A client is receiving an IV solution of 2 grams of medication diluted in 100 ml of normal saline over a one hour time period. How many mg of medication is the client receiving per minute? (Enter numeric value only. If rounding is required, round to the nearest whole number.)

Answer and Explanation

The Correct Answer is ["33"]

Step 1: Calculate the concentration of the medication:

Concentration (mg/mL) = Total Medication (mg) / Total Volume (mL)

Concentration = 2000 mg / 100 mL

Concentration = 20 mg/mL

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

Infusion Rate (mg/minute) = Infusion Rate (mL/hour) x Concentration (mg/mL) x (1 hour / 60 minutes)

Infusion Rate = 100 mL/hour x 20 mg/mL x (1 hour / 60 minutes)

Infusion Rate = 33.33 mg/minute

Rounding to the nearest whole number, the client is receiving 33 mg of medication per minute.

Correct Answer is ["5.8"]

Explanation

To calculate the infusion rate, we'll follow these steps:

1. Calculate the desired dose rate in mcg/minute:

Desired Dose Rate = Weight (kg) x Dose (mcg/kg/minute)

Desired Dose Rate = 86 kg x 8 mcg/kg/minute

Desired Dose Rate = 688 mcg/minute

2. Convert micro-grams to milligrams:

688 mcg x (1 mg / 1000 mcg) = 0.688 mg/minute

3. Calculate the concentration of dopamine in the IV solution:

Dopamine Concentration = Dopamine (mg) / Solution Volume (mL)

Dopamine Concentration = 800 mg / 500 mL

Dopamine Concentration = 1.6 mg/mL

4. Set up a proportion:

x mL/hour / 0.688 mg/minute = 60 minutes/hour / 1.6 mg/mL

5. Cross-multiply and solve for x:

x mL/hour = 0.688 mg/minute x 60 minutes/hour / 1.6 mg/mL

x mL/hour ≈ 25.8 mL/hour

Therefore, the nurse should program the infusion pump to deliver approximately 25.8 mL/hour.

Correct Answer is ["2"]

Explanation

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

x tablets / 500 mg = 1 tablet / 250 mg

Cross-multiplying:

250x = 500

Solving for x:

x = 500 / 250

x = 2

Therefore, the nurse should administer 2 tablets of azithromycin per dose.
