The healthcare provider prescribes a secondary infusion of cefazolin 0.7 gram in 50 mL of D5W to infuse over 30 minutes. The drop factor is 10 gtt/mL. The nurse should regulate the IV to deliver how many drops/minute? (Enter numeric value only. If rounding is required, round to the nearest whole number.)

Answer and Explanation

The Correct Answer is ["17"]

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

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 ["83"]

Explanation

Given:

Volume of fluid: 2 liters (1 liter = 1000 mL, so 2 liters = 2000 mL)

Infusion time: 24 hours

Formula:

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

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

Flow rate (mL/hr) = 2000 mL / 24 hr

Flow rate (mL/hr) = 83.33 mL/hr

Step 2: Round to the nearest whole number:

Flow rate (mL/hr) ≈ 83 mL/hr
