100 ml.

4 ml.

10 ml.

Answer and Explanation

The Correct Answer is C

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

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

Plugging in the given values:

Volume (mL) = 500 mg / 125 mg/mL

Calculating the result:

Volume (mL) = 20 mL

Therefore, the nurse should administer 20 mL of amoxicillin.

The correct answer is C. 20 ml.

Correct Answer is C

Explanation

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.

Explanation

Calculating the Trimethoprim-Sulfamethoxazole Dose

Problem: Administer 120 mg of Bactrim-DS Oral Suspension. The available concentration is 200 mg/5 mL.

Steps:

Set up a proportion:

We want to find the number of milliliters (mL) needed.

We know the desired dose (120 mg) and the concentration of the medication (200 mg/5 mL).

Proportion:

x mL / 120 mg = 5 mL / 200 mg

Cross-multiply:

200x = 600

Solve for x:

x = 600 / 200

x = 3

Answer: The nurse should administer 3 mL of Bactrim-DS Oral Suspension per dose.
