1. what is the brand or trade name of this drug?
2. what is the generic name of this drug?

Explanation:

Step1: Analyze question 20

The label says "FOR IV USE AFTER DILUTION".

Step2: Analyze question 21

The label says "DISCARD UNUSED PORTION".

Step3: Analyze question 22

The concentration is \(50\) mg/mL. Use the formula \(V=\frac{D}{C}\), where \(D = 125\) mg and \(C=50\) mg/mL. So \(V=\frac{125}{50}=2.5\) mL.

Step4: Analyze question 23

The label says "Zaroxolyn® Tablets".

Step5: Analyze question 24

The label says "(metolazone tablets, USP)".

Answer:

1. It is administered via intravenous (IV) route after dilution.
2. No, the unused portion should be discarded.
3. \(2.5\) mL.
4. Zaroxolyn.
5. Metolazone.
