(Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["150"]

Step 1 is to determine the rate of infusion. This is done by dividing the total volume by the total time. So, we have 1200 mL ÷ 8 hr = 150 mL/hr.

So, the correct answer is 150 mL/hr.

Correct Answer is ["57"]

Explanation

Step 1 is to convert the client’s weight from pounds to kilograms. We know that 1 kg is approximately 2.2 lb. So, the client’s weight in kg is 178 lb ÷ 2.2 lb/kg = 80.91 kg. Step 2 is to calculate the total dose of acetylcysteine. The total dose is 140 mg/kg × 80.91 kg = 11327.4 mg. Step 3 is to calculate the volume to administer. The volume is 11327.4 mg ÷ 200 mg/mL = 56.637 mL.

So, the correct answer is 57 mL after rounding to the nearest whole number.

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.
