Sealed glass containers with an elongated neck
- A.
Gauge
- B.
Ampules
- C.
CSP
- D.
Vial
Correct Answer
B. AmpulesExplanation
Ampules are sealed glass containers with an elongated neck. They are commonly used in the pharmaceutical industry to store and preserve medications or other substances. Ampules are designed to be airtight and provide a secure and sterile environment for the contents inside. Unlike vials, which typically have a rubber stopper or a screw cap, ampules are sealed by melting the glass neck after filling. This ensures that the contents remain uncontaminated and protected from external factors such as air or moisture.Rate this question:

- C.
Compounded sterile preparation (CSP)
- D.
Gauge
Correct Answer
C. Compounded sterile preparation (CSP)Explanation
A compounded sterile preparation (CSP) refers to a dosage form that is prepared in a sterile environment and is intended to be administered parenterally, meaning it is injected into the body. This term is used to describe medications that are prepared by a pharmacist or other healthcare professional in a sterile compounding facility. The term "compounded" indicates that the medication is customized or tailored to meet the specific needs of an individual patient. The term "sterile" indicates that the medication is free from any microorganisms that could cause infection. Therefore, a compounded sterile preparation (CSP) is the correct answer as it best describes a dosage form that is both sterile and intended for parenteral administration.Rate this question:

When a needle damages the rubber closure of a parenteral container causing fragments to fall into the container
- A.
Coring
- B.
Syringe ability
- C.
Final filter
- D.
Bevel
Correct Answer
A. CoringExplanation
Coring refers to the situation when a needle damages the rubber closure of a parenteral container, causing fragments to fall into the container. This can occur when the needle pierces the rubber closure and instead of creating a clean hole, it removes a small piece of rubber, which then falls into the container. This can be a concern as the rubber fragments can contaminate the contents of the container, potentially leading to adverse effects when administered to patients. Therefore, coring is an important consideration in maintaining the integrity and safety of parenteral containers.Rate this question:

- A.
Depth filter
- B.
Web filter
- C.
Membrane filter
- D.
Final filter
Correct Answer
A. Depth filterExplanation
A depth filter is the correct answer because it is designed to filter solutions being drawn into or out of a syringe, but not both ways in the same procedure. Depth filters are typically composed of a thick layer of fibrous material that allows for the passage of fluid in one direction while trapping particles and impurities. This makes them suitable for applications where a unidirectional flow is required, such as in syringe filtration processes.Rate this question:

When a solution has an osmolarity equivalent to that of blood
- A.
Hypotonic
- B.
Isotonic
- C.
Hypertoni
- D.
Therapeutic
Correct Answer
B. IsotonicExplanation
An isotonic solution has the same osmolarity as blood, which means it has the same concentration of solutes as blood. This is important because when a solution is isotonic, it does not cause water to move into or out of cells. It maintains the balance of fluids inside and outside of cells, preventing them from swelling or shrinking. This is why an isotonic solution is often used in medical settings, such as for intravenous fluid replacement, to ensure that it is compatible with the body's cells and does not cause any adverse effects.Rate this question:

- C.
Isotonic
- D.
Tonic
Correct Answer
A. HypotonicExplanation
A solution that has a lesser osmolarity than that of blood is considered hypotonic. In a hypotonic solution, there is a lower concentration of solutes compared to blood. This causes water to move into the cells through osmosis, resulting in the cells swelling or potentially bursting.Rate this question:

- D.
Isotonic
Correct Answer
C. HypertonicExplanation
A solution is considered hypertonic when it has a greater osmolarity than that of blood. Osmolarity refers to the concentration of solute particles in a solution. When a hypertonic solution is introduced, it creates a higher osmotic pressure compared to blood. This difference in osmotic pressure causes water molecules to move out of the blood cells through osmosis, resulting in cell shrinkage or dehydration.Rate this question:

Correct Answer
C. LyopHilizedExplanation
Lyophilized refers to a process of freeze-drying a substance, typically a pharmaceutical or biological product, to remove the water content and preserve it in a stable and solid form. This technique involves freezing the substance and then subjecting it to a vacuum, causing the frozen water to sublimate directly from solid to gas, leaving behind a dry and powdery product. Therefore, the term "lyophilized" is the most appropriate and relevant choice among the given options.Rate this question:

The action in which a drug in a higher concentration solution passes through a permeable membrane to a lower concentration solution
- A.
Osmosis
- B.
Membrane filiter
- C.
Isotonic
- D.
Final filter
Correct Answer
A. OsmosisExplanation
Osmosis is the correct answer because it refers to the process in which a drug, or any solute, moves from a higher concentration solution to a lower concentration solution through a permeable membrane. This movement occurs due to the natural tendency of solutes to equalize their concentrations on both sides of the membrane. Osmosis is a vital process in biological systems, as it helps maintain the balance of water and solutes within cells and across cell membranes.Rate this question:

C. Irrigation solutionExplanation
An irrigation solution is a large volume splash solution used during surgical or urologic procedures to bathe and moisten body tissues. It helps to clean and flush out the area being operated on, removing debris and preventing infection. This solution is typically isotonic, meaning it has the same concentration of solutes as the body's cells, to avoid any adverse effects on the tissues. Osmotic pressure and osmosis are not directly related to the concept of an irrigation solution.Rate this question:

BSC
Correct Answer
C. Laminar flowExplanation
Laminar flow refers to the smooth and continuous movement of a fluid in a straight line, with layers of the fluid flowing parallel to each other. In this type of flow, there is minimal mixing or turbulence, and the fluid particles move at a uniform rate. The term "laminar" comes from the Latin word "lamina," which means layer, indicating the organized and ordered movement of the fluid. Therefore, the given answer of "laminar flow" accurately describes the concept of continuous movement at a uniform rate in one direction.Rate this question:

Correct Answer
C. Produce feverExplanation
Pyrogens are substances that can induce fever in the body. They are typically produced by bacteria, viruses, or other microorganisms. When pyrogens enter the body, they stimulate the release of certain chemicals that raise the body's temperature, resulting in fever. Pyrogens are not water soluble, meaning they do not dissolve in water. They can also be present in parenteral solutions, which are solutions administered directly into the bloodstream. Additionally, pyrogens can be removed from solutions through filtration processes.Rate this question:
