What is the total magnification achieved with a compound microscope?
- A.
Magnification of objective lens

Magnification of ocular lens
- C.
Magnification of ocular lens added to the magnification of the objective lens
- D.

Correct Answer
D. Magnification of ocular lens multiplied by the magnification of the objectiveExplanation
To calculate the total magnification achieved with a compound microscope, the magnification of the ocular lens is multiplied by the magnification of the objective lens. For example, if viewing a sample with the 40x objective, the total magnification would be calculated as follows: a 10X ocular lens used with a 40X objective lens, the total magnification is 400X (10 x 40).Rate this question:

What is the maximum resolving power seen with a compound microscope?
- A.
2 millimeters
- B.
2 micrometers
- C.
2 angstroms
Correct Answer
B. 2 micrometersExplanation
Resolving power is the ability to see two things as discrete images. With normal vision, there is a resolving power of about of 100 micrometers. A compound microscope has a resolving power of approximately .2 micrometers. In other words, two marks .2 micrometers apart can be seen as two distinct entities. Any closer than this, they are perceived as one object.Rate this question:

During the preparation of a routine H&E slide, what step occurs after the tissue is preserved?
- A.
Fixation
- B.
Embedding in paraffin
- C.
Staining
- D.
Slicing
- E.
Dehydration
Correct Answer
E. DehydrationExplanation
After the tissue is preserved, the next step in the preparation of a routine H&E slide is dehydration. Dehydration involves removing water from the tissue by gradually increasing the concentration of alcohol. This step is necessary to prepare the tissue for embedding in paraffin, which is the subsequent step in the process. Dehydration helps to remove water from the tissue, making it easier to impregnate the tissue with paraffin wax.Rate this question:

Slicing
- E.
Dehydration
Correct Answer
A. FixationExplanation
During the preparation of a routine H&E slide, the tissue is preserved through fixation. Fixation involves treating the tissue with a chemical solution, such as formalin, to prevent decay and preserve the cellular structure. This process helps to maintain the integrity of the tissue and prevent any changes or degradation that may occur during subsequent steps of the slide preparation. Fixation is an essential step in histology as it allows for accurate examination and analysis of the tissue under a microscope.Rate this question:

Fixation
- B.
Embedding in paraffin
- C.
Staining
- D.
Slicing
- E.
Dehydration
Correct Answer
C. StainingExplanation
There are several steps in the preparation of a slide for microscopic examination. First, the tissue is "fixed" with formalin. This preserves it. After the tissue is fixed, it is dehydrated (dehydration will occur twice during slide preparation). The tissue sample is then embedded in paraffin. This forms a solid block, so that it can be placed in a microtome. It is then thinly sliced using a microtome. A thin slice of the specimen is then placed on a slide. The paraffin is removed by dissolving it with a chemical. The tissue is then rehydrated. In order to view the tissue, it is stained. After it is stained, it is again dehydrated. A coverslip is the mounted on top of it. The specimen is then ready for viewing.Rate this question:

Which of the following would be best suited to visualize reticular fibers?
- A.
Wright's stain
- B.
Hematoxylin and eosin stain
- C.
Sudan stain
- D.
Silver impregnation
- E.
Masson's trichrome stain
Correct Answer
D. Silver impregnationExplanation
Silver impregnation is the best suited method to visualize reticular fibers. Reticular fibers are delicate and fine fibers that form a network within connective tissues. They are difficult to visualize using routine staining methods. Silver impregnation techniques involve the deposition of silver salts onto the reticular fibers, making them visible under a microscope. This staining method specifically targets and highlights reticular fibers, allowing for their clear visualization and study.Rate this question:

- E.
Masson's trichrome stain
Correct Answer
C. Sudan stainExplanation
Sudan stain would be best suited to visualize lipids because it is a specific stain that binds to lipids, making them visible under a microscope. This stain is commonly used in histology to identify and study lipid-rich tissues or structures, such as adipose tissue. It allows for the visualization and differentiation of lipids based on their color or intensity of staining, providing valuable information about their distribution and composition.Rate this question:

During the preparation of a routine H&E slide, what allows the tissue to hold its form?
- A.
Fixation
- B.
Embedding in paraffin
- C.
Staining
- D.
Slicing
- E.
Dehydration
Correct Answer
B. Embedding in paraffinExplanation
Embedding in paraffin allows the tissue to hold its form during the preparation of a routine H&E slide. Paraffin embedding involves immersing the tissue in liquid paraffin, which then solidifies, providing support and preserving the tissue structure. This process helps to maintain the integrity of the tissue and allows for thin and consistent slicing of the sample for microscopic examination. Fixation, staining, and dehydration are important steps in the slide preparation process, but they do not directly contribute to the tissue's ability to hold its form.Rate this question:

Thionine
Correct Answer
D. EosinExplanation
Eosin is an acid dye. It will bind to and stain basic structures (or negatively charged structures), such as cationic amino groups on proteins. It stains them pink. Cytoplasm, muscle, connective tissue, and decalcified bone matrix all stain pink with eosin. "H&E" stand for hematoxylin and eosin. Hematoxylin and eosin stain is used for routine tissue preparation frequently.

Correct Answer
A. Wright's stainExplanation
Wright's stain would be best suited for peripheral blood smears because it is a combination of eosin and methylene blue dyes that allows for differentiation of different types of blood cells. It stains the cytoplasm of red blood cells pink, the nuclei of white blood cells purple, and the granules in certain white blood cells blue or purple. This staining pattern allows for easy identification and differentiation of different blood cell types under a microscope.Rate this question:
