The terms "contraction" and "relaxation" can be used to describe the phases of the cardiac cycle and can be equated with the terms "systolic" and "diastolic" respectively.
An increase in red blood cells due to a decrease in plasma volume is referred to as hemoconcentration. Hemoconcentration occurs when there is a decrease in the liquid component of blood (plasma) relative to the cellular components, particularly red blood cells (RBCs).
Capillary tubes are indeed used for collecting blood in certain situations. Capillary tubes are thin, cylindrical tubes made of glass or plastic that are specifically designed for the collection of capillary blood samples. Capillary blood samples are obtained through procedures such as finger sticks or heel sticks.
The process of purifying the blood of a person whose kidneys aren't functioning normally is best defined as hemodialysis. Hemodialysis is a medical procedure used to treat individuals with end-stage renal disease (ESRD) or acute kidney injury (AKI) by removing waste products, excess fluids, and toxins from the bloodstream.
The purpose of warming infants prior to a heel puncture (also known as a heel stick or capillary blood sampling) is to increase blood flow to the puncture site. Warming the infant's heel helps dilate the blood vessels in the area, making it easier to obtain an adequate blood sample for testing.
Proper handwashing is essential for infection control in healthcare settings, including phlebotomy procedures. It helps reduce the risk of spreading pathogens between patients and healthcare workers.
Antiseptics are chemical substances used to clean and disinfect human skin by inhibiting the growth of microorganisms. They are applied to the skin or mucous membranes to reduce the number of bacteria, fungi, viruses, and other microorganisms present. Antiseptics are commonly used in healthcare settings, including hospitals, clinics, and during various medical procedures.
The terms "source," "mode of transmission," and "susceptible host" are indeed key components of the chain of infection. The chain of infection is a concept used in epidemiology to describe the process by which infectious diseases spread. It consists of several interconnected steps or links that must be present for an infection to occur and continue its transmission.
Contamination refers to the process by which an area or object becomes unclean or dirty. It involves the introduction of harmful or undesired substances, microorganisms, or pollutants into an environment or onto a surface, compromising its cleanliness or safety.
Timing is crucial for an effective and successful peak and trough sample collection. Peak and trough levels are measurements of the highest and lowest concentrations of a drug in the bloodstream, respectively. These samples are typically collected to monitor the therapeutic drug levels and ensure optimal dosing and patient safety.
Blood is indeed the most common source of transmission for Hepatitis B (HBV), Hepatitis C (HCV), and Human Immunodeficiency Virus (HIV). These bloodborne pathogens can be transmitted through contact with infected blood or blood products.
It is true that human skin is always covered with bacteria. The human skin is home to a diverse microbial community known as the skin microbiota or skin microbiome. This microbial community consists of various types of bacteria, fungi, viruses, and other microorganisms.
Hematology is the branch of medicine and biology that focuses on the study of cells in the blood and their related disorders. It encompasses the examination, diagnosis, treatment, and prevention of various conditions affecting blood cells, including red blood cells, white blood cells, and platelets.
If tubes are chilled, it can result in slowed gel flow in certain types of tubes used for laboratory testing. Gel tubes are commonly used in blood collection to separate serum or plasma from the cellular components of the blood.
When assessing a venipuncture site, the use of the sense of touch (palpation) is indeed most appropriate and commonly employed by healthcare professionals. Palpation allows the healthcare provider to assess the condition of the veins and determine their suitability for venipuncture.

A lancet is a crucial tool for performing a finger stick, also known as a finger prick or capillary blood sampling. In this procedure, a lancet is used to create a small puncture or incision on the fingertip, allowing for the collection of a small blood sample for testing or monitoring purposes.
