Questions and Answers
- 1.
Which of the following is the purpose of warming infants prior to a heel puncture?
- A.
To soften
- B.
To increase flow of blood
- C.
To decrease flow of blood
- D.
All of the above
Correct Answer
B. To increase flow of bloodExplanation
Warming infants prior to a heel puncture is done to increase the flow of blood. This is because warming the area helps to dilate the blood vessels, making it easier to obtain a blood sample. Increased blood flow ensures that an adequate amount of blood can be collected for testing purposes.Rate this question:

Which of the following statement is true?
- A.
A tourniquet is very essential to effectively perform a finger stick
- B.
A syringe isn't needed for a finger stick
- C.
A lancet is very crucial in performing a finger stick
- D.
B & C
Correct Answer
D. B & CExplanation
The statement that a syringe isn't needed for a finger stick and that a lancet is very crucial in performing a finger stick is true. A finger stick is a procedure used to obtain a small blood sample for testing purposes. A tourniquet is not essential for a finger stick, as it is primarily used to restrict blood flow during venipuncture (drawing blood from a vein). Instead, a lancet, which is a small, sharp instrument, is necessary to puncture the skin and create a small incision for blood collection during a finger stick.Rate this question:

Capillary tubes are responsible for collecting which of the following?
- A.
Water
- B.
Food
- C.
Blood
- D.
Waste
Correct Answer
C. BloodExplanation
Capillary tubes are responsible for collecting blood. Capillaries are the smallest blood vessels in the body and they connect the arterioles to the venules. They have thin walls that allow for the exchange of oxygen, nutrients, and waste products between the blood and the surrounding tissues. Capillaries collect blood from the arterioles and deliver it to the venules, which then transport it back to the heart. Therefore, capillary tubes play a crucial role in the circulation of blood throughout the body.Rate this question:

Why is it not encouraged to make use of the radial artery for arterial puncture?
- A.
It's small
- B.
It's far to the skin surface
- C.
It's difficult to access
- D.
Lack of nearby nerve structure
Correct Answer
A. It's smallExplanation
The radial artery is not encouraged for arterial puncture because it is small in size. This can make it challenging to accurately locate and access the artery, increasing the risk of complications such as hematoma or arterial spasm. Additionally, the small size of the radial artery may limit the amount of blood that can be obtained for testing purposes.Rate this question:

Which of the following best defines hemodialysis?
- A.
It's a process of collecting blood from a person whose kidneys are faulty
- B.
It's the process through which the blood in the kidney is drained
- C.
It's the process of purifying the blood of a person whose kidneys aren't functioning normally
- D.
None of the above
Correct Answer
C. It's the process of purifying the blood of a person whose kidneys aren't functioning normallyExplanation
Hemodialysis is a medical procedure used to purify the blood of individuals with kidney dysfunction. It involves collecting the blood from the person and passing it through a dialysis machine, which filters out waste products and excess fluids. The purified blood is then returned to the person's body. This process helps to maintain the balance of electrolytes and remove toxins from the bloodstream, compensating for the impaired kidney function. The other options in the question do not accurately describe the process of hemodialysis.Rate this question:

In other to have an effective and successful peak and trough sample, which of the following is the most important?
- A.
Tubes
- B.
Timing
- C.
Puncturing site
- D.
All of the above
Correct Answer
B. TimingExplanation
Timing is the most important factor in having an effective and successful peak and trough sample. This is because the timing of the sample collection is crucial in order to accurately measure the peak and trough levels of a medication in the bloodstream. If the sample is collected too early or too late, it may not provide an accurate representation of the medication's concentration in the body. Therefore, timing plays a critical role in ensuring the reliability and usefulness of the peak and trough sample.Rate this question:

Which of the following is the study of cells in the blood?
- A.
Chemistry
- B.
Biochemistry
- C.
Hematology
- D.
B & C
Correct Answer
C. HematologyExplanation
Hematology is the study of blood and blood-forming tissues, including the cells found in the blood. It involves the examination of blood samples to diagnose and treat various blood disorders and diseases. Hematologists analyze the different types of cells in the blood, such as red blood cells, white blood cells, and platelets, to identify any abnormalities or imbalances that may indicate a health condition. They also study the functions and interactions of these cells to gain insights into the overall health and functioning of the body.Rate this question:

If tubes are chilled, which of the following will occur?
- A.
Faster gel flow
- B.
Stagnation of gel flow
- C.
Slowed gel flow
- D.
None of the above
Correct Answer
C. Slowed gel flowExplanation
When tubes are chilled, the gel inside the tubes will experience a decrease in temperature. This decrease in temperature will cause the gel to become denser and more viscous, resulting in a slower flow. Therefore, the correct answer is "Slowed gel flow."Rate this question:

An increase in red blood cells due to a decrease in plasma volume is referred to as what?
- A.
Laparotomy
- B.
Colitis
- C.
Hemoconcentration
- D.
None of the above
Correct Answer
C. HemoconcentrationExplanation
Hemoconcentration refers to an increase in the concentration of red blood cells due to a decrease in plasma volume. This can occur in conditions such as dehydration, where there is a loss of fluid from the body, leading to a relative increase in the number of red blood cells. Hemoconcentration can also be seen in certain medical conditions, such as polycythemia or shock. It is not related to laparotomy or colitis, which are surgical and inflammatory conditions, respectively.Rate this question:

When assessing a venipuncture site, which of the following is most appropriate?
- A.
The use of sense of touch
- B.
Use of sense of sight
- C.
A & B
- D.
None of the above
Correct Answer
A. The use of sense of touchExplanation
When assessing a venipuncture site, the most appropriate method is to use the sense of touch. This is because the sense of touch allows healthcare professionals to feel for the presence of veins and assess their size, depth, and condition. By using touch, they can locate the best vein for venipuncture and ensure a successful procedure with minimal discomfort for the patient. The sense of sight alone may not provide enough information about the veins, making it less appropriate for this purpose. Therefore, the combination of using the sense of touch is the most suitable approach for assessing a venipuncture site.Rate this question:
