Which vaccines does a nursing assistant need if she has had the flu, chickenpox, and tuberculosis in childhood but has not received any vaccines?

The correct answer identifies the vaccines that are crucial for a nursing assistant's role to ensure the safety and health of both the assistant and the patients they may come into contact with.

Hepatitis B is particularly important because nursing assistants are often exposed to blood and bodily fluids, and this vaccine is essential for anyone working in healthcare settings to prevent the transmission of the virus. Hepatitis A vaccination is also important as it helps protect against a disease spread through contaminated food and water, which is relevant in healthcare environments.

Influenza vaccination is vital since nursing assistants frequently work with vulnerable populations, including the elderly and those with compromised immune systems. The annual flu shot helps reduce the risk of outbreaks in healthcare facilities and protects these high-risk groups.

The inclusion of MMR (measles, mumps, rubella) in the vaccine regimen is necessary as these diseases can spread quickly, and vaccination is essential for preventing outbreaks, especially in group living situations or among populations with lower immunization rates.

The other options do not provide a comprehensive approach to the specific needs of a nursing assistant. For example, while the varicella (chickenpox) vaccination is important for someone who had chickenpox, it does not cover the broad spectrum of vaccines recommended for healthcare workers
