360 mcg

Explanation:

First Question (Preparing 1L of 3% NaCl solution)

Step1: Understand percentage solution

A 3% NaCl solution means 3 grams of NaCl per 100 mL of solution (since percentage weight/volume is g per 100 mL for aqueous solutions in pharmacy).

Step2: Convert volume to mL

1 L = 1000 mL.

Step3: Calculate amount of NaCl

If 100 mL needs 3 g, then 1000 mL (1 L) needs $\frac{3\ g}{100\ mL} \times 1000\ mL = 30\ g$.

Step1: Understand "qid"

"qid" means 4 times a day.

Step2: Calculate daily dosage

Each puff is 90 mcg, and take 1 puff 4 times a day. So total daily dosage is $90\ mcg/puff \times 1 \ puff \times 4 \ times = 360\ mcg$.

Answer:

30 g (the option with 30 g)
