If you are trying to stop the bleeding from a needle stick, which of the following is the best technique?

Indirect pressure
Direct pressure
Tourniquet
Longitudinal pressure

Correct Answer

A. Direct pressure

Explanation

Direct pressure is the best technique to stop the bleeding from a needle stick. Applying direct pressure to the site of the bleeding helps to compress the blood vessels and reduce blood flow, allowing the blood to clot and the bleeding to stop. This can be done by using a clean cloth or dressing and applying firm pressure directly on the wound. Indirect pressure, tourniquet, and longitudinal pressure are not recommended in this situation as they may not effectively control the bleeding or may cause further damage.

Which of the following matches the definition: excessive RBC production?

Polycythemia
Dehiscence
Transection
Escharotic's condition

Correct Answer

A. Polycythemia

Explanation

Polycythemia is the condition characterized by excessive production of red blood cells (RBCs). This results in an increased number of RBCs in the blood, leading to thickening of the blood and potential complications such as blood clots. Dehiscence refers to the separation of wound edges, transection refers to the cutting across of a structure, and "Escharotic's condition" is not a recognized medical term. Therefore, the correct answer that matches the definition of excessive RBC production is Polycythemia.

PKU Tests are most commonly performed with ___.

Skin puncture blood
Arterial blood
Bilirubin specimens
BUN anaylsis

Correct Answer

A. Skin puncture blood

Explanation

PKU (Phenylketonuria) tests are most commonly performed using skin puncture blood. Skin puncture blood refers to the blood sample obtained by pricking the skin, usually on the heel or finger, to collect a small amount of blood. This method is commonly used in newborn screening programs to detect PKU, a genetic disorder that affects the body's ability to break down an amino acid called phenylalanine. Skin puncture blood is preferred for PKU testing as it is less invasive and easier to collect, especially in infants. Arterial blood, bilirubin specimens, and BUN analysis are not typically used for PKU testing.

The area of a blood smear that is tested is called the _____.

Analyte
Whorls
Feather
Agate

Correct Answer

A. Feather

Explanation

The correct answer is "Feather" because in a blood smear, the area that is tested is spread out in a feather-like pattern on a slide. This allows for a thin and even distribution of the blood sample, making it easier to examine under a microscope. The feathered edge of the blood smear is where the cells are most evenly spread, providing a clear view of the different types of blood cells present.

Which of the following is the deepest layer of the epidermis?

Stratum spinosum
Stratum corneum
Stratum granulosum
Stratum basale

Correct Answer

A. Stratum basale

Explanation

The correct answer is the stratum basale. This is the deepest layer of the epidermis and is responsible for the production of new skin cells. It contains cells called basal cells, which continuously divide and push older cells towards the surface of the skin. The stratum basale also contains melanocytes, which produce the pigment melanin that gives color to the skin.

Which of the following is a test used to monitor heparin levels?

SST
ACT
POCT
H&H

Correct Answer

A. ACT

Explanation

ACT stands for Activated Clotting Time and is a test used to monitor heparin levels. Heparin is an anticoagulant medication used to prevent blood clots. The ACT test measures the time it takes for blood to clot after adding an activator, which reflects the effectiveness of heparin in preventing clotting. By monitoring heparin levels through ACT testing, healthcare providers can ensure that patients are receiving the appropriate dosage of heparin to prevent clotting while minimizing the risk of bleeding complications.

Which of the following is identified by the acronym (CPD)?

Cervical Positioning Device
Citrate Phosphate Dextrose
Citrate Potassium Dextrose
Citrate Potassium Disinfectant

Correct Answer

A. Citrate Phosphate Dextrose

Explanation

CPD stands for Citrate Phosphate Dextrose. Citrate Phosphate Dextrose is a solution used in blood transfusions to prevent the blood from clotting. It is a combination of citrate, phosphate, and dextrose, which work together to preserve the viability of the red blood cells during storage. This solution is commonly used in blood banks and hospitals for the storage and transfusion of blood and blood products.
