Correct Answer is ["0.75"]

Explanation

Step 1 is to convert mcg to mg. This is done by dividing the total amount of medication (750 mcg) by 1000 (since 1 mg = 1000 mcg). So, 750 mcg ÷ 1000 = 0.75 mg.

Correct Answer is ["1.2"]

Explanation

Step 1 is to convert the client’s weight from pounds to kilograms since the dosage is ordered in mg/kg. There are approximately 2.2 lb/kg, so 165 lb ÷ 2.2 lb/kg = 75 kg. The doctor ordered phenobarbital at a dosage of 2 mg/kg/day divided into 2 equal doses, so we multiply the client’s wei

Step 1 is to convert the client’s weight from pounds to kilograms since the dosage is prescribed in mg/kg. Given that 1 kg = 2.2 lb, we calculate:

165 lb ÷ 2.2 lb/kg = 75 kg

Step 2 is to determine the total daily dose of phenobarbital. The doctor ordered 2 mg/kg/day, divided into 2 equal doses. So, we first calculate the total daily dose:

75 kg × 2 mg/kg/day = 150 mg/day

Since the medication is to be given in 2 equal doses, we divide:

150 mg/day ÷ 2 = 75 mg/dose

Step 3 is to determine the volume to administer. The medication has a concentration of 65 mg/mL, so we divide the required dose by the concentration:

75 mg ÷ 65 mg/mL = 1.15 mL

Rounding to the nearest tenth, the correct amount to administer is 1.2 mL.

ght in kg by the dosage and divide by 2: (75 kg × 2 mg/kg/day) ÷ 2 = 75 mg/dose. The medication is available at a concentration of 65 mg/mL, so we divide the total mg needed per dose by the mg per mL: 75 mg ÷ 65 mg/mL = 1.15 mL.

So, the correct answer is 1.2 mL.
