The Gram stain showing Gram-negative diplococci in cerebrospinal fluid (CSF) is characteristic of Neisseria meningitidis, a leading cause of bacterial meningitis in adolescents and young adults.

Step-by-Step Justification:

Gram Stain Interpretation:

Gram-negative diplococci in CSF strongly suggest Neisseria meningitidis​.

Classic Symptoms of Meningitis:

Fever, stiff neck, and vomiting are hallmark signs of meningococcal meningitis.

Neisseria meningitidis vs. Other Bacteria:

Haemophilus influenzae (Option A) → Gram-negative coccobacilli.

Listeria monocytogenes (Option C) → Gram-positive rods.

Streptococcus pneumoniae (Option D) → Gram-positive diplococci.

APIC Ready Reference for Microbes, "Neisseria meningitidis and Meningitis"​.

Thawing raw meat at room temperature is a major food safety violation because it allows bacteria to multiply rapidly within the temperature 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 is safe as 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 temperature for certain meats like beef, fish, and pork.

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

CBIC Infection Control Reference

The APIC guidelines emphasize that raw meat should never be thawed at room temperature due to the risk of bacterial growth and foodborne illness​.

The correct answer is B, "1 and 4 only," indicating that the information can best be used to heighten awareness among Emergency Department (ED) staff and review the TB exposure control plan. According to the Certification Board of Infection Control and Epidemiology (CBIC) guidelines, tuberculosis (TB) remains a significant public health concern, particularly with the increasing proportion of cases among foreign-born persons in the United States. The data showing a rise from four to 22 states with over 50% of TB cases among foreign-born individuals highlights an evolving epidemiological trend that warrants targeted infection prevention strategies (CBIC Practice Analysis, 2022, Domain II: Surveillance and Epidemiologic Investigation, Competency 2.1 - Conduct surveillance for healthcare-associated infections and epidemiologically significant organisms).

Heightening awareness among ED staff (option 1) is critical because the ED is often the first point of contact for patients with undiagnosed or active TB, especially those from high-prevalence regions. Increased awareness can improve early identification, isolation, and reporting of potential cases. Reviewing the TB exposure control plan (option 4) is equally important, as it allows the infection preventionist to assess and update protocols—such as ventilation, personal protective equipment (PPE) use, and screening processes—to address the heightened risk posed by the growing number of cases among foreign-born individuals (CBIC Practice Analysis, 2022, Domain III: Infection Prevention and Control, Competency 3.2 - Implement measures to prevent transmission of infectious agents).

Option 2 (inform staff who are foreign-born) is not the best use of this data, as the information pertains to patient demographics rather than staff risk, and targeting staff based on their origin could be inappropriate without specific exposure evidence. Option 3 (educate patients and visitors) is a general education strategy but less directly actionable with this specific epidemiological data, which is more relevant to healthcare worker preparedness and facility protocols. Combining options 1 and 4 aligns with CBIC’s emphasis on using surveillance data to guide prevention and control measures, ensuring a proactive response to the increased TB burden (CBIC Practice Analysis, 2022, Domain II: Surveillance and Epidemiologic Investigation, Competency 2.5 - Use data to guide infection prevention and control strategies).
