A nurse in a clinic is collecting a history from a client who reports that a member of his family just received a diagnosis of pulmonary tuberculosis. The nurse should expect that the provider will prescribe which of the following diagnostic tests first?
Nucleic acid amplification test (NAAT)
Sputum culture for acid-fast bacillus (AFB)
Chest x-ray
CT scan
The Correct Answer is A
This is because a NAAT can detect the presence of Mycobacterium tuberculosis DNA in a sputum sample within hours, which can confirm the diagnosis and guide treatment decisions. A sputum culture for AFB can take several weeks to yield results, while a chest x-ray or a CT scan can only show suggestive findings but not confirm the diagnosis.

Correct Answer is B
Explanation
This is because Western blot analysis detects specific antibodies to HIV antigens and has a high specificity and sensitivity for HIV infection. CD4+ T-cell count measures the number of helper T cells in the blood and indicates the degree of immunosuppression in clients with HIV infection, but it does not confirm the diagnosis. Quantitative RNA assay and viral load test measure the amount of HIV RNA in the blood and indicate the level of viral replication and response to antiretroviral therapy, but they do not confirm the diagnosis.
Correct Answer is D
Explanation
The correct answer is choiceD. Fresh flowers and potted plants in the room.
Choice A rationale:
While activities that could result in bleeding should be avoided in patients with low platelet counts, this is not directly related to neutropenia.Neutropenia primarily increases the risk of infection rather than bleeding.
Choice B rationale:
Restricting oral fluid intake to between meals is not relevant to managing neutropenia.Adequate hydration is important, but the timing of fluid intake does not impact neutropenia management.
Choice C rationale:
While limiting visitors can help reduce the risk of infection, it is not necessary to restrict all visitors.Instead, visitors should follow strict hygiene practices, such as handwashing and wearing masks, to minimize infection risk.
Choice D rationale:
Fresh flowers and potted plants can harbor bacteria and fungi, which pose a significant infection risk to neutropenic patients.Therefore, these should be avoided in the patient’s room.
