A nurse has to administer 10 mcg/kg of digoxin to a client who weighs 30 lb. The nurse has available digoxin 1 mg/mL. How many mL would the nurse administer to the child?

0.14 mL

0.136 mL

136 mL

300 mL

Answer and Explanation

The Correct Answer is B

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 infusion rate in mL/hr, we need to divide the total volume to be infused by the time for infusion and convert the units appropriately.

First, we need to convert the time of infusion from hours to minutes, since most IV pumps use minutes as the time unit.

2 hours x 60 minutes/hour = 120 minutes Next, we can calculate the infusion rate:

500 mL ÷ 120 minutes = 4.17 mL/minute

To convert mL/minute to mL/hour, we multiply by 60:

4.17 mL/minute x 60 minutes/hour = 250 mL/hour

Therefore, the correct answer is B. 250 mL/hr. The nurse should set the IV pump to deliver the LR infusion at a rate of 250 mL/hr to infuse 500 mL over 2 hours.

A. 23 mg B. 6.8 mg C. 23.8 mg D. 20.59 mg

Correct Answer is C

Explanation

To calculate the dose of ondansetron for this client, we need to use the client's weight and the prescribed dose of 0.34 mg/kg.

The formula to calculate the dose is:

Dose (in mg) = Weight (in kg) x Dose (in mg/kg) So, for this client:

Dose (in mg) = 70 kg x 0.34 mg/kg

Dose (in mg) = 23.8 mg (rounded to one decimal place)

Therefore, the client should receive a dose of 23.8 mg of ondansetron, 30 minutes prior to chemotherapy.
