The specimen should be fixed using formalin, as it preserves cellular morphology and structure by cross-linking proteins, thus preventing degradation. Alternatively, if molecular analysis is desired, optimal fixatives like paraformaldehyde may be preferred to maintain nucleic acids and proteins in a more intact state. The choice of fixative ultimately depends on the downstream applications, such as histology or molecular studies. Proper fixation is crucial for accurate diagnosis and research outcomes.

Which lenses does NOT affect the magnification of the specimen?
The lens that does not affect the magnification of the specimen is the ocular lens, or eyepiece, when it is used in conjunction with a fixed objective lens. While the ocular lens contributes to the total magnification when combined with the objective lens, it does not independently change the specimen's magnification. Instead, the objective lenses are primarily responsible for magnifying the specimen, with their varying focal lengths determining the level of magnification.
How identify specimen collection?
Specimen collection can be identified by labeling each specimen with patient information, date and time of collection, and type of specimen. The specimen should be collected using proper techniques, stored in appropriate containers, and transported to the lab in a timely manner to maintain specimen integrity. Accurate documentation of the entire collection process is important for proper identification.
When preparing a wet mount specimen for viewing it should be covered with?
When preparing a wet mount specimen for viewing, it should be covered with a coverslip. This thin piece of glass or plastic helps to flatten the specimen, prevent contamination, and protect the microscope's lenses. Care should be taken to lower the coverslip at an angle to avoid trapping air bubbles.
Which rock specimen should lead the student to choice 4 path a?
gneiss is the answer
Which part of a compound light microscope should a student adjust to allow more light to pass through a specimen?
The student should adjust the condenser to allow more light to pass through the specimen in a compound light microscope. By adjusting the condenser height or iris diaphragm, the amount of light reaching the specimen can be controlled for better visibility.
How should a smear specimen be fixed and why?
A smear specimen should be fixed by air-drying the sample or by heat-fixing the slide. This helps to preserve the cellular morphology and prevent degradation of the sample during staining and observation under a microscope. Fixation also improves the adherence of the cells to the slide, making it easier to analyze the sample.
When observing a slide should the specimen be on the top or bottom surface of the microscope?
The specimen should be placed on the top surface of the microscope slide. This allows the light to pass through the specimen from below and be magnified by the lenses in the microscope to form an image for observation.
What should you do if a specimen spills on your clothes?
If a specimen spills on your clothes, you should immediately remove the contaminated clothing and wash the affected area with soap and water. Be sure to follow any specific handling instructions for the type of specimen involved and seek medical advice if needed.
When viewing a specimen under the microscope you should always start with what?
When viewing a specimen under the microscope, you should always start with the lowest magnification objective lens. This allows you to locate and focus on the specimen before moving to higher magnifications for a closer look.
When focusing with a microscope do you always focus toward the specimen?
No, when using a microscope, you should focus away from the specimen initially by moving the objective lens upward, then slowly bring it down towards the specimen to avoid damaging the lens or the specimen.

How much feces should be collected for a specimen?
As much as necessary.
How identify specimen collection?
Specimen collection can be identified by labeling each specimen with patient information, date and time of collection, and type of specimen. The specimen should be collected using proper techniques, stored in appropriate containers, and transported to the lab in a timely manner to maintain specimen integrity. Accurate documentation of the entire collection process is important for proper identification.
Where should left out unlabeled specimen be left?
Left out unlabeled specimens should be placed in a designated area for unidentified samples, clearly marked to avoid confusion. It’s essential to document the specimen’s details, such as location and time of collection, to facilitate future identification. If possible, notify the relevant personnel or department about the unlabeled specimen for proper handling. Proper storage conditions should also be maintained to preserve the specimen's integrity.
Why the specimen should be dried before positioning and mounting?
Because it will change shape as it dries, so mounting it while it is wet would cause excessive stresses.
When preparing a wet mount specimen for viewing it should be covered with?
When preparing a wet mount specimen for viewing, it should be covered with a coverslip. This thin piece of glass or plastic helps to flatten the specimen, prevent contamination, and protect the microscope's lenses.

When should a urine specimen be collected for pregnancy test?
When you are at the doctors office.
