How many grams of NaCl are in 500 mL of ½ NS (0.45%)?
1.125g
1.175g
2.25g
2.65g
2.25g
Rationale: There are 2.25g of NaCl in 500 mL of ½ NS (0.45%). To calculate this answer, convert % (0.45%) to a decimal (0.0045). Then, solve it by using the following equation: FVX% (decimal) = Amount of AI (g) or 500 mL x 0.0045 = 2.25g
