    Viscous liquids such as glycerin or propylene glycol will require approximately _____ to transfer out of a single volume pipette.

    • 3 minutes

    • 5 minutes

    • 10 minutes

    • 15 minutes

    Correct Answer
    A. 3 minutes
    Explanation
    Viscous liquids such as glycerin or propylene glycol have a higher resistance to flow compared to less viscous liquids. This means that it takes more time for these liquids to transfer out of a pipette. Therefore, it would require approximately 3 minutes for a viscous liquid to transfer out of a single volume pipette.

    Which type of syringe is used to administer a dose of liquid medication to a patient?

    • Hypodermic with Luer-Lok

    • Oral syringe

    • Hypodermic with SLip-Tip

    • Adapt-A-Cap

    Correct Answer
    A. Oral syringe
    Explanation
    An oral syringe is used to administer a dose of liquid medication to a patient. This type of syringe is specifically designed for oral use and has a long, narrow tip that allows for easy and accurate dosage measurement. Unlike hypodermic syringes, which are used for injections, oral syringes are meant to be used by the patient to take medication orally. The Luer-Lok and Slip-Tip syringes mentioned in the options are types of hypodermic syringes used for injections, while Adapt-A-Cap is not a type of syringe at all.

    ______ is the technique used to mix two powders of unequal quantity.

    • Volumetric dilution

    • Volumetric emulsification

    • Geometric emulsification

    • Geometric dilution

    Correct Answer
    A. Geometric dilution
    Explanation
    Geometric dilution is the technique used to mix two powders of unequal quantity. In this technique, a small amount of the more potent powder is mixed with an equal amount of the less potent powder. This mixture is then combined with an equal amount of the less potent powder again, and the process is repeated until the desired quantity is achieved. This method ensures that the powders are evenly distributed throughout the mixture, resulting in a uniform and accurate blend.

    The fine grinding of powder is called:

    • Melting

    • Trituration

    • Levigation

    • Suspension

    Correct Answer
    A. Trituration
    Explanation
    Trituration refers to the process of grinding or pulverizing substances into fine powder form. It involves the use of a mortar and pestle or other grinding tools to break down the particles into smaller sizes. This technique is commonly used in pharmacy and laboratory settings to prepare powdered medications or mixtures. Therefore, trituration is the appropriate term for the fine grinding of powder.

    Solutions contain:

    • Molecular size particles

    • Particles greater than 0.1 micrometer

    • Oil, water, and emulsifiers

    • Hydrated macromolecules that restrict solvent flow

    Correct Answer
    A. Molecular size particles
    Explanation
    The correct answer is "molecular size particles" because solutions typically contain particles that are smaller than 0.1 micrometers in size. These particles can be molecules or ions dissolved in a solvent. The other options mentioned, such as particles greater than 0.1 micrometer, oil, water, and emulsifiers, and hydrated macromolecules that restrict solvent flow, do not accurately describe the general composition of solutions.

    Rate this question:

  • 49. 

    The USP/NF gives "relative terms of solubility," if a drug is soluble, how many parts of solvent are required for one part of the drug?

    • 1-10

    • 1-30

    • 30-100

    • 100-1000

    Correct Answer
    A. 1-30
    Explanation
    The USP/NF states that if a drug is soluble, it requires 1-30 parts of solvent for one part of the drug. This means that the drug can dissolve in a relatively small amount of solvent, indicating good solubility.
