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.)

Answer and Explanation

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 ["200"]

Explanation

To calculate the infusion rate, we'll use the following formula:

Infusion Rate (mL/hour) = Total Volume (mL) / Infusion Time (hours)

First, convert minutes to hours:

75 minutes x (1 hour / 60 minutes) = 1.25 hours

Then, plug in the values into the formula:

Infusion Rate = 250 mL / 1.25 hours

Calculating the result:

Infusion Rate ≈ 200 mL/hour

Therefore, the nurse should program the secondary infusion pump to deliver 200 mL/hour.

Correct Answer is ["2"]

Explanation

To calculate the number of tablets needed, we'll set up a proportion:

x tablets / 37.5 mg = 1 tablet / 25 mg

Cross-multiplying:

25x = 37.5

Solving for x:

x = 37.5 / 25

x = 1.5

Since we cannot administer a fraction of a tablet, we round up to the nearest whole number.

Therefore, the nurse should administer 2 tablets of atenolol.
