Which of the following is the purpose of warming infants prior to a heel puncture?

To soften
To increase flow of blood
To decrease flow of blood
All of the above

Correct Answer

A. To increase flow of blood

Explanation

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.

An increase in red blood cells due to a decrease in plasma volume is referred to as what?

Laparotomy
Colitis
Hemoconcentration
None of the above

Correct Answer

A. Hemoconcentration

Explanation

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.

Which of the following best defines hemodialysis?

It's a process of collecting blood from a person whose kidneys are faulty
It's the process through which the blood in the kidney is drained
It's the process of purifying the blood of a person whose kidneys aren't functioning normally
None of the above

Correct Answer

A. It's the process of purifying the blood of a person whose kidneys aren't functioning normally

Explanation

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.

Which of the following is the study of cells in the blood?

Chemistry
Biochemistry
Hematology
B & C

Correct Answer

A. Hematology

Explanation

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.

Which of the following statement is true?

A tourniquet is very essential to effectively perform a finger stick
A syringe isn't needed for a finger stick
A lancet is very crucial in performing a finger stick
B & C

Correct Answer

A. B & C

Explanation

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.

When assessing a venipuncture site, which of the following is most appropriate?

The use of sense of touch
Use of sense of sight
A & B
None of the above

Correct Answer

A. The use of sense of touch

Explanation

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.

If tubes are chilled, which of the following will occur?

Faster gel flow
Stagnation of gel flow
Slowed gel flow
None of the above

Correct Answer

A. Slowed gel flow

Explanation

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."

In other to have an effective and successful peak and trough sample, which of the following is the most important?

Tubes
Timing
Puncturing site
All of the above

Correct Answer

A. Timing

Explanation

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.

Why is it not encouraged to make use of the radial artery for arterial puncture?

It's small
It's far to the skin surface
It's difficult to access
Lack of nearby nerve structure

Correct Answer

A. It's difficult to access

Explanation

The radial artery is relatively small and located deep within the wrist, making it challenging to access compared to other arteries like the brachial or femoral arteries. This difficulty in access can increase the risk of complications during arterial puncture procedures.
