A client is prescribed 25 mg/kg of a medication. The weight of the client is 42 kg.
How many milligrams (mg) of medication should be administered to achieve the total prescribed dose?

1250 mg

1150 mg

950 mg

1050 mg

Answer and Explanation

The Correct Answer is B

The nurse should administer 1050 mg of medication to achieve the total prescribed dose.

This answer is correct because it is based on a simple multiplication calculation. The nurse can multiply the prescribed dose per kilogram by the weight of the client in kilograms to get the total dose in milligrams, as follows:

25 mg/kg x 42 kg = 1050 mg

Therefore, the nurse should administer 1050 mg of medication to the client.

Correct Answer is A

Explanation

To find the rate in mL/hr, you need to calculate the following:

- The concentration of nitroglycerin in the IV solution in mcg/mL
- The infusion rate in mL/hr using the formula: Infusion rate (mL/h) = (Dose (mcg/min) x 60 min/h) / Concentration (mcg/mL)

First, convert the concentration of nitroglycerin from mg to mcg by multiplying by 1000:

125 mg x 1000 = 125,000 mcg

Then, divide the amount of nitroglycerin by the volume of the IV solution to get the concentration in mcg/mL:

125,000 mcg / 500 mL = 250 mcg/mL

Next, plug in the values into the formula for infusion rate:

Infusion rate (mL/h) = (42 mcg/min x 60 min/h) / 250 mcg/mL

Simplify and solve for the infusion rate:

Infusion rate (mL/h) = 10.08 mL/h

Therefore, the nurse should program the IV pump to deliver **10.1 mL/h** to infuse nitroglycerin at 42 mcg/minute.

A. 1000 mL/hr B. 166.67 mL/hr C. 250 mL/hr D. 41.67 mL/hr

Correct Answer is B

Explanation

To find the ﬂow rate in mL/hr, you need to use the formula for infusion rate:

Infusion rate (mL/h) = Total volume (mL) / Time (h)

Since the total volume is 2.5 L and the time is 15 hours, plug in these values into the formula:

Infusion rate (mL/h) = 2.5 L / 15 h

However, before you can simplify and solve for the infusion rate, you need to convert the volume from liters to milliliters by multiplying by 1000:

Infusion rate (mL/h) = 2500 mL / 15 h

Simplify and solve for the infusion rate:

Infusion rate (mL/h) = 166.67 mL/h

Therefore, the ﬂow rate for continuous infusion is **166.67 mL/h**.
