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
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
Step 1: Determine the dosage ratio. 60 mg (ordered) ÷ 70 mg (available) = 0.8571 (rounded to 4 decimal places)
Step 2: Calculate the volume to administer. 0.8571 × 75 mL (available) = 64.2857 mL (rounded to 4 decimal places)
Step 3: Round to the nearest whole number. 64.2857 mL rounds to 64 mL
So, the nurse should administer 64 mL to the patient.
The correct answer is B. 64 mL.
The correct answer is B. 64 mL.
Correct Answer is B
Explanation
The correct answer is choice B. 2 bottles. To find the number of bottles required, use the formula: (dose x duration) / (bottle size x tablet strength). In this case, (600 mg/day x 7 days) / (7 tablets/bottle x 300 mg/tablet) = 2 bottles.
