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 C
Explanation
In transposition of the great vessels (TGV), the aorta and the pulmonary artery are switched, causing oxygen-rich blood to be pumped back to the lungs and oxygen-poor blood to be pumped out to the body. The ductus arteriosus, a fetal blood vessel that normally closes shortly after birth, allows blood to mix between the two circulations.
Prostaglandin E1 is used to keep the ductus arteriosus open, allowing for a controlled mixing of oxygenated and deoxygenated blood, which can improve oxygen delivery to the body in cases of TGV. This helps maintain oxygenation until corrective surgical interventions can be performed.
The other options, A (decrease pulmonary congestion), B (stimulate the production of red blood cells), and D (increase blood flow to the system), do not accurately describe the primary purpose of Prostaglandin E1 in the context of TGV. The main goal is to maintain a pathway for oxygenated blood to mix with deoxygenated blood to improve oxygen delivery to the body.
Correct Answer is C
Explanation
Options A (increased ability of tissue to retain fluid) and B (reduced blood pressure) are not typical signs of improvement in Nephrotic Syndrome. The primary focus is on reducing protein loss and alleviating edema.
Option C. Increased diuresis and decreased protein loss in urine.
Nephrotic Syndrome is characterized by increased urinary protein loss, resulting in hypoalbuminemia, edema, and other symptoms. Improvement in Nephrotic Syndrome is typically indicated by:
Increased diuresis: An increase in urine output suggests that the child is excreting excess fluid, which can help reduce edema (swelling).
Decreased protein loss in urine: A reduction in proteinuria (loss of protein in the urine) is a positive sign, as it indicates that the damaged kidney glomeruli are functioning more effectively in retaining protein.
Option D (decreased protein levels in serum) is also not a clear sign of improvement. While it may be related to reduced protein loss in urine, it does not directly reflect the overall improvement of the condition. Monitoring protein levels in the urine (proteinuria) is a more specific indicator of Nephrotic Syndrome management.
