the characteristic symptoms of nephrosis in children is:

Correct Answer: C

Rationale: Nephrosis in children is also known as nephrotic syndrome, which is characterized by the presence of albuminuria (loss of protein in the urine), hypoproteinemia (low levels of protein in the blood), and edema (swelling due to fluid retention). This condition results from damage to the filters in the kidneys, leading to increased permeability and loss of protein in the urine. The classic triad of symptoms in nephrotic syndrome includes proteinuria, hypoalbuminemia, and edema. Other symptoms may include weight gain, frothy urine, and susceptibility to infections. Hematuria, hyperlipidemia, and hypertension are not typical features of nephrotic syndrome in children.

Correct Answer: B

Rationale: Carbamazepine is a known enzyme inducer, and it can increase the metabolism of other drugs, such as phenytoin (Dilantin). This can lead to lower levels of phenytoin in the blood and potentially reduce its effectiveness. Therefore, patients taking carbamazepine should be monitored for elevated levels of phenytoin to ensure optimal seizure control. Diplopia (double vision), leukocytosis, and adult respiratory distress syndrome are not typically associated with carbamazepine use.

Correct Answer: B

Rationale: Using a 1 inch needle is the appropriate gauge needle for drawing up medication and injecting it. The length of the needle is important to ensure that the medication reaches the intended target area and is administered effectively. Shorter needles may not penetrate deep enough, while longer needles may increase the risk of complications such as injecting the medication into the wrong tissue or causing discomfort to the patient. Therefore, using a 1 inch needle is the correct choice for administering medication safely and accurately.

Correct Answer: C

Rationale: Lung involvement, while serious, is less lethal compared to liver, spleen, or hematopoietic system involvement.

Correct Answer: B

Rationale: Hematuria (blood in the urine) is a common finding in glomerulonephritis and causes a tea-colored appearance.
