A client is prescribed a drug as 0.3 mcg, q4h. Calculate the dose of the medicine per day.

A.

1.2 mcg/day

B.

1.8 mcg/day

C.

0.9 mcg/day

D.

1.5 mcg/day

Answer and Explanation

The Correct Answer is B

The dose of the medicine per day is 1.8 mcg.

This answer is correct because it is based on a simple multiplication calculation. The nurse should follow these steps to calculate the dose of the medicine per day:

1) Divide 24 hours by the frequency of the dose to get the number of doses per day, as follows:

24 / 4 = 6

Therefore, the client will receive 6 doses of the medicine per day.

2) Multiply the number of doses per day by the amount of each dose to get the total dose per day, as follows:

6 x 0.3 mcg = 1.8 mcg

Therefore, the dose of the medicine per day is 1.8 mcg.

Correct Answer is A

Explanation

To find the milligrams per minute, you need to calculate the following:

- The volume of Lopressor in milliliters
- The infusion rate in milliliters per minute using the formula: Infusion rate (mL/min) = Total volume (mL) / Time (min)
- The dose of Lopressor in milligrams per minute using the formula: Dose (mg/min) = Infusion rate (mL/min) x Concentration (mg/mL)


First, divide the dose of Lopressor by the concentration to get the volume in milliliters:


5 mg / 1 mg/mL = 5 mL

Next, use the formula for infusion rate to find how many milliliters per minute the IV pump should deliver:


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


Since the total volume is 5 mL and the time is 2 minutes, plug in these values into the formula:


Infusion rate (mL/min) = 5 mL / 2 min


Simplify and solve for the infusion rate:


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


Then, use the formula for dose to find how many milligrams per minute the patient should receive:


Dose (mg/min) = Infusion rate (mL/min) x Concentration (mg/mL)


Since the infusion rate is 2.5 mL/min and the concentration is 1 mg/mL, plug in these values into the formula:


Dose (mg/min) = 2.5 mL/min x 1 mg/mL


Simplify and solve for the dose:


Dose (mg/min) = 2.5 mg/min


Therefore, the patient should receive **2.5 mg/min** of Lopressor.
