A healthcare provider orders nitroprusside (100 mcg/1 mL) 3 mcg/kg/minute for a patient weighing 154 lb.
What rate (mL/hr) should the nurse program into the IV pump?

1.26 mL/hr

126 mL/hr

1260 mL/hr

12.6 mL/hr

Answer and Explanation

The Correct Answer is D

To answer this question, we need to calculate the infusion rate in mL per hour by using the following formula²:

Infusion rate (mL/h) = Dose (mcg/kg/min) × Weight (kg) × 60 min/h × Volume (mL) / Concentration (mcg/mL)

In this case, the infusion rate is:

Infusion rate (mL/h) = 3 mcg/kg/min × 70 kg × 60 min/h × 250 mL / 2500 mg

We need to convert lb to kg by dividing by 2.2

Infusion rate (mL/h) = 3 mcg/kg/min × (154 lb / 2.2 kg/lb) × 60 min/h × 250 mL / 2500 mg

We need to convert mg to mcg by multiplying by 1000:

Infusion rte (mL/h) = 3 mcg/kg/min × (154 lb / 2.2 kg/lb) × 60 min/h × 250 mL / (2500 mg × 1000 mcg/mg)

We can simplify the equation by canceling out some units and numbers:

Infusion rate (mL/h) = 3 × 154 × 250 / (2.2 × 2500 × 1000)

We can use a calculator to get the final answer:

Infusion rate (mL/h) = 12.6363636363636 mL/h

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**.

A. 1.15 in. B. 1 in. C. 0.06 in. D. 6.45 in.

Correct Answer is B

Explanation

One inch is equal to **2.54 centimeters**²³⁴. To convert inches to centimeters, you can multiply the value in inches by 2.54. For example, 2.54 centimeters x 1 inch = 2.54 centimeters.

Therefore, to convert 2.54 centimeters to inches, you can divide the value in centimeters by 2.54. For example, 2.54 centimeters / 2.54 = 1 inch.

The answer is **1 inch**.
