This course prepares nurses, nursing assistants, home health aides, and other in-home caregivers to recognize, prevent, and respond to tuberculosis (TB) in private residences. It explains how TB spreads, the difference between latent TB infection and active TB disease, and what PPD skin tests and TB blood tests can and cannot show. Learners apply this knowledge to daily home care work, including reporting symptoms, responding to possible exposure, protecting vulnerable clients, and understanding the Florida nurse registry requirement for documentation of freedom from communicable disease.
Developed by: Scott Strachan RN, BSN
Target Audience
Registered nurses, licensed practical nurses, certified nursing assistants, home health aides, personal care aides, companions, homemakers, and other caregivers providing services in private residences.
Teaching Method
Self-directed learning completed independently, with scenario-based reflection.
Overview
Tuberculosis remains a public health concern in home care. Many clients receiving care at home are older adults or people with chronic illness or weakened immune systems, which places them at higher risk if they are exposed. Caregivers also work in close contact, often in small rooms with limited ventilation, during bathing, dressing, transfers, and meals.
This course focuses on the practical knowledge a caregiver needs to protect clients and themselves. It covers how TB is transmitted through the air, why a person with latent TB infection is not contagious, and which symptoms of active TB disease should be reported promptly. It explains how the tuberculin skin test (PPD or TST) and interferon-gamma release assay (IGRA) blood tests work, why results can be falsely positive or falsely negative, and what follow-up evaluation is expected after a positive result.
The course then applies this knowledge to the home setting, including infection prevention measures, the limits of ordinary masks compared with fit-tested respirators, exposure reporting, and role boundaries. Caregivers observe and report. They do not diagnose TB or decide when a person is no longer infectious.
A Florida-specific section explains the nurse registry requirement that referred independent contractors provide documentation that they are free from communicable diseases. It clarifies the difference between that documentation requirement and a specific TB test, a distinction that matters for caregivers with prior BCG vaccination or a previously documented positive test. Realistic scenarios throughout the course help learners apply sound judgment to situations they are likely to encounter.
The course includes ten instructional sections:
Reading, scenario reflection, and the post-test are designed for approximately 120 minutes of learner engagement.
