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 ["0.5"]
Explanation
Step 1 is to determine the amount of medication needed. This is done by dividing the desired dose by the available dose. So, we have 12.5 mg ÷ 25 mg/mL = 0.5 mL.
So, the correct answer is 0.5 mL.
Correct Answer is ["2.1"]
Explanation
First, we need to calculate the total daily dose of tobramycin for the client. The total daily dose is calculated as follows:
Total daily dose = Dose per kg per day x Weight Total daily dose = 3 mg/kg/day x 85 kg Total daily dose = 255 mg/day
Since the total daily dose is divided into three doses, each dose will be:
Each dose = Total daily dose / Number of doses Each dose = 255 mg / 3 Each dose = 85 mg
Now, we need to convert this dose into mL. We know that we have tobramycin 40 mg/mL, so:
Volume to administer = Each dose / Concentration Volume to administer = 85 mg / 40 mg/mL Volume to administer = 2.125 mL
Rounding this to the nearest tenth, we get 2.1 mL.
