The moment a vein isn’t visible, I usually apply a hot washcloth to the area I want to infuse for several minutes, which will make the vein visible. If it still isn’t showing, I swing the patient’s arm around several times as the centrifugal force will make blood enter the arm, dilating the vein, hence making them visible. Nonetheless, if both steps fail, I call the nurse in charge to make other arrangements for the patient.

Furthermore, I am a team player and work efficiently with the medical staff to deliver the highest standard of care to patients.
5. What is a Vacutainer Blood Collection Tube?
The interviewer wants to assess if you are familiar with a vacutainer blood collection tube
Tip #1: Define the vacutainer blood collection tube
Tip #2: Demonstrate how it works
Vacutainer tubes have a double-pointed needle, a plastic holder, and a sequel of vacuum tubes with rubber stoppers of different colors. The color symbolizes the type of additive. Using a Vacutainer is the best way of collecting blood for analysis. It’s easy and safe to use since the blood sample will go directly into the test tube instead of collecting blood first and transferring it to the system.
6. What is Thrombin Time?
The interviewer wants to test your knowledge concerning thrombin time.
Tip #1: Explain the meaning of thrombin time
Tip #2: Show that you are aware of the thrombin time
Thrombin time evaluates the part of a hemostatic process where the conversion of soluble fibrinogens to fibrin threads takes place. It considers the time required for a fibrin clot to form following a standard amount of thrombin to plasma.

Tip #2: Highlight all the measures you will put in place
When I fail to obtain blood after puncturing, I change the needle’s position and move it forward or backward if it has penetrated too far. After that, I set the hand at the correct angle; the bevel may be against the vein wall. I loosen the belt; it may be preventing the blood flow. Then, I use another tube and re-anchor the vein since the vein sometimes slips away from the needlepoint. If all these fail, then I will look for another alternative.
8. Explain How You Collect Blood From Babies?
The interviewer wants to know how you obtain blood from babies.
Tip #1: Demonstrate the technique you use to get blood from babies
Tip #2: Be eloquent and straight to the point
Infants are very delicate; thus, collecting blood should be done in a very creative manner. I collect blood from the heel area or foot. I pre-warm the infant’s foot between 35-40 degrees for about five minutes. The warmth is significant in increasing the blood flow and helps detect the capillaries easily. After that, I puncture across the heel print lines and wipe away the first drop of blood with dry cotton wool and collect the sample from the second drop of blood. I then apply the sterile solution to the puncture area to stop bleeding.
9. What Are the Various Color Tubes Used in Phlebotomy, and What Does it Indicate?

The blood collection tube has a different color top, which symbolizes the tests. The Golden Top is for serology and immunology testing. However, it uses various chemicals to test. The red top is also for immunology and serology testing. Blacktop for testing Westergren sedimentation rate. Orange top for testing STAT serum chemistries, Browntop for serum lead determination, yellow, blacktop for microbiological testing, light gray top for blood sugar testing, light blue top for coagulation tests, and dark green top for whole blood testing using EDTA.
10. What Are The Possible Risk Associated With Arterial Sampling in Neonatal?
The interviewer wants to know the threat which arterial sampling in Neonatal may pose.
Tip #1: Demonstrate all the risk which may occur during arterial sampling in neonatal
Tip #2: Explain the threats in details
Arterial sampling is a precarious situation, especially in neonatal.

I first tie the belt around the upper arm and about 2-3 inches above the venipuncture area. I confirm the belt doesn’t lose the hand’s grip; since this will exert pressure on the vein and make it show clearly. I palpate the vein and locate the best area to collect blood. I then apply disinfectant to sterile the collection site, insert the syringe with the correct angle, draw blood out, and put it in a sample tube. After all this, I loosen the belt from the patient’s arm.
13. How is a Vacutainer Needle Different From Normal Syringe Needle?
The interviewer wants to know the main differences between a regular syringe and a vacutainer needle.
Tip #1: Highlight the differences between the two needles
Tip #2: Give the use of each needle
A Vacutainer needle is dual-ended, meaning it is sharp on both ends. You draw blood by holding the hand in place; the vacutainer is pressed against the other end of the needle to punch the seal. The negative pressure equalization causes the blood to flow into the container, while the ordinary syringe has one sharp end. You draw blood by pulling the plunger that creates negative pressure between the needle and plunger head.
14. What are the Various Sizes of Vacutainer Tubes Available?
The employer wants to know the various sizes of vacutainer tubes that are present
Tip #1: Demonstrate the multiple dimensions of vacutainer tubes
Tip #2: Show confidence and be straight to the point

The tests I carry out to check the kidney’s state include; Creatine test, where a high level of creatine in urine indicates the kidney won’t be running correctly. The other check is the urea test, and a high level of urea in the urine shows the kidney won’t be operating Estimated Glomerular Filtration Rate (eGFR). Lastly, dissolved salts such as potassium, sodium, chloride, and bicarbonates are electrolyte, and any alteration inside the level of an electrolyte can result from kidney dysfunction.
17. What is the HIV Test Window Period?
The interviewer wants to know about the window period in the HIV test.
Tip #1: Explain the HIV test window period
Tip #2: Concentrate only on the relevant facts about the window period
HIV test Window duration is the time c program language length between the unique infection with the HIV and the arrival of detectable antibodies to the virus. The window length is between 14-21 days, while in some, it may last for 12 weeks. Therefore, the HIV patient’s blood sample will show no sign of HIV contamination if he/she is in the window stage until he passes the window stage. After this, the virus will be detectable in the blood sample.
