Septicemia is defined as what?

• A. Localized infection
• B. Bruising
• C. Nerve injury
• D. Systemic infection due to introduction of pathogen during needle insertion

Answer: (D)

Septicemia is a systemic infection, meaning pathogens are present in and circulating through the bloodstream, potentially leading to widespread illness. In the context of needle insertion, it describes what can happen if pathogens are introduced into the bloodstream during the procedure, making the infection systemic rather than confined to one local area. So the best choice reflects that systemic bloodstream infection arising from introduction of a pathogen during the procedure. The other options describe problems that are not bloodstream infections: a localized infection stays in one area, bruising is bleeding under the skin, and nerve injury involves damage to nerves rather than infection spreading through the blood.
