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 ["100"]

Explanation

To calculate the amount of ammonium chloride needed, we can use the following formula:

Amount of Ammonium Chloride (mEq) = Concentration (mEq/mL) x Volume (mL)

Plugging in the given values:

Amount of Ammonium Chloride = 0.2 mEq/mL x 500 mL

Amount of Ammonium Chloride = 100 mEq

Therefore, the nurse should use 100 mEq of ammonium chloride to prepare the solution.

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.
