Which of the following eating disorders is characterized by the use of laxatives and vomiting after binge eating?

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.

A. Wipe away the first five drops of blood after puncturing: Only the first drop of blood should be wiped away to remove any tissue fluid, not the first five drops.
B. Apply even pressure to the finger during the collection: Applying even pressure helps to promote blood flow without causing hemolysis or excessive squeezing, which could affect test results.
C. Puncture the index finger at the tip: The recommended site for a capillary puncture is the side of the middle or ring finger, not the tip of the index finger.
D. Puncture parallel to the fingerprint: The puncture should be made perpendicular to the fingerprint ridges to ensure an adequate blood flow and reduce the risk of blood running along the ridges.
