The health-care provider prescribes furosemide (Lasix) 25 mg IV. The drug is available in a solution of 40 mg/4ml. How many ml should the nurse administer? (Enter numeric value only. If rounding is required, round to the nearest tenth.)

Answer and Explanation

The Correct Answer is ["2.5"]

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

Volume to administer = (Prescribed dose) / (Concentration)

Plugging in the given values:

Volume to administer = 25 mg / (40 mg/4 mL)

Volume to administer = 25 mg x (4 mL / 40 mg)

Volume to administer = 2.5 mL

Therefore, the nurse should administer 2.5 mL of furosemide (Lasix).

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.

Correct Answer is ["206"]

Explanation

Calculation for 3/4 Strength Ensure Feeding

Prompt: To determine how many milliliters of full-strength Ensure to use to prepare a 3/4 strength feeding.

Given:

Desired volume of 3/4 strength Ensure: 275 mL

Strength required: 3/4

Formula:

Amount of full-strength Ensure = Total volume x Strength required

Calculation:

Amount of full-strength Ensure = 275 mL x (3/4)

Amount of full-strength Ensure = (275 x 3) / 4

Amount of full-strength Ensure = 825 / 4

Amount of full-strength Ensure = 206.25 mL

Rounding to the nearest whole number:

Amount of full-strength Ensure = 206 mL

Therefore, the nurse should use 206 mL of full-strength Ensure to prepare the feeding.
