often seen in severe anemia as the body attempts to increase the red blood cell count.
The other options (A, C, and D) represent normal or less severe reticulocyte counts.
A reticulocyte count of 3% is within the normal range.
A reticulocyte count of 0.5% is on the lower side but not as severe as 8%.
A reticulocyte count of 5% indicates a response to anemia but is not as elevated as 8%.

Correct Answer is D
Explanation
Option A, "Fatigue," is a symptom of anemia but is not a long-term complication associated with Thalassemia major.
Option B, "Deferoxamine usage," is a treatment to manage iron overload and not a complication associated with Thalassemia major.
Option C, "Immunosuppressive therapy," is not typically used to manage Thalassemia major and is not a long-term complication but rather a potential treatment for certain cases of thalassemia.
Option D. Hemochromatosis/Hemosiderosis
Thalassemia major is a genetic disorder that results in the body's inability to produce enough hemoglobin, leading to severe anemia.
To manage this condition, frequent blood transfusions are required, which can lead to iron overload in the body. Excess iron gets deposited in various organs and tissues, causing damage.
Hemochromatosis or hemosiderosis is a condition characterized by the accumulation of iron in organs like the liver, heart, and endocrine glands, which can result from repeated blood transfusions.
The complications associated with iron overload include liver damage, heart problems, diabetes, and more. Treatment with iron chelating agents like deferoxamine is often necessary to remove excess iron from the body.
Correct Answer is C
Explanation
A. "That big soft spot will be covered in bone by the end of the second month" is not accurate. The closure usually occurs later than the second month.
B. "The big soft spot will close at around 24 months of age" is an overestimation of the typical closure time. It is usually closed earlier than 24 months.
C. "The big soft spot is usually closed between 12 and 18 months of age."
The anterior fontanel is the soft spot located on the baby's head, and its closure is a natural part of an infant's development. The timing of closure can vary from one child to another. However, the typical range for the closure of the anterior fontanel is between 12 and 18 months of age. This information provides a general guideline for parents while acknowledging the natural variability in child development.
D. "Babies' soft spots close at different times depending on their growth rate" is true to some extent, but providing a general range (option C) is more informative for parents.
