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 ["2000"]
Explanation
To calculate the infusion rate of magnesium sulfate, we'll follow these steps:
1. Calculate the concentration of magnesium sulfate in the IV solution:
Magnesium Sulfate Concentration = Magnesium Sulfate (g) / Solution Volume (mL)
Magnesium Sulfate Concentration = 4 grams / 250 mL
Magnesium Sulfate Concentration = 16 mg/mL
2. Calculate the magnesium sulfate infusion rate in mg/hour:
Magnesium Sulfate Infusion Rate = Infusion Rate (mL/hour) x Magnesium Sulfate Concentration (mg/mL)
Magnesium Sulfate Infusion Rate = 125 mL/hour x 16 mg/mL
Magnesium Sulfate Infusion Rate = 2000 mg/hour
Therefore, the nurse should administer 2000 mg/hour of magnesium sulfate.
Correct Answer is ["100"]
Explanation
To calculate the amount of ammonium chloride needed, we can use the following formula:
Amount of Ammonium Chloride (mEq) = Concentration (mEq/mL) x Volume (mL)
Plugging in the given values:
Amount of Ammonium Chloride = 0.2 mEq/mL x 500 mL
Amount of Ammonium Chloride = 100 mEq
Therefore, the nurse should use 100 mEq of ammonium chloride to prepare the solution.
