Correct Answer is C
Explanation
We can use the following formula to calculate the infusion rate:
Infusion rate (mL/hr) = (Dose ordered in mcg/min x Volume to be infused in mL) / Dose available in mg
First, we need to convert the dose ordered from mg/min to mcg/min: 125 mg = 125,000 mcg
125,000 mcg/500 mL = 250 mcg/mL
Now we can plug in the values we have into the formula:
Infusion rate (mL/hr) = (42 mcg/min x 60 min x 24 hours) / (250 mcg/mL) Infusion rate (mL/hr) = 10.08 mL/hr
Rounding to the nearest tenth, the answer is C. 10.1 mL/hr.
Therefore, the nurse should program the IV pump to deliver the nitroglycerin at a rate of 10.1 mL/hr to achieve the ordered dose of 42 mcg/minute.
Correct Answer is C
Explanation
The patient is ordered to receive 0.15 mg/kg of Zofran over 15 minutes. The patient weighs 176 lb, which is equivalent to 80 kg. To calculate the total amount of Zofran the patient should receive, multiply the weight by the dosage:
80 kg x 0.15 mg/kg = 12 mg
The Zofran arrives from the pharmacy mixed in 50 mL of normal saline, which means there is 12 mg of Zofran in 50 mL of solution. To calculate how many milliliters per hour the nurse should set the IV pump, we can use the following formula:
50 mL / 0.25 hour = X mL per hour X = 200 mL per hour
Therefore, the nurse should set the IV pump to deliver 200 mL of Zofran per hour to the patient.
