Question

1. How many grams of sodium are in 150ml of 0.9% NS? ROOUND TO THE NEAREST 10TH.

2 How many grams of dextrose are in 750mls of D5W? ROOUND TO THE NEAREST 10TH.

Answer 1

Here we can use the formula for finding the answer is;

(Concentration % / 100) X Volume in mL = Dosage amount in Gram

Q1.   How many grams of sodium are in 150ml of 0.9% NS?

Concentration - 0.9%

Volume - 150 mL

(Concentration % / 100) X Volume in mL = Dosage amount in Gram

(0.9 / 100) X 150 ml = (0.0009) X 150 = 0.135 grams of sodium

In the case of ROUND TO THE NEAREST 10TH the answer is 0.1 gram sodium

0.1 grams of sodium are in 150ml of 0.9% NS

Q2. How many grams of dextrose are in 750mls of D5W?

Concentration - 5%

Volume - 750 mL

(Concentration % / 100) X Volume in mL = Dosage amount in Gram

(5 / 100) X 750 ml = (0.05) X 750 = 37.5 grams of dextrose

In the case of ROUND TO THE NEAREST 10TH, the answer is 37.5 gram dextrose

37.5 grams of dextrose are in 750 ml of D5W
