Explain how you would respond to the scenario as an advanced practice nurse using evidence-based practice guidelines and applying ethical considerations. 

In scenario three, the patient is a 44 year old female who has been experiencing chest pains for several days. As an advanced practice nurse it is important to assess the patient through gathering health assessment information that will support in making an accurate diagnosis. The first step would be performing a physical assessment to determine if there are any notable signs or indications that may contribute to the symptom of chest pain. During this process I would check her vital signs, heart rate and rhythm, respiratory rate, oxygen saturation levels as well as observable physical changes such as swelling or discoloration around her torso area. Furthermore, I would inquire about any other factors such as diet and lifestyle habits (smoking/alcohol) as well as current medications she may be taking which could affect overall health.

Given the nature of her condition it would also be pertinent to perform some laboratory testing in order to gain more insight into what could possibly causing her symptoms. In addition it’s important that diagnostic imaging tests such Angiogram, CT scan or X-ray should be conducted so further visual observations can made in relation possible source of discomfort . Finally additional assessments like EKG electrocardiogram Holter monitor cardiac enzyme stress test may need done depending extent complexity case observe development over time gather data correlate findings complete picture situation being looked at.

Once all relevant information has been collected using evidence based practices and clinical guidelines then a differential diagnosis can set forth with appropriate action plan devised best course treatment – This where ethical considerations come play considering medical interventions available no two patients always respond same manner risks benefits must weighed out determine right path forward individual see how decisions weighing those options ultimately shape outcome impacting life quality standards living acuity leaving nurse take responsibility working closely team members ensure most effective results achieved while protecting rights each unique party involved.
