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 A
Explanation
This is because aspirin can cause salicylate toxicity, which can manifest as tinnitus, hearing loss, vertigo, headache, confusion, and hyperventilation. The nurse should monitor the client's serum salicylate level and advise the client to report any signs of toxicity to the provider.
Correct Answer is B
Explanation
This is because the recommended tidal volume for mechanical ventilation is 6 to 8 mL/kg of ideal body weight. Therefore, for a client who has an ideal weight of 60 kg, the tidal volume should be between 360 and 480 mL. A tidal volume that is too high or too low can cause lung injury or hypoventilation.
