Dear videos we will discuss Histopathology MCQs today, which will help you in all type of competition exams in Laboratory. This video include 29 best and basic MCQs of Histopathology. Q1: Surgical Specimens after Removal Should be Placed in an Adequate quantity of fixative-----------as soon as possible. After surgery when tissue sample is send to laboratory it should be placed in an ideal fixative so which fixative is used from the following options? a) 10% Normal Saline b)10% Neutral buffered formalin c) 10% saline d) None of the above so the right answer is option b) 10% buffered formalin. 10% Neutral buffered formalin is an ideal fixative for tissue preservation and fixation with neutral pH. Q2: Which Buffers are used in Formaldehyde to make neutral buffered formalin? Options are: a) Sodium Acetate b) Boric Acid c) Acetic Acid d) Disodium Phosphate and Monosodium Phosphate The right option is d) Disodium Phosphate and Monosodium Phosphate Dear viewers i will put a link of my video about how to make 10% Neutral buffered formalin videos in eye button and description below, watch and learn how to make ideal fixative. Disodium Phosphate and Monosodium Phosphate is available in powder form and supply within these bottle and then mixed with formaldehyde and Normal saline or water to make 10% Neutral buffered formalin. Q3: For optimal fixation a piece of tissue should be immersed in at least ------------times its own volume of fixative. Option are: a) 30 time b) 60 times c) 10 times d) 100 time The right option is c) 10 times and in some books it is 10 to 20 times. Here you can see in picture the tissue is small and fixative volume is 10 to 20 times high because to fix tissue in a right way. big tissues are also placed in such a way to dip completely in fixative. Q4: If a rapid Frozen section is required the laboratory staff and Pathologist must be notified at least--------------hour before the time of the operation and preferably on the preceding day. Rapid frozen section is sometime required by doctors within 2 to 3 hours so from this they will identify either tumor is malignant or condition is inflammatory, this is carried out in a cryostate. so the options are: a) 24 hours b) 1 hour c) 10 hours d) 15 hours The right option is b) Laboratory staff and pathologist must be notified at least 1 hour before the time of operation. Rapid frozen section is sometime required by doctors within 2 to 3 hours so from this they will identify either tumor is malignant or benign or condition is inflammatory, there is no need of removal. this is carried out in a cryostate This is the cryostate inside with microtom and temperature inside is minus 25 to 30 c. Q5: A disposable syringe with----------------gauge needle can be used for Fine Needle Aspiration Biopsy. Options are: a) 10 to 12 b) 15 to 20 c) 21 to 25 d) 27 to 30 The right option is c) 21 to 25 gauge needle can be used for Fine Needle Aspiration Biopsy. Here you can see the syringe used for Fine Needle Aspiration biopsy with well designed Holder. Q6: Histological technique deals with the preparation of---------------for microscopic examination.Options are: a) Whole blood b) Tissue c) Serum d) None of the above right option is b) Tissue. Q7:-----------------is the process by which the constituents of the cells and tissues are fixed in a physical and partly also in a chemical state, so that they will withstand subsequent treatment with various reagents with a minimum loss of architecture. (Options are): a) Cutting b) Staining c) Clearing d) Fixation The right option is d) Fixation. Q8: Most fixatives act by denaturing or-------------------proteins, which then form a sponge or meshwork, tending to hold the other cell constituents.Options are: a) Heating b) Boiling c) Precipitating d) Melting Right option is c) Precipitating. Q9: Good--------------------------is the first most important factor for the production of satisfactory results in histopathology. Options are: a) Embedding b) Fixation c) Clearing d) Cutting The right option is: b) Fixation. Q10: Which of the following is the property of ideal fixative? Options are: a) It should not be expensive b) 10% neutral buffered formalin c) Prevent autolysis and bacterial decomposition d) It should be toxic The right option is c) Prevent autolysis and bacterial decomposition and a) It should not be expensive Q11: Zenker's Formal saline is a--------------------------fixative. Options are: a) Histochemical b) Cytological c) Short term d) Tissue Right option is d) Tissue. Q12: Routine 10% formal saline has an acidic pH, which results in formation of------------------------crystals in the tissues. Options are: a) Calcium Oxalate b) Amorphous Phosphate c) Haematin d) Magnessium Right option is c) Haematin. Haematin is the by product of Hemoglobin. Which make problems in microscopy of tissue. Q13: Tissues can be left in---------------------fixative for long period of time e.g., one year? Options are: a) 10% Normal Saline b) 10% Formalin c)10% Saline d) 10% Buffered formalin Right option is d) 10% buffered formalin also called 10% neutral buffered formalin. Q14: Rapidly freezing the tissue is an alternative to-----------------------------------? Options are: a) Fixation b) Clearing c) Dehydration d) Embedding Right option is a) Fixation. Q15: Using increasing strengths of alcohol-----------------------tissues. Options are: a) Breakdown b) Rehydrate c) Dehydrates d) Clear Right option is c) Dehydrate. Dehydration is the process in which water is removed from tissue by alcohol. Q16: Dehydration is helped by---------------------of the tissues. Options are: a) Agitation b) Using Formalin c) Heating d) Keeping in room temperature Right option is a) Agitation. Agitation manually helped removal of water from tissue when in alcohol after every 2 hours. Q17: During dehydration the water in the tissue has been replaced by------------------------------------? Options are: a) Alcohol b) Xylene c) Saline d) Acetic Acid right option is a) Alcohol. Q18: -----------------is a commonly used clearing Agent? Clearing agent is used in clearing step in which alcohol is removed from tissue by clearing agent. Options are: a) Chloroform b) Phosphate c) Xylene d) Carbol Fuchsin Right option is: C) Xylene and a) Chloroform. But most commonly use clearing agent is Xylene because chloroform is a bit expensive and toxic. Q19: In impregnation volume of wax should be about-------------------------times the volume of tissues. Options are: a) 10-12 b) 25-30 c) 40-50 d) 80-100 Right option is b) 25 to 30 times Q20: Types of Wax used routinely for impregnation is? Options are: a) Water soluble wax b) Gelatin c) Paraffin wax d) Celloidin Right option is: c) Paraffin Wax.

Q21: Dissection and examination of a dead body and its organs and structures are called--------------------------? Options are: a) Autopsy b) Cytology c) Biopsy d) Pathology Right option is: a) Autopsy. Q22: --------------------------is a medical and diagnostic procedure in which cells or tissues are removed from a patient and examined visually, usually with a microscope. Options are: a) Autopsy b) Surgery c) Endoscopy d) Biopsy Right option is: d) Biopsy. Q23: ----------------is the process of removal of the calcium salts from the specimen. Options are: a) Fixation b) Decalcification c) Dehydration d) Diffusion Right option is: b) Decalcification. Q24: -----------------------is used to preserve and support a stained section for light microscopy, it is mounted on a clear glass slide, and covered with a thin glass coverslip. Options are: a) Section Cutting b) Staining c) Impregnation d) Mounting Right option is: d) Mounting. Q25: -------------------stain is the commonest stain used in Histopathology? Options are: a) Sudan Black b) Haematoxylin and Eosin c) Giemsa d) Wright stain Right option is: b) Haematoxylin and Eosin Q26: Frozen tissue embedded in a freezing medium is cut on a microtome in a cooled machine called a------------------? Options are: a) Freezing box b) Cryostat c) Floatation box d) Base sledge Right option is: b) Cryostat. Q27: In----------------------impregnated tissues are placed in a mould with their labels and then fresh melted wax is poured in it and allowed to settle and solidify. Options are: a) Clearing b) Dehydration c) Embedding d) Fixation Right option is c) Embedding. Q28: The paraffin section flotation bath is designed to assist with the handling of paraffin wax samples in-------------------and pathology laboratories. Options are: a) Blood banking b) Histopathology c) Clinical Pathology d) Pharmacology Right option is: b) Histopathology. Q29: 10% buffered formalin has the advantage that----------------crystals not formed in tissue. Options are: a) Haematin b) Uric acid c) Calcium oxalate d) Amorphous urates Right option is a) Haematin. Dear viewers thank you so much for watching. This was some basic MCQs about Histopathology.
