A nurse is preparing to administer potassium glucose 40 mEq PO. Available is potassium gluconate liquid 20 mEq/15 mL. How many mL should the nurse administer? (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 ["30"]

Understanding the Problem

Order: Potassium gluconate 40 mEq PO

Available Solution: Potassium gluconate liquid 20 mEq/15 mL

Desired Dose: mL to administer

Step 1: Set Up the Calculation

We need to find the volume (in mL) that contains the ordered dose (40 mEq). We can do this by setting up a proportion or using the formula:

Volume (mL) = (Ordered Dose (mEq) / Concentration (mEq/mL))

Step 2: Determine the Concentration

Available Concentration: 20 mEq / 15 mL

Step 3: Perform the Calculation

Ordered Dose: 40 mEq

Concentration: 20 mEq / 15 mL

Volume: (40 mEq) / (20 mEq / 15 mL) = (40 mEq X 15 mL) / 20 mEq

We can simplify this by dividing 40 by 20:

Volume: (2 X 15 mL) = 30 mL

Step 4: Round to the Nearest Whole Number

The result is 30 mL, which is already a whole number.

Answer: 30 mL

Correct Answer is ["25"]

Explanation

Identify the Total Volume and Infusion Time:

Total Volume: 100 mL

Infusion Time: 4 hours

Calculate the Infusion Rate (mL/hr):

We need to find out how many mL should be infused per hour.

We can use the following formula:

Infusion Rate (mL/hr) = Total Volume (mL) / Infusion Time (hours)

Plug in the Values and Calculate:

Infusion Rate (mL/hr) = 100 mL / 4 hours

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

Round to the Nearest Whole Number (if necessary):

25 mL/hr

Correct Answer is ["38"]

Explanation

Identify the Given Information:

Infusion Rate: 150 mL/hr

Drop Factor: 15 gtt/mL

Convert the Infusion Rate to mL/min:

There are 60 minutes in 1 hour.

Infusion Rate (mL/min) = 150 mL/hr / 60 min/hr

Infusion Rate (mL/min) = 2.5 mL/min

Calculate the Drip Rate (gtt/min):

Drip Rate (gtt/min) = Infusion Rate (mL/min) x Drop Factor (gtt/mL)

Drip Rate (gtt/min) = 2.5 mL/min x 15 gtt/mL

Drip Rate (gtt/min) = 37.5 gtt/min

Round to the Nearest Whole Number:

38 gtt/min
