Round your answer to the nearest tenth.

0.65 mL/hr

9.6 mL/hr

10.1 mL/hr

14.8 mL/hr

Answer and Explanation

The Correct Answer is C

We can use the following formula to calculate the infusion rate:

Infusion rate (mL/hr) = (Dose ordered in mcg/min x Volume to be infused in mL) / Dose available in mg

First, we need to convert the dose ordered from mg/min to mcg/min: 125 mg = 125,000 mcg

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

Now we can plug in the values we have into the formula:

Infusion rate (mL/hr) = (42 mcg/min x 60 min x 24 hours) / (250 mcg/mL) Infusion rate (mL/hr) = 10.08 mL/hr

Rounding to the nearest tenth, the answer is C. 10.1 mL/hr.

Therefore, the nurse should program the IV pump to deliver the nitroglycerin at a rate of 10.1 mL/hr to achieve the ordered dose of 42 mcg/minute.

Correct Answer is A

Explanation

To calculate the time it will take to finish the infusion, we can use the formula:

Time = Volume / Rate

Plugging in the given values, we get:

Time = 1.5 L / 75 mL/hr Converting 1.5 L to mL, we get:

Time = 1500 mL / 75 mL/hr Simplifying, we get:

Time = 20 hours

Therefore, it will take 20 hours to finish the infusion at the current rate.

A. 0.14 mL B. 0.136 mL C. 136 mL D. 300 mL

Correct Answer is B

Explanation

To calculate the dose of digoxin in micrograms (mcg) that the child should receive, we need to first convert the weight of the child from pounds to kilograms:.

30 lb / 2.205 = 13.61 kg.

Next, we can calculate the dose of digoxin in mcg:. Dose (in mcg) = Weight (in kg) x Dose (in mcg/kg). Dose (in mcg) = 13.61 kg x 10 mcg/kg.

Dose (in mcg) = 136.1 mcg.

Now we need to calculate the volume of digoxin solution to administer. Since the concentration of the digoxin solution is 1 mg/mL, we can use proportion to calculate the volume:.

1 mg is to 1 mL as 136.1 mcg is to X mL. 1/1 = 136.1/X.

Cross-multiplying, we get:. 1X = 136.1 x 1.

X = 136.1 mL.

Therefore, the nurse should administer 0.1361 mL (136.1 mcg) of digoxin to the child.
