CIC Studying 2024: CIC Practice Exam Questions With Verified Answers Recipients of allogenic hematopoeietic stem transplantation (HSCT) should be placed
... [Show More] in rooms with how many air exchanges per hour? 3 5 10 12 A greater number of air exchanges per hour prevent opportunistic infections among stem cell transplant recipients Because of the increased risk of infection with parenteral nutrition, the maximum infusion time for a parenteral lipid bag to run is? 6 hours 12 hours 18 hours 24 hours Lipid emulsions pose greatest risk of contamination w/ bacteria or fungi The single most effective method of controlling hospital-acquired infections (HAI) is: Screening patients Isolating infected patients Handwashing Immunizing staff members If a breastfeeding mother develops mastitis, the most likely cause is: Infant colonized with Staphylococcus aureus Inadequate cleansing of breast Maternal flora invading nipple Contaminated breast pump 50% of neonates become colonized w/ S. aureus w/in a few days of birth, & pass infection into breast If hair removal is required for a surgical procedure, the BEST method is to: Shave hair with razor immediately before the incision Remove hair with a depilatory the night before surgery Remove hair with clippers the night before surgery Remove hair with clippers immediately before incision 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 II - monthly III - when risks change IV - when staff members change How long after exposure to Hep A are IgM antibodies to HAV detectable in the blood? 48 hrs 7 days 3 weeks 1-10 weeks For patients who require hemodialysis, which type of vascular access device (VAD) poses the lowest risk of infection? Arteriovenous graft Subclavian catheter Arteriovenous fistula Right internal jugular catheter Placed in the arm rather the thigh. Patients w/ catheters have 7x the risk of infection (subclavian catheters have high risk). Patients w/ chronic kidney disease should have vascular access preserved and AV fistulas created as soon as possible Which items in medical facility require most frequent environmental cleaning? Bedrails Floors Ventilation grilles Window curtains 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 The best time to collect a sputum specimen for acid-fast bacilli is: Early morning Midday Afternoon Bedtime A distribution curve that has a skew value of +3 will exhibit what shape? An enlarged tail to the right. 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. How long does a patient remain infectious after exposure to West Nile virus? 6-7 days before symptoms occur With which teaching style (Grasha) does the IP focus on content rather than relationships w/ learners? Demonstrator Formal authority Facilitator Expert 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 Conduct lit review to ID other outbreaks w/ similar profiles Which diagnostic tests for C. difficile has the BEST sensitivity and specificity? Nucleic acid amplification (ex. PCR) Glutamate dehydrogenase Toxigenic culture Toxic enzyme immunoassay (EIA) 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 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 All of the above Which agency regulates medical waste and incinerators? EPA Most common cause of early-onset neonatal meningitis is maternal transmission of: Neisseria gonorrhoeae Group B streptococcus Cytomegalovirus Toxoplasma gondii Epi curve that rises slowly and then plateaus most likely represents: Common continuous exposure Common intermittent exposure Prpagated source Point source If a mother is pumping breast milk, what is the optimal time that milk should be stored in fridge at 4 degrees C? 72 hours Which indicator is likely to require longest time period for collection of surveillance data? CLABSI CAUTI CDI VRSA Infection is rare, so likely to require longest time to determine rates of infection, usual rates of occurrence, etc Purpose of the just-in-time inventory concept is to: Minimize costs of inventory Maintain better control of inventory Prevent waste of medical supplies Ensure adequate stock of medical supplies Steps to reduce peritoneal dialysis catheter-associated infections include: 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 What clinical manifestation in a pediatric patient should give an IP a high index of suspicion for chicken pox?: A. Lesions first appear on the face or trunk B. Lesions first appear in the throat or mouth C. Bright red rash that appears on the cheeks D. Inflamed, red or peeling skin on knees and elbows Select ALL the conditions that warrant airborne precautions: A. Norovirus B. Hepatitis A C. Measles D. Varicella E. Disseminated Varicella Zoster F. Tuberculosis G. Whooping Cough H. RSV I. Epiglottitis Koplik spots are a symptom that is specific to which of the following viruses: a. Varicella b. Rubella c. Rubeola (10 day measles) d. Coxsackievirus Anti-HBc indicates: a. Prior infection with Hepatitis B. b. Status as a Hepatitis B carrier. c. New infection with Hepatitis B. d. Prior immunization with Hepatitis B vaccine. Serologic markers of a recent infection include: a. IgG b. IgM c. IgA d. IgC A gram stain of cerebrospinal fluid showing gram negative diplococci strongly suggest which of the following: a. Aseptic Meningitis b. Pneumococcal disease c. Meningococcal disease d. H. influenzae disease The first step in an outbreak investigation is: a. Develop a case definition. b. Begin case finding. c. Confirm the outbreak. d. Notify senior leadership. Surveillance is defined as: a. Systematic collection of data for reporting. b. Focused data collection to detect problems. c. Targeted collection of data for quality assurance. d. Systematic collection of data for planning, implementation, and evaluation. Endemic infections are those infections that occur in a population: [Show Less]
