How many grams of dextrose are in 1,000 mL of D10W?
1,000 grams
10 grams
100 grams
1 gram
The Correct Answer is C
Calculation:
D10W stands for Dextrose 10% in Water.2 This means the solution contains 10 grams of dextrose for every 100 mL of solution.
- Calculate the total grams of dextrose in 1,000 mL.
Using a ratio:
10 g/100 mL =x/1000 mL.
To solve for x:
x= (10 g×1000 mL)/ 100mL
=10 g×10
=100 grams

Correct Answer is ["0.67"]
Explanation
Desired dose = 8 mg.
Concentration of the available medication = 6 mg in 0.5 mL.
Concentration = 6 mg / 0.5 mL
= 12 mg/mL.
- Calculate the volume in milliliters (mL) to administer.
Volume (mL) = Desired dose (mg) / Concentration (mg/mL)
= 8 mg / 12 mg/mL
= 0.6666... mL.
- Rounding to the nearest hundredth
= 0.67 mL.
Correct Answer is ["167"]
Explanation
Given values:
Total volume = 1,000 mL
Infusion time = 6 h
- Calculate the flow rate in mL/h using the formula:
Flow rate (mL/h) = Total volume (mL) / Infusion time (h)
= 1000 mL / 6 h
= 166.6667 mL/h.
- Round the answer to the nearest whole number.
= 167 mL/h.
