The nurse is reviewing instructions with a client who is to take 120 mL of a carbohydrate balanced meal replacement four times a day. three hours postprandial. The client has a measuring cup marked in ounces. How many ounces should the client take for each dose? (If rounding is required, round to the nearest tenth.)
The Correct Answer is ["4.1"]
The client is to take 120 mL of a carbohydrate balanced meal replacement.
We know that 1 ounce is approximately equivalent to 29.5735 mL.
Therefore, the volume in ounces is:
120mL / 29.5735mL/ounce ≈ 4.06ounces
Rounding to the nearest tenth, the client should take 4.1 ounces for each dose.

Correct Answer is ["0.25"]
Explanation
The vial is labeled as “0.3 mg with 1.2 mL of sterile water.”
Therefore, the concentration of the medication is:
0.3mg / 1.2mL = 0.25mg/mL
The healthcare provider has prescribed a dosage of 0.0625 mg of interferon beta-1b.
So, the volume of medication the nurse should administer is:
0.0625mg / 0.25mg/mL = 0.25mL
So, the nurse should administer 0.25 mL of interferon beta-1b to the client.
Correct Answer is ["0.64"]
Explanation
Here's how to calculate the volume of methylprednisolone the nurse should administer:
1. We know:
Dose to administer: 40 mg (given)
Concentration of the medication: 125 mg per 2 mL (given from the vial label)
2. We need to find:
Volume of medication to administer (mL)
Calculation:
We can set up a proportion to find the volume needed for the desired dose:
Desired dose (mg) / Volume to administer (mL) = Concentration (mg/mL)
Rearrange the formula to solve for the volume:
Volume to administer (mL) = Desired dose (mg) / Concentration (mg/mL)
Plug in the values:
Volume to administer (mL) = 40 mg / (125 mg/2 mL)
Important note: We can divide the concentration by 2 mL because we only need the medication concentration, not the total volume in the vial (which is 2 mL).
Volume to administer (mL) = 40 mg / 62.5 mg/mL (round the concentration to nearest tenth for easier calculation)
Volume to administer (mL) = 0.64 mL (round to nearest hundredth)
Therefore, the nurse should administer 0.64 mL of methylprednisolone.
