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 ["18"]
Explanation
Here's how to calculate the volume (mL/hour) the nurse should program the infusion pump to deliver heparin:
1. We know:
Heparin dose rate: 1,400 units/hour (given by healthcare provider)
Heparin concentration in the IV bag: 20,000 units per 250 mL (given on the label)
2. We need to find:
Volume delivery rate (mL/hour)
3. Calculation:
To find the volume rate, we can divide the heparin dose rate (units/hour) by the heparin concentration (units/mL)
Volume rate (mL/hour) = Heparin dose rate (units/hour) / Heparin concentration (units/mL)
Plug in the values:
Volume rate (mL/hour) = 1,400 units/hour / (20,000 units / 250 mL)
Important note: We can rearrange the fraction with the concentration term because we are dividing by units/mL, which is equivalent to multiplying by mL/units. So, effectively, we are multiplying by the reciprocal of the concentration.
Volume rate (mL/hour) = 1,400 units/hour x (250 mL / 20,000 units)
Volume rate (mL/hour) = 17.5 mL/hour (round to nearest whole number)
Therefore, the nurse should program the infusion pump to deliver 18 mL/hour.
