Heparin protocol is prescribed for a client weighing 90 kg. Per protocol, the heparin loading dose is 60 units/kg IV rounded to the nearest 100 units, with a maximum loading dose of 4,000 units. The heparin vial is labeled 5,000 units/ml. How many ml should the nurse administer? (Enter the numeric value only. If rounding is required, round to the nearest tenth.)
The Correct Answer is ["0.8"]
First, calculate the loading dose:
Loading dose = 60 units/kg x 90 kg = 5400 units
Since the maximum loading dose is 4,000 units, the nurse should administer 4,000 units.
Next, calculate the volume to administer:
Volume = Desired Dose (units) / Concentration (units/mL)
Volume = 4,000 units / 5,000 units/mL
Volume = 0.8 mL
Therefore, the nurse should administer 0.8 mL of heparin.

Correct Answer is ["0.8"]
Explanation
First, calculate the loading dose:
Loading dose = 60 units/kg x 90 kg = 5400 units
Since the maximum loading dose is 4,000 units, the nurse should administer 4,000 units.
Next, calculate the volume to administer:
Volume = Desired Dose (units) / Concentration (units/mL)
Volume = 4,000 units / 5,000 units/mL
Volume = 0.8 mL
Therefore, the nurse should administer 0.8 mL of heparin.
Correct Answer is ["40"]
Explanation
Calculating the Inamrinone Infusion Rate
Step 1: Convert weight to kilograms:
183 lbs x (1 kg / 2.20462 lbs) ≈ 83.0 kg
Step 2: Calculate the desired dose rate in mcg/minute:
8 mcg/kg/minute x 83.0 kg ≈ 664 mcg/minute
Step 3: Calculate the concentration of inamrinone in the IV solution:
0.1 grams/100 mL = 100 mg/100 mL = 1 mg/mL
Step 4: Calculate the infusion rate in mL/hour:
First, convert mcg to mg:
664 mcg x (1 mg / 1000 mcg) = 0.664 mg/minute
Then, set up a proportion:
x mL/hour / 0.664 mg/minute = 60 minutes/hour / 1 mg/mL
Cross-multiply and solve for x:
x mL/hour = 0.664 mg/minute x 60 minutes/hour / 1 mg/mL
x mL/hour ≈ 40 mL/hour
Therefore, the nurse should program the infusion pump to deliver approximately 40 mL/hour.
