A nurse is preparing to administer enteral formula to a client who weighs 75 kg and has a caloric need of 2250 calories per day. The nurse finds that 1000 mL of the formula provides 2000 calories.
How much formula would the client need per day (mL/day) to meet the calorie requirements?
500 mL
1125 mL
750 mL
2000 mL
The Correct Answer is B
This is another dosage calculation problem. To solve it, we need to use the formula:
Caloric need ÷ Calories per mL 1000 = Formula per day
In this case, the caloric need is 2250 calories, and the calories per mL is 2000/1000 = 2. Plugging these values into the formula, we get:
2250 ÷ 2 × 1000 = 1125
Therefore, the client would need **1125 mL** of formula per day to meet the calorie requirements.

Correct Answer is B
Explanation
The nurse should administer 60 mL of the supplement in a day.
This answer is correct because it is based on a simple unit conversion and multiplication calculation. The nurse can convert 60 mEq to 20 mL by using the ratio given on the botle label, as follows:
30 mEq / 10 mL = 60 mEq / x mL
Cross-multiplying and solving for x gives:
x = 20 mL
Therefore, the nurse should administer 20 mL of the supplement to deliver 60 mEq of the medication to the patient. Since the order is for three times a day, the nurse should multiply 20 mL by 3 to get the total daily dose, which is 60 mL.
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.
