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.

Malignant melanoma is a rare but aggressive type of skin cancer that originates from melanocytes, the cells that produce pigment in the skin. It can appear as a new or changing mole that has an irregular shape, uneven color, large size, or bleeding tendency. It may also be purplish in color due to vascular invasion or hemorrhage within the lesion.
