CIC Studying 2023: CIC Practice Exam Questions

CIC Studying: CIC Practice Exam Questions Recipients of allogenic hematopoeietic stem transplantation (HSCT) should be placed in rooms with how many air exchanges per hour? 3 5 10 12 - 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 - Maximum 12 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 - Handwashing 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 - Infant colonized with S. aureus. 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 - 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 - I - annually and III - when risks 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 - 3 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 - Arteriovenous fistula. 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 - Pneumococcal vaccine, influenza vaccine, smoking cessation The best time to collect a sputum specimen for acid-fast bacilli is: Early morning Midday Afternoon Bedtime - Early morning 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 - 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 - 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
