What does normal plasma look like?
Explanation
Normal plasma is the liquid component of blood that is free from cells and clotting factors. It is typically a clear, light yellow color. This color is due to the presence of proteins, such as albumin, and other substances dissolved in the plasma. The yellow color becomes more pronounced when the plasma is concentrated, such as during dehydration, while a pale or watery appearance may indicate dilution. Monitoring the color of plasma can provide valuable information about a person's hydration status and overall health.Rate this question:
- 6.
Plasma is _____%water ______%protein ______%dissolved Solids

Hemoguard is specifically designed to preserve the integrity of the blood sample and maintain its stability for laboratory testing purposes.Rate this question:
- 14.
What does Lipemic or chylous plasma look like?
Explanation
Lipemic or chylous plasma appears as a cloudy white color. This is due to the presence of high levels of lipids or fats in the plasma, which causes it to become opaque and cloudy. The cloudy appearance is a result of the scattering of light by the lipid particles suspended in the plasma. This can occur in conditions such as hyperlipidemia or when there is an increased amount of chylomicrons, which are lipoprotein particles that transport dietary fats.Rate this question:
- 15.
What does Icteric or jaundiced plasma look like?
Explanation
Icteric or jaundiced plasma appears dark yellow or yellow brown. Jaundice is a condition characterized by the yellowing of the skin and eyes, caused by a buildup of bilirubin in the blood. Bilirubin is a yellow pigment produced by the breakdown of red blood cells. When there is an excessive amount of bilirubin in the blood, it can give a yellowish color to the plasma, which is the liquid component of the blood. Therefore, dark yellow or yellow brown is the correct description for icteric or jaundiced plasma.Rate this question:
- 16.
What does hemolyzed plasma look like??
Explanation
Hemolyzed plasma appears as a clear red color. Hemolysis refers to the rupture or destruction of red blood cells, causing the release of hemoglobin into the plasma. The presence of hemoglobin gives the plasma a red color, which is still clear in appearance.Rate this question:
- 17.
Where are erythrocytes produced?
Explanation
Erythrocytes, also known as red blood cells, are produced in the bone marrow, which is found in flat bones as well as in the red marrow of other bones. The bone marrow is responsible for the production of all blood cells, including erythrocytes. These cells play a crucial role in transporting oxygen to different parts of the body.Rate this question:
- 18.
What is the life span of erythrocytes in dogs and cats?
Explanation
Erythrocytes, or red blood cells, have a lifespan of approximately 100 days in both dogs and cats. These cells play a crucial role in transporting oxygen throughout the body. Over time, they become old and less efficient, and are eventually removed from circulation by the spleen and liver. The body constantly produces new erythrocytes to replace the old ones, maintaining a healthy balance. This 100-day lifespan is an average and can vary slightly depending on the individual animal's health and other factors.Rate this question:
- 19.
What is the life span of erythrocytes in horses and cows?
Explanation
The life span of erythrocytes in horses and cows is 140 days. Erythrocytes, also known as red blood cells, are responsible for carrying oxygen to tissues and removing carbon dioxide. In horses and cows, these cells have a relatively long life span compared to other animals. This extended life span allows them to efficiently perform their vital functions within the circulatory system for a longer period of time.Rate this question:
- 20.
Where are thrombocytes formed?
Explanation
Thrombocytes, also known as platelets, are formed in the red bone marrow. Red bone marrow is a soft tissue found in the spongy part of bones, and it is responsible for the production of various blood cells, including thrombocytes. These platelets play a crucial role in blood clotting, preventing excessive bleeding, and promoting the repair of damaged blood vessels. Therefore, the correct answer is red bone marrow.Rate this question:

Three causes for increased PCV
Correct Answer
Dehydration, polycythemia, High altitudesExplanation
Increased PCV (Packed Cell Volume) refers to an elevation in the proportion of red blood cells in the blood. Dehydration can cause an increase in PCV as the volume of plasma decreases, leading to a relative increase in the number of red blood cells. Polycythemia, a condition characterized by an excessive production of red blood cells, can also result in increased PCV. High altitudes can cause an increase in PCV due to the reduced availability of oxygen, leading to the body producing more red blood cells to compensate for the lower oxygen levels.Rate this question:
- 25.
Three causes for decreased PCV
Correct Answer
Anemia, Hemolysis, Bleeding disordersExplanation
The correct answer is anemia, hemolysis, and bleeding disorders. Anemia refers to a decrease in the number of red blood cells or the amount of hemoglobin in the blood, which can lead to a decreased PCV (packed cell volume). Hemolysis is the breakdown of red blood cells, which also results in a decreased PCV. Bleeding disorders can cause excessive blood loss, leading to a decrease in the PCV. These three conditions are known causes of decreased PCV.Rate this question:
- 26.
4 Technical errors that cause altered PCV results
Correct Answer
Improper mixing, Improper spinning, leaking tubes, HemolysisExplanation
The answer provided lists four technical errors that can cause altered PCV (Packed Cell Volume) results. Improper mixing refers to not adequately mixing the blood sample before testing, which can lead to inaccurate results. Improper spinning refers to not centrifuging the blood sample at the correct speed and duration, resulting in incorrect separation of the components. Leaking tubes can cause loss of blood sample or contamination, affecting the accuracy of the PCV measurement. Hemolysis, the breakdown of red blood cells, can also impact PCV results by altering the concentration of red blood cells in the sample.Rate this question:
- 27.
What is the hemoglobin normal for the horse and dog?
Correct Answer
15 g/dlExplanation
The normal hemoglobin level for both horses and dogs is 15 g/dl. Hemoglobin is a protein found in red blood cells that carries oxygen throughout the body. This level indicates the amount of hemoglobin present in a deciliter of blood.

A level of 15 g/dl is considered normal for both horses and dogs.Rate this question:
- 28.
What is the hemoglobin normal for the cat and cow?
Correct Answer
12 g/dlExplanation
The hemoglobin normal for both cats and cows is 12 g/dl. This is the typical range of hemoglobin levels found in these animals. Hemoglobin is a protein in red blood cells that carries oxygen throughout the body. Having a hemoglobin level of 12 g/dl indicates that the cat or cow has a healthy amount of this protein in their blood, ensuring proper oxygen delivery to their tissues and organs.Rate this question:
- 29.
Blood + _______reagent = Cyanmethemoglobin
Correct Answer
DrabkinsExplanation
Drabkins reagent is a solution used in laboratory tests to measure the concentration of hemoglobin in blood. When mixed with blood, Drabkins reagent reacts with hemoglobin to form a stable compound called cyanmethemoglobin. This compound is then measured spectrophotometrically to determine the hemoglobin concentration in the blood sample. Therefore, the correct answer is Drabkins, as it is the specific reagent required to produce cyanmethemoglobin.Rate this question:
