D. Both B and C

Answer: D

When preparing to insert a catheter for intravenous fluids during surgery, factors that influence the site location choice include the infusion duration and the condition of the vein for use. An infusion that will run over a long period requires a vein that will tolerate the instillation of large amounts of fluid over time, rather than a short injection of fluid or medication. Additionally, veins that are in poor condition may be difficult to cannulate and may not tolerate a fluid infusion.

In this situation, the nurse is responsible for the aide’s actions, because they

      Answer: D

      
      

      Employers are required to provide measures for hand hygiene practices. If employees are expected to wash their hands to protect themselves from blood borne pathogens, employers are mandated to provide materials for them, according to the Occupational Safety and Health Administration. Food and drink should be separate from operative procedures and not in the same room, and contaminated needles should never be recapped to reduce risk of injury. All healthcare personnel should receive training on exposure to blood borne pathogens.
