Answer and Explanation

The Correct Answer is ["40"]

Given:

Vial strength: Cefotaxime 2 grams (2000 mg)

Volume of diluent: 50 mL of normal saline

Step 1: Calculate the concentration of Cefotaxime in the reconstituted solution:

Concentration (mg/mL) = Total amount of Cefotaxime (mg) / Total volume of solution (mL)

Concentration (mg/mL) = 2000 mg / 50 mL

Concentration (mg/mL) = 40 mg/mL

Correct Answer is ["120"]

Explanation

Given:

Ordered dose of Labetalol HCl: 2 mg/minute

Concentration of Labetalol HCl: 200 mg in 200 mL (1 mg/mL)

Step 1: Calculate the infusion rate in mg/hour:

Infusion rate (mg/hour) = Ordered dose (mg/minute) x 60 minutes/hour

Infusion rate (mg/hour) = 2 mg/minute x 60 minutes/hour

Infusion rate (mg/hour) = 120 mg/hour

Step 2: Calculate the infusion rate in mL/hour:

Infusion rate (mL/hour) = Infusion rate (mg/hour) / Concentration (mg/mL)

Infusion rate (mL/hour) = 120 mg/hour / 1 mg/mL

Infusion rate (mL/hour) = 120 mL/hour

Correct Answer is ["400"]

Explanation

Given:

Volume of fluid: 1000 mL

Infusion time: 2.5 hours

Formula:

Flow rate (mL/hr) = Volume (mL) / Time (hr)

Step 1: Calculate the infusion rate in mL/hr:

Flow rate (mL/hr) = 1000 mL / 2.5 hr

Flow rate (mL/hr) = 400 mL/hr
