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?

A.

50 mL

B.

100 mL

C.

250 mL

D.

500 mL

Answer and Explanation

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 A

Explanation

First, we need to convert the weight of the child from pounds to kilograms:. 44 lb / 2.2046 = 19.958 kg (rounded to three decimal places).

Next, we can calculate the dose of glycopyrrolate:. 0.02 mg/kg x 19.958 kg = 0.39916 mg.

We should always check our calculation and verify that the dose is appropriate and safe for the child. In this case, the dose of 0.39916 mg seems reasonable for a child with chronic severe drooling..

Now, we need to determine how much medication to administer to the child. We know that 5 mL of medication contains 1 mg of drug. Therefore, to administer 0.39916 mg of glycopyrrolate, we need to administer:

(0.39916 mg / 1 mg) x 5 mL = 1.9958 mL.

We should round this dose to the nearest appropriate unit of measure. In this case, we can round to 2 mL to make it easier to measure and administer..

Therefore, the nurse should administer 2 mL of glycopyrrolate to the child three times a day (tid) to treat chronic severe drooling.

Correct Answer is C

Explanation

The number of tablets and their weight only provide information about the total amount of medication in the vial (100 tablets x 333 mg = 33,300 mg or 33.3 g).
