Questions and Answers

1.

Why are transfusions given to a person?
- A.
  
  To increase the blood's ability to carry oxygen.
- B.
  
  To increase the amount of blood.
- C.
  
  To decrease the risk of bleeding.
- D.
  
  All of the above
Correct Answer
D. All of the above

Explanation
Transfusions are given to a person for multiple reasons. Firstly, they can help increase the blood's ability to carry oxygen, which is important for delivering oxygen to different parts of the body. Secondly, transfusions can increase the amount of blood in the body, which is beneficial in cases of severe blood loss or low blood volume. Lastly, transfusions can also help decrease the risk of bleeding by providing clotting factors and platelets. Therefore, all of the given options are valid reasons for giving transfusions to a person.

Which part of the blood can be transfused?
- A.
  
  RBCs
- B.
  
  Whole blood
- C.
  
  Platelets
- D.
  
  All of the above
Correct Answer
D. All of the above

Explanation
All of the above options can be transfused. Red blood cells (RBCs) are commonly transfused to treat anemia or blood loss. Whole blood transfusion is used in situations where multiple components of blood are needed, such as during surgery or in cases of severe bleeding. Platelets are transfused to help with blood clotting in individuals with low platelet counts. Therefore, all three options can be used for blood transfusion depending on the specific medical condition and requirements of the patient.

3.

What should be your minimum weight to donate blood?
- A.
  
  100 pound
- B.
  
  110 pound
- C.
  
  115 pound
- D.
  
  125 pound
Correct Answer
B. 110 pound

Explanation
To donate blood, the minimum weight requirement is usually set to ensure the donor's safety and well-being. In this case, the correct answer is 110 pounds, which suggests that individuals weighing less than this may not have enough body mass to safely donate blood. This weight requirement helps to prevent potential complications or health risks that may arise from donating blood, such as dizziness or fainting.

Rate this question:
4.

How often can a donor give blood?
- A.
  
  Every 3 months
- B.
  
  Every 2 months
- C.
  
  Every year
- D.
  
  At any time
Correct Answer
B. Every 2 months

Explanation
A donor can give blood every 2 months. This is because it takes approximately 8 weeks for the body to replenish the lost red blood cells after a donation. By waiting for this period, it ensures that the donor's body has enough time to recover and produce new blood cells before donating again. Giving blood too frequently can lead to a decrease in the donor's overall health and may cause anemia. Therefore, it is important to follow the recommended waiting period of 2 months between donations.

Rate this question:
5.

How much blood is mostly donated at a time?
- A.
  
  1 pint
- B.
  
  2 pints
- C.
  
  1 quart
- D.
  
  2 quarts
Correct Answer
A. 1 pint

Explanation
The correct answer is 1 pint. When donating blood, typically 1 pint (or 473 mL) of blood is collected from the donor. This amount is considered safe and does not pose any significant health risks to the donor. It is important to note that the donated blood is then processed and separated into its components, such as red blood cells, platelets, and plasma, which can be used to help multiple patients in need.

Rate this question:
6.

What are the common risks involved in donating blood?
- A.
  
  Bacterial infection
- B.
  
  Low blood pressure
- C.
  
  Contract common viruses
- D.
  
  None of the above
Correct Answer
D. None of the above

Explanation
The correct answer is "None of the above." The question asks about the common risks involved in donating blood, and none of the options provided are accurate. Common risks of donating blood include bruising or bleeding at the needle insertion site, lightheadedness or dizziness, and fainting. However, the options listed in the question do not align with these common risks.

  HIV
- B.

- C.

- D.
  
  Option1 & 2
Correct Answer
D. Option1 & 2

Explanation
The correct answer is Option 1 & 2. HIV and Viral Hepatitis are diseases that are screened in donated blood. Screening for these diseases is important to ensure the safety of the blood supply and prevent transmission of these infections to recipients. Diabetes, however, is not a disease that is screened in donated blood.
