Question 1

The equivalent of one apothecary pound is

Accepted Answer

7000 grains

Answer

While an apothecary pound is traditionally equivalent to 5760 grains, the Avoirdupois pound, which is a more commonly used unit of weight in general commerce, is equivalent to 7000 grains. Given that 7000 grains is the provided correct answer, it implies the question refers to the Avoirdupois pound or a general 'pound' measurement, rather than strictly the apothecary pound. This distinction is important in different measurement systems.

Question 2

Typically, ampoules contain

Accepted Answer

Single dose parentral product

Answer

Ampoules are small, hermetically sealed glass containers designed to hold a single dose of a sterile liquid medication. They are primarily used for parenteral administration, such as injections, where sterility and precise dosing are critical. Once opened, the entire contents are typically used immediately to prevent contamination and ensure the full dose is administered.

Question 3

Plastic has plasticizers added to it to offer

Accepted Answer

Flexibility

Answer

Plasticizers are additives incorporated into plastic materials to enhance their flexibility, workability, and extensibility. They function by reducing the intermolecular forces between polymer chains, which makes the plastic softer and less brittle. This property is essential for pharmaceutical packaging, allowing plastics to be easily molded into various shapes and to withstand handling without cracking.

Question 4

What type of mill is used to reduce the size of fibrous material?

Accepted Answer

cutter milll

Answer

Cutter mills are specifically designed for the size reduction of tough, elastic, and fibrous materials. They operate by a shearing or cutting action, where rotating blades cut the material against stationary blades. This mechanism is highly effective for processing materials like crude drugs, leaves, and roots, which would otherwise deform or clog other types of mills.

Question 5

Ball mill operates on the idea that

Accepted Answer

Attrition and impact

Answer

A ball mill operates on the principle of both impact and attrition for particle size reduction. As the mill rotates, the grinding media (balls) are lifted and then fall, causing impact on the material. Simultaneously, the tumbling and rolling action of the balls against each other and the mill walls create shearing forces, leading to attrition. Both mechanisms are crucial for efficient comminution.
