Question 1 Fixation

Question 1: Fixation

A histotechnologist receives a large fatty specimen for processing. Which factor most directly determines how well a 10 percent neutral buffered formalin fixative will penetrate the tissue?

Question 2 Tissue Processing

Question 2: Tissue Processing

During routine tissue processing, the dehydration step is performed before clearing. What is the purpose of the dehydration step using graded alcohols?

Question 3 Tissue Processing

Question 3: Tissue Processing

A histotechnologist needs a clearing agent that will replace alcohol and be miscible with paraffin during processing. Which agent is a traditional clearing agent used between dehydration and infiltration?

Question 4 Microtomy

Question 4: Microtomy

While cutting paraffin sections, a histotechnologist notices the ribbon is curving and the sections are compressed and thick and thin in alternating bands. Which microtomy problem is most consistent with thick and thin alternating sections?

Question 5 Staining

Question 5: Staining

In the routine hematoxylin and eosin stain, hematoxylin is applied first. What cellular component does hematoxylin primarily stain and what color does it produce?

Question 6 Special Stains

Question 6: Special Stains

A pathologist requests a special stain to demonstrate basement membranes and glycogen in a kidney biopsy. Which special stain is most appropriate for highlighting these carbohydrate-rich structures?

Question 7 Special Stains

Question 7: Special Stains

A histotechnologist must demonstrate amyloid deposits in a tissue section. After staining with the appropriate dye, the amyloid shows a characteristic apple-green birefringence. Which stain produces this finding when viewed under polarized light?

Question 8 Fixation

Question 8: Fixation

A specimen for routine histology is placed in 10 percent neutral buffered formalin. What is the recommended minimum ratio of fixative volume to tissue volume to ensure adequate fixation?

Question 9 Microtomy

Question 9: Microtomy

After cutting, paraffin ribbons are floated on a warm water bath before being picked up on slides. What is the primary purpose of the water bath in this step?

Question 10 Staining

Question 10: Staining

During hematoxylin and eosin staining, a histotechnologist performs a differentiation step with acid alcohol after applying hematoxylin. What does the differentiation step accomplish?

Question 11 Tissue Processing

Question 11: Tissue Processing

A batch of slides shows tissue that is brittle and crumbles during sectioning, and the processing log shows the tissue spent too long in the final paraffin baths. Which processing error best explains brittle, overhard tissue?

Question 12 Special Stains

Question 12: Special Stains

A pathologist suspects a fungal infection and requests a silver stain that will outline fungal organisms in black against a light green background. Which stain meets this description?

Question 13 Microtomy

Question 13: Microtomy

A histotechnologist is sectioning a paraffin block and the sections are not forming a continuous ribbon, instead separating into individual pieces. Which adjustment most directly promotes ribbon formation?

Question 14 Frozen Sections

Question 14: Frozen Sections

A frozen section is requested intraoperatively. The tissue is rapidly frozen in a cryostat. What is the main advantage of frozen section over routine paraffin processing in this setting?

Question 15 Fixation

Question 15: Fixation

A histotechnologist must select a fixative for a specimen that will undergo immunohistochemistry. Why is 10 percent neutral buffered formalin generally preferred over a fixative such as Bouin solution for many immunohistochemical applications?

Question 16 Staining

Question 16: Staining

A finished hematoxylin and eosin slide appears overall too pale, with both nuclei and cytoplasm weakly stained. The staining solutions were recently used many times. Which cause is most likely?

Question 17 Tissue Processing

Question 17: Tissue Processing

A histotechnologist embeds processed tissue into a paraffin block. During embedding, why is it important to correctly orient the tissue in the mold?

Question 18 Special Stains

Question 18: Special Stains

A histotechnologist performs a Masson trichrome stain on a liver biopsy to assess fibrosis. In a properly stained trichrome section, collagen typically appears which color?

Question 19 Laboratory Safety

Question 19: Laboratory Safety

A histology laboratory monitors employee exposure to formaldehyde vapors. Why is controlling formaldehyde exposure an important safety priority in the histology lab?

Question 20 Microtomy

Question 20: Microtomy

A histotechnologist faces a paraffin block before sectioning by trimming the surface with coarse cuts. What is the main purpose of facing or rough cutting the block?
