A nurse is preparing to administer lactated Ringer's 250 mL IV to infuse over 15 min.
The nurse should set the IV pump to deliver how many mL/hr? (Round the answer to the nearest whole number.
Use a leading zero if it applies.
Do not use a trailing zero.). mL/hr.
The Correct Answer is ["1000"]
Step 1 is to calculate the total volume to be infused in mL/hr. This is done by dividing the total volume (250 mL) by the time in hours (15 min ÷ 60 min/hr). So, 250 mL ÷ (15 min ÷ 60 min/hr) = 1000 mL/hr.
So, the correct answer is 1000 mL/hr.

Correct Answer is ["5"]
Explanation
Step 1 is to calculate the total daily dose. The total daily dose is 150 mg. Step 2 is to divide the total daily dose by the number of doses. The number of doses is 3. So, the calculation is 150 mg ÷ 3 = 50 mg/dose. Step 3 is to calculate the volume to administer using the available medication concentration. The available medication concentration is 50 mg/5 mL. So, the calculation is 50 mg ÷ (50 mg/5 mL) = 5 mL.
So, the correct answer is 5 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.
