A client with a gastrostomy tube (GT) receives a prescription for Osmolite® 1/2 strength enteral formula at 80 ml/hour. To prepare a 4 hour solution, the nurse should dilute the full-strength formula with how many ml of water? (Enter numeric value only.)

Answer and Explanation

The Correct Answer is ["160"]

To prepare a 4-hour solution of Osmolite® 1/2 strength enteral formula at 80 ml/hour, the nurse will need to dilute the full-strength formula with a certain amount of water.

Step 1: Calculate the total volume of the 1/2 strength formula needed for 4 hours:

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

Total Volume = 80 mL/hour x 4 hours

Total Volume = 320 mL

Step 2: Determine the volume of full-strength Osmolite® needed:

Since the desired solution is 1/2 strength, we need to dilute the full-strength formula by half.

Volume of Full-Strength Osmolite® = Total Volume / 2

Volume of Full-Strength Osmolite® = 320 mL / 2

Volume of Full-Strength Osmolite® = 160 mL

Step 3: Calculate the volume of water needed to dilute the full-strength Osmolite®:

Volume of Water = Total Volume - Volume of Full-Strength Osmolite®

Volume of Water = 320 mL - 160 mL

Volume of Water = 160 mL

Therefore, the nurse should dilute the full-strength Osmolite® with 160 mL of water to prepare a 4-hour solution.

Correct Answer is ["37.3"]

Explanation

To convert Fahrenheit to Celsius, you can use the following formula:

Celsius = (Fahrenheit - 32) x 5/9

In this case, the Fahrenheit temperature is 99.2. Plugging it into the formula:

Celsius = (99.2 - 32) x 5/9

Celsius = 67.2 x 5/9

Celsius = 37.33

Rounding to the nearest tenth, the Celsius temperature is 37.3.

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.
