Correct Answer is ["24"]

Explanation

- Step 1: Identify the prescribed dose in units per hour. The client is scheduled to receive 1,200 units/hr of heparin.

- Step 2: Identify the concentration of the available solution. The available solution contains 25,000 units of heparin in 500 mL D5W.

- Step 3: Calculate the volume of solution needed to deliver the required dose. We can set up a proportion to solve for this:

- 25,000 units is to 500 mL as 1,200 units is to X mL.

- In other words, 25,000 units : 500 mL = 1,200 units : X mL.

- Step 4: Solve for X using cross-multiplication and division:

- Cross-multiplication gives us: 25,000 units × X mL = 1,200 units × 500 mL.

- Simplifying this gives us: 25,000X = 600,000.

- Dividing both sides by 25,000 gives us: X = 600,000 ÷ 25,000.

- Calculating the division gives us: X = 24.

Set the IV pump to deliver 24 mL/hr to administer the required dose of 1,200 units/hr.

Correct Answer is ["1.2"]

Explanation

- Step 1: Identify the child's weight in pounds. The child weighs 33 lbs.

- Step 2: Convert the child's weight from pounds to kilograms. We know that 1 kg = 2.2 lbs. So, 33 lbs = 33 ÷ 2.2 kg. Calculating the division gives us approximately 15 kg.

- Step 3: Identify the prescribed dose in mcg/kg/day. The child is scheduled to receive 8 mcg/kg/day of digoxin, divided equally every 12 hours.

- Step 4: Calculate the total daily dose in mcg. We can do this by multiplying the child's weight in kg by the prescribed dose in mcg/kg:

- Total daily dose = 8 mcg/kg/day × 15 kg.

- Calculating the multiplication gives us: Total daily dose = 120 mcg/day.

- Step 5: Since the dose is divided equally every 12 hours, we divide the total daily dose by 2 to get the dose per administration:

- Dose per administration = Total daily dose ÷ 2.

- Dose per administration = 120 mcg ÷ 2.

- Calculating the division gives us: Dose per administration = 60 mcg.

- Step 6: Identify the concentration of the available solution. The available solution contains 0.05 mg/mL of digoxin. Convert this to mcg/mL for consistency with the dose per administration. We know that 1 mg = 1000 mcg. So, 0.05 mg = 0.05 × 1000 mcg = 50 mcg/mL.

- Step 7: Calculate the volume of solution needed to deliver the required dose. We can set up a proportion to solve for this:

- 50 mcg is to 1 mL as 60 mcg is to X mL.

- In other words, 50 mcg : 1 mL = 60 mcg : X mL.

- Step 8: Solve for X using cross-multiplication and division:

- Cross-multiplication gives us: 50 mcg × X mL = 60 mcg × 1 mL.

- Simplifying this gives us: 50X = 60.

- Dividing both sides by 50 gives us: X = 60 ÷ 50.

- Calculating the division gives us: X = 1.2.

Administer 1.2 mL of the digoxin elixir per dose.
