Answer and Explanation

The Correct Answer is ["140"]

Understanding the Problem:

We need to prepare a 280 ml tube feeding of Ensure that's 50% strength.

Full-strength Ensure comes in 240 ml cans.

Solution:

Determine the volume of Ensure needed:

Since we want a 50% solution, we need to dilute the full-strength Ensure by half.

So, we need 280 ml / 2 = 140 ml of full-strength Ensure.

Therefore, the nurse should use 140 ml of Ensure to prepare the feeding.

Correct Answer is ["3"]

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.

Correct Answer is ["2"]

Explanation

To calculate the number of tablets needed, we can set up a proportion:

x tablets / 3 mg = 1 tablet / 1.5 mg

Cross-multiplying:

1.5x = 3

Solving for x:

x = 3 / 1.5

x = 2

Therefore, the nurse should administer 2 tablets of dexamethasone for each dose.
