A medical assistant should report which of the following as outside the expected reference range when obtaining vitals?

A. Yellow: The yellow tube, used for blood cultures, is typically collected first to prevent contamination.
B. Light blue: The light blue tube is used for coagulation studies and should be collected before tubes containing additives that could interfere with coagulation tests.
C. Red: The red tube, which may contain no additives or a clot activator, is usually collected after the light blue tube.
D. Gray: The gray tube is used for glucose testing and should be filled last as it contains additives that could interfere with other tests if collected earlier.

A. Reservoir: The reservoir is the place where a pathogen lives and multiplies, such as a human, animal, or environment. It is not how the pathogen enters a new host.
B. Susceptible host: The susceptible host is the individual who can potentially be infected by the pathogen. However, this term does not describe how the pathogen enters the host.
C. Portal of entry: The portal of entry is the correct term for the route by which a pathogen enters a new host, such as through the respiratory tract, gastrointestinal tract, or broken skin.
D. Mode of transmission: The mode of transmission refers to how the pathogen is spread from one host to another, such as through direct contact, airborne particles, or vectors. It does not describe how the pathogen enters the host.
