A patient with meningococcal meningitis experiences cardiac arrest. A nurse administers mouth-to-mouth breathing during CPR. Which of the following actions should the nurse take immediately?
The CBIC Certified Infection Control Exam Study Guide (6th edition) identifies Neisseria meningitidis as a highly transmissible organism spread through respiratory droplets and direct contact with oral secretions. Healthcare personnel who have unprotected, close exposure—such as mouth-to-mouth resuscitation—to a patient with meningococcal meningitis are considered high-risk contacts.
In this scenario, the nurse had direct exposure to respiratory secretions during CPR, which constitutes a significant risk for transmission. The Study Guide emphasizes that postexposure chemoprophylaxis is indicated as soon as possible, ideally within 24 hours of exposure, to prevent invasive meningococcal disease. Recommended prophylactic agents include rifampin, ciprofloxacin, or ceftriaxone, depending on contraindications and institutional protocols.
Option A is incorrect because chlorhexidine oral rinse does not eliminate systemic infection risk. Option B is inappropriate because quarantine is not required for exposed healthcare workers who receive appropriate prophylaxis. Option D is insufficient, as monitoring alone does not adequately reduce the risk of developing disease following high-risk exposure.
Rapid initiation of chemoprophylaxis is a critical infection prevention intervention and a high-yield CIC® exam concept. Early action protects the exposed healthcare worker and prevents secondary transmission within the healthcare setting.
