Correct Answer is ["0.5"]

Explanation

Given:

Ordered dose of interferon beta-1b: 0.125 mg

Vial strength: 0.3 mg

Reconstitution volume: 1.2 mL

Step 1: Determine the concentration of the reconstituted solution:

Concentration (mg/mL) = Total amount of medication (mg) / Volume of solution (mL)

Concentration (mg/mL) = 0.3 mg / 1.2 mL

Concentration (mg/mL) = 0.25 mg/mL

Step 2: Calculate the volume to be administered:

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

Volume (mL) = 0.125 mg / 0.25 mg/mL

Volume (mL) = 0.5 mL

Correct Answer is ["125"]

Explanation

Given:

Total dose of Potassium Chloride: 80 mEq

Volume of solution: 1 liter (1000 mL)

Infusion rate: 10 mEq/hour

Step 1: Determine the concentration of Potassium Chloride in the solution:

Concentration (mEq/mL) = Total Potassium Chloride (mEq) / Volume of solution (mL)

Concentration (mEq/mL) = 80 mEq / 1000 mL

Concentration (mEq/mL) = 0.08 mEq/mL

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

Infusion rate (mL/hr) = Infusion rate (mEq/hr) / Concentration (mEq/mL)

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

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