A primary healthcare provider has instructed a nurse to give 100 fl oz of fluids to a client with renal calculi. What should the nurse do while caring for this client?
Instruct the client to drink 6 cups of fluids.
Provide 2400 mL of fluids daily.
Provide 3 L of fluids daily.
Instruct the client to drink 250 mL of water daily.
The Correct Answer is B
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.

Correct Answer is C
Explanation
The nurse should add 250 mL of water to the formula to dilute it to half strength.
This answer is correct because it is based on a simple ratio and proportion calculation. The nurse can set up a proportion as follows:
250 mL / 1 = x mL / 0.5
Cross-multiplying and solving for x gives:
x = 500 mL
Therefore, the nurse should add 250 mL of water to the formula to make a total volume of 500 mL, which is half the concentration of the original formula.
Correct Answer is A
Explanation
To find the rate in mL/hr, you need to calculate the following:
- The concentration of nitroglycerin in the IV solution in mcg/mL
- The infusion rate in mL/hr using the formula: Infusion rate (mL/h) = (Dose (mcg/min) x 60 min/h) / Concentration (mcg/mL)
First, convert the concentration of nitroglycerin from mg to mcg by multiplying by 1000:
125 mg x 1000 = 125,000 mcg
Then, divide the amount of nitroglycerin by the volume of the IV solution to get the concentration in mcg/mL:
125,000 mcg / 500 mL = 250 mcg/mL
Next, plug in the values into the formula for infusion rate:
Infusion rate (mL/h) = (42 mcg/min x 60 min/h) / 250 mcg/mL
Simplify and solve for the infusion rate:
Infusion rate (mL/h) = 10.08 mL/h
Therefore, the nurse should program the IV pump to deliver **10.1 mL/h** to infuse nitroglycerin at 42 mcg/minute.
