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.

Answer and Explanation

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 A

Explanation

To set the IV pump correctly, you need to calculate the following:

The patient's weight in kilograms
The dose of Zofran in milligrams
The infusion rate in milliliters per hour

First, convert the patient's weight from pounds to kilograms by dividing by 2.2:

176 lb / 2.2 = 80 kg

Next, multiply the patient's weight by the dose of Zofran per kilogram to get the total dose in milligrams:

80 kg x 0.15 mg/kg = 12 mg

Then, use the formula for infusion rate to find how many milliliters per hour the IV pump should deliver:

Infusion rate (mL/h) = (Total volume (mL) x Flow factor (gt/mL)) / Time (min) x 60 min/h

Since the medication is mixed in 50 mL of normal saline and the infusion time is 15 minutes, plug in these values into the formula:

Infusion rate (mL/h) = (50 mL x 1 gt/mL) / 15 min x 60 min/h

Simplify and solve for the infusion rate:

Infusion rate (mL/h) = 200 mL/h

A. 6.5 mL/hr B. 9.6 mL/hr C. 10.1 mL/hr D. 14.8 mL/hr

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.
