CIC Exam Dumps : CBIC Certified Infection Control Exam

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​.

Before initiating airborne precautions, the infection preventionist must first confirm the clinical suspicion of active TB.

Step-by-Step Justification:

Confirming Active TB:

A positive tuberculin skin test (TST) alone does not indicate active disease​.

A review of chest X-ray, symptoms, and risk factors is needed.

Medical Record Review:

Past TB history, imaging, and sputum testing are key to diagnosis​.

Not all TST-positive patients require isolation.

Why Other Options Are Incorrect:

A. Contact the roommate's physician to initiate TST: Premature, as no confirmation of active TB exists yet.

C. Report findings to Employee Health for staff follow-up: Should occur only after TB confirmation.

D. Transfer to airborne isolation immediately: Airborne isolation is necessary only if active TB is suspected based on clinical findings​.

The table separates admission cultures from weekly cultures, which is a common surveillance approach to distinguish imported MRSA burden (present on admission) from healthcare acquisition (newly detected later). The admission culture percent positive rises over the three months: 14% (Feb) → 18% (Mar) → 19% (Apr). That pattern indicates an increasing admission prevalence (option B). NHSN MDRO surveillance methods describe admission prevalence as a proxy measure using admission-related data to quantify organisms present at the time of entry into a location/facility.

By contrast, weekly culture positivity—often used as a proxy for on-unit acquisition/transmission when admission screening is in place—decreases: 6% → 5.6% → 4%, so option A is not increasing. The dataset also does not provide information about MRSA infections versus colonization (so C cannot be concluded), nor does it provide a denominator for “compliance” (e.g., expected admissions/weekly screens completed), so D cannot be determined. This interpretation aligns with standard infection prevention use of MRSA surveillance data to track prevalence (burden) versus incidence/acquisition.
