The health-care provider prescribes propofol (Diprivan) at 8 mcg/kg/minute for a client during conscious sedation. The drug is dispensed as a secondary infusion labeled, 0.9% normal saline 50 ml with propofol 100 mg/50 ml The client's weight is 198 pounds. The nurse should program the infusion pump to deliver how many ml/hour? (Enter numeric value only. If rounding is required, round to the nearest tenth.)

Answer and Explanation

The Correct Answer is ["22"]

Calculating the Propofol Infusion Rate

Step 1: Convert weight to kilograms:

198 lbs x (1 kg / 2.20462 lbs) ≈ 90 kg

Step 2: Calculate the desired dose rate in mcg/minute:

8 mcg/kg/minute x 90 kg = 720 mcg/minute

Step 3: Calculate the concentration of propofol in the IV solution:

100 mg/50 mL = 2 mg/mL

Step 4: Calculate the infusion rate in mL/hour:

First, convert mcg to mg:

720 mcg x (1 mg / 1000 mcg) = 0.72 mg/minute

Then, set up a proportion:

x mL/hour / 0.72 mg/minute = 60 minutes/hour / 2 mg/mL

Cross-multiply and solve for x:

x mL/hour = 0.72 mg/minute x 60 minutes/hour / 2 mg/mL

x mL/hour ≈ 21.6 mL/hour

Therefore, the nurse should program the infusion pump to deliver approximately 22 mL/hour.

Correct Answer is ["1"]

Explanation

To calculate the number of additional tablets needed, we'll first determine the total number of tablets required for the new dose of 30 mg.

Step 1: Calculate the total number of tablets needed for the new dose:

Total Tablets = Desired Dose (mg) / Tablet Strength (mg)

Total Tablets = 30 mg / 15 mg/tablet

Total Tablets = 2 tablets

Step 2: Determine the number of tablets already administered:

The client already received 1 tablet today.

Step 3: Calculate the number of additional tablets needed:

Additional Tablets = Total Tablets - Tablets Already Administered

Additional Tablets = 2 tablets - 1 tablet

Additional Tablets = 1 tablet

Therefore, the nurse should administer 1 additional tablet of aripiprazole (Abilify) to reach the total newly prescribed dose for the day.

Correct Answer is ["0.13"]

Explanation

To calculate the volume of phytonadione (AquaMEPHYTON) to be administered, we can use the following formula:

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

First, let's convert the desired dose from micro-grams to milligrams:

250 mcg x (1 mg / 1000 mcg) = 0.25 mg

Then, plug in the values into the formula:

Volume (mL) = 0.25 mg / 2 mg/mL

Calculating the result:

Volume (mL) = 0.125 mL

Rounding to the nearest hundredth, the nurse should administer 0.13 mL of phytonadione (AquaMEPHYTON).
