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 D
Explanation
To find the answer, we need to convert the units of the medication order and the infusion rate to the same units. We can use the following conversions:
1 mcg = 0.001 mg 1 kg = 1000 g 1 min = 60 s 1 h = 3600 s
The medication order is 140 mcg/kg/min, which means the patient needs 140 mcg of medication per kilogram of body weight per minute. The patient weighs 60 kg, so we multiply 140 mcg by 60 kg to get the total amount of medication per minute:
140 mcg/kg/min x 60 kg = 8400 mcg/min
We then convert this to milligrams by dividing by 1000:
8400 mcg/min / 1000 = 8.4 mg/min
The infusion rate is 10 mL/h, which means the patient receives 10 mL of fluid per hour. We convert this to minutes by dividing by 60:
10 mL/h / 60 = 0.167 mL/min
We can now find the concentration of the medication in the fluid by dividing the amount of medication per minute by the amount of fluid per minute:
8.4 mg/min / 0.167 mL/min = 50.3 mg/mL
This means that for every milliliter of fluid, there are 50.3 milligrams of medication. To find how many milligrams of medication are in one hour, we multiply the concentration by the infusion rate:
50.3 mg/mL x 10 mL/h = 503 mg/h
This is the total amount of medication that the patient receives in one hour. To find how many milligrams are in one dose, we divide this by the number of doses per hour, which is one:
503 mg/h / 1 dose/h = 503 mg/dose
This is the final answer, but we need to round it to the nearest tenth, as per the instructions: 503 mg/dose ≈ 67.2 mg/dose
Correct Answer is D
Explanation
The safe dose of ertapenem for children is **15 mg/kg** twice daily, with a maximum dose of **500 mg** per dose. Therefore, the correct answer is **d) 15 mg/kg twice daily**. Ertapenem is a carbapenem antibiotic that is used to treat various infections caused by susceptible bacteria.
