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 C

Explanation

The number of tablets and their weight only provide information about the total amount of medication in the vial (100 tablets x 333 mg = 33,300 mg or 33.3 g).

A. 21 B. 31 C. 52 D. 62

Correct Answer is B

Explanation

The correct answer is choice B. 31. To find the number of bottles required, use the formula: (dose x frequency x duration) / (bottle size x bottle concentration). In this case, (4 mg/kg x 43 kg x 3 times/day x 6 days) / (100 mg/bottle) = 30.96 bottles. Round up to the nearest whole number to get 31 bottles.
