OSMT (Ontario Society of Medical Technologists) Practice Exam

What is the recommended practice when embedding multiple tissue samples in one mold?

1. a. the pieces of tissue should touch each other

2. b. there should be a space between the pieces of tissue

3. c. the knife should approach the tissues on a slant

4. d. the angle of clearance should be increased

The correct answer is: a. the pieces of tissue should touch each other

When embedding multiple tissue samples in one mold, the recommended practice is for the pieces of tissue to touch each other. This is important to ensure that when the tissue block is sectioned, each sample will be consistently cut across all sections. If there is a space between the pieces of tissue, it may lead to inconsistencies in the sectioning process, resulting in varying thicknesses of tissue sections and potentially impacting the quality of the samples for analysis. Option B is incorrect as it goes against the recommended practice of having the pieces of tissue touch each other. Option C mentioning the knife approaching the tissues on a slant is not directly related to the embedding of multiple tissue samples in one mold. Option D referring to increasing the angle of clearance is also unrelated to the specific recommended practice of ensuring the pieces of tissue touch each other when embedding multiple samples in one mold.
