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

A.

10g

B.

25g

C.

50g

D.

100g

Answer and Explanation

The Correct Answer is B

Dextrose 5% in water (D5W) is an IV fluid that contains **5 grams of dextrose** per 100 mL of water². To calculate how many grams of dextrose are in 500 mL of D5W, you can use a simple proportion:

5 g / 100 mL = x g / 500 mL

Cross-multiply and solve for x:

x = (5 g * 500 mL) / 100 mL

x = 25 g

Therefore, there are **25 grams of dextrose** in 500 mL of D5W.

Correct Answer is B

Explanation

This number should be multiplied by inches in order to convert a patient's height measurement from inches to centimeters, because one inch is equal to 2.54 centimeters. To convert inches to centimeters, the formula is:

centimeters = inches × 2.54

For example, if a patient's height is 60 inches, then the height in centimeters is:

centimeters = 60 × 2.54
centimeters = 152.4

Therefore, the patient's height is 152.4 centimeters.

Correct Answer is B

Explanation

One fluid ounce is equal to **29.57353 milliliters**¹²³. To convert fluid ounces to milliliters, you can multiply the value in fluid ounces by 29.57353. For example, 1 fluid ounce x 29.57353 milliliters = 29.57353 milliliters.

Therefore, to convert 100 fl oz of fluids to milliliters, you can multiply 100 by 29.57353. The answer is
**2957.353 milliliters**. This is the amount of fluids that the nurse should provide to the client with renal calculi.

The other options are not correct because they do not match the calculated amount of fluids that the client needs. Option a is wrong because it is too litle fluids, which could result in dehydration or inadequate flushing of the urinary tract. Option c is wrong because it is too much fluids, which could result in fluid overload or electrolyte imbalance. Option d is wrong because it is not a volume but a frequency, and it is also too litle fluids for the client's condition.
