Hematology Techniques: Bone Marrow Aspiration and Biopsy - 4th Semester

1. What are some reasons why we would obtain a bone marrow sample?

-back pain

-common cold

-broken bone

Bone marrow samples are typically obtained for medical reasons related to blood disorders, cancer, or other diseases. Common cold, back pain, or broken bones do not typically require a bone marrow sample.

2. What supplies do you need to perform a bone marrow aspirate?

Bandages

Cotton swabs

Tweezers

Bone marrow aspirate procedure requires specific supplies such as slides, towel, clippers, sterile prep, blade, biopsy needle, sterile drape, sterile gloves, EDTA, syringe, and glue. Cotton swabs, tweezers, and bandages are not typically used in this procedure.

3. How should you prepare the site for a bone marrow aspirate?

Applying heat packs

Using dirty instruments

Skipping hand hygiene steps

-the area is shaved , - surgically prepped, - aseptic technique is used

Proper preparation of the site for a bone marrow aspirate is essential to prevent infections and ensure the procedure is conducted safely. Shaving the area, surgically prepping the site, and using aseptic techniques are crucial steps in minimizing the risk of complications.

4. Why do we prefer to have EDTA in our bone marrow syringe?

EDTA prevents bacterial contamination.

EDTA improves bone marrow viscosity.

EDTA helps in cell growth.

Bone marrow clots quickly

Having EDTA in the bone marrow syringe is preferred because it helps prevent the bone marrow from clotting quickly, allowing for easier handling and analysis.

5. How do you prepare EDTA for a bone marrow syringe?

Mix EDTA powder with water to create a solution for the syringe.

Put 1 ml of saline into a large EDTA tube and use it directly in the syringe.

Skip the EDTA step and directly transfer bone marrow to purple top tubes.

The correct method involves adding 1/2 ml of saline into a small EDTA tube and then transferring it to purple top tubes after coating the syringe. The other three options are incorrect as they deviate from the correct procedure.

6. What type of anesthetic do doctors normally use for a bone marrow aspirate?

It depends on the doctor, they will either do a local or general anesthetic

Epidural anesthesia

Nitrous oxide

Spinal anesthesia

Doctors may choose between local or general anesthetic based on the patient's medical history, preference, and the complexity of the procedure.

7. What type of needle is most often used for bone marrow biopsy?

A pediatric jamshidi bone marrow biopsy needle

A regular sewing needle.

A biopsy punch needle.

A knitting needle.

Bone marrow biopsy procedures require a specialized needle, such as the pediatric Jamshidi bone marrow biopsy needle, which is specifically designed for this medical procedure. Regular sewing needles, knitting needles, and biopsy punch needles are not suitable for bone marrow biopsy due to their design and intended use.

8. What size syringe is typically used for a bone marrow aspirate procedure?

A 20 ml syringe that is coated with citrate

A 10 ml syringe that is uncoated

A 12 ml syringe that is coated with EDTA

A 5 ml syringe that is coated with heparin

For a bone marrow aspirate procedure, a 12 ml syringe coated with EDTA is commonly used to prevent clotting and maintain cell integrity. Other syringe sizes and coatings may not be suitable for this specific procedure.
