The health-care provider prescribes penicillin 700,000 Units IM daily. The available vial is labeled, Penicillin 500,000 Units/ml. How many milliliters should the nurse administer? (Enter numerical value only. If rounding is required, round to the nearest tenth.)
The Correct Answer is ["1.4"]
To calculate the volume of penicillin to be administered, we can use the following formula:
Volume (mL) = Desired Dose (Units) / Concentration (Units/mL)
Plugging in the given values:
Volume (mL) = 700,000 Units / 500,000 Units/mL
Calculating the result:
Volume (mL) = 1.4 mL
Therefore, the nurse should administer 1.4 mL of penicillin.

Correct Answer is ["1.0"]
Explanation
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 ["0.8"]
Explanation
First, calculate the loading dose:
Loading dose = 60 units/kg x 90 kg = 5400 units
Since the maximum loading dose is 4,000 units, the nurse should administer 4,000 units.
Next, calculate the volume to administer:
Volume = Desired Dose (units) / Concentration (units/mL)
Volume = 4,000 units / 5,000 units/mL
Volume = 0.8 mL
Therefore, the nurse should administer 0.8 mL of heparin.
