RATIONALE : Clippers cause the least trauma, always immediately before surgery. Hair removal in general may not reduce rate of SSIs and may increase risk of infection IPC plan for an ambulatory surgery center should be evaluated (multiple options possible): I - annually
Bedra ils Floor s Ventilation grilles Window curtains ANS:->>> Bedrails, because they are high touch. Others only require frequent cleaning if visibly soiled Which preventive measures are recommended to prevent community-acquired pneumonia?: Pneumococcal vaccination Herpes zoster vaccination Influenza vaccination Smoking cessation ANS:->>> Pneumococcal vaccine, influenza vaccine, smoking cessation The best time to collect a sputum specimen for acid-fast bacilli is: Early morning Midday
Afternoon Bedtime ANS:->>> Early morning A distribution curve that has a skew value of +3 will exhibit what shape? **ANS:-
An enlarged tail to the right**. RATIONALE : This is indicating there are more data than expected on the right (or positive) end of the distribution curve. Skew is positive when the mean is greater than the median, negative when the mean is lesser than the median. Value of 0 = normal bell curve with no skew. Negative value = skew to the left.

ANS:->>> 6 - 7 days before symptoms occur With which teaching style (Grasha) does the IP focus on content rather than relationships w/ learners?: Demonstrat or Formal authority Facilitator Expert ANS:->>> Formal authority In outbreak investigation, a line list & epi curve have been completed. Before generating hypotheses, the next step should be to: Establish plan for methodology Conduct lit review Conduct brainstorming session Determine what resources are needed ANS:->>> Conduct lit review to ID other
Toxigenic culture Toxic enzyme immunoassay (EIA) ANS:->>> NAAT, including PCR, has excellent sensitivity/specificity, is quick, but is expensive When considering reprocessing medical devices, most facilities will require: A contract w/ third party reprocessing organization Increasing training for staff regarding reprocessing procedure Hiring of additional personnel Improved sterilization, processing equipment ANS:->>> A contract w/ third party reprocessing organization Burn patients are especially at risk due to: Overall immunosuppresion Loss of skin barrier Use of invasive devices Microorganisms's development of resistance to topical abx ANS:->>> All of the above Which agency regulates medical waste and incinerators? ANS:->>> EPA Most common cause of early-onset neonatal meningitis is maternal trANSWERmission of: Neisseria gonorrhoeae Group B
streptococcus Cytomegalovirus Toxoplasma gondii ANS:->>> Group B strep Epi curve that rises slowly and then plateaus most likely represents:
I - Placing exist site of catheter at beltline II - Using double-cuff catheter III - Using strict aseptic technique IV - Avoiding baths/showers until insertion site heals ANS:->>> II - Using double-cuff catheter
III - Using strict aseptic technique IV - Avoiding baths/showers until insertion site heals What clinical manifestation in a pediatric patient should give an IP a high index of suspicion for chicken pox?: A.
