A client with rheumatoid arthritis receives a prescription for etanercept 25 mg. The medication is available in a prefilled syringe labeled, 50 mg/2 ml. How many ml should the nurse administer? (Enter the numerical value only.)
The Correct Answer is ["1.0"]
To calculate the volume of etanercept to be administered, we can use the following formula:
Volume (mL) = Desired Dose (mg) / Concentration (mg/mL)
Plugging in the given values:
Volume (mL) = 25 mg / 50 mg/mL
Volume (mL) = 0.5 mL
Since the medication is available in a prefilled syringe labeled 50 mg/2 mL, we need to administer 2 mL to obtain the desired dose of 25 mg.
Therefore, the nurse should administer 1.0 mL of etanercept.

Correct Answer is ["16.8"]
Explanation
To calculate the volume of IV solution needed to dilute the nafcillin, we'll follow these steps:
Step 1: Calculate the total volume of the diluted solution:
Desired Concentration (mg/mL) = Prescribed Dose (mg) / Total Volume (mL)
Rearranging the formula to solve for Total Volume:
Total Volume (mL) = Prescribed Dose (mg) / Desired Concentration (mg/mL)
Total Volume = 800 mg / 40 mg/mL
Total Volume = 20 mL
Step 2: Calculate the volume of nafcillin solution to be added:
Volume of Nafcillin Solution = Prescribed Dose (mg) / Concentration of Nafcillin (mg/mL)
Volume of Nafcillin Solution = 800 mg / 250 mg/mL
Volume of Nafcillin Solution = 3.2 mL
Step 3: Calculate the volume of IV solution needed to dilute:
Volume of IV Solution = Total Volume - Volume of Nafcillin Solution
Volume of IV Solution = 20 mL - 3.2 mL
Volume of IV Solution = 16.8 mL
Therefore, the nurse should add 16.8 mL of IV solution to the volume control device to dilute the nafcillin.
Correct Answer is ["0.13"]
Explanation
To calculate the volume of phytonadione (AquaMEPHYTON) to be administered, we can use the following formula:
Volume (mL) = Desired Dose (mg) / Concentration (mg/mL)
First, let's convert the desired dose from micro-grams to milligrams:
250 mcg x (1 mg / 1000 mcg) = 0.25 mg
Then, plug in the values into the formula:
Volume (mL) = 0.25 mg / 2 mg/mL
Calculating the result:
Volume (mL) = 0.125 mL
Rounding to the nearest hundredth, the nurse should administer 0.13 mL of phytonadione (AquaMEPHYTON).
