NCCT Phlebotomy Questions and Answers

1.

The forearm vein most commonly used for venipuncture is the ________.
- A.
  
  Median cubital
- B.
  
  Basilic
- C.
  
  Cephalic
- D.
  
  Radial
Correct Answer
A. Median cubital

Explanation
The median cubital vein is the most commonly used vein for venipuncture because it is large, easily accessible, and usually lies close to the surface of the skin. It is located in the antecubital fossa, the shallow depression on the anterior aspect of the elbow. This vein is preferred for blood draws and intravenous access because it tends to have fewer surrounding nerves and arteries, reducing the risk of complications.

The smallest veins in the human body are known as ________.
- A.
  
  Villi
- B.
  
  Bronchioles
- C.
  
  Venules
- D.
  
  Lymph glands
Correct Answer
C. Venules

Explanation
Venules are the smallest veins in the human body. They collect blood from the capillaries, where the exchange of oxygen, carbon dioxide, and other substances with tissues occurs, and transport it to larger veins, eventually returning it to the heart. Venules play a crucial role in the circulatory system by helping to regulate blood flow and pressure between the capillaries and the larger veins. They are an essential component of the body's vascular network, ensuring efficient circulation of blood.

The aorta branches into smaller divisions called arteries, which in turn branch into even smaller divisions called __________.
- A.
  
  Capillaries
- B.
  
  Arterioles
- C.
  
  Venules
- D.
  
  Lymph glands
Correct Answer
B. Arterioles

Explanation
Arterioles are the smaller divisions of arteries that branch off to deliver blood to the capillaries. They play a key role in regulating blood flow and pressure within the circulatory system. Arterioles control blood distribution by constricting or dilating, thereby regulating the amount of blood that reaches various tissues and organs. This regulation is crucial for maintaining proper blood pressure and ensuring that oxygen and nutrients are efficiently delivered to the cells.

Characteristics of capillaries include _________.
- A.
  
  All of the above
- B.
  
  Having thin-walls
- C.
  
  Forming microscopic pathways
- D.
  
  Connecting arterioles with venules
Correct Answer
A. All of the above

Explanation
Capillaries have several key characteristics: they have thin walls, form microscopic pathways, and connect arterioles with venules. The thin walls of capillaries, which consist of a single layer of endothelial cells, allow for the exchange of oxygen, carbon dioxide, nutrients, and waste products between the blood and surrounding tissues. Capillaries are the smallest blood vessels and form a vast network of microscopic pathways throughout the body, facilitating efficient transport and exchange at the cellular level. They connect the smallest arteries (arterioles) to the smallest veins (venules), completing the circulatory loop.

5.

Within the capillaries, blood cell functions include ________.
- A.
  
  Releasing oxygen
- B.
  
  Binding carbon dioxide
- C.
  
  Eliminating waste
- D.
  
  All of the above
Correct Answer
D. All of the above

The heart, lymphatic organs, and blood vessels are in the ________ system.
- A.
  
  Respiratory
- B.
  
  Cardiovascular
- C.
  
  Digestive
- D.
  
  Urinary
Correct Answer
B. Cardiovascular

Explanation
The cardiovascular system includes the heart, blood vessels, and lymphatic organs. The heart pumps blood through the blood vessels, which transport oxygen, nutrients, and waste products throughout the body. The lymphatic system, which is part of the cardiovascular system, helps maintain fluid balance and protects against infections by transporting lymph, a fluid containing white blood cells. Together, these components work to ensure that the body's tissues receive the necessary substances for proper function and that waste products are removed efficiently.

The suffix -URIA at the end of a medical term refers to what body location?
- A.
  
  Bloodstream
- B.
  
  Urine
- C.
  
  Kidney
- D.
  
  Synovial fluid
Correct Answer
B. Urine

Explanation
The suffix -URIA in medical terminology refers to urine. It is used to describe conditions related to the presence of certain substances or the nature of the urine. For example, "hematuria" means the presence of blood in the urine, and "proteinuria" indicates the presence of protein in the urine. This suffix helps specify the type of condition or abnormality that is being discussed in relation to urine and its components.

The study of blood is known as ___________.
- A.
  
  Hematology
- B.
  
  Hematoxylin
- C.
  
  Hemoglobin
- D.
  
  Hemolysis
Correct Answer
A. Hematology

Explanation
Hematology is the branch of medicine that studies blood, blood-forming organs, and blood diseases. It involves the diagnosis, treatment, and prevention of blood-related disorders such as anemia, leukemia, lymphomas, and clotting abnormalities. Hematologists are specialists who analyze blood samples, identify blood disorders, and develop treatment plans to manage or cure these conditions. The field of hematology is essential for understanding how blood functions in health and disease, and for developing therapies to treat blood-related illnesses.

The liver, stomach, mouth, and pancreas are in the ___________ system.
- A.
  
  Reproductive
- B.
  
  Sensory
- C.
  
  Digestive
- D.
  
  Muscular
Correct Answer
C. Digestive

Explanation
The liver, stomach, mouth, and pancreas are all part of the digestive system. This system is responsible for breaking down food into nutrients that the body can absorb and use for energy, growth, and repair. The mouth initiates digestion by chewing and mixing food with saliva. The stomach further breaks down food with acids and enzymes. The liver produces bile to aid in fat digestion, and the pancreas produces enzymes that assist in digesting proteins, fats, and carbohydrates. Together, these organs work to ensure efficient digestion and nutrient absorption.

The most important step to ensure accuracy in sample collection is ____________.
- A.
  
  Recording the time accurately
- B.
  
  By always wearing gloves
- C.
  
  Keeping the patient supine
- D.
  
  Identifying the patient properly
Correct Answer
D. Identifying the patient properly

Explanation
Properly identifying the patient is the most crucial step to ensure accuracy in sample collection. Accurate identification prevents errors such as collecting samples from the wrong patient, which can lead to incorrect diagnoses and treatment. This process typically involves verifying the patient's name, date of birth, and other identifying information before proceeding with sample collection. Ensuring correct patient identification enhances the reliability of test results and patient safety, making it a fundamental practice in medical and clinical settings.
