The farthest point from the point of attachment of a body part or structure.

The plane that divides the body into front (anterior) and back (posterior) sections.

An organ that aids in digestion but is not part of the digestive tract itself.

The point on a body part or structure that is closest to its point of attachment.

The outermost layer of skin, lacking blood vessels.

One of the four basic tissue types, responsible for covering and lining surfaces in the body.

Protective membranes that surround the spinal cord and brain.

The smallest blood vessels, where gas exchange between blood and tissues occurs.

A major difference between arteries and veins is that veins have valves, which prevent blood from flowing backward.

The chamber of the heart that receives blood from the systemic circulation, which is the blood that has circulated throughout the body.

Also known as the myocardium, is the thick muscular layer of the heart responsible for pumping blood.

The systolic pressure is the first heart sound you hear as the blood pressure cuff is deflated.

The internal space of a blood vessel through which blood flows.

The liquid portion of a clotted blood specimen, which is the plasma without the clotting factors.

A tube with a light blue stopper is used to collect blood for coagulation tests.

A tube with a green stopper typically contains heparin, an anticoagulant that prevents blood from clotting.

The process of obtaining a blood sample by pricking the skin, usually the fingertip or heel.

The preferred site for skin puncture on infants, located on the outer side of the heel.

A specialized lancet designed to collect blood from the heel of infants.

The bottom surface of the heel.

A hereditary disorder that prevents the body from breaking down phenylalanine, an amino acid.

A condition in newborns characterized by yellowish skin and eyes caused by high levels of bilirubin.

A needle-like instrument used to make a small puncture in the skin for blood collection.

A special container used for collecting small blood samples, often used for skin puncture.

A tourniquet is a device that constricts blood flow in a vein, making it easier to locate and draw blood.

The vacuum inside the tubes pulls the blood in automatically.

Butterfly needles are specifically designed for drawing blood from difficult or hand veins due to their smaller size and flexibility.

Needles are categorized by their gauge, which indicates the diameter of the needle's opening.

According to OSHA regulations, the tube holder with the attached needle must be disposed of as a single unit after use to prevent sharps injuries and contamination.

The barrel of a syringe is the part that shows measurements in cc or mL, allowing for precise volume control during blood collection.

Gauze pads are preferred over cotton balls because cotton fibers can stick to the venipuncture site, causing discomfort and potentially affecting the specimen quality.

A venoscope is a device that uses transillumination to make veins more visible under the skin, aiding in vein location during venipuncture.

The most suitable angle for needle insertion during venipuncture. It helps to ensure that the needle properly enters the vein and minimizes the risk of tissue damage.

During venipuncture, the bevel of the needle should be facing upwards. This allows the needle to enter the vein smoothly and minimizes the chances of damaging the vein wall.

The ideal time to release the tourniquet during venipuncture is as soon as blood starts flowing into the tube. This ensures proper blood flow while minimizing venous stasis.

When a hematoma is present, the blood collection should be done distally (away from) the hematoma. This avoids drawing blood from the affected area and minimizes the risk of further complications.

Prolonged tourniquet application can lead to hemoconcentration, a condition where the blood becomes thicker and concentrated. This can affect the accuracy of lab test results.

Reflux refers to the backward flow of blood from the collection tube into the vein. This can contaminate the sample and affect test results. The best way to prevent reflux is to ensure the tubes fill from the bottom up and avoid any pressure on the tube.

A basal state refers to a resting metabolic state where the body is at its most stable and predictable condition. This state is typically achieved after a night of fasting and rest.

Collecting blood from a screaming infant can lead to a falsely elevated white blood cell count. This is because stress and crying release hormones that can increase the number of white blood cells in the blood.

The site should be prepped with a suitable disinfectant like povidone-iodine to minimize the risk of infection.

The modified Allen test is used to assess the adequacy of collateral circulation in the hand, ensuring that the radial artery is safe to puncture.

A thrombus, or blood clot, in the radial artery can be suspected if the pulse distal to the puncture site (away from the heart) is weak or absent. This means the clot is obstructing blood flow.

Heparin is essential in arterial blood gas samples to prevent clotting. Clotting would alter the gas content of the blood making the results inaccurate.

The radial artery is located on the thumb side of the wrist, making it a common site for arterial blood gas collection.
