CIC Exam Dumps : CBIC Certified Infection Control Exam

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.

Group B Streptococcus (Streptococcus agalactiae) is the most common cause ofneonatal bacterial meningitisbeyond one week of age.

Step-by-Step Justification:

Group B Streptococcus (GBS) and Neonatal Infections:

GBS is aleading cause of late-onset neonatal meningitis(occurringafter 7 days of age)​.

Infection typically occursthrough vertical transmission from the mother or postnatal exposure.

Neonatal Risk Factors:

Premature birth, prolonged rupture of membranes, and maternal GBS colonization increase risk​.

Why Other Options Are Incorrect:

A. Group A:Rare in neonates and more commonly associated with pharyngitis and skin infections.

C. Group C:Typically associated withanimal infectionsand rarely affects humans.

D. Group D:IncludesEnterococcus, which can cause neonatal infections but isnot the most common cause of meningitis.

The human immunodeficiency virus (HIV) and Hepatitis B virus (HBV) are both bloodborne pathogens that pose significant risks in healthcare settings, and understanding their similarities is crucial for infection prevention and control. The Certification Board of Infection Control and Epidemiology (CBIC) emphasizes the importance of recognizing transmission modes and implementing appropriate precautions in the "Prevention and Control of Infectious Diseases" domain, aligning with guidelines from the Centers for Disease Control and Prevention (CDC). Comparing these viruses involves evaluating their epidemiology, transmission routes, and occupational risks.

Option C, "Transmission may occur from asymptomatic carriers," is the correct answer. Both HIV and HBV can be transmitted by individuals who are infected but show no symptoms, making asymptomatic carriage a significant similarity. For HBV, chronic carriers (estimated at 257 million globally per WHO, 2019) can transmit the virus through blood, semen, or other bodily fluids without overt signs of disease. Similarly, HIV-infected individuals can remain asymptomatic for years during the latent phase, yet still transmit the virus through sexual contact, blood exposure, or perinatal transmission. The CDC’s "Guidelines for Prevention of Transmission of HIV and HBV to Healthcare Workers" (1987, updated 2011) and "Epidemiology and Prevention of Viral Hepatitis" (2018) highlight this shared characteristic, underscoring the need for universal precautions regardless of symptom status.

Option A, "The primary mechanism of transmission for both is maternal-fetal," is incorrect. While maternal-fetal transmission (perinatal transmission) is a significant route for both HIV and HBV—occurring in 5-10% of cases without intervention for HBV and 15-45% for HIV without antiretroviral therapy—it is not the primary mechanism. For HBV, the primary mode is horizontal transmission through unprotected sexual contact or percutaneous exposure (e.g., needlesticks), accounting for the majority of cases. For HIV, sexual transmission and intravenous drug use are the leading modes globally, with maternal-fetal transmission being a smaller proportion despite its importance. Option B, "Needlestick exposure leads to a high frequency of healthcare workerinfection," is partially true but not a precise similarity. Needlestick exposures carry a high risk for HBV (transmission risk ~30% if the source is HBeAg-positive) and a lower risk for HIV (~0.3%), but the frequency of infection among healthcare workers is significantly higher for HBV due to its greater infectivity and stability outside the host. This makes the statement more characteristic of HBV than a shared trait. Option D, "The risk of infection from mucous membrane exposure is the same," is false. The risk of HIV transmission via mucous membrane exposure (e.g., splash to eyes or mouth) is approximately 0.09%, while for HBV it is higher (up to 1-2% depending on viral load and exposure type), reflecting HBV’s greater infectivity.

The CBIC Practice Analysis (2022) and CDC guidelines emphasize the role of asymptomatic transmission in shaping infection control strategies, such as routine testing and post-exposure prophylaxis. This shared feature of HIV and HBV justifies Option C as the most accurate similarity.
