Question

question 10
which of the following pieces of equipment should a pharmacy technician use to create a fine powder for a capsule?
mortar and pestle
graduated cylinder
hot plate
digital scale

question 11
which of the following statements is true of the air in the compounding area?
the cleanest air is within 6 inches of the sides of the hood.
the cleanest air is within 6 inches of the front of the hood.

Explanation:

Analyze Question 10

The question asks for the equipment used to create a fine powder for a capsule.

• Mortar and pestle: Used in Nonsterile Compounding to grind, crush, and mix solid ingredients (triturating) into a fine powder.
• Graduated cylinder: Used to measure liquid volumes.
• Hot plate: Used to heat substances or melt bases.
• Digital scale: Used to weigh ingredients.

Therefore, the correct choice is the mortar and pestle.

Analyze Question 11

The question asks about the characteristics of the air in the compounding area, specifically inside a laminar airflow hood.

• In a Laminar Airflow Hood, HEPA-filtered air flows continuously to maintain a sterile environment.
• The air closest to the HEPA filter (at the back of a horizontal hood or top of a vertical hood) is the cleanest.
• The air within 6 inches of the front edge, sides, and back of the hood is subject to turbulence and room air intrusion, making it less clean.
• Therefore, the cleanest air is located in the direct compounding area, which must be at least 6 inches inside the hood from the front, sides, and back.
• Let's evaluate the visible options:
• "The cleanest air is within 6 inches of the sides of the hood." (False, these areas have turbulence).
• "The cleanest air is within 6 inches of the front of the hood." (False, this is the zone of turbulence where room air mixes).
• The standard rule is that compounding must be performed at least 6 inches inside the hood to utilize the cleanest air. Thus, the cleanest air is not within the outer 6-inch boundary zones.

Answer:

Question 10

• (A) Mortar and pestle (Correct answer)
• (B) Graduated cylinder
• (C) Hot plate
• (D) Digital scale

Question 11

• (A) The cleanest air is within 6 inches of the sides of the hood.
• (B) The cleanest air is within 6 inches of the front of the hood.
