Which of the following congenital heart diseases require multiple surgeries to correct? (Select All that Apply)

A. Weighing the child daily (A) is the most accurate and objective method for monitoring fluid retention in a child with nephrotic syndrome. Nephrotic syndrome can lead to significant fluid retention due to proteinuria and hypoalbuminemia. Daily weight measurements can detect even small changes in body weight, which may be indicative of fluid accumulation. It is a sensitive and specific measure for assessing fluid status.
B. Measuring the abdominal girth weekly (B) can provide some information about abdominal distension, but it is not as precise or sensitive as daily weight measurements. Weight gain or loss can occur without significant changes in abdominal girth, especially in children.
C. Counting the number of wet diapers (C) may provide some information about urinary output, but it does not directly measure overall fluid retention or body weight changes. It is not as reliable as daily weight measurements for assessing fluid status.
D. Testing the urine for hematuria (D) is a valuable diagnostic test to assess kidney function and the presence of blood in the urine, but it does not directly measure fluid retention. Hematuria is not typically the primary indicator of fluid overload in nephrotic syndrome.
In summary, daily weight measurements are the best way to monitor fluid retention in a child with nephrotic syndrome, as they provide a direct and objective assessment of changes in fluid status. This allows healthcare providers to make timely adjustments to the child's treatment plan if necessary.

PDA is a congenital heart defect where a blood vessel called the ductus arteriosus, which is supposed to close shortly after birth, remains open. This allows oxygenated blood from the aorta to flow back into the pulmonary artery, leading to increased pulmonary blood flow and congestion. Over time, this can lead to increased pulmonary vascular congestion and potentially cause complications such as pulmonary hypertension and heart failure.

Surgical repair of PDA, often through a procedure known as ligation or closure of the ductus arteriosus, is performed to stop this abnormal blood flow and prevent the associated complications, particularly the increase in pulmonary vascular congestion.

The other options (B, C, and D) are not the primary complications associated with PDA and surgical repair is not performed primarily to address these issues:

B. Decreased workload on the left side of the heart is not a primary reason for surgical repair of PDA, although it can be a potential benefit of closing the ductus arteriosus.

C. Pulmonary infection is not a direct complication of PDA, but the increased pulmonary blood flow associated with a large PDA can make the lungs more susceptible to respiratory infections.

D. Right-to-left shunt of blood is not a typical complication of PDA. PDA typically involves left-to-right shunting of blood, with oxygenated blood flowing back into the pulmonary circulation, leading to complications related to increased pulmonary blood flow.
