A patient is receiving an IV of 500 mL D5W (dextrose 5% in water). How many grams (g) of dextrose are contained in this IV solution?

10 g

25 g

50 g

100 g

Answer and Explanation

The Correct Answer is C

D5W is a solution that contains 5% dextrose in water. This means that for every 100 mL of solution, there are 5 g of dextrose. The patient is receiving an IV of 500 mL D5W. Therefore, the total amount of dextrose in this IV solution is (500 mL) * (5 g / 100 mL) = 25 g.

A. 10 g is incorrect because it is less than the calculated amount of dextrose.

B. 25 g is incorrect because it is half the calculated amount of dextrose.

C. 50 g is the correct answer.

D. 100 g is incorrect because it is double the calculated amount of dextrose.

Correct Answer is D

Explanation

To calculate the total volume of IV ﬂuid being infused, we need to multiply the infusion rate ratio (2.75 mL/min) by the total time (7 hours) and then convert the result to liters.

2.75 mL/min * 60 min/hour * 7 hours = 1155 mL

To convert mL to liters, we divide by 1000:

1155 mL / 1000 = 1.155 L

Therefore, the total volume of IV ﬂuid being infused is d. 1.155 L.

A. 1.161 L: This value is slightly higher and does not match the calculated result.

B. 1.25 L: This value is significantly higher and does not match the calculated result.

C. 1.15 L: This value is slightly lower and does not match the calculated result.

Therefore, the correct total volume of IV ﬂuid being infused is d. 1.155 L, as calculated based on the given infusion rate ratio and total time.

A. 2.25 B. 2.75 C. 3.1 D. 2.54

Correct Answer is D

Explanation

To convert a measurement from inches to centimeters, we need to multiply the measurement by the conversion factor of 2.54. This conversion factor represents the number of centimeters in one inch.

So, to convert a patient's height measurement from inches to centimeters, we would multiply the

measurement by 2.54.

Therefore, the correct answer is d. 2.54.
