Correct Answer is A
Explanation
Choice A rationale
Discrimination refers to the unjust or prejudicial treatment of different categories of people, especially on the grounds of race, age, or sex. In this case, the physician is refusing to use a translator and only provides materials in English to patients who may not understand the language. This action can be seen as discriminatory because it denies these patients the same level of care that English-speaking patients receive.
Choice B rationale
Ethnocentrism is the belief in the inherent superiority of one’s own ethnic group or culture. While the physician’s actions may seem ethnocentric, as they are not considering the cultural needs of their patients, the scenario does not provide enough information to definitively label the behavior as such.
Choice C rationale
Stereotyping involves generalized and oversimplified beliefs about a particular group. The physician’s actions do not necessarily indicate that they are stereotyping their patients, but rather that they are not providing equitable care.
Choice D rationale
Acculturation is the process of adopting the cultural traits or social patterns of another group. The physician’s actions do not demonstrate acculturation. Instead, they show a lack of willingness to accommodate the cultural and linguistic needs of their patients.
Correct Answer is A
Explanation
Choice A rationale
Fatigue is a subjective symptom because it is experienced and reported by the patient. Patients with left-sided heart failure often experience fatigue due to the heart’s inability to pump sufficient blood to meet the body’s needs.
Choice B rationale
Elevated pulmonary capillary wedge pressure is an objective symptom that can be measured and observed by healthcare professionals. It is not something that a patient can directly experience or report.
Choice C rationale
Orthopnea, or difficulty breathing when lying flat, is a subjective symptom as it is based on the patient’s personal experience. However, it is not the best answer in this case because the question asks for the “subjective symptoms,” and fatigue is a more common subjective symptom of left-sided heart failure.
Choice D rationale
Cyanosis, or bluish discoloration of the skin due to poor circulation or inadequate oxygenation of the blood, is an objective symptom that can be observed by healthcare professionals. It is not something that a patient can directly experience or report.
