A nurse is preparing to administer filgrastim 250 mcg, subcutaneous. How many mg should the nurse administer? (Round the answer to the nearest hundredth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["0.25"]
Order: Filgrastim 250 mcg (micrograms)
Desired Unit: mg (milligrams)
Step 1: Conversion Factor
We need to know the relationship between micrograms (mcg) and milligrams (mg).
1 mg = 1000 mcg
Step 2: Set Up the Conversion
We want to convert 250 mcg to mg. To do this, we'll divide the given dose (250 mcg) by the conversion factor (1000 mcg/mg):
250 mcg x (1 mg / 1000 mcg)
Step 3: Perform the Calculation
Multiply the numerators: 250 x 1 = 250
Multiply the denominators: 1 x 1000 = 1000
Divide the result: 250 / 1000 = 0.25
Step 4: Answer with Correct Units and Rounding
The result is 0.25 mg.
The problem asks us to round to the nearest hundredth, which we already have (0.25).
The problem also states to use a leading zero if it applies (which it does) and not use a
trailing zero (which we don't have).
Answer: 0.25 mg

Correct Answer is ["8"]
Explanation
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 ["4.5"]
Explanation
Calculate the Insulin Dose in Units/hr:
Dose = 0.1 units/kg/hr x 45 kg
Dose = 4.5 units/hr
Determine the Insulin Concentration in Units/mL:
Available concentration = 1 unit/mL (given in the problem)
Calculate the Infusion Rate in mL/hr:
Infusion Rate (mL/hr) = Dose in units/hr / Concentration (units/mL)
Infusion Rate (mL/hr) = 4.5 units/hr / 1 unit/mL
Infusion Rate (mL/hr) = 4.5 mL/hr
Round to the Nearest Tenth (if necessary):
4.5 mL/hr
