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.

The anterior chest wall and abdomen accounts for 18%, the left upper limb 9 % (4.5% anteriorly and 4.5% posteriorly), and the right upper limb 4.5% (2.25% anteriorly and 2.25% posteriorly).
(18+9+4.5) =31.5%
Correct Answer is A
Explanation
This is because pulmonary tuberculosis causes inflammation and damage to the lungs, which reduces oxygen exchange and leads to fatigue and weakness.
