A client is receiving a prescription for penicillin 1.2 million units IM. The available vial is labeled, "600,000 units/2 mL". How many mL should the nurse administer?
(Enter numeric value only)
The Correct Answer is ["4"]
The client is receiving a prescription for penicillin 1.2 million units IM.
The available vial is labeled "600,000 units/2 mL", so the concentration of penicillin in the solution is 300,000 units/mL (600,000 units / 2 mL).
Since the healthcare provider prescribes 1.2 million units of penicillin, the nurse should administer 4 mL of medication (1.2 million units / 300,000 units/mL).

Correct Answer is ["6"]
Explanation
To calculate the infusion rate in mL/hour, we can use the following formula:
Infusion rate (mL/hour) = Dose (mg/minute) x 60 / Concentration (mg/mL) In this case, the dose is 2 mg/minute and the concentration is:
200 mg/40 mL = 5 mg/mL
We can calculate the infusion rate as follows:
2 mg/minute x 60 / 5 mg/mL = 24 mL/hour
However, the total volume of the solution is 200 mL. Therefore, we need to adjust the infusion rate to ensure that the medication is infused over the correct time period. If we divide the total volume by the infusion time, we can calculate the infusion rate required to deliver the medication over that time period:
200 mL / (120 minutes) = 100 mL/hour
So we need to adjust our initial calculation to ensure that we are infusing at a rate of 100 mL/hour. We can do this by using a proportion:
2 mg/minute x 60 / 5 mg/mL = X mL/hour x 1 Solving for X gives us:
X = (2 x 60 x 1) / 5 = 24 mL/hour
So we should program the infusion pump to deliver 6 mL/hour.
Correct Answer is ["125"]
Explanation
To calculate the infusion rate in mL/hour, we'll use the following formula:
Infusion Rate (mL/hr) = Desired Dose (mEq/hr) / Concentration of Potassium Chloride (mEq/mL)
1. Calculate the concentration of potassium chloride:
Concentration = 80 mEq / 1000 mL = 0.08 mEq/mL
2. Plug in the values:
Infusion Rate (mL/hr) = 10 mEq/hr / 0.08 mEq/mL
3. Calculate:
Infusion Rate (mL/hr) = 125 mL/hr
Therefore, the nurse should regulate the infusion pump to deliver 125 mL/hour.
