CBIC CIC Exam With Confidence Using Practice Dumps

Pregnant healthcare workerswho are not immune to varicella (chickenpox)are atincreased risk for severe complicationsif infected. These employees should be excluded from areas like pediatrics where exposure risk is elevated.

TheAPIC Textspecifies:

“Healthcare personnel who are not immune to varicella should avoid exposure to patients with active disease. In high-risk areas such as pediatrics, nonimmune pregnant employees should be reassigned”.

TheCIC Study Guidealso supports work exclusion or reassignment of nonimmune pregnant staff who have had exposure to varicella or are at risk.

Explanation of incorrect options:

A. Pregnant employees rarely require reassignment– False; reassignment is required in specific high-risk scenarios.

B. Hepatitis B surface antibody positivitymeans the employee is immune and can care for HBV patients.

C. Broad exclusion from all infected patientsis unnecessary and impractical.

The interaction between pathogens and the human body can take various forms, each with distinct immunological and clinical implications. The Certification Board of Infection Control and Epidemiology (CBIC) emphasizes understanding these states within the "Identification of Infectious Disease Processes" domain to guide infection prevention strategies. The question describes a scenario where pathogens are present, can be cultured (indicating viable organisms), but do not trigger a response from the body’s defense mechanisms, such as inflammation or immune activation. This requires identifying the appropriate microbiological state.

Option A, "Colonization," is the correct answer. Colonization occurs when microorganisms are present on or in the body (e.g., skin, mucous membranes, or gut) without causing harm or eliciting an immune response. These pathogens can be cultured, as they are alive and replicating, but they exist in a commensal or symbiotic relationship with the host, not provoking symptoms or defense mechanisms. Examples include normal flora like Staphylococcus epidermidis on the skin or Streptococcus salivarius in the oral cavity. The Centers for Disease Control and Prevention (CDC) defines colonization as the presence of microbes without tissue invasion or damage, distinguishing it from infection (CDC, "Principles of Epidemiology in Public Health Practice," 3rd Edition, 2012).

Option B, "Infection," is incorrect because it involves the invasion and multiplication of pathogens in body tissues, leading to an immune response, such as inflammation, fever, or antibody production. This contrasts with the question’s description of no defense mechanism response. Option C, "Latency," refers to a state where a pathogen (e.g., herpes simplex virus or Mycobacterium tuberculosis) remains dormant in the body after initial infection, capable of reactivation but not eliciting an active immune response during dormancy. However, latency implies a prior infection with a latent phase, whereas the question suggests a current, non-responsive state without prior infection context. Option D, "Contamination," describes the unintended presence of pathogens on inanimate objects or surfaces (e.g., medical equipment), not within the body, and does not align with the scenario of living, culturable pathogens in a host.

The CBIC Practice Analysis (2022) and CDC guidelines highlight colonization as a key concept in infection control, particularly in settings like hospitals where colonized patients can serve as reservoirs for potential infections. The absence of an immune response, as specified, aligns with the definition of colonization, making Option A the most accurate answer.

Thawingraw meat at room temperatureis amajor food safety violationbecause it allows bacteria to multiply rapidly within thetemperature danger zone(40–140°F or 4.4–60°C).Meat should always be thawed in the refrigerator, under cold running water, or in a microwave if cooked immediately.

Why the Other Options Are Incorrect?

B. Using a cutting board to cut vegetables– This issafeas long as proper cleaning and sanitation procedures are followed.

C. Maintaining hot food at 145°F (62.7°C) during serving–145°F is an acceptable minimum temperaturefor certain meats likebeef, fish, and pork.

D. Discarding most perishable food within 72 hours– Many perishable foods, especially leftovers, should be discardedwithin 3 days, making this an appropriate practice.

CBIC Infection Control Reference

The APIC guidelinesemphasize thatraw meat should never be thawed at room temperaturedue to the risk ofbacterial growth and foodborne illness​.
