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 ["36"]

Explanation

Calculating the Dobutamine Infusion Rate

Step 1: Convert grams to milligrams:

0.5 grams = 500 mg

Step 2: Calculate the concentration of dobutamine in the IV solution:

500 mg / 250 mL = 2 mg/mL

Step 3: Convert micro-grams to milligrams:

1200 mcg x (1 mg / 1000 mcg) = 1.2 mg

Step 4: Set up a proportion:

We want to find the infusion rate in mL/minute.

We know the desired dose rate (1.2 mg/minute) and the concentration of the medication (2 mg/mL).

Proportion:

x mL/minute / 1.2 mg/minute = 1 mL / 2 mg

Step 5: Cross-multiply and solve for x:

2x = 1.2

x = 0.6 mL/minute

Step 6: Convert mL/minute to mL/hour:

0.6 mL/minute x 60 minutes/hour = 36 mL/hour

Therefore, the nurse should program the infusion pump to deliver 36 mL/hour.

Correct Answer is ["1.5"]

Explanation

Calculating the Alprazolam Dose

Problem: Administer 0.75 mg of alprazolam PO. The available concentration is 0.5 mg/tablet.

Steps:

Set up a proportion:

We want to find the number of tablets needed.

We know the desired dose (0.75 mg) and the concentration of the medication (0.5 mg/tablet).

Proportion:

x tablets / 0.75 mg = 1 tablet / 0.5 mg

Cross-multiply:

0.5x = 0.75

Solve for x:

x = 0.75 / 0.5

x = 1.5

Answer: The nurse should administer 1.5 tablets of alprazolam per dose.
