A client who weighs 65 kg is receiving an infusion of Dextrose 5% in Water (DW) 250 ml with dopamine 400 mg at 12 ml/hour. How many mcg/kg/minute is the client receiving? (Enter numeric value only. If rounding is required, round to the nearest tenth.)

Answer and Explanation

The Correct Answer is ["4.9"]

Step 1: Calculate the concentration of dopamine in the IV solution:

400 mg / 250 mL = 1.6 mg/mL

Step 2: Calculate the infusion rate in mL/minute:

12 mL/hour x (1 hour / 60 minutes) = 0.2 mL/minute

Step 3: Calculate the dopamine infusion rate in mg/minute:

0.2 mL/minute x 1.6 mg/mL = 0.32 mg/minute

Step 4: Convert milligrams to micro-grams:

0.32 mg x (1000 mcg / 1 mg) = 320 mcg/minute

Step 5: Calculate the dopamine infusion rate in mcg/kg/minute:

320 mcg/minute / 65 kg ≈ 4.9 mcg/kg/minute

Therefore, the client is receiving approximately 4.9 mcg/kg/minute of dopamine.

Correct Answer is ["1.5"]

Explanation

Understanding the Problem:

We need to administer 15 mg of furosemide.

The available ampoule contains 10 mg/mL of furosemide.

Solution:

Set up a proportion:

We want to find the number of milliliters (mL) needed.

We know the desired dose (15 mg) and the concentration of the medication (10 mg/mL).

Proportion:

x mL / 15 mg = 1 mL / 10 mg

Cross-multiply:

10x = 15

Solve for x:

x = 15 / 10

x = 1.5

Therefore, the nurse should administer 1.5 mL of furosemide.

Correct Answer is ["10.5"]

Explanation

To calculate the volume of pyridostigmine to be administered, we can use the following formula:

Volume (mL) = Desired Dose (mg) / Concentration (mg/mL)

However, the concentration is given in mg/5 mL. We need to convert it to mg/mL:

Concentration (mg/mL) = 60 mg / 5 mL = 12 mg/mL

Now, plug in the given values into the formula:

Volume (mL) = 126 mg / 12 mg/mL

Volume (mL) = 10.5 mL

Therefore, the nurse should administer 10.5 mL of pyridostigmine syrup.
