A nurse is preparing to administer lidocaine 4 mg/min by continuous IV infusion. Available is lidocaine 1 g in dextrose 5% in water 250 ml. 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.)
The Correct Answer is ["60"]
To calculate the infusion rate of lidocaine, we need to convert the dose from mg/min to mg/hr and then to mL/hr.
The prescribed dose is 4 mg/min, so the hourly dose is 4 x 60 = 240 mg/hr.
The concentration of the drug is 1 g in 250 mL, which is equivalent to 1000 mg in 250 mL or 4 mg in 1 mL.
Therefore, the volume per hour is 240 / 4 = 60 mL/hr.
Rounded to the nearest whole number, the nurse should set the IV pump to deliver 60 mL/hr.

Correct Answer is ["200"]
Explanation
To answer this question, we need to calculate the infusion rate of the IV pump. The formula for infusion rate is:
Infusion rate (mL/hr) = Volume (mL) / Time (hr)
We are given the volume of the solution, which is 50 mL, and the time of administration, which is 15 minutes or 0.25 hours. Plugging these values into the formula, we get:
Infusion rate (mL/hr) = 50 mL / 0.25 hr
Infusion rate (mL/hr) = 200 mL/hr
Therefore, the nurse should set the IV pump to deliver 200 mL/hr. This is the answer to the question.

Correct Answer is ["0.8"]
Explanation
To calculate the dose of enoxaparin, we need to convert the client's weight from pounds to kilograms.
1 kg=2.2 Ib
? kg= 165Ib
=165/2.2
=75kg
Desired med is 1mg/kg
total dose to administer= 75mg
Available formulation is 30mg/0.3ml
total volume to administer
30mg=0.3ml
75mg= 75*0.3/30
=0.75ml
Rounded off to the nearest tenth = 0.8ml
