An ESR is drawn in what color top tube?

Correct! Wrong!

Explanation:
An ESR (erythrocyte sedimentation rate) is drawn into a lavender-colored top tube. This is due to the fact that blood samples for ESR testing are frequently collected using lavender top tubes. The blood's lavender hue denotes the presence of EDTA, an anticoagulant that helps keep the blood from clotting while being tested.

The skin's avascular layer is called the?

Correct! Wrong!

Explanation:
The epidermis, which is the skin's top layer and is avascular, or devoid of blood vessels, is the outermost layer of the skin. It serves as a layer of defense from harmful outside elements including UV radiation and bacteria. On the other hand, the dermis is the layer below the epidermis and has structures like blood vessels and nerves. The hypodermis, commonly referred to as the subcutaneous layer, is the skin's lowest layer and is made up of fat and connective tissue. With the exception of the epidermis, none of the other options are accurate.

A sample would not be accepted for analysis if it met three of the following criteria. What somebody wouldn't?

Correct! Wrong!

Explanation:
If a bilirubin specimen has a yellowish coloring, which is a frequent feature of bilirubin, it is said to be icteric. Because it is typical of a bilirubin specimen, this situation would not result in the specimen being rejected for examination. On the other hand, aberrant conditions include the presence of clots in a CBC sample, lipemia in a fasting glucose sample, and hemolysis in an electrolyte sample would probably result in the specimen being rejected for analysis.

Schoolteacher Sue McGregor, 25, is being monitored for a potential eating disorder. The doctor prescribes daily weight checks. Which action needs to be avoided in order to get a precise weight?

Correct! Wrong!

Explanation:
Taking the client's weight at different times each day should be avoided to ensure an accurate assessment of weight when monitoring for possible eating disorders.

What word describes the "clotting condition"?

Correct! Wrong!

Explanation:
The condition of clotting is known as hemostasis. It is the procedure by which the body creates a clot to close off a broken blood vessel in order to halt bleeding. The physiological process that controls excessive bleeding and preserves the integrity of the circulatory system is explicitly described by this word.

Which test requires the use of whole blood?

Correct! Wrong!

Explanation:
Whole blood must be used for the Complete Blood Count (CBC) test. This examination reveals details on the various blood constituents, including platelets, white blood cells, and red blood cells. Anemia, infections, and blood problems are just a few of the conditions that it assists in diagnosing and monitoring. The analysis of whole blood is not necessary for the other tests indicated, such as BUN, CPK, and Protime.

Chinese immigrant Mr. Li, 63, is really agitated today. Which exercise do you anticipate the registered nurse recommending?

Correct! Wrong!

Explanation:
Taking a walk is a gentle form of exercise that can be very calming. It allows for fresh air, movement, and a change of scenery, all of which can have a positive impact on a person's mood. Additionally, walking can be a solitary activity, providing Mr. Li with some personal space if needed. So, in this scenario, Daily walks would likely be the recommended activity to help Mr. Li relax and alleviate his agitation. However, it's important for the nurse to assess Mr. Li's preferences and needs, as well as consider any cultural factors that might influence his choice of activity.

The brain and spinal cord make up the peripheral nervous system.

Correct! Wrong!

Explanation:
The statement presented is false. The brain and spinal cord do not make up the peripheral nervous system. Instead, it is a network of nerves and ganglia that connect the brain and spinal cord, which make up the central nervous system, to the rest of the body. Between the central nervous system and the numerous organs, muscles, and tissues in the body, the peripheral nervous system is in charge of sending messages.

What fuels the operation of STAT electrolytes?

Correct! Wrong!

Explanation:
Serum is used to power STAT electrolytes. The clear, yellowish fluid obtained when blood is allowed to coagulate is known as serum. It is perfect for conducting electrolyte tests since it lacks clotting components and blood cells. All three components of whole blood—red and white blood cells, plasma, the liquid portion of blood that contains clotting factors, and white blood cells—aren't appropriate for conducting electrolyte testing.

Which one of the following lab staff is referred to as a clinical laboratory scientist?

Correct! Wrong!

Explanation:
The correct answer is medical technologist. A medical technologist is another name for a clinical laboratory scientist, a scientist who works in a laboratory setting in the healthcare or pharmaceutical industry. A medical technologist performs complex tests on biological samples and reports results to physicians.

Heparin works to stop blood coagulation by?

Correct! Wrong!

Explanation:
Heparin inhibits thrombin, which stops blood from clotting. Thrombin is an enzyme that transforms fibrinogen into fibrin, which creates the meshwork of a blood clot, and so plays a significant role in the clotting process. Heparin efficiently prevents the development of blood clots by blocking thrombin.
