A nurse is preparing to administer regular insulin 0 1 units/kg/hr by continuous tv infusion for a client who weighs 180 lb. Available is regular insulin 500 units in 500 mL of 0.9% sodium chloride. The nurse should set the IV pump to deliver how many mi/hr? (Round to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["8"]
Convert the Client's Weight from Pounds to Kilograms:
1 kg = 2.205 lbs
Weight in kg = 180 lbs / 2.205 lbs/kg
Weight in kg ≈ 81.63 kg
Calculate the Insulin Dose in Units/hr:
Dose = 0.1 units/kg/hr x 81.63 kg
Dose ≈ 8.163 units/hr
Calculate the Insulin Concentration in Units/mL:
Available concentration = 500 units / 500 mL
Concentration = 1 unit/mL
Calculate the Infusion Rate in mL/hr:
Infusion Rate (mL/hr) = Dose in units/hr / Concentration (units/mL)
Infusion Rate (mL/hr) = 8.163 units/hr / 1 unit/mL
Infusion Rate (mL/hr) ≈ 8.163 mL/hr
Round to the Nearest Whole Number:
8 mL/hr

Correct Answer is ["4"]
Explanation
Identify the Desired Dose and Available Concentration:
Desired Dose: 10 mg of verapamil
Available Concentration: 5 mg/2 mL
Simplify the Available Concentration:
To make the calculation easier, find the concentration per 1 mL: 5 mg / 2 mL = 2.5 mg/mL (This means there are 2.5 mg of verapamil in every 1 mL of solution)
Set up the Calculation:
We need to find the volume (in mL) that contains the desired dose of 10 mg.
We can use the following formula:
Volume (mL) = Desired Dose (mg) / Available Concentration (mg/mL)
Plug in the Values and Calculate:
Volume (mL) = 10 mg / 2.5 mg/mL
Volume (mL) = 4 mL
Round to the Nearest Whole Number (if necessary):
4 mL
Correct Answer is ["1.5"]
Explanation
Convert the Client's Weight from Pounds to Kilograms:
1 kg = 2.205 lbs
Weight in kg = 132 lbs / 2.205 lbs/kg
Weight in kg ≈ 59.86 kg
Calculate the Total Dose of Lorazepam Needed:
Dose = 0.05 mg/kg x 59.86 kg
Dose ≈ 2.993 mg
Calculate the Volume of Lorazepam to Administer:
Available concentration = 2 mg/mL
Volume (mL) = Desired dose (mg) / Available concentration (mg/mL)
Volume (mL) = 2.993 mg / 2 mg/mL
Volume (mL) ≈ 1.4965 mL
Round to the Nearest Tenth:
1.5 mL
