Working with public health agencies to collect and analyze indicators that might signal an increase in community illness is an example of which type of surveillance?
Correct Answer: C
Surveillance is a critical tool in infection prevention and control, used to monitor disease trends and guide public health responses. The Certification Board of Infection Control and Epidemiology (CBIC) emphasizes the "Surveillance and Epidemiologic Investigation" domain, which aligns withthe Centers for Disease Control and Prevention (CDC) "Principles of Epidemiology in Public Health Practice" (3rd Edition, 2012). The question describes a process of collecting and analyzing indicators to signal an increase in community illness, requiring identification of the appropriate surveillance type among the options provided. Option C, "Syndromic," is the correct answer. Syndromic surveillance involves monitoring non-specific health indicators or symptoms (e.g., fever, respiratory complaints, or gastrointestinal issues) that may precede a formal diagnosis, aiming to detect potential outbreaks or increases in community illness early. The CDC defines syndromic surveillance as the real-time or near-real-time collection, analysis, and interpretation of health-related data to provide actionable information, often in collaboration with public health agencies. This approach uses data from sources like emergency department visits, over-the-counter medication sales, or absenteeism reports to identify trends before laboratory confirmation, making it well-suited to the described scenario of signaling community illness increases. Option A, "Passive," involves healthcare providers or laboratories reporting cases to public health authorities on a voluntary or mandatory basis without active prompting (e.g., routine notifiable disease reporting). While passive surveillance contributes to baseline data, it is less proactive and not specifically designed to signal early increases in illness, making it less fitting. Option B, "Active," entails public health officials actively seeking data from healthcare facilities or providers (e.g., calling to confirm cases during an outbreak). This is more resource-intensive and typically used for specific investigations rather than ongoing community trend monitoring, which aligns better with syndromic methods. Option D, "Targeted," refers to surveillance focused on a specific population, disease, or event (e.g., monitoring TB in a high-risk group). The scenario's broad focus on community illness indicators does not suggest a targeted approach. The CBIC Practice Analysis (2022) and CDC guidelines highlight syndromic surveillance as a key strategy for early detection of community-wide health threats, often involving collaboration with public health agencies. Option C best matches the described activity of analyzing indicators to signal illness increases, making it the correct choice. References: CBIC Practice Analysis, 2022.

Question 27
The MOST important characteristic to include when using a template for a comprehensive annual risk assessment is
Correct Answer: C
Acomprehensive annual risk assessmentshould focus onfacility-specificfactors, includingpatient population, infection trends, and operational risks. Why the Other Options Are Incorrect? * A. System strategic goals and objectives- Whileimportant, goals should alignwith facility-specific infection risks. * B. Cost savings attributed to infection control- Cost considerations aresecondary to risk assessment . * D. Statewide communicable disease and HAI data-Broader epidemiological data is usefulbut should complement, not replace,facility-specificdata. CBIC Infection Control Reference APIC emphasizes thatfacility-specific infection data is essential for an effective risk assessment.
Question 28
Which of the following strategies is MOST effective in reducing surgical site infections (SSI) in orthopedic procedures?
Correct Answer: A
* Perioperative normothermia maintenance reduces SSI rates by improving immune function and tissue perfusion. * Routine wound irrigation (B) has no strong evidence supporting SSI prevention. * Prolonged antibiotic use (C) increases antibiotic resistance without added benefit. * Extended use of wound dressings (D) does not reduce SSI rates. CBIC Infection Control References: * APIC Text, "SSI Prevention in Surgery," Chapter 12.
Question 29
A patient with a non-crusted rash has boon diagnosed with Sarcoptes scabiei. The patient is treated with 5% permethrin and precautions are started. The precautions can be stopped
Correct Answer: C
For Sarcoptes scabiei (scabies), Contact Precautions should remain in place until 24 hours after effective treatment has been completed. The first-line treatment is 5% permethrin cream, which is applied to the entire body and left on for 8-14 hours before being washed off. Why the Other Options Are Incorrect? * A. When the treatment cream is applied - The mite is still present and infectious until treatment has fully taken effect. * B. When the bed linen is changed - While changing linens is necessary, it does not indicate that the infestation has cleared. * D. 24 hours after the second treatment - Most cases require only one treatment with permethrin, though severe cases may need a second dose after a week. CBIC Infection Control Reference According to APIC guidelines, Contact Precautions can be discontinued 24 hours after effective treatment has been administered.
Question 30
Which of the following options describes a correct use of personal protective equipment?
Correct Answer: B
According to CDC and APIC guidelines, a surgical mask is required when performing lumbar punctures to prevent bacterial contamination (e.g., meningitis caused by droplet transmission of oral flora). Why the Other Options Are Incorrect? * A. Personal eyeglasses should be worn during suctioning - Incorrect because eyeglasses do not provide adequate eye protection. Goggles or face shields should be used. * C. Gloves should be worn when handling or touching a cardiac monitor that has been disinfected - Not necessary unless recontamination is suspected. * D. Eye protection should be worn when providing patient care after unprotected exposure - Eye protection should be used before exposure, not just after. CBIC Infection Control Reference APIC states that surgical masks must be worn for procedures such as lumbar puncture to reduce infection risk.
