Answer:
Options B, C, and D -- nausea, fatigue, and muscle pain
Explanation:
Though the terms signs and symptoms are sometimes used interchangeably, such practice is technically incorrect.
Signs are objective pieces of data gathered during assessment that can be observed by the healthcare personnel using various tools and techniques. For example, a blood pressure cuff and sphygmomanometer can be used to determine if a patient is experiencing alterations in blood pressure; a thermometer can determine if the patient's temperature has strayed away from the expected 98.6°F or 37°C.
Symptoms are subjective pieces of data gathered by asking the patient questions, the answers to which vary from patient to patient because only the patient themselves can tell healthcare personnel how they feel. There may be signs of nausea such as changes in the color of the skin, but only the patient can accurately tell the staff they are feeling nauseous. The patient may grimace as a sign of pain, but only they can definitively tell the medical team the severity of the pain, where the pain is, and how long it has been occurring.
Using these definitions, the choices can be parsed through to decide which represent symptoms. Namely, they are nausea, fatigue, and muscle pain. Nausea and pain of any kind were mentioned above, but to explain fatigue, only the patient can tell those in charge of their care that they have experienced a drop in energy that is a deviation from their baseline.
Fever can be determined whether the patient reports feeling warm to touch or not. Swelling, also known as edema, can be observed without the patient reporting a feeling of fullness in their extremities; edema within the lungs (pulmonary edema) can be auscultated (listened to) using a stethoscope, regardless of what the patient is feeling.
