A primary healthcare provider prescribes an enteral feeding formula to a client. A nurse finds that the formula's full strength concentration volume is 250 mL.
How much water should the nurse add to the formula to dilute it to half strength?
50 mL
100 mL
250 mL
500 mL
The Correct Answer is C
To dilute the enteral feeding formula to half strength, we need to add an equal volume of water to the formula. Therefore, we need to add 250 mL of water to the 250 mL of full strength formula to make a total volume of 500 mL at half strength..
So the nurse should add 250 mL of water to the formula to dilute it to half strength.

Correct Answer is B
Explanation
We can use the following formula to calculate the infusion time:
Infusion time (in hours) = Remaining volume (in mL) / Infusion rate (in mL/hr)
First, let's convert the current time to minutes since we will be calculating the infusion time in minutes as well:
19:30 = 19 hours x 60 minutes/hour + 30 minutes = 1170 minutes Now we can substitute the given values into the formula:
Infusion time (in hours) = 376 mL / 40 mL/hr Infusion time (in hours) = 9.4 hours
To convert this to hours and minutes, we can separate the integer and decimal parts of the answer:
9 hours (integer part) and 0.4 hours x 60 minutes/hour = 24 minutes (decimal part)
Therefore, the infusion time is 9 hours and 24 minutes, and the infusion will finish at approximately 04:54 (19:30 + 9 hours and 24 minutes).
