The health care provider prescribes streptomycin 300 mg IM q12 hours for a client with tuberculosis. The available vial is labeled "Streptomycin 1 gram/2.5 mL." How many milliliters should the nurse administer? (Enter the numerical value only. If rounding is required, round to the nearest tenth.)

Answer and Explanation

The Correct Answer is ["0.8"]

To calculate the number of milliliters the nurse should administer, we can use the following formula:

Dose to administer = Ordered dose / Available dose

In this case, the ordered dose is 300 mg and the available dose is 1 g/2.5 mL. We can calculate the dose to administer as follows:

300 mg / 1000 mg/2.5 mL = 0.75 mL.
Rounded off: 0.8mL

Correct Answer is ["125"]

Explanation

To calculate the infusion rate in mL/hour, we'll use the following formula:

Infusion Rate (mL/hr) = Desired Dose (mEq/hr) / Concentration of Potassium Chloride (mEq/mL)

1. Calculate the concentration of potassium chloride:

Concentration = 80 mEq / 1000 mL = 0.08 mEq/mL

2. Plug in the values:

Infusion Rate (mL/hr) = 10 mEq/hr / 0.08 mEq/mL

3. Calculate:

Infusion Rate (mL/hr) = 125 mL/hr

Therefore, the nurse should regulate the infusion pump to deliver 125 mL/hour.

Correct Answer is ["6"]

Explanation

To calculate the infusion rate in mL/hour, we can use the following formula:

Infusion rate (mL/hour) = Dose (mg/minute) x 60 / Concentration (mg/mL) In this case, the dose is 2 mg/minute and the concentration is:

200 mg/40 mL = 5 mg/mL

We can calculate the infusion rate as follows:

2 mg/minute x 60 / 5 mg/mL = 24 mL/hour

However, the total volume of the solution is 200 mL. Therefore, we need to adjust the infusion rate to ensure that the medication is infused over the correct time period. If we divide the total volume by the infusion time, we can calculate the infusion rate required to deliver the medication over that time period:

200 mL / (120 minutes) = 100 mL/hour

So we need to adjust our initial calculation to ensure that we are infusing at a rate of 100 mL/hour. We can do this by using a proportion:

2 mg/minute x 60 / 5 mg/mL = X mL/hour x 1 Solving for X gives us:

X = (2 x 60 x 1) / 5 = 24 mL/hour

So we should program the infusion pump to deliver 6 mL/hour.
