A client is receiving Dextrose 5% in Water (DW) 1,000 ml at 75 ml/hour. The nurse hangs the bag of IV fluids at 0300. At what time, based on the 24-hour clock, should the infusion be completed?

1630.

0420.

1620.

0430.

Answer and Explanation

The Correct Answer is C

To calculate the infusion time, we'll use the following formula:

Infusion Time (hours) = Total Volume (mL) / Infusion Rate (mL/hour)

Plugging in the given values:

Infusion Time = 1000 mL / 75 mL/hour

Calculating the result:

Infusion Time ≈ 13.33 hours

Converting hours to minutes:

0.33 hours x 60 minutes/hour ≈ 20 minutes

Therefore, the infusion will be completed approximately 13 hours and 20 minutes after it started at 0300.

Adding 13 hours and 20 minutes to 0300:

0300 + 13 hours + 20 minutes = 1620

So, the correct answer is C. 1620.

Correct Answer is ["499"]

Explanation

Calculating the Lactated Ringer's Infusion Rate

Step 1: Convert pounds to kilograms:

110 pounds x (1 kg / 2.20462 pounds) ≈ 49.9 kg

Step 2: Calculate the total fluid requirement for 24 hours using the Parkland formula:

Total Fluid (mL) = 4 mL/kg/%TBSA x Body Weight (kg) x %TBSA

Total Fluid = 4 mL/kg/%TBSA x 49.9 kg x 40%

Total Fluid = 7984 mL

Step 3: Calculate the fluid volume for the first 8 hours:

First 8 Hours Fluid = Total Fluid / 2

First 8 Hours Fluid = 7984 mL / 2

First 8 Hours Fluid = 3992 mL

Step 4: Calculate the infusion rate for the first 8 hours:

Infusion Rate (mL/hour) = First 8 Hours Fluid / 8 hours

Infusion Rate = 3992 mL / 8 hours

Infusion Rate ≈ 499 mL/hour

Therefore, the nurse should set the infusion pump to deliver approximately 499 mL/hour during the first 8 hours.

Correct Answer is ["3.2"]

Explanation

To calculate the volume of tobramycin sulfate to be administered, we can use the following formula:

Volume (mL) = Desired Dose (mg) / Concentration (mg/mL)

First, let's convert the desired dose from grams to milligrams:

0.128 grams x 1000 mg/gram = 128 mg

Then, plug in the values into the formula:

Volume (mL) = 128 mg / 40 mg/mL

Calculating the result:

Volume (mL) = 3.2 mL

Therefore, the nurse should administer 3.2 mL of tobramycin sulfate.
