As a nurse, you understand that when patients have latent TB:
They will be treated with medications for 2 years
They will always test negative on a Mantoux test
They can spread it to others until they have 3 negative sputum tests
They can't spread it to others
The Correct Answer is D
A. While patients with latent TB may be treated to prevent progression to active TB, the treatment duration is generally shorter—typically around 3 to 9 months, depending on the medication regimen (e.g., isoniazid for 9 months or rifampin for 4 months).
B. Individuals with latent TB will usually test positive on a Mantoux test (also known as a tuberculin skin test), indicating they have been exposed to the TB bacteria. However, those with latent TB do not have active disease and may not have symptoms.
C. Individuals with latent TB do not spread the bacteria to others because the infection is contained and does not cause active disease. Only those with active TB can transmit the bacteria, regardless of sputum test results.
D. Patients with latent TB are not contagious and cannot spread the bacteria to others. The bacteria remain inactive in the body, and only a small percentage of these individuals may develop active TB in the future.

Correct Answer is B
Explanation
A. While rinsing fruits is good practice, it may not fully eliminate the risk of pathogens, especially for someone with a compromised immune system.
B. This statement is the best indication of understanding how to prevent infections. Changing kitty litter can expose the client to Toxoplasma gondii, which is particularly risky for immunocompromised individuals. Wearing gloves is a direct and effective precaution.
C. Although wearing an N95 mask can be appropriate in certain situations, it may not be necessary for all interactions with sick family members. A standard surgical mask is often sufficient.
D. Cooking vegetables is a good practice for food safety, especially for immunocompromised individuals, but this statement is more general than specifically addressing a particular risk.
Correct Answer is C
Explanation
A. Proper wound care is essential in preventing infections, particularly in older adults who may have thinner skin and slower healing processes. However, while this is important, it is just one aspect of a comprehensive infection prevention strategy and does not address broader systemic issues.
B. Older adults are often at higher risk for infections due to waning immunity. Regular vaccinations, such as the flu vaccine, pneumococcal vaccine, and others, can significantly reduce the risk of serious infections. This action is critical but is part of a preventive framework rather than a standalone solution.
C. Hand hygiene is one of the most effective measures to prevent the transmission of infections. Educating clients about proper handwashing techniques and when to wash their hands can significantly reduce the risk of infections, especially in older adults who may be more susceptible due to age-related immune changes.
D. Nutrition plays a vital role in maintaining overall health and supporting the immune system. A well- balanced diet can help older adults fight infections more effectively. However, while important, diet alone may not be as immediately impactful in preventing infections as other measures like hand hygiene and vaccination.
