A client receives a prescription for fentanyl 100 mcg IV every 1 to 2 hours PRN for severe pain. The medication is available in 0.05 mg/mL vial. How many ml should the nurse administer? (Enter numerical value only.)

Answer and Explanation

The Correct Answer is ["2"]

Given:

Ordered dose of Fentanyl: 100 mcg

Concentration of Fentanyl: 0.05 mg/mL

Step 1: Convert mcg to mg:

Ordered dose (mg) = Ordered dose (mcg) / 1000 mcg/mg

Ordered dose (mg) = 100 mcg / 1000 mcg/mg

Ordered dose (mg) = 0.1 mg

Step 2: Set up the proportion:

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

Step 3: Substitute the values:

0.1 mg / Volume = 0.05 mg/mL

Step 4: Solve for the unknown volume:

Volume = 0.1 mg / (0.05 mg/mL)

Volume = 0.1 mg x (1 mL / 0.05 mg)

Volume = 2 mL

Correct Answer is ["38"]

Explanation

Given:

Volume of fluid: 75 mL

Infusion time: 30 minutes

Drop factor: 15 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) = 75 mL / 30 min

Infusion rate (mL/min) = 2.5 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) = 2.5 mL/min x 15 gtt/mL

Flow rate (gtt/min) = 37.5 gtt/min

Step 3: Round to the nearest whole number:

Flow rate (gtt/min) ≈ 38 gtt/min

Correct Answer is ["8"]

Explanation

Given:

Ordered infusion rate: 320 units/hour

Concentration of Heparin: 20,000 units in 500 mL (40 units/mL)

Formula:

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

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

Infusion rate (mL/hr) = 320 units/hr / 40 units/mL

Infusion rate (mL/hr) = 8 mL/hr
