Final answer:
True, patients with meningococcal pneumonia should be isolated before performing oral hygiene and given antimicrobial therapy post-isolation, while hydration should be maintained to reduce infection risk.
Step-by-step explanation:
The statement 'The nurse should isolate the patient before performing oral hygiene. The nurse should provide antimicrobial therapy after isolating the patient. The nurse should maintain adequate hydration to promote the patients' health and reduce the risk of infections' is True. In cases of meningococcal pneumonia, which is a droplet infection, isolation is crucial to prevent transmission. Once isolated, appropriate antimicrobial therapy, such as the use of third-generation cephalosporins, is necessary, and maintaining hydration supports overall health and recovery. Prophylactic vaccination is also an effective prevention method against certain bacteria causing meningitis. Timely laboratory confirmation is essential to ensure the correct pathogens are targeted by treatment and to determine if prophylactic measures are needed for close contacts.
