Free NAPTP Phlebotomy Preparations Question and Answers — Questions and Answers
Question 1: EDTA
- Calcium Citrate binding agent used as an anticoagulant
- Citric binding agent used as a coagulant
- Calcium binding agent used as an anticoagulant (Correct answer)
- Calcium binding agent that is used for laboratory coagulation
Correct answer: Calcium binding agent used as an anticoagulant
EDTA (ethylenediaminetetraacetic acid) is a calcium binding agent that is commonly used as an anticoagulant. It works by chelating or binding to calcium ions, which are necessary for the coagulation process. By removing calcium ions, EDTA prevents the blood from clotting, making it an effective anticoagulant. This property makes it useful in various medical and laboratory settings, such as blood collection tubes or in certain medical procedures where anticoagulation is required.
Question 2: PTT is the abbreviation for:
- Partial Therapeutic Time
- Partial Thromboplastin Time (Correct answer)
- Partial Thrombin Test
- Partial Participation Time
Correct answer: Partial Thromboplastin Time
PTT stands for Partial Thromboplastin Time, which is a laboratory test used to measure the time it takes for blood to clot. It is commonly used to monitor the effectiveness of blood-thinning medication, such as heparin. The test measures the time it takes for a clot to form after certain substances are added to a blood sample. By measuring PTT, healthcare professionals can assess a patient's risk of excessive bleeding or blood clotting disorders.
Question 3: Lavender Tubes contain
- SST
- Sodium Citrate
- EDTA (Correct answer)
- Sodium Heparin
Correct answer: EDTA
Lavender Tubes contain EDTA, which stands for ethylenediaminetetraacetic acid. EDTA is an anticoagulant that prevents blood from clotting by binding to calcium ions, which are necessary for the coagulation process. This type of tube is commonly used for hematology tests, such as complete blood count (CBC), as it preserves the blood cells and prevents clotting during transportation and analysis.
Question 4: Vacutainer System
- Combination of Vacutainer holder, syringe, needle and sample tubes which allows for a more measured method of blood drawing
- Combination of Vacutainer tubes, needle and sample holder which allows for a more automated method of drawing blood
- Combination of Vacutainer syringe, needle, holder and sample tubes which allows for a more automated method of drawing blood
- Combination of Vacutainer holder, needle and sample tubes which allows for a more automated method of drawing blood (Correct answer)
Correct answer: Combination of Vacutainer holder, needle and sample tubes which allows for a more automated method of drawing blood
The Vacutainer System consists of a Vacutainer holder (also known as a Vacutainer adapter), a needle, and sample tubes. This system allows for a more automated method of drawing blood by using vacuum pressure to fill sample tubes with blood during venipuncture.
Question 5: Whole Blood:
- Blood from which all elements have been removed and replaced
- Blood from which none of the essential platelet elements have been removed
- Blood from which none of the elements have been removed (Correct answer)
- Blood that is whole, complete and not void of white blood cells
Correct answer: Blood from which none of the elements have been removed
The correct answer is "Blood from which none of the elements have been removed." This means that whole blood refers to blood that has not had any of its components, such as red blood cells, white blood cells, platelets, or plasma, removed. It is a complete sample of blood that contains all of its natural components.
Question 6: Hyperglycemia
- Abnormally low sodium levels
- Abnormally low blood sugar levels
- Abnormally high blood sugar levels (Correct answer)
- Abnormally formed blood sugar levels
Correct answer: Abnormally high blood sugar levels
Abnormally high blood sugar levels, also known as hyperglycemia, occur when there is an excessive amount of glucose in the bloodstream. This can happen due to various reasons such as insufficient insulin production, insulin resistance, or certain medical conditions. Hyperglycemia can lead to symptoms such as increased thirst, frequent urination, fatigue, and blurred vision. If left untreated, it can cause serious complications such as diabetic ketoacidosis. Therefore, abnormally high blood sugar levels are a correct explanation for hyperglycemia.
Question 7: What are the two tiers or levels of precautions?
- Standard precautions and transmission-based precautions (Correct answer)
- Simple precautions and transmission fluid pathogens
- Substitute precautions and mode of transmission-based precautions
- None of the above
Correct answer: Standard precautions and transmission-based precautions
The two tiers or levels of precautions are standard precautions and transmission-based precautions. Standard precautions are a set of infection control practices that are applied to all patients, regardless of their diagnosis or presumed infection status. These precautions include hand hygiene, the use of personal protective equipment, safe injection practices, and respiratory hygiene. Transmission-based precautions, on the other hand, are additional precautions that are used for patients with known or suspected infections that are spread through specific routes, such as airborne, droplet, or contact transmission. These precautions include the use of specialized personal protective equipment and specific isolation measures to prevent the spread of the infection.
Question 8: What is the main difference between arterial and venous blood?
- Arterial blood is deoxygenated, venous blood is oxygenated.
- Arterial blood is red Venous blood is blue
- Arterial blood is oxygenated, venous blood is deoxygenated (Correct answer)
- None of the above
Correct answer: Arterial blood is oxygenated, venous blood is deoxygenated
The main difference between arterial and venous blood is the oxygenation level. Arterial blood is oxygenated, meaning it carries oxygen from the lungs to the body's tissues. On the other hand, venous blood is deoxygenated, as it has already delivered oxygen to the tissues and is returning to the heart and lungs to be reoxygenated. The statement "arterial blood is oxygenated, venous blood is deoxygenated" accurately describes this distinction.
Question 9: Pink tube is used for
- Cellular Blood Banking
- Blood Tubes Banking
- Blood Banking (Correct answer)
- Banking
Correct answer: Blood Banking
The pink tube is used for blood banking. Blood banking involves the collection, testing, processing, and storage of blood and blood components for transfusion. The pink tube is specifically used for collecting samples for blood banking purposes, such as cross-matching and antibody screening. This tube contains an anticoagulant called EDTA, which helps prevent the blood from clotting and allows for accurate testing and storage.
Question 10: Basilic Vein
- Large vein on outer side of bicep
- Large vein in the middle of the arm
- Small vein on the inner side of bicep
- Large vein on the inner side of the bicep (Correct answer)
Correct answer: Large vein on the inner side of the bicep
The Basilic Vein is a large vein located on the inner side of the bicep. It is commonly used for venipuncture procedures and for intravenous access.
Question 11: Tourniquet
- Constrictive band used for venipuncture, blood aspiration and intravenous injections (Correct answer)
- Plastic band that easily breaks, mainly used for patients with blood disease
- Nylon band used to make intravenous injections
- Constrictive rubber tied in a knot used for patient's needing medical attention
Correct answer: Constrictive band used for venipuncture, blood aspiration and intravenous injections
The correct answer is "Constrictive band used for venipuncture, blood aspiration and intravenous injections." This answer accurately describes the purpose and use of a tourniquet. It is a constrictive band that is applied to a limb to temporarily stop or slow down the flow of blood, making it easier to locate and access veins for procedures such as venipuncture, blood aspiration, and intravenous injections.
