Final answer:
A nurse includes symptoms, medical history, and examination findings in the diagnosis of a patient, as seen in the case of John who presents with multiple symptoms and fever. Additional tests would be considered, and the treatment plan would be based on the nursing diagnosis and specific patient needs, such as dialysis.
Step-by-step explanation:
When caring for a client, the nurse would include observations and data related to the patient's chief concern in the diagnosis. This may encompass clinical symptoms, medical history, and any physical examination findings relevant to the current condition. For instance, in a clinical focus case where a 65-year-old man named John reports symptoms such as headache, chest pain, coughing, shortness of breath, nausea, and diarrhea, and is found to have a high fever, these facts form the basis of the nursing diagnosis.
Further, under the direct supervision of a registered nurse, the nurse's role extends to providing specialized treatments, such as dialysis, which includes assessing and responding to patient needs. The comprehensive appraisal of the patient, considering medical history and current complaints, leads to a more accurate nursing diagnosis, which is pivotal for devising an appropriate treatment plan.
In the context of the given clinical focuses, additional tests might include blood work, imaging, or specific diagnostic tests for conditions that could be causing John's symptoms. The recommended treatment would likely be tailored to the preliminary diagnosis, which could be an infection given the fever, or perhaps a respiratory or gastrointestinal illness based on John's symptoms.
