The physician ordered 2/3 strength Ensure 6 oz PO q4h for 24 hrs. What is the total volume in mL you would administer in 24 hrs?

A.

60 mL

B.

120 mL

C.

180 mL

D.

1080 mL

Answer and Explanation

The Correct Answer is D

Convert ounces to millilitres (1 oz = 29.5735 mL):

6 oz×29.5735 mL/oz=177.441 mL6

Calculate the frequency of doses per day:

The patient receives a dose every 4 hours, so in 24 hours, the number of doses is:

24 hours/4 hours/dose=6 doses

Calculate the total volume for all doses:

177.441 mL/dose×6 doses=1064.646 mL

Rounding to the nearest whole number=1080 mL

Correct Answer is B

Explanation

The order directly states that the infusion rate is 30 mL/hr.

The information about the amount of Lidocaine (2 g) and the volume of D5W (250 mL) is irrelevant to determining the flow rate in this case.

The flow rate is already specified as 30 mL/hr in the order.

Correct Answer is B

Explanation

Given:

Volume of fluid: 100 mL

Infusion time: 4 hours

Drop factor: 60 gtt/mL

Formula:

Flow rate (gtt/min) = (Volume (mL) / Time (hr)) x Drop factor (gtt/mL) / 60 min/hr

Step 1: Calculate the infusion rate in mL/hr:

Infusion rate (mL/hr) = Volume (mL) / Time (hr)

Infusion rate (mL/hr) = 100 mL / 4 hr

Infusion rate (mL/hr) = 25 mL/hr

Step 2: Calculate the flow rate in gtt/min:

Flow rate (gtt/min) = (Infusion rate (mL/hr) x Drop factor (gtt/mL)) / 60 min/hr

Flow rate (gtt/min) = (25 mL/hr x 60 gtt/mL) / 60 min/hr

Flow rate (gtt/min) = 1500 gtt/hr / 60 min/hr

Flow rate (gtt/min) = 25 gtt/min
