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

Answer and Explanation

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","C","D","F"]

Explanation

A. While it's important for older adults to have regular blood tests to monitor their health, showing expected changes in white blood cell counts is not a specific risk factor for infections.
B. Skin tests for tuberculosis may be falsely negative in older adults due to a weakened immune response.
C. Older adults should stay up-to-date on their vaccinations, including influenza, pneumococcal, and shingles vaccinations, to help protect themselves against these infections.
D. Older adults are at increased risk for respiratory tract infections, such as pneumonia, and genitourinary infections, such as urinary tract infections.
E. Booster vaccinations are essential for older adults to maintain protection against diseases such as influenza, tetanus, diphtheria, and pertussis.
F. Older adults may not develop a fever in response to a severe infection. This can make it difficult to recognize the presence of an infection.

A. Neutropenia B. Anemia C. Leukopenia D. Left Shift

Correct Answer is D

Explanation

A. Neutropenia refers to an abnormally low level of neutrophils in the blood. This condition can result from various factors, including severe infections, bone marrow issues, or certain medications. However, in the context of a severe bacterial infection, you would expect an increase in neutrophils, not a decrease.
B. Anemia is a condition characterized by a lack of healthy red blood cells to carry adequate oxygen to the body’s tissues. While infections can lead to anemia, it is not a direct indicator of white blood cell production or response to a bacterial infection.
C. Leukopenia refers to a decrease in the overall white blood cell count. Like neutropenia, it indicates a reduced ability to fight infection, which is not consistent with a severe bacterial infection where the body is actively trying to produce more white blood cells.
D. A "left shift" indicates the presence of increased immature neutrophils (such as band cells) in the blood, which occurs when the bone marrow releases these cells into circulation in response to a severe infection. This reflects the body’s effort to combat an infection, typically seen in bacterial infections.
