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"]
To convert micrograms to milligrams, divide by 1000: 250 mcg / 1000 = 0.25 mg. Round to the nearest hundredth: 0.25 mg. Therefore, the nurse should administer 0.25 mg of filgrastim.

Correct Answer is ["30"]
Explanation
To solve this problem, the nurse needs to convert the client's weight from pounds to kilograms, and then use the formula:
mL/hr = (mcg/kg/min x kg x 60 min) / (mg/mL x 1000 mcg/mg)
The client's weight in kilograms is:
110 lb / 2.2 lb/kg = 50 kg
The concentration of dobutamine in mg/mL is:
250 mg / 250 mL = 1 mg/mL
Plugging these values into the formula, we get:
mL/hr = (10 mcg/kg/min x 50 kg x 60 min) / (1 mg/mL x 1000 mcg/mg) mL/hr = (30,000 mcg/min) / (1000 mcg/mg)
mL/hr = 30 mg/min
mL/hr = 30 mL/hr
Therefore, the nurse should set the IV pump to deliver 30 mL/hr.
Correct Answer is ["15"]
Explanation
To answer this question, we need to calculate the dose of esmolol in mcg/kg/min, then convert it to mg/hr, and then use the formula:
mL/hr = (dose in mg/hr) x (volume in mL) / (concentration in mg)
First, we convert the client's weight from pounds to kilograms:
110 lb x 1 kg / 2.2 lb = 50 kg
Next, we multiply the client's weight by the prescribed dose to get the dose in mcg/min: 50 kg x 50 mcg/kg/min = 2500 mcg/min
Then, we divide the dose in mcg/min by 1000 to get the dose in mg/min: 2500 mcg/min / 1000 = 2.5 mg/min
Finally, we multiply the dose in mg/min by 60 to get the dose in mg/hr: 2.5 mg/min x 60 = 150 mg/hr
Now, we can use the formula to find the infusion rate in mL/hr:
mL/hr = (150 mg/hr) x (250 mL) / (2500 mg)
mL/hr = 15
Therefore, the nurse should set the IV pump to deliver 15 mL/hr.
