Question:

In the preparation of a 3-1 solution, what is the order of adding the ingredients to eliminate the possibility of the emulsion of “oilingout”?

A 2. Fats, amino acids, dextrose

explanation

There are three possible methods of preparing a 3-1 solution: In method 1, amino acids and dextrose are mixed first. Fat emulsion is added next followed by the additives. In method 2, amino acids are added to the fat emulsion. Dextrose is added next followed by the additives. In method 3, dextrose, amino acids, and fat emulsion are added simultaneously while swirling and mixing. Additives are incorporated last.

I have ptcb practices & this type of math is on none of the real practices from the past few years for the ptcb.. Summing up totals? Wasting my time since I see these are not on the actual test why waste my time.

During non-sterile compounding, when should you put on all Personal Protective Equipment (PPE)?

after all formulas and calculations are completed

These steps describe the process for non-sterile compounding:
1. Using the prescription, create a formula for the intended product including any calculations and specific amounts of ingredients needed.
2. Wash hands and put on all required PPE.
3. Obtain any hardware supplies such as a balance or graduated cylinder.
4. Weigh/measure out all ingredients using the proper measurement tools.
5. Following the recipe, combine the ingredients in the correct ratios and in the proper order.
6. Document the exact amounts used and label the final product including final strengths of ingredients.

If two drugs are taken together and one of them intensifies the action of the other, what type of drug interaction has occurred?

Potentiation

Antagonism is when two drugs work against each other. Synergism is when the effect of two drugs together is greater than the sum of their individual effects. Additive Effect is when the effect of two drugs together is equal to the sum of their individual effects.

What type of laminar flow hood can be converted to a type B3 hood?
