How should the nurse set the IV pump to deliver the correct dose?
100 mL/hr
150 mL/hr
200 mL/hr
400 mL/hr
The Correct Answer is C
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.

Correct Answer is B
Explanation
To calculate the dose of digoxin in micrograms (mcg) that the child should receive, we need to first convert the weight of the child from pounds to kilograms:.
30 lb / 2.205 = 13.61 kg.
Next, we can calculate the dose of digoxin in mcg:. Dose (in mcg) = Weight (in kg) x Dose (in mcg/kg). Dose (in mcg) = 13.61 kg x 10 mcg/kg.
Dose (in mcg) = 136.1 mcg.
Now we need to calculate the volume of digoxin solution to administer. Since the concentration of the digoxin solution is 1 mg/mL, we can use proportion to calculate the volume:.
1 mg is to 1 mL as 136.1 mcg is to X mL. 1/1 = 136.1/X.
Cross-multiplying, we get:. 1X = 136.1 x 1.
X = 136.1 mL.
Therefore, the nurse should administer 0.1361 mL (136.1 mcg) of digoxin to the child.
Correct Answer is B
Explanation
To calculate the answer, we can use the following formula:.
(mg of drug required / total mg in vial) x total volume in vial = mL to administer. First, let's convert the dose from mg to g:.
80 mg = 0.08 g.
Next, let's plug in the values:. (0.08 g / 1 g) x 8 mL = 0.64 mL.
Therefore, the nurse should administer 0.64 mL of Solu-Medrol.
