Final answer:
The first step in evaluating Mr. Kenta's symptoms would be to conduct a tuberculin skin test and take an x-ray of his chest to determine if he has tuberculosis or any other respiratory infection.
Step-by-step explanation:
Based on the symptoms described, Mr. Kenta may be suffering from a serious respiratory infection. One possible cause of his symptoms could be tuberculosis (TB), a bacterial infection that can cause persistent coughing, night sweats, weight loss, and the coughing up of blood. To determine if Mr. Kenta has TB, a tuberculin skin test should be conducted. This test involves injecting a small amount of purified protein derivative (PPD) under the skin of the forearm and then monitoring for a reaction.
Additionally, it would be prudent to take an x-ray of Mr. Kenta's chest. This can help identify any abnormalities or signs of infection that may be present in the lungs.
The dental issues that Mr. Kenta is experiencing are separate from his respiratory symptoms and should be addressed separately. As a result, the first step in his medical evaluation would be to perform the tuberculin skin test and take an x-ray of his chest.
