1. which of the following is the most important point of teaching for visitors to prevent the patient from being exposed to other infectious agents?

wearing gloves whenever coming in contact with the patient
wearing a gown and mask whenever entering the patients room

cleansing of room surfaces with germicidal wipes daily

1. what is the goal of the use of a high - efficiency particulate air (hepa) filter in the patients room?

air decontamination
air sterilization
air degermination
air disinfection

Explanation:

1. Cleansing line cap with alcohol swab: Alcohol swab helps in reducing microbial load on the cap. Changing dressing with sterile procedure: Sterile procedure minimizes contamination. Wearing gloves: Reduces transfer of microbes. So all are part of aseptic technique.
2. Chlorhexidine is the gold - standard for skin antisepsis in central venous line dressing changes as it has broad - spectrum activity and persistent effects.
3. Hand hygiene (washing or using antiseptic hand sanitizer) is the most important as it is the main route of transmission of infectious agents from visitors.
4. HEPA filters remove particles (including some microbes) from the air, which is a form of air decontamination. Sterilization implies complete removal of all microbes (not practical for air in a room), degermination is a less - used term, and disinfection usually refers to chemical methods.

Answer:

1. All of these choices are correct.
2. Chlorhexidine
3. Hand hygiene by washing or antiseptic hand sanitizer application when entering and leaving room
4. Air decontamination
