Exam 4: Infection Prevention and Control

The accumulation of dust,debris,and other microbial contaminants is a potential source of SSIs.Guidance for cleaning processes in the perioperative area states that perioperative staff should:

The mechanism of lethality (microbial death)with steam sterilization is achieved with this event:

The American College of Surgeons and Surgical Infection Society released guideline for the prevention and treatment of surgical site infections (SSI)in 2016.Key measures include:

Effective instrument decontamination is dependent on a particular sequence designed to lower bioburden to the lowest level.What is the first step in processing a basic set of laparotomy instruments through decontamination?

The surgical hand scrub is designed to:

The skin preparation for a vaginal-assisted laparoscopic hysterectomy begins ______________ and _____________.

Sterile surgical drapes are used to create the sterile field,protecting the patient from endogenous and exogenous sources of contamination.Which action is essential to maintaining the sterile field?

To protect the forearms,hands,and clothing from contacting bacteria on the outside of the used gown and gloves,members of the scrubbed surgical team should use the following procedure to remove soiled gowns and gloves.Which choice lists the appropriate first three steps in the removal of the sterile gown?

The Centers for Disease Control and Prevention (CDC)have identified pathogens that could pose a threat to national and world security and safety through bioterrorism.Select the four most probable agents that could be used to cause mass transmission,mortality,panic,and social disruption.

Sterilization prepares instruments to be used within,and on,sterile tissues.It kills vegetative microorganisms and endospores within a probability of 10⁶.The process of decontamination prepares instruments to be:

An integrator is a multiparameter indicator designed to measure:

With the production of more steam in the sterilizer chamber,the pressure increases as well.The steam should contain little or no entrapped liquid water.Steam quality is the term that describes the amount of water mixed with the steam.The constitution of high-quality steam would be measured by:

When applying sterile drapes to create the sterile field on the patient,which of the following principles is most important?

Closed gloving is the technique of choice for the initial donning of sterile gloves by the scrubbed team member; however:

A swab of a fluid collection from an edematous,red,and suppurative postoperative wound is sent to the microbiology lab for culture,sensitivity,and Gram stain.The surgeon expects that the result will show a gram-positive coccus.This Gram stain designation is based on the:

Both sterilization and disinfection describe the elimination of microbial contamination and the achievement of a state suitable for patient care in select situations.However,disinfection differs from sterilization in that the process for disinfection uses:

If a sterile glove becomes contaminated during the procedure,the best practice for corrective action is:

Within a steam sterilizer,at a temperature of 100° C (212° F),the water condensation and the steam are the same temperature.This scientific phenomenon is called ___________________ and will __________________.

Qualities of an effective packaging material must include several key characteristics.Select the three most important qualities.

The scrub person is preparing to self-don a wraparound sterile gown before surgery.Select the best practice to follow for the self-gowning procedure:
