Answer and Explanation

The Correct Answer is A

Given:

Volume of fluid: 1000 mL

Infusion time: 8 hours

Drop factor: 15 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 / 8 hr

Infusion rate (mL/hr) = 125 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) = (125 mL/hr x 15 gtt/mL) / 60 min/hr

Flow rate (gtt/min) = 1875 gtt/hr / 60 min/hr

Flow rate (gtt/min) = 31.25 gtt/min

 

Step 3: Round to the nearest whole number:

Flow rate (gtt/min) ≈ 31 gtt/min

Correct Answer is D

Explanation

Convert the dosage to mcg per hour:

55 mcg/min × 60 min = 3300 mcg/hr

Determine the concentration of nitroglycerin available:

The concentration is 25 mg per 250 mL, which converts to 100 mcg/mL.

Calculate the flow rate in mL per hour using the dosage and concentration:

Flowrate(mL/hr)=(Dose(mcg/hr)/Concentration(mcg/mL))

(3300mcg/hr100mcg/mL)=33mL/hr

Correct Answer is A

Explanation

Given:

Value in grams: 5,524 g

To convert grams to kilograms, we need to divide the value by 1000.

Step 1: Divide the value by 1000:

5,524 g / 1000 = 5.524 kg
