Answer and Explanation

The Correct Answer is ["1"]

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

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 ["17"]

Explanation

Given:

Volume of fluid: 50 mL

Infusion time: 30 minutes

Drop factor: 10 gtt/mL

Formula:

Flow rate (gtt/min) = (Volume (mL) / Time (min)) x Drop factor (gtt/mL)

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

Infusion rate (mL/min) = Volume (mL) / Time (min)

Infusion rate (mL/min) = 50 mL / 30 min

Infusion rate (mL/min) = 1.67 mL/min

Step 2: Calculate the flow rate in gtt/min:

Flow rate (gtt/min) = Infusion rate (mL/min) x Drop factor (gtt/mL)

Flow rate (gtt/min) = 1.67 mL/min x 10 gtt/mL

Flow rate (gtt/min) = 16.7 gtt/min

Step 3: Round to the nearest whole number:

Flow rate (gtt/min) ≈ 17 gtt/min
