CBIC CIC Exam With Confidence Using Practice Dumps

Meningococcal infections, such asNeisseria meningitidis, are transmitted viarespiratory droplets. According toAPIC and CDC guidelines, patients withmeningococcal diseaseshould be placed onDroplet Precautions upon admission. These precautions can bediscontinued after 24 hours of effective antibiotic therapy.

Why the Other Options Are Incorrect?

B. Droplet precautions must continue–Droplet Precautions are not needed beyond 24 hours of appropriate therapybecause treatment rapidly reduces infectiousness.

C. Airborne precautions may be discontinued after 24 hours of therapy–Meningococcal infection is not airborne, soAirborne Precautions are never required.

D. Airborne precautions must continue–Incorrectbecausemeningococci do not transmit via airborne particles.

CBIC Infection Control Reference

According toAPIC guidelines,Droplet Precautions should be maintained for at least 24 hours after effective antibiotic therapy initiation​.

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

Step-by-Step Justification:

Gram Stain Interpretation:

Gram-negative diplococciin CSF strongly suggestNeisseria meningitidis​.

Classic Symptoms of Meningitis:

Fever,stiff neck, and vomiting are hallmark signs ofmeningococcal 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.

A patient withpertussis(whooping cough) should remain onDroplet Precautionsto prevent transmission. According toAPIC guidelines, patients with pertussis can be removed from Droplet Precautionsafter completing at least five days of appropriate antimicrobial therapy and showing clinical improvement.

Why the Other Options Are Incorrect?

A. Direct fluorescent antibody and/or culture are negative– Laboratory results may not always detect pertussis early, and false negatives can occur.

C. The patient has been given pertussis vaccine– The vaccinepreventsbut does not treat pertussis, and it does not shorten the period of contagiousness.

D. The paroxysmal stage has ended– Theparoxysmal stage(severe coughing fits) can last weeks, butinfectiousness decreaseswith antibiotics.

CBIC Infection Control Reference

According toAPICguidelines, Droplet Precautions should continue until the patient has received at leastfive days of antimicrobial therapy​.
