The liquid portion of an antocoagulated blood specimen is called:
- A.
  
  Plasma
- B.
  
  Serum
- C.
  
  Cellular components
- D.
  
  Buffy coat
Correct Answer
A. Plasma

Explanation
Plasma is the correct answer because it is the liquid portion of a blood specimen that is obtained after the blood has been anticoagulated.

After eating too much fatty foods and not fasting, we should expect the patient's serum to appear:
- A.
  
  Lipemic
- B.
  
  Bright pink
- C.
  
  Pale yellow
- D.
  
  Bright red
Correct Answer
A. Lipemic

Explanation
After eating too much fatty foods and not fasting, the patient's serum is expected to appear lipemic. Lipemia refers to the presence of an abnormally high level of lipids (fats) in the blood, which can cause the serum to appear cloudy or milky. This is commonly seen after consuming a high-fat meal, as the body releases chylomicrons (lipoproteins that transport dietary fats) into the bloodstream. These chylomicrons increase the lipid content of the serum, resulting in a lipemic appearance.

Prolonged tourniquet application will cause:
- A.
  
  Hemolysis
- B.
  
  Hematoma
- C.
  
  Hemoconcentration
- D.
  
  All of the above
Correct Answer
C. Hemoconcentration

Explanation
Prolonged tourniquet application can cause hemoconcentration. When a tourniquet is applied for an extended period of time, it restricts blood flow to the area below the tourniquet. This can lead to an increase in the concentration of red blood cells and other components of the blood in that area, resulting in hemoconcentration. Hemolysis refers to the breakdown of red blood cells, which is not directly caused by tourniquet application. Hematoma refers to the collection of blood outside of blood vessels, which can occur as a result of trauma or injury, but is not directly caused by tourniquet application.

When performing a venipuncture, the best angle for needle insertion is:
- A.
  
  15-30 Degress
- B.
  
  30 degrees
- C.
  
  30-45 degrees
- D.
  
  5-15 degress
Correct Answer
A. 15-30 Degress

Explanation
The best angle for needle insertion during a venipuncture is 15-30 degrees. This angle allows for proper access to the vein while minimizing the risk of puncturing through the vein or causing discomfort to the patient. A shallower angle (5-15 degrees) may result in the needle not entering the vein properly, while a steeper angle (30-45 degrees) may increase the risk of puncturing through the vein or causing hematoma formation. Therefore, the ideal angle for needle insertion is 15-30 degrees.

To cleanse the venipuncture site, we must use:
- A.
  
  A side to side motion
- B.
  
  A circular concentric motion
- C.
  
  Anyway you want
- D.
  
  None of the above
Correct Answer
B. A circular concentric motion

Explanation
To cleanse the venipuncture site, a circular concentric motion is recommended. This motion helps to effectively clean the area by starting at the center and moving outward in a circular motion. This ensures that all areas of the site are thoroughly cleansed and reduces the risk of contamination. Using a side to side motion or any other random motion may not provide the same level of cleanliness and may increase the risk of infection. Therefore, a circular concentric motion is the preferred method for cleansing the venipuncture site.
