If rounding is required, round to the nearest whole number.)

Answer and Explanation

The Correct Answer is ["7"]

Given:

Ordered dose of Nesiritide: 0.01 mcg/kg/minute

Patient weight: 155.1 pounds

Bag size: 250 mL D5W

Concentration of Nesiritide: 1.5 mg

Step 1: Convert patient weight from pounds to kilograms:

1 pound (lb) = 0.453592 kilograms (kg)

Patient weight in kg = 155.1 lbs x 0.453592 kg/lb = 70.3 kg

Step 2: Calculate the total dose of Nesiritide in mcg/minute:

Total dose (mcg/minute) = Ordered dose (mcg/kg/minute) x Patient weight (kg)

Total dose (mcg/minute) = 0.01 mcg/kg/minute x 70.3 kg

Total dose (mcg/minute) = 0.703 mcg/minute

Step 3: Convert mcg/minute to mg/hour:

Total dose (mg/hour) = Total dose (mcg/minute) x 60 minutes/hour / 1000 mcg/mg

Total dose (mg/hour) = 0.703 mcg/minute x 60 minutes/hour / 1000 mcg/mg

Total dose (mg/hour) = 0.04218 mg/hour

Step 4: Calculate the infusion rate in mL/hour:

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

Infusion rate (mL/hour) = 0.04218 mg/hour / (1.5 mg/250 mL)

Infusion rate (mL/hour) = 0.04218 mg/hour x (250 mL/1.5 mg)

Infusion rate (mL/hour) = 7.03 mL/hour

Step 5: Round to the nearest whole number:

Infusion rate (mL/hour) ≈ 7 mL/hour

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 ["1"]

Explanation

Given:

Ordered dose of trimethobenzamide: 100 mg IM every 6 hours

Concentration of trimethobenzamide: 200 mg/2 mL vial

Step 1: Set up the proportion:

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

Step 2: Substitute the values:

100 mg / Volume = 200 mg/2 mL

Step 3: Solve for the unknown volume:

Volume = 100 mg / (200 mg/2 mL)

Volume = 100 mg x (2 mL / 200 mg)

Volume = 1 mL
