Order: Augmentin 625 mg IVP8 in 50 mL 0,9% NS q8h over 1hr. Drop factor: 15 gtt/min. Determine rate in ett/min.

A.

14 gtt/min

B.

13 gtt/min

C.

12 gtt/min

D.

15 gtt/min

Answer and Explanation

The Correct Answer is B

Given:
Volume of fluid: 50 mL
Infusion time: 1 hour (60 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) = 50 mL / 60 min
Infusion rate (mL/min) = 0.83 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) = 0.83 mL/min x 15 gtt/mL
Flow rate (gtt/min) = 12.5 gtt/min

Step 3: Round to the nearest whole number:
Flow rate (gtt/min) ≈ 13 gtt/min

Correct Answer is B

Explanation

Given:
Ordered dose of Diazepam: 4 mg
Concentration of Diazepam oral solution: 5 mg/5 mL

Step 1: Set up the proportion:
Desired dose (mg) / Volume to administer (mL) = Concentration (mg/mL)

Step 2: Substitute the values:
4 mg / Volume = 5 mg/5 mL

Step 3: Solve for the unknown volume:
Volume = 4 mg / (5 mg/5 mL)
Volume = 4 mg x (5 mL/5 mg)
Volume = 4 mL

Correct Answer is B

Explanation

Given:

Volume of fluid: 500 mL

Infusion time: 8 hours

Drop factor: 10 gtt/mL

Medication volume: 10 mL (added to the fluid)

Step 1: Calculate the total volume to be infused:

Total volume = Volume of fluid + Volume of medication

Total volume = 500 mL + 10 mL

Total volume = 510 mL

Step 2: Calculate the infusion rate in mL/hr:

Infusion rate (mL/hr) = Total volume (mL) / Infusion time (hr)

Infusion rate (mL/hr) = 510 mL / 8 hr

Infusion rate (mL/hr) = 63.75 mL/hr

Step 3: Calculate the infusion rate in gtt/min:

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

Infusion rate (gtt/min) = 63.75 mL/hr x 10 gtt/mL / 60 min/hr

Infusion rate (gtt/min) = 10.625 gtt/min

Step 4: Round to the nearest whole number:

Infusion rate (gtt/min) ≈ 11 gtt/min
