he nurse is preparing to administer methylprednisolone 40 mg IV. The medication vial is labeled, "125 mg per 2 mL. How many mLs of medication should the nurse administer? (Enter numeric value only. If rounding is required, round to the nearest hundredth

Answer and Explanation

The Correct Answer is ["0.64"]

Here's the calculation:

Prescribed dose: 40 mg methylprednisolone

Medication vial concentration: 125 mg per 2 mL (given on the vial label)

We need to find the volume (mL) containing the prescribed dose (40 mg) of methylprednisolone.

Calculation:

Concentration adjustment: The concentration is given in mg per 2 mL. To calculate the medication needed for the 40 mg dose, we need the concentration in mg/mL.

Concentration (mg/mL) = Total mg / Volume (mL)

Concentration (mg/mL) = 125 mg / 2 mL

Concentration (mg/mL) = 62.5 mg/mL

Volume to administer:

Volume to administer (mL) = Dose (mg) / Concentration (mg/mL)

Volume to administer (mL) = 40 mg / 62.5 mg/mL

Volume to administer (mL) = 0.64 mL (round to nearest hundredth)

Therefore, the nurse should administer 0.64 mL of methylprednisolone.

Correct Answer is ["31"]

Explanation

Here's how to calculate the infusion rate (gtt/min) for the nurse to regulate:

1. We know the following:

Total vancomycin dose: 1500 mg

Volume of solution: 250 mL

Infusion time: 2 hours

IV administration set gtt/mL: 15 gtt/mL

2. We need to find the infusion rate in gtt/min.

Steps:

a. Calculate the concentration of vancomycin in the solution:

Concentration (mg/mL) = Total dose (mg) / Volume (mL)

Concentration (mg/mL) = 1500 mg / 250 mL

Concentration (mg/mL) = 6 mg/mL (round to nearest whole number)

b. Convert infusion time from hours to minutes:

Infusion time (minutes) = Infusion time (hours) x Minutes per hour

Infusion time (minutes) = 2 hours * 60 minutes/hour

Infusion time (minutes) = 120 minutes

c. Calculate the total volume of solution to be infused per minute:

Total volume rate (mL/min) = Total volume (mL) / Infusion time (minutes)

Total volume rate (mL/min) = 250 mL / 120 minutes

Total volume rate (mL/min) = 2.083 mL/min (round to nearest hundredth)

d. Finally, calculate the infusion rate in gtt/min:

Infusion rate (gtt/min) = Volume rate (mL/min) x gtt/mL

Infusion rate (gtt/min) = 2.083 mL/min * 15 gtt/mL

Infusion rate (gtt/min) = 31.25 gtt/min (round to nearest whole number as requested)

Therefore, the nurse should regulate the infusion at approximately 31 gtt/min.

Correct Answer is ["0.7"]

Explanation

The nurse should administer 0.7 mL of diphenhydramine.

Here's the calculation:

Medication dosage: 35 mg (diphenhydramine)

Medication concentration: 50 mg/mL (given on the syringe label)

We need to find the volume (mL) containing the prescribed dose (35 mg) of diphenhydramine.

Volume to administer (mL) = Dose (mg) / Concentration (mg/mL)

Volume to administer (mL) = 35 mg / 50 mg/mL

Volume to administer (mL) = 0.7 mL (round to nearest tenth)

Therefore, the nurse should administer 0.7 mL of diphenhydramine
