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 C
Explanation
This is because talking with the client can help reduce anxiety, pain, and isolation, as well as build trust and rapport between the nurse and the client. Talking with the client can also provide an opportunity for education, feedback, and encouragement.
Correct Answer is C
Explanation
An escharotomy is a surgical procedure that involves making incisions in the eschar, which is the hard, blackened tissue that forms over a severe burn wound. The eschar can restrict blood flow and cause compartment syndrome, which can lead to tissue necrosis and nerve damage. By cutting through the eschar, the pressure is relieved and circulation is restored. This procedure does not involve removing the dead tissue, which is done by debridement or hydrotherapy. A skin graft is a different procedure that involves transplanting healthy skin from another site to cover a burn wound.
