Answer and Explanation

The Correct Answer is ["28"]

Given:

Volume of fluid: 1 liter = 1000 mL

Infusion time: 6 hours

Drop factor: 10 gtt/mL

Formula:

Flow rate (gtt/min) = (Volume (mL) / Time (hr)) x Drop factor (gtt/mL) / 60 min/hr

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

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

Infusion rate (mL/hr) = 1000 mL / 6 hr

Infusion rate (mL/hr) = 166.67 mL/hr

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

Flow rate (gtt/min) = (Infusion rate (mL/hr) x Drop factor (gtt/mL)) / 60 min/hr

Flow rate (gtt/min) = (166.67 mL/hr x 10 gtt/mL) / 60 min/hr

Flow rate (gtt/min) = 1666.7 gtt/hr / 60 min/hr

Flow rate (gtt/min) = 27.778 gtt/min

Step 3: Round to the nearest whole number:

Flow rate (gtt/min) ≈ 28 gtt/min

Correct Answer is ["7"]

Explanation

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 ["15"]

Explanation

Given:

Ordered infusion rate: 10 units/kg/hour

Patient weight: 165 pounds

Concentration of Heparin: 25,000 units in 500 mL (50 units/mL)

Step 1: Convert patient weight from pounds to kilograms:

1 pound (lb) = 0.453592 kilograms (kg)

Patient weight in kg = 165 lbs x 0.453592 kg/lb = 74.8 kg

Step 2: Calculate the total dose of Heparin in units/hour:

Total dose (units/hour) = Ordered dose (units/kg/hour) x Patient weight (kg)

Total dose (units/hour) = 10 units/kg/hour x 74.8 kg

Total dose (units/hour) = 748 units/hour

Step 3: Calculate the infusion rate in mL/hour:

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

Infusion rate (mL/hour) = 748 units/hour / 50 units/mL

Infusion rate (mL/hour) = 14.96 mL/hour

Step 4: Round to the nearest whole number:

Infusion rate (mL/hour) ≈ 15 mL/hour
